x86:

* KVM currently invalidates the entirety of the page tables, not just
  those for the memslot being touched, when a memslot is moved or deleted.
  The former does not have particularly noticeable overhead, but Intel's
  TDX will require the guest to re-accept private pages if they are
  dropped from the secure EPT, which is a non starter.  Actually,
  the only reason why this is not already being done is a bug which
  was never fully investigated and caused VM instability with assigned
  GeForce GPUs, so allow userspace to opt into the new behavior.

* Advertise AVX10.1 to userspace (effectively prep work for the "real" AVX10
  functionality that is on the horizon).

* Rework common MSR handling code to suppress errors on userspace accesses to
  unsupported-but-advertised MSRs.  This will allow removing (almost?) all of
  KVM's exemptions for userspace access to MSRs that shouldn't exist based on
  the vCPU model (the actual cleanup is non-trivial future work).

* Rework KVM's handling of x2APIC ICR, again, because AMD (x2AVIC) splits the
  64-bit value into the legacy ICR and ICR2 storage, whereas Intel (APICv)
  stores the entire 64-bit value at the ICR offset.

* Fix a bug where KVM would fail to exit to userspace if one was triggered by
  a fastpath exit handler.

* Add fastpath handling of HLT VM-Exit to expedite re-entering the guest when
  there's already a pending wake event at the time of the exit.

* Fix a WARN caused by RSM entering a nested guest from SMM with invalid guest
  state, by forcing the vCPU out of guest mode prior to signalling SHUTDOWN
  (the SHUTDOWN hits the VM altogether, not the nested guest)

* Overhaul the "unprotect and retry" logic to more precisely identify cases
  where retrying is actually helpful, and to harden all retry paths against
  putting the guest into an infinite retry loop.

* Add support for yielding, e.g. to honor NEED_RESCHED, when zapping rmaps in
  the shadow MMU.

* Refactor pieces of the shadow MMU related to aging SPTEs in prepartion for
  adding multi generation LRU support in KVM.

* Don't stuff the RSB after VM-Exit when RETPOLINE=y and AutoIBRS is enabled,
  i.e. when the CPU has already flushed the RSB.

* Trace the per-CPU host save area as a VMCB pointer to improve readability
  and cleanup the retrieval of the SEV-ES host save area.

* Remove unnecessary accounting of temporary nested VMCB related allocations.

* Set FINAL/PAGE in the page fault error code for EPT violations if and only
  if the GVA is valid.  If the GVA is NOT valid, there is no guest-side page
  table walk and so stuffing paging related metadata is nonsensical.

* Fix a bug where KVM would incorrectly synthesize a nested VM-Exit instead of
  emulating posted interrupt delivery to L2.

* Add a lockdep assertion to detect unsafe accesses of vmcs12 structures.

* Harden eVMCS loading against an impossible NULL pointer deref (really truly
  should be impossible).

* Minor SGX fix and a cleanup.

* Misc cleanups

Generic:

* Register KVM's cpuhp and syscore callbacks when enabling virtualization in
  hardware, as the sole purpose of said callbacks is to disable and re-enable
  virtualization as needed.

* Enable virtualization when KVM is loaded, not right before the first VM
  is created.  Together with the previous change, this simplifies a
  lot the logic of the callbacks, because their very existence implies
  virtualization is enabled.

* Fix a bug that results in KVM prematurely exiting to userspace for coalesced
  MMIO/PIO in many cases, clean up the related code, and add a testcase.

* Fix a bug in kvm_clear_guest() where it would trigger a buffer overflow _if_
  the gpa+len crosses a page boundary, which thankfully is guaranteed to not
  happen in the current code base.  Add WARNs in more helpers that read/write
  guest memory to detect similar bugs.

Selftests:

* Fix a goof that caused some Hyper-V tests to be skipped when run on bare
  metal, i.e. NOT in a VM.

* Add a regression test for KVM's handling of SHUTDOWN for an SEV-ES guest.

* Explicitly include one-off assets in .gitignore.  Past Sean was completely
  wrong about not being able to detect missing .gitignore entries.

* Verify userspace single-stepping works when KVM happens to handle a VM-Exit
  in its fastpath.

* Misc cleanups

please pull a couple more s390 updates for the 6.12 merge window.

  the chacha20 implementation

- Add vfio-ap driver feature advertisement for use by libvirt and mdevctl

Modules changes for v6.12-rc1

There are a few fixes / cleanups from Vincent, Chunhui, and Petr, but the
most important part of this pull request is the Rust community stepping
up to help maintain both C / Rust code for future Rust module support. We
grow the set of modules maintainers by 3 now, and with this hope to scale to
help address what's needed to properly support future Rust module support.

A lot of exciting stuff coming in future kernel releases.

This has been on linux-next for ~ 3 weeks now with no issues.

This pull request contains the following changes for UML:

- Removal of dead code (TT mode leftovers, etc.)
- Fixes for the network vector driver
- Fixes for time-travel mode

bitmap-for-6.12

Hi Linus,


 - switch all bitmamp APIs from inline to __always_inline, from Brian Norris;
 - introduce GENMASK_U128() macro, from Anshuman Khandual.

The __always_inline series improves on code generation, and now with
the latest compiler versions is required to avoid compilation
warnings. It spent enough in my backlog, and I'm thankful to Brian
Norris for taking over and moving it forward.

GENMASK_U128() is a prerequisite needed for arm64 development.

Thanks,
Yury

10, Some bug fixes and other small changes.

One bugfix patch, one preparation patch, and one conversion patch.

TOMOYO is useful as an analysis tool for learning how a Linux system works.
My boss was hoping that SELinux's policy is generated from what TOMOYO has
observed. A translated paper describing it is available at
https://master.dl.sourceforge.net/project/tomoyo/docs/nsf2003-en.pdf/nsf2003-en.pdf?viasf=1 .
Although that attempt failed due to mapping problem between inode and pathname,
TOMOYO remains as an access restriction tool due to ability to write custom
policy by individuals.

I was delivering pure LKM version of TOMOYO (named AKARI) to users who
cannot afford rebuilding their distro kernels with TOMOYO enabled. But
since the LSM framework was converted to static calls, it became more
difficult to deliver AKARI to such users. Therefore, I decided to update
TOMOYO so that people can use mostly LKM version of TOMOYO with minimal
burden for both distributors and users.

Please git pull the following tag:


xen: branch for v6.12-rc1a

It contains a second round of Xen related changes and features for the
6.12 merge window:

- A small fix of the xen-pciback driver for a warning issued by sparse

- A series of 3 patches supporting PCI passthrough when using a PVH
  dom0

- A series of 5 patches enabling to load the kernel in PVH mode at
  arbitrary addresses, avoiding conflicts with the memory map when
  running as a Xen dom0 using the host memory layout

Thanks.

Driver core update for 6.12-rc1

Here is a small set of patches for the driver core code for 6.12-rc1.

This set is the one that caused the most delay on my side, due to lots
of last-minute reports of problems in the async shutdown feature that
was added.  In the end, I've reverted all of the patches in that series
so we are back to "normal" and the patch set is being reworked for the
next merge window.

Other than the async shutdown patches that were reverted, included in
here are:
  - minor driver core cleanups
  - minor driver core bus and class api cleanups and simplifications for
    some callbacks
  - some const markings of structures
  - other even more minor cleanups

All of these, including the last minute reverts, have been in
linux-next, but all of the reports of problems in linux-next were before
the reverts happened.  After the reverts, all is good.

asm-generic updates for 6.12

These are only two small patches, one cleanup for arch/alpha
and a preparation patch cleaning up the handling of runtime
constants in the linker scripts.

It looks like that most people are still traveling: both the ML volume
and the processing capacity are low.

Including fixes from netfilter.

Previous releases - regressions:

  - netfilter:
    - nf_reject_ipv6: fix nf_reject_ip6_tcphdr_put()
    - nf_tables: keep deleted flowtable hooks until after RCU

  - tcp: check skb is non-NULL in tcp_rto_delta_us()

  - phy: aquantia: fix -ETIMEDOUT PHY probe failure when firmware not present

  - eth: virtio_net: fix mismatched buf address when unmapping for small packets

  - eth: stmmac: fix zero-division error when disabling tc cbs

  - eth: bonding: fix unnecessary warnings and logs from bond_xdp_get_xmit_slave()

Previous releases - always broken:

  - netfilter:
    - fix clash resolution for bidirectional flows
    - fix allocation with no memcg accounting

  - eth: r8169: add tally counter fields added with RTL8125

  - eth: ravb: fix rx and tx frame size limit

Char/Misc and other driver changes for 6.12-rc1

Here is the "big" set of char/misc and other driver subsystem changes
for 6.12-rc1.  Sorry for the delay, conference travel for the past two
weeks has this and my other pull requests showing up real late
in the cycle.

Lots of changes in here, primarily dominated by the usual IIO driver
updates and additions, but there are also small driver subsystem updates
all over the place.  Included in here are:
  - lots and lots of new IIO drivers and updates to existing ones
  - interconnect subsystem updates and new drivers
  - nvmem subsystem updates and new drivers
  - mhi driver updates
  - power supply subsystem updates
  - kobj_type const work for many different small subsystems
  - comedi driver fix
  - coresight subsystem and driver updates
  - fpga subsystem improvements
  - slimbus fixups
  - binder new feature addition for "frozen" notifications
  - lots and lots of other small driver updates and cleanups

All of these have been in linux-next for a long time with no reported
problems.

Staging driver updates for 6.12-rc1

Here is the big set of staging driver cleanups and removals for
6.12-rc1.

Nothing exciting here, just slow, constant, forward progress in removing
code and cleaning up some old drivers, along with removing one of them
that was not being used anymore at all.  In discussions with some
developers this past week, even more deletions will be happening for the
next major merge window, as we seems to have code here that obviously no
one is using anymore.

Along with the normal cleanups is the good vme_user code forward
progress, the one major bright spot in the staging subsystem for code
that people rely on, and is getting good development behind it.
Hopefully it can graduate out of staging "soon".

All of these changes have been in linux-next for a long time with no
reported problems.

TTY/Serial driver update for 6.12-rc1

Here is the "big" set of tty/serial driver updates for 6.12-rc1.

Nothing major in here, just nice forward progress in the slow cleanup of
the serial apis, and lots of other driver updates and fixes.

Included in here are:
  - serial api updates from Jiri to make things more uniform and sane
  - 8250_platform driver cleanups
  - samsung serial driver fixes and updates
  - qcom-geni serial driver fixes from Johan for the bizarre UART engine
    that that chip seems to have.  Hopefully it's in a better state now,
    but hardware designers still seem to come up with more ways to make
    broken UARTS 40+ years after this all should have finished.
  - sc16is7xx driver updates
  - omap 8250 driver updates
  - 8250_bcm2835aux driver updates
  - a few new serial driver bindings added
  - other serial minor driver updates

All of these have been in linux-next for a long time with no reported

Nothing "major" in here, except for a new 9p network gadget that has
been worked on for a long time (all of the needed acks are here.)  Other
than that, it's the usual set of:
  - Thunderbolt / USB4 driver updates and additions for new hardware
  - dwc3 driver updates and new features added
  - xhci driver updates
  - typec driver updates
  - USB gadget updates and api additions to make some gadgets more
    configurable by userspace

Probes updates for v6.12:

- uprobes: make trace_uprobe->nhit counter a per-CPU one
   This makes uprobe event's hit counter per-CPU for improving
   scalability on multi-core environment.

- kprobes: Remove obsoleted declaration for init_test_probes
   Remove unused init_test_probes() from header.

- Raw tracepoint probe supports raw tracepoint events on modules.
   The tracepoint events using fprobe were introduced in v6.5, but
   tracepoints can be compiled in modules. This supports such a case.
   This includes the following improvements.
  . tracepoint: add a function for iterating over all tracepoints in
    all modules.
  . tracepoint: Add a function for iterating over tracepoints in a
    module.
  . tracing/fprobe: Support raw tracepoint events on modules.
  . tracing/fprobe: Support raw tracepoints on future loaded modules.
     This allows user to add tracepoint events on modules which is
     not loaded yet.
  . selftests/tracing: Add a test for tracepoint events on modules.

clang-format changes for v6.12

A routine update of the 'for_each' macro list.

Here is the RTC subsystem pull request for 6.12. We get more conversions
of DT bindings to yaml. There is one new driver, for the DFRobot
SD2405AL and support for important features of the stm32 RTC.

RTC for 6.12

New driver:
 - DFRobot SD2405AL

Drivers:
 - stm32: add alarm A out and LSCO support
 - sun6i: disable automatic clock input switching
 - m48t59: set range

This is the next round of the Rust support.

Quite late, but all the commits have been in linux-next for at least a
week (most have been for a few weeks).

This PR is a bit more involved than the usual ones -- the relevant
maintainers were OK with us carrying the patches since there were a few
interdependencies.

Three simple conflicts expected. Please note that akpm and I carried
the same patch ("kasan: simplify and clarify Makefile").

Regarding Rust-related things: you already merged the QR code panic
screen via DRM, the Applied Micro QT2025 PHY driver (with a new `sizes`
module) via netdev, a `k{v,}realloc()` patch via mm and two selftest
config fixes. You have also got a firmware code doc fix via asoc.

Rust changes for v6.12

Toolchain and infrastructure:

 - Support 'MITIGATION_{RETHUNK,RETPOLINE,SLS}' (which cleans up objtool
   warnings), teach objtool about 'noreturn' Rust symbols and mimic
   '___ADDRESSABLE()' for 'module_{init,exit}'. With that, we should be
   objtool-warning-free, so enable it to run for all Rust object files.

 - KASAN (no 'SW_TAGS'), KCFI and shadow call sanitizer support.

 - Support 'RUSTC_VERSION', including re-config and re-build on change.

 - Split helpers file into several files in a folder, to avoid conflicts
   in it. Eventually those files will be moved to the right places with
   the new build system. In addition, remove the need to manually export
   the symbols defined there, reusing existing machinery for that.

 - Relax restriction on configurations with Rust + GCC plugins to just
   the RANDSTRUCT plugin.

'kernel' crate:

 - New 'list' module: doubly-linked linked list for use with reference
   counted values, which is heavily used by the upcoming Rust Binder.
   This includes 'ListArc' (a wrapper around 'Arc' that is guaranteed
   unique for the given ID), 'AtomicTracker' (tracks whether a 'ListArc'
   exists using an atomic), 'ListLinks' (the prev/next pointers for an
   item in a linked list), 'List' (the linked list itself), 'Iter' (an
   iterator over a 'List'), 'Cursor' (a cursor into a 'List' that allows
   to remove elements), 'ListArcField' (a field exclusively owned by a
   'ListArc'), as well as support for heterogeneous lists.

 - New 'rbtree' module: red-black tree abstractions used by the upcoming
   Rust Binder. This includes 'RBTree' (the red-black tree itself),
   'RBTreeNode' (a node), 'RBTreeNodeReservation' (a memory reservation
   for a node), 'Iter' and 'IterMut' (immutable and mutable iterators),
   'Cursor' (bidirectional cursor that allows to remove elements), as
   well as an entry API similar to the Rust standard library one.

 - 'init' module: add 'write_[pin_]init' methods and the 'InPlaceWrite'
   trait. Add the 'assert_pinned!' macro.

 - 'sync' module: implement the 'InPlaceInit' trait for 'Arc' by
   introducing an associated type in the trait.

 - 'alloc' module: add 'drop_contents' method to 'BoxExt'.

 - 'types' module: implement the 'ForeignOwnable' trait for
   'Pin<Box<T>>' and improve the trait's documentation. In addition,
   add the 'into_raw' method to the 'ARef' type.

 - 'error' module: in preparation for the upcoming Rust support for
   32-bit architectures, like arm, locally allow Clippy lint for those.

Documentation:

 - https://rust.docs.kernel.org has been announced, so link to it.

 - Enable rustdoc's "jump to definition" feature, making its output a
   bit closer to the experience in a cross-referencer.

 - Debian Testing now also provides recent Rust releases (outside of
   the freeze period), so add it to the list.

MAINTAINERS:

 - Trevor is joining as reviewer of the "RUST" entry.

And a few other small bits.

tags/fuse-update-6.12

- Add support for idmapped fuse mounts (Alexander Mikhalitsyn).  This
touches some non-fuse files, these have been reviewed by Christian.

- Add optimization when checking for writeback (yangyun).

- Add tracepoints (Josef Bacik).

- Clean up writeback code (Joanne Koong).

- Clean up request queuing (me).

- Misc fixes.

  to simplify releasing of resources (with more drivers to follow)

- evdev will limit amount of data that can be written into an evdev
  instance at a given time to 4096 bytes (170 input events) to avoid
  holding evdev->mutex for too long and starving other users

- Spitz has been converted to use software nodes/properties to describe
  its matrix keypad and GPIO-connected LEDs

VFIO updates for v6.12

 - Remove several unused structure and function declarations, and unused
   variables. (Dr. David Alan Gilbert, Yue Haibing, Zhang Zekun)

 - Constify unmodified structure in mdev. (Hongbo Li)

hwspinlock update for v6.12

This converts the Spreadtrum hardware spinlock DeviceTree binding to
YAML, to allow validation of related DeviceTree source.

rpmsg updates for v6.12

This performs minor cleanup/refactor of the Qualcomm GLINK code, in
order to then add trace events related to the messages exchange with the
remote side, useful for debugging a range of interoperability issues.

The nested structs with flexible array members, in the same driver, is
then rewritten to avoid the risk of invalid accesses.

remoteproc updates for v6.12

This adds remoteproc support for the Cortex M4F found in AM62x and AM64x
of the TI K3 family, support for the modem remoteproc in the Qualcomm
SDX75, and audio, compute and general-purpose DSPs of the Qualcomm
SA8775P.

The i.MX remoteproc driver gains support for blocking and non-blocking
mailbox transmissions, followed by the implementation of poweroff and
reboot mechanisms, using the same. This is followed by a few bug fixes
and minor improvements.

A few cleanups and bug fixes for the TI K3 DSP and R5F drivers are
introduced.

Support for mapping SRAM regions into the AMD-Xilinx Zynqmp R5 cores is
added.

The Ingenic, TI DA8xx, TI Keystone, TI K3, ST slim drivers are
simplified using devres helpers for various allocations.

Uses of of_{find,get}_property() are replaced with of_property_present()
where possible.

Only a single change, cleaning up white space in debug message.

Regards
Greg

 - svc: adjust rates, fix race condition

This PR brings signal and abstract UNIX socket control to Landlock, contributed
by Tahera Fahimi during her Outreachy internship [1].  These features are
useful to better isolate processes.

master branch.  The kernel code has been tested in the latest linux-next
releases for a few weeks, but I rebased it on your master branch last week
because of VFS and LSM tree dependencies.

We can now scope a Landlock domain thanks to a new "scoped" field that can deny
interactions with resources outside of this domain.  The
LANDLOCK_SCOPE_ABSTRACT_UNIX_SOCKET flag denies connections to an abstract UNIX
socket created outside of the current scoped domain [2], and the
LANDLOCK_SCOPE_SIGNAL flag denies sending a signal to processes outside of the
current scoped domain [3].  These restrictions also apply to nested domains
according to their scope.  The related changes will also be useful to support
other kind of IPC isolations.

Test coverage for security/landlock is 92.2% of 1046 lines according to
gcc/gcov-14, and it was 91.7% of 961 lines before this series.

because their defect rate was not going down as fast as I would like
prior to -rc1, especially considering maintainer travel plans. Those
changes will be rescheduled for v6.13.

The commits included here have been in linux-next for weeks and pass

NFSD 6.12 Release Notes

Notable features of this release include:

- Pre-requisites for automatically determining the RPC server thread
  count
- Clean-up and preparation for supporting LOCALIO, which will be
  merged via the NFS client tree
- Enhancements and fixes to NFSv4.2 COPY offload
- A new Python-based tool for generating kernel SunRPC XDR encoding
  and decoding functions, added as an aid for prototyping features
  in protocols based on the Linux kernel's SunRPC implementation.

As always I am grateful to the NFSD contributors, reviewers,
testers, and bug reporters who participated during this cycle.

One bugfix and one non-code change for this PR; did not get things into
linux-next on time for proper testing because my PTO ended way to late in the
cycle. I expect the next cycle to be busier as I move through the backlog. I'll
be sure to use the co-maintainers to avoid having this situation next time.

Summary

* Bug fix: Avoid evaluating non-mount ctl_tables as a sysctl_mount_point by
  removing the unlikely (but possible) chance that the permanently empty
  ctl_table array shares its address with another ctl_table.
* Update Joel Granados' contact info in MAINTAINERS.

Testing

* Bug fix merged to linux-next after 6.11-rc5

Hi,

a few more patches that I'd still like to get merged before rc1 as they
are fixes for user reported bugs.


- fix dangling pointer to rb-tree of defragmented inodes after cleanup

- a followup fix to handle concurrent lseek on the same fd that could
  leak memory under some conditions

- fix wrong root id reported in tree checker when verifying dref

dia/v6.12-1

For:

- New CEC driver: Extron DA HD 4K Plus;
- Lots of driver fixes, cleanups and improvements.

ring-buffer: Updates for v6.12:

- Merged v6.11-rc3 into trace/ring-buffer/core

  The v6.11 ring buffer pull request was not made due to Mathieu Desnoyers
  making a comment to the pull request. Mathieu and I resolved it on IRC,
  but we did not let Linus know that it was resolved. Linus did not do the
  pull thinking it still had some unresolved issues.

  The ring buffer work for 6.12 was dependent on both this pull request as
  well as the reserve_mem kernel command line option that was going upstream
  through the memory management tree. The ring buffer repo was being used by
  others so it could not be rebased. In order to continue the work, the
  v6.11-rc3 branch was pulled in to get access to the reserve_mem work.

This has the 6.11 pull request that did not make it into 6.11, which was:

  tracing/ring-buffer: Have persistent buffer across reboots

  This allows for the tracing instance ring buffer to stay persistent across
  reboots. The way this is done is by adding to the kernel command line:

    trace_instance=boot_map@0x285400000:12M

  This will reserve 12 megabytes at the address 0x285400000, and then map
  the tracing instance "boot_map" ring buffer to that memory. This will
  appear as a normal instance in the tracefs system:

    /sys/kernel/tracing/instances/boot_map

  A user could enable tracing in that instance, and on reboot or kernel
  crash, if the memory is not wiped by the firmware, it will recreate the
  trace in that instance. For example, if one was debugging a shutdown of a
  kernel reboot:

   # cd /sys/kernel/tracing
   # echo function > instances/boot_map/current_tracer
   # reboot
  [..]
   # cd /sys/kernel/tracing
   # tail instances/boot_map/trace

  On reboot, the buffer is examined to make sure it is valid. The validation
  check even steps through every event to make sure the meta data of the
  event is correct. If any test fails, it will simply reset the buffer, and
  the buffer will be empty on boot.

The new changes for 6.12 are:

- Allow the tracing persistent boot buffer to use the "reserve_mem" option

  Instead of having the admin find a physical address to store the persistent
  buffer, which can be very tedious if they have to administrate several
  different machines, allow them to use the "reserve_mem" option that will
  find a location for them. It is not as reliable because of KASLR, as the
  loading of the kernel in different locations can cause the memory
  allocated to be inconsistent. Booting with "nokaslr" can make reserve_mem
  more reliable.

- Have function graph tracer handle offsets from a previous boot.

  The ring buffer output from a previous boot may have different addresses
  due to kaslr. Have the function graph tracer handle these by using the
  delta from the previous boot to the new boot address space.

- Only reset the saved meta offset when the buffer is started or reset

  In the persistent memory meta data, it holds the previous address space
  information, so that it can calculate the delta to have function tracing
  work. But this gets updated after being read to hold the new address
  space. But if the buffer isn't used for that boot, on reboot, the delta is
  now calculated from the previous boot and not the boot that holds the data
  in the ring buffer. This causes the functions not to be shown. Do not save
  the address space information of the current kernel until it is being
  recorded.

- Add a magic variable to test the valid meta data

  Add a magic variable in the meta data that can also be used for
  validation. The validator of the previous buffer doesn't need this magic
  data, but it can be used if the meta data is changed by a new kernel, which
  may have the same format that passes the validator but is used
  differently. This magic number can also be used as a "versioning" of the
  meta data.

- Align user space mapped ring buffer sub buffers to improve TLB entries

  Linus mentioned that the mapped ring buffer sub buffers were misaligned
  between the meta page and the sub-buffers, so that if the sub-buffers were
  bigger than PAGE_SIZE, it wouldn't allow the TLB to use bigger entries.

- Add new kernel command line "traceoff" to disable tracing on boot for instances

  If tracing is enabled for a boot instance, there needs a way to be able to
  disable it on boot so that new events do not get entered into the ring
  buffer and be mixed with events from a previous boot, as that can be
  confusing.

- Allow trace_printk() to go to other instances

  Currently, trace_printk() can only go to the top level instance. When
  debugging with a persistent buffer, it is really useful to be able to add
  trace_printk() to go to that buffer, so that you have access to them after
  a crash.

- Do not use "bin_printk()" for traces to a boot instance

  The bin_printk() saves only a pointer to the printk format in the ring
  buffer, as the reader of the buffer can still have access to it. But this
  is not the case if the buffer is from a previous boot. If the
  trace_printk() is going to a "persistent" buffer, it will use the slower
  version that writes the printk format into the buffer.

- Add command line option to allow trace_printk() to go to an instance

  Allow the kernel command line to define which instance the trace_printk()
  goes to, instead of forcing the admin to set it for every boot via the
  tracefs options.

- Start a document that explains how to use tracefs to debug the kernel

- Add some more kernel selftests to test user mapped ring buffer




trace-ring-buffer-v6.12

ktest.pl updates for 6.12:

- Add notification of build warnings for all tests

  Currently, the build will only fail on warnings if the ktest config file
  states that it should fail or if the compile is done with -Werror. This
  has allowed warnings to sneak in if it doesn't fail. Add a notification at
  the end of the test that will state that warnings were found in the build
  so that the developer will be aware of it.

- Fix the grub2 parser to not return the wrong kernel index

  ktest.pl can read the grub.cfg file to know what kernel to boot to via
  grub-reboot. This requires knowing the index that the kernel is referenced
  by in the grub.cfg file. Some distros have logic to determine the
  menuentry that can cause the ktest.pl to come up with the wrong index and
  boot the wrong kernel.




ktest-v6.12

this is the bulk of pin control changes for v6.12, not a lot this time
but the Sophgo SoC is a bit interesting RISC-V thing for image analysis,
and the Mobil EyeQ5 automotive SoC is interesting because it is *new*
MIPS stuff.

Details are in the signed tag.

I managed to pull some Intel ACPI ID patch into the devel branch first
and then sent the same as fix, so it appears in the diffstat but the
commit IDs should be the same and resolve just fine.


Yours,
Linus Walleij

This is the bulk of pin control changes for the v6.12 kernel cycle:

Core changes:

- Add support for "input-schmitt-microvolt" property, as used in the
  Sophgo SoC.

New drivers:

- Mobileye EyeQ5 pin controller, I think this is an automotive SoC.

- Rockchip rk3576 pin control support.

- Sophgo CV1800 series pin controllers: CV1800B, CV1812H and SG2000.

Improvements:

- Gradual improvements to Renesas, Samsung, Qualcomm, Nuvoton
  and a few other drivers.

Relatively quiet cycle here - which is good, because 6.11 was huge.

I think we'll be able to take off EXPERIMENTAL in inside of a year, see
below for more.

Cheers,
Kent

bcachefs changes for 6.12-rc1

rcu_pending, btree key cache rework: this solves lock contenting in the
key cache, eliminating the biggest source of the srcu lock hold time
warnings, and drastically improving performance on some metadata heavy
workloads - on multithreaded creates we're now 3-4x faster than xfs.

We're now using an rhashtable instead of the system inode hash table;
this is another significant performance improvement on multithreaded
metadata workloads, eliminating more lock contention.

for_each_btree_key_in_subvolume_upto(): new helper for iterating over
keys within a specific subvolume, eliminating a lot of open coded
"subvolume_get_snapshot()" and also fixing another source of srcu lock
time warnings, by running each loop iteration in its own transaction (as
the existing for_each_btree_key() does).

More work on btree_trans locking asserts; we now assert that we don't
hold btree node locks when trans->locked is false, which is important
because we don't use lockdep for tracking individual btree node locks.

Some cleanups and improvements in the bset.c btree node lookup code,
from Alan.

Rework of btree node pinning, which we use in backpointers fsck. The old
hacky implementation, where the shrinker just skipped over nodes in the
pinned range, was causing OOMs; instead we now use another shrinker with
a much higher seeks number for pinned nodes.

Rebalance now uses BCH_WRITE_ONLY_SPECIFIED_DEVS; this fixes an issue
where rebalance would sometimes fall back to allocating from the full
filesystem, which is not what we want when it's trying to move data to a
specific target.

Use __GFP_ACCOUNT, GFP_RECLAIMABLE for btree node, key cache
allocations.

Idmap mounts are now supported - Hongbo.

Rename whiteouts are now supported - Hongbo.

Erasure coding can now handle devices being marked as failed, or
forcibly removed. We still need the evacuate path for erasure coding,
but it's getting very close to ready for people to start using.

Status, and when will we be taking off experimental:

thanks.

"scripts/decode_stacktrace.sh: improve error reporting and usability" from
Luca Ceresoli does those things.

This updates includes a significant change to the processing context for
isochronous packets. Hopefully, many developers will test it before the
official release.

I hope you have a pleasant trip ;)


firewire updates for v6.12

The batch of changes includes the followwing:

- Replacing tasklet with usual workqueue for isochronous context
- Replacing IDR with XArray
- Utilizing guard macro where possible
- Printing deprecation warning when enabling debug parameter of
  firewire-ohci module

Additionally, it includes a single patch for sound subsystem which the
subsystem maintainer acked:

- Switching to nonatomic PCM operation

In FireWire subsystem, tasklet has been used as the bottom half of 1394
OHCi hardIRQ so long. In the recent kernel updates, BH workqueue has
been available, and some developers have proposed replacing tasklet with
BH workqueue. While it is fortunate that developers are still considering
the legacy subsystem, a simple replacement is not necessarily suitable.

As a first step towards dropping tasklet, I've investigated the
feasibility for 1394 OHCI isochronous context, and concluded that usual
workqueue is available. In the context, the batch of packets is processed
in the specific queue, thus the timing jitter caused by task scheduling is
not so critical. Additionally, DMA transmission can be scheduled
per-packet basis, therefore the context can be sleep between the operation
of transmissions. Furthermore, in-kernel protocol implementation involves
some CPU-bound tasks, which can sometimes consumes CPU time so long. These
characteristics suggest that usual workqueue is suitable, through BH
workqueues are not.

The replacement with usual workqueue allows unit drivers to process the
content of packets in non-atomic context. It brings some reliefs to some
drivers in sound subsystem that spin-lock is not mandatory anymore during
isochronous packet processing.

Enable PREEMPT_RT on supported architectures:

  After twenty years of development we finally reached the point to enable
  PREEMPT_RT support in the mainline kernel.

  All prerequisites are merged, so enable it on the supported architectures
  ARM64, RISCV and X86(32/64-bit).

Thanks,

tglx

Enumeration:

  - Wait for device readiness after reset by polling Vendor ID and looking
    for Configuration RRS instead of polling the Command register and
    looking for non-error completions, to avoid hardware retries done for
    RRS on non-Vendor ID reads (Bjorn Helgaas)

  - Rename CRS Completion Status to RRS ('Request Retry Status') to match
    PCIe r6.0 spec usage (Bjorn Helgaas)

  - Clear LBMS bit after a manual link retrain so we don't try to retrain a
    link when there's no downstream device anymore (Maciej W. Rozycki)

  - Revert to the original link speed after retraining fails instead of
    leaving it restricted to 2.5GT/s, so a future device has a chance to
    use higher speeds (Maciej W. Rozycki)

  - Wait for each level of downstream bus, not just the first, to become
    accessible before restoring devices on that bus (Ilpo Jц╓rvinen)

  - Add ARCH_PCI_DEV_GROUPS so s390 can add its own attribute_groups
    without having to stomp on the core's pdev->dev.groups (Lukas Wunner)

Driver binding:

perf tools improvements and fixes for v6.12:

- Use BPF + BTF to collect and pretty print syscall and tracepoint arguments in
  'perf trace', done as an GSoC activity.

- Data-type profiling improvements:

  - Cache debuginfo to speed up data type resolution.

  - Add the 'typecln' sort order, to show which cacheline in a target is hot or
    cold. The following shows members in the cfs_rq's first cache line:

      $ perf report -s type,typecln,typeoff -H
      ...
      -    2.67%        struct cfs_rq
         +    1.23%        struct cfs_rq: cache-line 2
         +    0.57%        struct cfs_rq: cache-line 4
         +    0.46%        struct cfs_rq: cache-line 6
         -    0.41%        struct cfs_rq: cache-line 0
                 0.39%        struct cfs_rq +0x14 (h_nr_running)
                 0.02%        struct cfs_rq +0x38 (tasks_timeline.rb_leftmost)

  - When a typedef resolves to a unnamed struct, use the typedef name.

  - When a struct has just one basic type field (int, etc), resolve the type
    sort order to the name of the struct, not the type of the field.

  - Support type folding/unfolding in the data-type annotation TUI.

  - Fix bitfields offsets and sizes.

  - Initial support for PowerPC, using libcapstone and the usual objdump
    disassembly parsing routines.

- Add support for disassembling and addr2line using the LLVM libraries,
  speeding up those operations.

- Support --addr2line option in 'perf script' as with other tools.

- Intel branch counters (LBR event logging) support, only available in recent
  Intel processors, for instance, the new "brcntr" field can be asked from
  'perf script' to print the information collected from this feature:

  $ perf script -F +brstackinsn,+brcntr

  # Branch counter abbr list:
  # branch-instructions:ppp = A
  # branch-misses = B
  # '-' No event occurs
  # '+' Event occurrences may be lost due to branch counter saturated

- Support Timed PEBS (Precise Event-Based Sampling), a recent hardware feature
  in Intel processors.

- Add 'perf ftrace profile' subcommand, using ftrace's function-graph tracer so
  that users can see the total, average, max execution time as well as the
  number of invocations easily, for instance:

  $ sudo perf ftrace profile -G __x64_sys_perf_event_open -- \
    perf stat -e cycles -C1 true 2> /dev/null | head

In the v6.12 scheduler development cycle we had 63 commits from 18 contributors:

 - Implement the SCHED_DEADLINE server infrastructure - Daniel Bristot de Oliveira's
   last major contribution to the kernel:

     "SCHED_DEADLINE servers can help fixing starvation issues of low priority
     tasks (e.g., SCHED_OTHER) when higher priority tasks monopolize CPU
     cycles. Today we have RT Throttling; DEADLINE servers should be able to
     replace and improve that."

     (Daniel Bristot de Oliveira, Peter Zijlstra, Joel Fernandes,
      Youssef Esmat, Huang Shijie)

 - Preparatory changes for sched_ext integration:

     - Use set_next_task(.first) where required
     - Fix up set_next_task() implementations
     - Clean up DL server vs. core sched
     - Split up put_prev_task_balance()
     - Rework pick_next_task()
     - Combine the last put_prev_task() and the first set_next_task()
     - Rework dl_server
     - Add put_prev_task(.next)

      (Peter Zijlstra, with a fix by Tejun Heo)

 - Complete the EEVDF transition and refine EEVDF scheduling:

     - Implement delayed dequeue
     - Allow shorter slices to wakeup-preempt
     - Use sched_attr::sched_runtime to set request/slice suggestion
     - Document the new feature flags
     - Remove unused and duplicate-functionality fields
     - Simplify & unify pick_next_task_fair()
     - Misc debuggability enhancements

      (Peter Zijlstra, with fixes/cleanups by Dietmar Eggemann,
       Valentin Schneider and Chuyi Zhou)

 - Initialize the vruntime of a new task when it is first enqueued,
   resulting in significant decrease in latency of newly woken tasks.
   (Zhang Qiao)

 - Introduce SM_IDLE and an idle re-entry fast-path in __schedule()
   (K Prateek Nayak, Peter Zijlstra)

 - Clean up and clarify the usage of Clean up usage of rt_task()
   (Qais Yousef)

 - Preempt SCHED_IDLE entities in strict cgroup hierarchies
   (Tianchen Ding)

 - Clarify the documentation of time units for deadline scheduler
   parameters. (Christian Loehle)

 - Remove the HZ_BW chicken-bit feature flag introduced a year ago,
   the original change seems to be working fine.
   (Phil Auld)

 - Misc fixes and cleanups (Chen Yu, Dan Carpenter, Huang Shijie,
   Peilin He, Qais Yousefm and Vincent Guittot)

dma-mapping updates for linux 6.12

 - support DMA zones for arm64 systems where memory starts at > 4GB
   (Baruch Siach, Catalin Marinas)
 - support direct calls into dma-iommu and thus obsolete dma_map_ops for
   many common configurations (Leon Romanovsky)
 - add DMA-API tracing (Sean Anderson)
 - remove the not very useful return value from various dma_set_* APIs
   (Christoph Hellwig)
 - misc cleanups and minor optimizations (Chen Y, Yosry Ahmed,
   Christoph Hellwig)

This is the main drm pull request for 6.12-rc1.

There are some minor conflicts with your tree but none seemed too
difficult to solve, let me know if there is any problems on your end.

This adds a couple of patches outside the drm core, all should be
acked appropriately, the string and pstore ones are the main ones that
come to mind.

Otherwise it's the usual drivers, xe is getting enabled by default on
some new hardware, we've changed the device number handling to allow
more devices, and we added some optional rust code to create QR codes
in the panic handler, an idea first suggested I think 10 years ago :-)

Fuller summary below,
Thanks,
Dave.

Performance events changes for v6.12:

 - Implement per-PMU context rescheduling to significantly improve single-PMU
   performance, and related cleanups/fixes. (by Peter Zijlstra and Namhyung Kim)

 - Fix ancient bug resulting in a lot of events being dropped erroneously
   at higher sampling frequencies. (by Luo Gengkun)

 - uprobes enhancements:

     - Implement RCU-protected hot path optimizations for better performance:

         "For baseline vs SRCU, peak througput increased from 3.7 M/s (million uprobe
          triggerings per second) up to about 8 M/s. For uretprobes it's a bit more
          modest with bump from 2.4 M/s to 5 M/s.

          For SRCU vs RCU Tasks Trace, peak throughput for uprobes increases further from
          8 M/s to 10.3 M/s (+28%!), and for uretprobes from 5.3 M/s to 5.8 M/s (+11%),
          as we have more work to do on uretprobes side.

          Even single-thread (no contention) performance is slightly better: 3.276 M/s to
          3.396 M/s (+3.5%) for uprobes, and 2.055 M/s to 2.174 M/s (+5.8%)
          for uretprobes."

          (by Andrii Nakryiko et al)

     - Document mmap_lock, don't abuse get_user_pages_remote(). (by Oleg Nesterov)

     - Cleanups & fixes to prepare for future work:

        - Remove uprobe_register_refctr()
- Simplify error handling for alloc_uprobe()
        - Make uprobe_register() return struct uprobe *
        - Fold __uprobe_unregister() into uprobe_unregister()
        - Shift put_uprobe() from delete_uprobe() to uprobe_unregister()
        - BPF: Fix use-after-free in bpf_uprobe_multi_link_attach()

          (by Oleg Nesterov)

 - New feature & ABI extension: allow events to use PERF_SAMPLE READ with
   inheritance, enabling sample based profiling of a group of counters over
   a hierarchy of processes or threads.  (by Ben Gainey)

 - Intel uncore & power events updates:

      - Add Arrow Lake and Lunar Lake support
      - Add PERF_EV_CAP_READ_SCOPE
      - Clean up and enhance cpumask and hotplug support

        (by Kan Liang)

      - Add LNL uncore iMC freerunning support
      - Use D0:F0 as a default device

        (by Zhenyu Wang)

 - Intel PT: fix AUX snapshot handling race. (by Adrian Hunter)

 - Misc fixes and cleanups. (by James Clark, Jiri Olsa, Oleg Nesterov and Peter Zijlstra)

Thanks,

Ingo

Summary:

- Remove some unnecesary hold/unhold rsb refcounting
  in cases where an existing refcount is known to exist.
- Remove some unnecessary checking for zero nodeids, which
  should never exist, and add some warning if they do.
- Make the slow freeing of structs in release_lockspace()
  async, run from a workqueue.
- Prior rcu freeing allows some further struct lookups to
  run without a lock.
- Use blocking kernel_connect on sockets to avoid EINPROGRESS.

Thanks,
Dave

lkmm: Add documentation and mailing list

This pull request contains documentation updates from Andrea Parri and
Akira Yokosawa.  Also, there is now an lkmm@lists.linux.dev, and Boqun
Feng's update adds this to the LKMM MAINTAINERS entry.

Not included in this pull request are a couple of more commits from
Puranjay Mohan adding more atomic operations to LKMM, but these await a
herdtools7 release that includes tool-side support for this functionality.
With luck, I will send a separate pull request for these later in the
merge window.

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>


There's one change adding support for a new PMU model and another adding
documentation for the subsystem which probably should have been part of
the initial commit but better late than never.

Details are in the signed tag.

Thanks,
Bartosz Golaszewski

power sequencing updates for v6.12-rc1

- add support for the new PMU variant inside the WCN6855 chipset
- add documentation for the subsystem

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>


Here are the updates from the GPIO tree for the next release. We have one
new driver, some improvements to core GPIO code, various changes in
drivers and their DT bindings as well fixes to kerneldocs.

Overall it has been a slow cycle, most likely due to the summertime
vacation period and the changelog reflects it.

The merge from the MFD tree is there to pull dependencies for the new
driver.

There is a trivial conflict with the SoC tree (just drop
arch/arm/mach-ep93xx/vision_ep9307.c).

gpio updates for v6.12-rc1

Core GPIOLIB:
- provide and add users for a macro allowing to iterate over accepted
  GPIO property names of consumer device nodes
- remove legacy definitions that are no longer used
- put legacy GPIO devres helpers together with the rest of the deprecated
  code
- implement and use swnode_gpio_get_reference(): a wrapper simplifying
  the underlying calls to fwnode_property_get_reference_args()
- use IS_ERR_OR_NULL() where it makes sense
- replace of_find_property() with of_property_present()
- simplify code with the scoped variant of OF-node children iterator

Documentation:
- update GPIO kerneldocs with Return sections
- fix "Excess struct member description" warnings now being triggered

please pull the latest x86/apic branch from:

Updates for the x86 APIC code:

  - Handle an allocation failure in the IO/APIC code gracefully instead of
    crashing the machine.

  - Remove support for APIC local destination mode on 64bit

    Logical destination mode of the local APIC is used for systems with up
    to 8 CPUs. It has an advantage over physical destination mode as it
    allows to target multiple CPUs at once with IPIs. That advantage was
    definitely worth it when systems with up to 8 CPUs were state of the
    art for servers and workstations, but that's history.

    In the recent past there were quite some reports of new laptops failing
    to boot with logical destination mode, but they work fine with physical
    destination mode. That's not a suprise because physical destination
    mode is guaranteed to work as it's the only way to get a CPU up and
    running via the INIT/INIT/STARTUP sequence. Some of the affected
    systems were cured by BIOS updates, but not all OEMs provide them.

    As the number of CPUs keep increasing, logical destination mode becomes
    less used and the benefit for small systems, like laptops, is not
    really worth the trouble. So just remove logical destination mode
    support for 64bit and be done with it.

  - Code and comment cleanups in the APIC area.

please pull the latest x86/mm branch from:



Updates for x86 memory management:

 - Make LAM enablement safe vs. kernel threads using a process mm
   temporarily as switching back to the process would not update CR3 and
   therefore not enable LAM causing faults in user space when using tagged
   pointers. Cure it by synchronizing LAM enablement via IPIs to all CPUs
   which use the related mm.

 - Cure a LAM harmless inconsistency between CR3 and the state during
   context switch. It's both confusing and prone to lead to real bugs

 - Handle alt stack handling for threads which run with a non-zero
   protection key. The non-zero key prevents the kernel to access the
   alternate stack. Cure it by temporarily enabling all protection keys for
   the alternate stack setup/restore operations.

 - Provide a EFI config table identity mapping for kexec kernel to prevent
   kexec fails because the new kernel cannot access the config table array

 - Use GB pages only when a full GB is mapped in the identity map as
   otherwise the CPU can speculate into reserved areas after the end of
   memory which causes malfunction on UV systems.

 - Remove the noisy and pointless SRAT table dump during boot

 - Use is_ioremap_addr() for iounmap() address range checks instead of
   high_memory. is_ioremap_addr() is more precise.

Updates for x86 timers:

  - Use the topology information of number of packages for making the
    decision about TSC trust instead of using the number of online nodes
    which is not reflecting the real topology.

  - Stop the PIT timer 0 when its not in use as to stop pointless emulation
    in the VMM.

  - Fix the PIT timer stop sequence for timer 0 so it truly stops both real
    hardware and buggy VMM emulations.

Updates for x86 FRED:

  - Enable FRED right after init_mem_mapping() because at that point the
    early IDT fault handler is replaced by the real fault handler. The real
    fault handler retrieves the faulting address from the stack frame and
    not from CR2 when the FRED feature is set. But that obviously only
    works when FRED is enabled in the CPU as well.

  - Set SS to __KERNEL_DS when enabling FRED to prevent a corner case where
    ERETS can observe a SS mismatch and raises a #GP.

pwm: Changes for v6.12-rc1

This pull request contains some cleanups to the core and some mostly
minor updates to a bunch of drivers and device tree bindings. One thing
worth pointing out is that it contains an immutable branch containing
support for a new mfd chip (Analog Devices ADP5585) with several sub
drivers. So expect to get the four affected commits also from my fellow
MFD and GPIO maintainers.

Thanks go to Andrew Kreimer, Clark Wang, Conor Dooley, David Lechner,
Dmitry Rokosov, Frank Li, Geert Uytterhoeven, George Stark, Jiapeng
Chong, Krzysztof Kozlowski, Laurent Pinchart, Liao Chen, Liu Ying, Rob
Herring and Wolfram Sang for code contributions and reviews and to Lee
Jones for preparing the above mentioned immutable branch.

Another relatively mundane cycle for docs:

- The beginning of an EEVDF scheduler document

- More Chinese translations

- A rethrashing of our bisection documentation

...plus the usual array of smaller fixes, and more than the usual number of
typo fixes.

Originally I'd planned on sending each of the vDSO getrandom() architecture
ports to their respective arch trees. But as we started to work on this, we
found lots of interesting issues in the shared code and infrastructure, the
fixes for which the various archs needed to base their work. So in the end,
this turned into a nice collaborative effort fixing up issues and porting to
5 new architectures -- arm64, powerpc64, powerpc32, s390x, and loongarch64 --
with everybody pitching in and commenting on each other's code. It was a fun
development cycle.

This pull request contains:

- Numerous fixups to the vDSO selftest infrastructure, getting it running
  successfully on more platforms, and fixing bugs in it.

- Additions to the vDSO getrandom & chacha selftests. Basically every time
  manual review unearthed a bug in a revision of an arch patch, or an
  ambiguity, the tests were augmented. By the time the last arch was submitted
  for review, s390x, v1 of the series was essentially fine right out of the
  gate.

- Fixes to the the generic C implementation of vDSO getrandom, to build and
  run successfully on all archs, decoupling it from assumptions we had
  (unintentionally) made on x86_64 that didn't carry through to the other
  architectures.

- Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by Huacai
  Chen.

- Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked by Will
  Deacon.

- Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit varieties, from
  Christophe Leroy and acked by Michael Ellerman.

- Port of vDSO getrandom to S390X from Heiko Carstens, the arch maintainer.

While it'd be natural for there to be things to fix up over the course of the
6.12 cycle, these patches got a decent amount of review from a fairly diverse
crew of folks on the mailing lists, and, for the most part, they've been
cooking in linux-next, which has been helpful for ironing out build issues.

In terms of architectures, I think that mostly takes care of the important
64-bit archs with hardware still being produced and running production loads
in settings where vDSO getrandom is likely to help. Arguably there's still
RISC-V left, and we'll see for 6.13 whether they find it useful and submit a
port.

I haven't seen any merge conflicts from Stephen with linux-next. But this pull
does touch lots of different archs, so I was thinking it'd probably make sense
to merge this early in the cycle, before merging the architectures pulls from
the various archs. But you know best there, of course.

On a more personal note, sorry I'm unable to make it to Vienna this year; it
would have been nice to talk about things face to face. We'll see about next
year.


Thanks,
Jason

Updates for the interrupt subsystem:

- Remove a global lock in the affinity setting code

  The lock protects a cpumask for intermediate results and the lock
  causes a bottleneck on simultaneous start of multiple virtual

  cpumask which is nicely serialized by raw spinlock held when
  executing this code.

- Provide support for giving a suffix to interrupt domain names.

  That's required to support devices with subfunctions so that the
  domain names are distinct even if they originate from the same
  device node.

- The usual set of cleanups and enhancements all over the place

Updates for timers and timekeeping:

  - Core:

- Overhaul of posix-timers in preparation of removing the
  workaround for periodic timers which have signal delivery
  ignored.

        - Remove the historical extra jiffie in msleep()

  msleep() adds an extra jiffie to the timeout value to ensure
  minimal sleep time. The timer wheel ensures minimal sleep
  time since the large rewrite to a non-cascading wheel, but the
  extra jiffie in msleep() remained unnoticed. Remove it.

        - Make the timer slack handling correct for realtime tasks.

  The procfs interface is inconsistent and does neither reflect
  reality nor conforms to the man page. Show the correct 0 slack
  for real time tasks and enforce it at the core level instead of
  having inconsistent individual checks in various timer setup
  functions.

        - The usual set of updates and enhancements all over the place.

pstore updates for v6.12-rc1

- ramoops: Fix .rst typo (Steven Rostedt)

- pstore: replace spinlock_t by raw_spinlock_t (Wen Yang)

spi: Updates for v6.12

This is quite a quiet release for sPI.  The one new core feature here is
support for configuring the state of the MOSI pin when the bus is idle,
there are some devices which are very fragile in this regard even when
the chip select signal is not asserted.  Otherwise we have some new
driver support, a bunch of small fixes and some general cleanup work.

 - Support for configuring the state of the MOSI pin when the the bus is
   idle.
 - Add the Elgin JG0309-01 in spidev.
 - Support for Marvell xSPI, Mediatek MTK7981, Microchip PIC64GX,
   NXP i.MX8ULP, and Rockchip RK3576 controllers.

I also accidentally pulled in an IIO DT bindings update due to a typo
when applying the MOSI idle state patches.

regulator: Updates for v6.12

This release is almost all cleanup work of various kinds, while the
diffstat for the core is quite large this is almost all cleanups and
documentation improvments with some small fixes rather than any new
feature work.  We do have support for a couple of new devices but these
are small additions to existing drivers rather than new drivers.

 - Removal of the SM5703 driver which does not have it's dependencies
   available.
 - Support for Allwinner AXP717, and Qualcomm WCN6855.

The Allwinner support shares some commits with the MFD tree.

regmap: Updates for v6.12

The main update here is Matti's work allowing regmap irqdomains to be
given custom names (allowing multiple interrupt controllers associatd
with a single struct device), this pulls in some commits from Thomas'
tree which it depends on.  Otherwise there's a bit of work on improving
handling of regmaps protected with spinlocks when used with complex
cache types, fixing some valid but harmless lockdep reports seen with
some new driver work.

Hi Linus,

Lot's of small things this time. The pull contains two merges of
immutable branches, one for the AXP717 support, which is shared
with MFD and one for the usb_types change, which is shared with
extcon to fix up a newly introduced driver using usb_types (also
touching a couple of other subsystems). Everything but the last
two commits have been in linux-next for at least 10 days. I only
pushed the last two commits some minutes ago. Those two are fixes
originally intended for 6.11. I received them a few days ago and
gave them some testing while travelling to Vienna. I independently
received a second patch fixing the issue, so it should be fixed
soon and I will be on vacation with limited network access for 3
weeks after LPC. Thus I think its better to have them included now
even though they received limited testing.

Greetings,

-- Sebastian

Hi Linus,

HSI changes for the 6.12 series

 * omap-ssi: remove unnecessary debugfs_create_dir() error check

Networking changes for 6.12.

The zero-copy changes are relatively significant, but regression risk
should be contained. The feature needs to be used to cause trouble.
The new code did trigger a PowerPC64 bug with GCC 14:

  https://lore.kernel.org/netdev/20240913125302.0a06b4c7@canb.auug.org.au/

a fix for which Michael will bring via his tree:

  https://lore.kernel.org/all/87jzffq9ge.fsf@mail.lhotse/

Unideal, not sure if you'll be willing to pull without that fix but
since we caught this recently I figured we'll defer to you during
the MW instead of trying to fix it cross-tree.

Also it feels like we got an order of magnitude more semi-automated
"refactoring" chaff than usual, I wonder if it's just us.

Core & protocols

This is the MTD PR for v6.12-rc1.

Thanks,
Miqu=C3=A8l

* MTD changes

No particularly important patchset this cycle, but we have a few usual
improvements: like using a better/more recent helper or checking a
return value.

* Raw NAND changes

The use of for_each_child_of_node_scoped() has been spread into the
subsystem drivers. Aside from that, a couple of exit path have been
fixed (mtk, denali), the TI GPMC bindings have been enhanced to comply
with up-to-date partition descriptions and as always there is a load of
small and misc fixes.

* SPI-NAND changes

The most impacting series this cycle is bringing support for continuous
reads in the SPI-NAND subsystem. This is a feature already merged in the
raw NAND subsystem which allows optimizing the internal fetch times in
the chip while reading sequential pages within an eraseblock. For now
only Macronix NANDs benefit from this feature. While we are talking
about Macronix, some of their chip need an explicit action for selecting
a different plane, and support for it has also been brought.

The bitflip threshold has also been set to the same arbitrary level as
in the raw NAND subsystem to optimize wear leveling decisions, and
finally support for a new Winbond chip has been added.

* SPI NOR changes

Notable changes:
- Add Write Protect support for N25Q064A.
- New flash support for Zetta ZD25Q128C and Spansion S28HS256T.
- Fix a NULL dereference in probe path for flashes without a name. The
  probe path tries to access the name without checking its existence
  first. S28HS256T is the first flash to define its entry without a
  name, uncovering this issue.

ARM:

* New Stage-2 page table dumper, reusing the main ptdump infrastructure

* FP8 support

* Nested virtualization now supports the address translation (FEAT_ATS1A)
  family of instructions

* Add selftest checks for a bunch of timer emulation corner cases

* Fix multiple cases where KVM/arm64 doesn't correctly handle the guest
  trying to use a GICv3 that wasn't advertised

* Remove REG_HIDDEN_USER from the sysreg infrastructure, making
  things little simpler

* Prevent MTE tags being restored by userspace if we are actively
  logging writes, as that's a recipe for disaster

* Correct the refcount on a page that is not considered for MTE tag
  copying (such as a device)

* When walking a page table to split block mappings, synchronize only
  at the end the walk rather than on every store

* Fix boundary check when transfering memory using FFA

* Fix pKVM TLB invalidation, only affecting currently out of tree
  code but worth addressing for peace of mind

LoongArch:

* Revert qspinlock to test-and-set simple lock on VM.

* Add Loongson Binary Translation extension support.

* Add PMU support for guest.

* Enable paravirt feature control from VMM.

* Implement function kvm_para_has_feature().

RISC-V:

* Fix sbiret init before forwarding to userspace

* Don't zero-out PMU snapshot area before freeing data

* Allow legacy PMU access from guest

* Fix to allow hpmcounter31 from the guest

sound updates for 6.12-rc1

A fairly big update at this time, both in core and driver sides.

The core received rewrites in PCM buffer allocation handling and
locking optimizations, PCM rate updates followed by lots of cleanups.

In ASoC side, the legacy Intel drivers have been deprecated by AVS
drivers which leaded to the significant amount of code reduction.
SoundWire driver updates and other cleanups contributed more code
reduction, too.

USB-audio driver received a large cleanup of its big quirk table, and
the old snd_print*() API usages in many legacy drivers are replaced
with the standard print API.

Here are some highlights:

Core:
- More optimized locking in ALSA control code
- Rewrites of memalloc helpers for better DMA API usage
- Drop of obsoleted vmalloc PCM buffer helper API
- Continued MIDI2 UMP updates
- Support of a new user-space driven timer instance
- Update for more PCM support rates and cleanups
- Xrun counter report in the proc files

ASoC:
- Continued simplification and cleanup works for ASoC
- Extensive cleanups and refactoring of the Soundwire drivers
- Removal of Intel machine support obsoleted by the AVS driver
- Lots of DT schema conversions
- Machine support for many AMD and Intel x86 platforms
- Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek RTL1320
  SoundWire and rev C, and Texas Instruments TAS2563

USB-audio:
- Add support of multiple control interfaces
- A large rewrite of quirk table with macros
- Support for RME Digiface USB

HD-audio:
- Cleanup of quirk code for Samsung Galaxy laptops
- Clean up of detection of Cirrus codecs
- C-Media CM9825 HD-audio codec support

Others:
- Rewrites to standard print API in a lot of legacy drivers

There's a trivial (and amusing) conflict with KVM s390 in the selftests pull
request (we both added "config" to the .gitignore, within a few days of each
other, after the goof being around for a good year or more).

Note, the pull requests are relative to v6.11-rc4.  I got a late start, and for
some reason thought kvm/next would magically end up on rc4 or later.

Note #2, I had a brainfart and put the testcase for verifying KVM's fastpath
correctly exits to userspace when needed in selftests, whereas the actual KVM
fix is in misc.  So if you run KVM selftests in the middle of pulling everything,
expect the debug_regs test to fail.

Here is the Smack pull request for v6.12.

There are 2 patches. One is a simple indentation correction.
The other corrects a potentially rcu unsafe pointer assignment.
Both have time in next and pass all tests.

Smack changes for v6.12
- rcu pointer assignment in smk_set_cipso
- indentation in smack_ip_output

Could you consider this pull request for 6.12-rc1? It's a bit earlier
due to our mid-autumn festival holidays next week.

In this cycle, we'd like to add file-backed mount support, which has
has been a strong requirement for years.  It is especially useful when
there are thousands of images running on the same host for containers
and other sandbox use cases, unlike OS image use cases.

Without file-backed mounts, it's hard for container runtimes  to manage
and isolate so many unnecessary virtual block devices safely and
efficiently, therefore file-backed mounts are highly preferred.
For EROFS users, ComposeFS [1], containerd, and Android APEXes [2] will
directly benefit from it, and I've seen no risk in implementing it as
a completely immutable filesystem.

The previous experimental feature "EROFS over fscache" is now marked as
deprecated because:

 - Fscache is no longer an independent subsystem and has been merged
   into netfs, which was somewhat unexpected when it was proposed.

 - New HSM "fanotify pre-content hooks" [3] will be landed upstream.
   These hooks will replace "EROFS over fscache" in a simpler way, as
   EROFS won't be bother with kernel caching anymore.  Userspace
   programs can also manage their own caching hierarchy more flexibly.

Once the HSM "fanotify pre-content hooks" is landed, I will remove the
fscache backend entirely as an internal dependency cleanup.  More
backgrounds are listed in the original patchset [4].

In addition to that, there are bugfixes and cleanups as usual as shown
below.  All commits have been in -next and no potential merge conflict
is observed.

Thanks,
Gao Xiang

 - Mark the experimental fscache backend as deprecated;

 - Handle overlapped pclusters caused by crafted images properly;

 - Fix a failure path which could cause infinite loops in
   z_erofs_init_decompressor();

 - Get rid of unnecessary NOFAILs;

 - Harmless on-disk hardening & minor cleanups.

Like a bunch of folks, I'll be living off conference coffee and canapes
for the next week or so, so here's the arm64 pull request for 6.12
before the chaos descends and the malnutrition sets in.

There's the usual summary in the tag, but the highlights are support for
Arm's "Permission Overlay Extension" using memory protection keys,
support for running as a protected guest on Android as well as perf
support for a bunch of new interconnect PMUs.

There's a trivial conflict with the kvmarm tree which was resolved in
linux-next as per [1]. Any issues, just yell.

This is the "last" part of the support for the new nbcon consoles.
Where "nbcon" stays for "No Big console lock CONsoles" aka not under
the console_lock.

New callbacks are added to struct console:

  - write_thread() for flushing nbcon consoles in task context.

  - write_atomic() for flushing nbcon consoles in atomic context,
    including NMI.

  - con->device_lock() and device_unlock() for taking the driver
    specific lock, for example, port->lock.

New printk-specific kthreads are created:

  - per-console kthreads which get responsible for flushing normal
    priority messages on nbcon consoles.

  - thread which gets responsible for flushing normal priority messages
    on all consoles when CONFIG_RT enabled.

The new callbacks are called under a special per-console lock which has
already been added back in v6.7. It allows to distinguish three severities:
normal, emergency, and panic. A context with a higher priority could take
over the ownership when it is safe even in the middle of handling a record.
The panic context could do it even when it is not safe. But it is allowed
only for the final desperate flush before entering the infinite loop.

The new lock helps to flush the messages directly in emergency and panic
contexts. But it is not enough in all situations:

  - console_lock() is still need for synchronization against boot consoles.

  - con->device_lock() is need for synchronization against other operations
    on the same HW, e.g. serial port speed setting, non-printk related
    read/write.

The dependency on con->device_lock() is mutual. Any code taking the driver
specific lock has to acquire the related nbcon console context as well.
For example, see the new uart_port_lock() API. It provides the necessary
synchronization against emergency and panic contexts where the messages
are flushed only under the new per-console lock.

Maybe surprisingly, a quite tricky part is the decision how to flush
the consoles in various situations. It has to take into account:

  - message priority: normal, emergency, panic

  - scheduling context: task, atomic, deferred_legacy

  - registered consoles: boot, legacy, nbcon

  - threads are running: early boot, suspend, shutdown, panic

  - caller: printk(), pr_flush(), printk_flush_in_panic(),
 console_unlock(), console_start(), ...

The primary decision is made in printk_get_console_flush_type(). It creates
a hint what the caller should do:

  - flush nbcon consoles directly or via the kthread

  - call the legacy loop (console_unlock()) directly or via irq_work

The existing behavior is preserved for the legacy consoles. The only
exception is that they are not longer flushed directly from printk() in
panic() before CPUs are stopped. But this blocking happens only when at
least one nbcon console is registered. The motivation is to increase
a chance to produce the crash dump. They legacy consoles might create
a deadlock in compare with nbcon consoles. The nbcon console should
allow to see the messages even when the crash dump fails.

There are three possible ways how nbcon consoles are flushed:

  - The per-nbcon-console kthread is responsible for flushing messages
    added with the normal priority. This is the default mode.

  - The legacy loop, aka console_unlock(), is used when there is still
    a boot console registered. There is no easy way how to match an early
    console driver with a nbcon console driver. And the console_lock()
    provides the only reliable serialization at the moment.

    The legacy loop uses either con->write_atomic() or con->write_thread()
    callbacks depending on whether it is allowed to schedule. The atomic
    variant has to be used from printk().

  - In other situations, the messages are flushed directly using
    write_atomic() which can be called in any context, including NMI.
    It is primary needed during early boot or shutdown, in emergency
    situations, and panic.

The emergency priority is used by a code called within
nbcon_cpu_emergency_enter()/exit(). At the moment, it is used in four
situations: WARN(), Oops, lockdep, and RCU stall reports.

Finally, there is no nbcon console at the moment. It means that the changes
should _not_ modify the existing behavior. The only exception is CONFIG_RT
which would force offloading the legacy loop, for normal priority context,
into the dedicated kthread.


Two thirds of the changes has already been in the pull request for 6.11.
The user-visible change is that the flushing is no longer postponed
in the emergency sections. The logic has been further simplified
by using printk_get_console_flush_type() already at this stage.

The new third of the changes added the write_thread() callback,
implemented the kthreads, and updated procfs and sysfs interfaces.

Hi Wolfram,

This turned out to be a fairly loaded pull request, covering a
variety of topics. There are four new platforms added, but the
bulk of it consists of cleanups and refactors.

I didnБ─≥t plan to have a second pull request during this merge
window. Everything that was submitted is included in this one.

Wishing you a great weekend and a fantastic conference week,
which IБ─≥m sorry to miss!

Andi

The DesignWare and the Renesas I2C drivers have received most of
the changes in this pull request.

The first has has undergone through a series of cleanups that
have been sent to the mailing list a year ago for the first time
and finally get merged in this pull request. They are many, from
typos (e.g. i2/i2c), to cosmetics, to refactoring (e.g. move
inline functions to librarieas) and many others.

Besides that, all the DesignWare Kconfig options have been
grouped under the I2C_DESIGNWARE_CORE and this required some
adaptation in many of the kernel configuration files for
different arm and mips boards.

Follows the list of the rest of the changes grouped by type of
change.

Cleanups
--------
The Qualcomm Geni platform improves the exit path in the runtime
resume function.

The Intel LJCA driver loses "target_addr" parameter in
ljca_i2c_stop() because it was unused.

The MediaTek controller intializes the restart_flag in the
transfer function using the ternary conditional operator ("? :")
instead of initializing it in different parts.

Constified a few global data structures in the virtio driver.

The Renesas driver simplifies the bus speed handling in the init
function making it more readable.

Improved an if/else statement in probe function of the Renesas
R-Car driver.

The iMX/MXC driver switches to using the RUNTIME_PM_OPS() instead
of SET_RUNTIME_PM_OPS().

Still in the iMX/MXC driver a comma ',' has been replaced by a
semicolon ';', while in different drivers the ',' has been
removed from the '{ }' delimiters.

Finally three devm_clk_get_enabled() have been used to simplify
the devm_clk_get/clk_prepare_enable tuple in the Renesas EMEV2,
Ingenic and MPC drivers.

Refactors
---------
The Nuvoton fixes a potential out of boundary array access. This
is not a bug fix because the issue could never occur due to
hardware not having the properties listed in the array. The
change makes the driver more future proof and, at the same time,
silences code analyzers.

Improvements

LoongArch KVM changes for v6.12

1. Revert qspinlock to test-and-set simple lock on VM.
2. Add Loongson Binary Translation extension support.
3. Add PMU support for guest.
4. Enable paravirt feature control from VMM.
5. Implement function kvm_para_has_feature().

sched_ext: Initial pull request for v6.12

This is the initial pull request of sched_ext. The v7 patchset
(https://lkml.kernel.org/r/20240618212056.2833381-1-tj@kernel.org) is
applied on top of tip/sched/core + bpf/master as of Jun 18th.

  tip/sched/core 793a62823d1c ("sched/core: Drop spinlocks on contention iff kernel is preempti
ble")
  bpf/master f6afdaf72af7 ("Merge branch 'bpf-support-resilient-split-btf'")

Since then, the following pulls were made:

- v6.11-rc1 is pulled to keep up with the mainline.

- tip/sched/core was pulled several times:

  - 7b9f6c864a34, 0df340ceae2e, 5ac998574f93, 0b1777f0fa04: To resolve
    conflicts. See each commit for details on conflicts and their
    resolutions.

  - d7b01aef9dbd: To receive fd03c5b85855 ("sched: Rework pick_next_task()")
    and related commits. @prev in added to sched_class->put_prev_task() and
    put_prev_task() is reordered after ->pick_task(), which makes
    sched_class->switch_class() unnecessary. The follow-up commits update
    sched_ext accordingly and drop sched_class->switch_class().

- bpf/master was pulled to receive baebe9aaba1e ("bpf: allow passing struct
  bpf_iter_<type> as kfunc arguments") and related changes in preparation
  for the DSQ iterator patchset

To obtain the net sched_ext changes, diff against:


which is the merge of:

  tip/sched/core bc9057da1a22 ("sched/cpufreq: Use NSEC_PER_MSEC for deadline task")
  bpf/master 2ad6d23f465 ("selftests/bpf: Do not update vmlinux.h unnecessarily")

Since the v7 patchset, the following changes were made:

- cpuperf support which was a part of the v6 patchset was posted separately
  and then applied after reviews.

- cgroup support which was a part of the v6 patchset was posted seprately,
  iterated and then applied.

- Improve integration with sched core.

- Double locking usage in migration paths dropped. Depend on
  TASK_ON_RQ_MIGRATING synchronization instead.

- The BPF scheduler couldn't directly dispatch to the local DSQ of another
  CPU using a SCX_DSQ_LOCAL_ON verdict. This caused difficulties around
  handling non-wakeup enqueues. Updated so that SCX_DSQ_LOCAL_ON can be used
  in the enqueue path too.

- DSQ iterator which was a part of the v6 patchset was posted separately.
  The iterator itself was applied after a couple revisions. The associated
  selective consumption kfunc can use further improvements and is still
  being worked on.

- scx_bpf_dispatch[_vtime]_from_dsq() added to increase flexibility. A task
  can now be transferred between two DSQs from almost any context. This
  involved significant refactoring of migration code.

- Various fixes and improvements.

As the branch is based on top of tip/sched/core + bpf/master, please merge
after both are applied.

workqueue: Changes for v6.12

Nothing major:

- workqueue.panic_on_stall boot param added.

- alloc_workqueue_lockdep_map() added (used by DRM).

- Other cleanusp and doc updates.

cgroup: Changes for v6.12

- cpuset isolation improvements.

- cpuset cgroup1 support is split into its own file behind the new config
  option CONFIG_CPUSET_V1. This makes it the second controller which makes
  cgroup1 support optional after memcg.

- Handling of unavailable v1 controller handling improved during cgroup1
  mount operations.

- union_find applied to cpuset. It makes code simpler and more efficient.

- Reduce spurious events in pids.events.

- Cleanups and other misc changes.

- Contains a merge of cgroup/for-6.11-fixes to receive cpuset fixes that
  further changes build upon.

The next week will be all conference travel for me and I'll be traveling in
the week after it too, so here's an early request to pull thermal control
updates for 6.12-rc1.

To receive them, please pull from the tag

 thermal-6.12-rc1


 Merge tag 'thermal-v6.12-rc1' of
ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/thermal/linux into


 thermal: of: Fix OF node leak in of_thermal_zone_find() error paths

to receive thermal control updates for 6.12-rc1.

These mostly continue to rework the thermal core and the thermal zone
driver interface to make the code more straightforward and reduce bloat.
The most significant piece of this work is a change of the code related
to binding cooling devices to thermal zones which, among other things,
replaces two previously existing thermal zone operations with one
allowing driver implementations to be much simpler.

There is also a new thermal core testing module allowing mock thermal
zones to be created and controlled via debugfs in order to exercise the
thermal core functionality.  It is expected to be used for implementing
thermal core self tests in the future.

Apart from the above, there are assorted thermal driver updates.

Specifics:

 - Update some thermal drivers to eliminate thermal_zone_get_trip()
   calls from them and get rid of that function (Rafael Wysocki).

 - Update the thermal sysfs code to store trip point attributes in trip
   descriptors and get to trip points via attribute pointers (Rafael
   Wysocki).

 - Move the computation of the low and high boundaries for
   thermal_zone_set_trips() to __thermal_zone_device_update() (Daniel
   Lezcano).

 - Introduce a debugfs-based facility for thermal core testing (Rafael
   Wysocki).

 - Replace the thermal zone .bind() and .unbind() callbacks for binding
   cooling devices to thermal zones with one .should_bind() callback
   used for deciding whether or not a given cooling devices should be
   bound to a given trip point in a given thermal zone (Rafael Wysocki).

 - Eliminate code that has no more users after the other changes, drop
   some redundant checks from the thermal core and clean it up (Rafael
   Wysocki).

 - Fix rounding of delay jiffies in the thermal core (Rafael Wysocki).

 - Refuse to accept trip point temperature or hysteresis that would lead
   to an invalid threshold value when setting them via sysfs (Rafael
   Wysocki).

 - Adjust states of all uninitialized instances in the .manage()
   callback of the Bang-bang thermal governor (Rafael Wysocki).

 - Drop a couple of redundant checks along with the code depending on
   them from the thermal core (Rafael Wysocki).

 - Rearrange the thermal core to avoid redundant checks and simplify
   control flow in a couple of code paths (Rafael Wysocki).

 - Add power domain DT bindings for new Amlogic SoCs (Georges Stark).

 - Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() in the ST
   driver and add a Kconfig dependency on THERMAL_OF subsystem for the
   STi driver (Raphael Gallais-Pou).

 - Simplify the error code path in the probe functions in the brcmstb
   driver with the help of dev_err_probe() (Yan Zhen).

 - Make imx_sc_thermal use dev_err_probe() (Alexander Stein).

 - Remove trailing space after \n newline in the Renesas driver (Colin
   Ian King).

 - Add DT binding compatible string for the SA8255p to the tsens thermal
   driver (Nikunj Kela).

 - Use the devm_clk_get_enabled() helpers to simplify the init routine
   in the sprd thermal driver (Huan Yang).

 - Remove __maybe_unused notations for the functions by using the new
   RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros on the IMx and
   Qoriq drivers (Fabio Estevam)

 - Remove unused declarations from the ti-soc-thermal driver's header
   file as the functions in question were removed previously (Zhang
   Zekun).

 pm-6.12-rc1




 Linux 6.11-rc7

By the number of new lines of code, the most visible change here is the
addition of hybrid CPU capacity scaling support to the intel_pstate
driver.  Next are the amd-pstate driver changes related to the
calculation of the AMD boost numerator and preferred core detection.

As far as new hardware support is concerned, the intel_idle driver will
now handle Granite Rapids Xeon processors natively, the intel_rapl power
capping driver will recognize family 1Ah of AMD processors and Intel
ArrowLake-U chipos, and intel_pstate will handle Granite Rapids and
Sierra Forest chips in the out-of-band (OOB) mode.

Apart from the above, there is a usual collection of assorted fixes
and code cleanups in many places and there are tooling updates.

Specifics:

 - Remove LATENCY_MULTIPLIER from cpufreq (Qais Yousef).

 - Add support for Granite Rapids and Sierra Forest in OOB mode to the
   intel_pstate cpufreq driver (Srinivas Pandruvada).

   Ugwekar).

 - Minor cleanups for loongson, cpufreq-dt and powernv cpufreq drivers
   (Danila Tikhonov, Huacai Chen, and Liu Jing).

 - Make amd-pstate validate return of any attempt to update EPP limits,
   which fixes the masking hardware problems (Mario Limonciello).

 - Move the calculation of the AMD boost numerator outside of amd-pstate,
   correcting acpi-cpufreq on systems with preferred cores (Mario
   Limonciello).

 - Harden preferred core detection in amd-pstate to avoid potential
   false positives (Mario Limonciello).

 - Add extra unit test coverage for mode state machine (Mario
   Limonciello).

 - Fix an "Uninitialized variables" issue in amd-pstate (Qianqiang Liu).

 - Add Granite Rapids Xeon support to intel_idle (Artem Bityutskiy).

 - Disable promotion to C1E on Jasper Lake and Elkhart Lake in

Hi,

this update brings mostly refactoring, cleanups, minor performance
optimizations and usual fixes. The folio API conversions are most
noticeable.

There's one less visible change that could have a high impact. The
extent lock scope for read is reduced, not held for the entire
operation. In the buffered read case it's left to page or inode lock,
some direct io read synchronization is still needed.

This used to prevent deadlocks induced by page faults during direct io,
so there was a 4K limitation on the requests, e.g. for io_uring. In the
future this will allow smoother integration with iomap where the extent
read lock was a major obstacle.


User visible changes:

- the FSTRIM ioctl updates the processed range even after an error or
  interruption

- cleaner thread is woken up in SYNC ioctl instead of waking the
  transaction thread that can take some delay before waking up the
  cleaner, this can speed up cleaning of deleted subvolumes

- print an error message when opening a device fail, e.g. when it's
  unexpectedly read-only

Core changes:

- improved extent map handling in various ways (locking, iteration, ...)

- new assertions and locking annotations

- raid-stripe-tree locking fixes

- use xarray for tracking dirty qgroup extents, switched from rb-tree

- turn the subpage test to compile-time condition if possible (e.g. on
  x86_64 with 4K pages), this allows to skip a lot of ifs and remove
  dead code

- more preparatory work for compression in subpage mode

Cleanups and refactoring

- folio API conversions, many simple cases where page is passed so
  switch it to folios

- more subpage code refactoring, update page state bitmap processing

- introduce auto free for btrfs_path structure, use for the simple cases

Hi,

please pull the following cleanups removing unused code and updating
definition of flexible struct array.

Hi Joerg,

support for NVIDIA's virtual command queue implementation for SMMUv3,
but everything is summarised in the tag.

** Please note **: I've already pushed this to the arm/smmu branch for
-next coverage, but I thought sending a pull request was still useful
for the records and the signed tag. If you want to recreate the branch,
please feel free.

See you at LPC!

Arm SMMU updates for 6.12

- SMMUv2:
  * Devicetree binding updates for Qualcomm MMU-500 implementations.
  * Extend workarounds for broken Qualcomm hypervisor to avoid touching
    features that are not available (e.g. 16KiB page support, reserved
    context banks).

- SMMUv3:
  * Support for NVIDIA's custom virtual command queue hardware.
  * Fix Stage-2 stall configuration and extend tests to cover this area.
  * A bunch of driver cleanups, including simplification of the master
    rbtree code.

- Plus minor cleanups and fixes across both drivers.

- use devm_clk_get_enabled() helper
- prototype fixes
- cleanup unused stuff

in the SGX NUMA allocator. It's probably only triggerable today on
servers with buggy BIOSes, but it's theoretically possible it can
happen on less goofy systems.

USB-serial updates for 6.12-rc1

Here are the USB-serial updates for 6.12-rc1, including:

 - fix kobil_sct initial terminal settings
 - set driver owner when registering drivers

All have been in linux-next with no reported issues.

Hi Rafael,


This cpupower second update for Linux 6.12-rc1 consists of a fix
and a new feature.

-- adds missing powercap_set_enabled() stub function
-- adds SWIG bindings files for libcpupower

SWIG is a tool packaged in Fedora and other distros that can generate
bindings from C and C++ code for several languages including Python,
Perl, and Go.

These bindings allows users to easily write scripts that use and extend
libcpupower's functionality. Currently, only Python is provided in the
makefile, but additional languages may be added if there is demand.

Note that while SWIG itself is GPL v3+ licensed; the resulting output,
the bindings code, is permissively licensed + the license of the .o
files. Please see the following for more details.

   EMC/MC, Atmel EBI, Samsung Exynos5422 DMC, STM32 FMC2 EBI, OMAP GPMC,
   PL172 and PL1353 SMC.  These are mostly code simplifying around
   probe() like using
    - devm_clk_get_enabled(),
    - dev_err_probe(),
    - scoped device node handling (cleanup.h),
    - scoped for each OF child loops,
    - scoped/guard locks.

Samsung pinctrl drivers changes for v6.12

1. Few cleanups: use more appropriate of_property_present(), use scoped
   OF nodes handling and switch to kmemdup_array().

2. Implement configuring pull-up and pull-down via GPIOLIB.

Samsung SoC drivers for v6.12

1. Improve Samsung USI (Universal Serial Interface) DT binding,
2. Cleanup old Samsung MFC TXT binding.

Hi Shuah,

nolibc changes for 6.12

Highlights

Hi Arnd,

have been in linux-next since August 9th.

Thanks,

T-HEAD Devicetrees for v6.12

Add SPI controller node to th1520.dtsi and enable spi0 on the BeagleV
Ahead and LicheePi 4A.

The TH1520 AP_SYS clock driver landed in v6.11 so convert multiple
peripherals like mmc and uart from fixed clocks to the clock controller.

All of these patches have been in linux-next since next-20240809.

Hi Peter & Ingo,

Per discussion:

https://lore.kernel.org/lkml/20240802151619.GN39708@noisy.programming.kicks-ass.net/

I'm sending a PR with some lockdep changes to tip.


Lockdep changes for v6.12:

- Fixes a deadlock in lockdep by avoiding calling rcu with the graph
  lock held.
- Uses str_plural() to fix Coccinelle warning.
- Uses seq_putc() instead of seq_printf() to print a single character in
  lockdep proc file.

Boqun
