http://dri.freedesktop.org/wiki/DRM Is it possible to make a DRI driver without a DRM driver in a piece of hardware whereby we do all accelerations in PIO mode? The kernel provides three main things: * the ability to wait on a contended lock (the waiting process is put to sleep), and to free the lock of a dead process; * the ability to mmap areas of memory that non-root processes can't usually map; * the ability to handle hardware interruptions and a DMA queue. All of these are hard to do outside the kernel, but they aren't required components of a DRM driver. For example, the tdfx driver doesn't use hardware interrupts at all -- it is one of the simplest DRM drivers, and would be a good model for the hardware you are thinking about (in it's current form, it is quite generic).
