NAME

ftl_cs - Flash Translation Layer driver for PCMCIA memory cards
 

SYNOPSIS

DESCRIPTION

The ftl_cs driver allocates a major device number when it is loaded. Minor device numbers have a bitwise layout of 'dddrrppp'. 'ddd' is the device number, with one card counting as one device. 'rr' is the common-memory region number, generally 0. And 'ppp' selects a logical partition within the FTL region.

The default configuration script for FTL devices will create a block device with the name of the form '/dev/ftl{d}c{r}', where '{d}' is the device number and '{r}' is the region number, that spans the entire FTL region. It also creates devices '/dev/ftl{d}c{r}p[1-4]' pointing to partitions 1 through 4 within this FTL region.

An FTL region must be formatted before use. The formatting utility, ftl_format, needs to write to the corresponding raw memory device rather than the FTL device interface.  

PARAMETERS

pc_debug=n

Selects the PCMCIA debugging level. This parameter is only available if the module is compiled with debugging enabled. A non-zero value enables debugging.

major_dev=n

Selects the major device number to allocate for FTL devices. The default is to pick any available major number.
