ide: Add tx4938ide driver (v2)

2008-10-23T21:22:08+00:00

This is the driver for the Toshiba TX4938 SoC EBUS controller ATA mode. It has custom set_pio_mode and some hacks for big endian. Signed-off-by: Atsushi Nemoto Cc: ralf@linux-mips.org Cc: sshtylyov@ru.mvista.com Signed-off-by: Bartlomiej Zolnierkiewicz

ide: Add tx4939ide driver (v6)

2008-10-23T21:22:07+00:00

This is the driver for the Toshiba TX4939 SoC ATA controller. This controller has standard ATA taskfile registers and DMA command/status registers, but the register layout is swapped on big endian. There are some other endian issue and some special registers which requires many custom dma_ops/tp_ops routines and build_dmatable.

ide: add generic ATA/ATAPI disk driver

2008-10-17T16:09:14+00:00

* Add struct ide_disk_ops containing protocol specific methods. * Add 'struct ide_disk_ops *' to ide_drive_t. * Convert ide-{disk,floppy} drivers to use struct ide_disk_ops. * Merge ide-{disk,floppy} drivers into generic ide-gd driver.

ide: Implement disk shock protection support (v4)

2008-10-13T19:39:50+00:00

On user request (through sysfs), the IDLE IMMEDIATE command with UNLOAD FEATURE as specified in ATA-7 is issued to the device and processing of the request queue is stopped thereafter until the specified timeout expires or user space asks to resume normal operation. This is supposed to prevent the heads of a hard drive from accidentally crashing onto the platter when a heavy shock is anticipated (like a falling laptop expected to hit the floor). Port resets are deferred whenever a device on that port is in the parked state. v3: Elias Oltmanns wrote: [...] > >> 1.

Additionally, we should plug the queue when enqueueing the unpark request because there is no guarantee that the park timeout has not expired by then. Even though the chance for that to happen is very slim, the request might end up hanging in the queue until the next I/O operation is queued up. While at it, clean up the code a little: - make issue_park_cmd() a function of type void since nobody cares for the return value anyway; - use blk_start_queueing() instead of __blk_run_queue() since we don't have to worry about recursion; - remove a superfluous pointer deference in task_no_data_intr().
