| * | | ide: Add tx4938ide driver (v2)Atsushi Nemoto2008-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | ide: Add tx4939ide driver (v6)Atsushi Nemoto2008-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This code is redundant -- the switching for READ and WRITE is already handled in scsi_io_completion() and the switching for MODE SENSE is already handled in scsi_mode_sense(). (There is no comparable switch for MODE SELECT, but I doubt one is needed.) Furthermore the other handlers do a better job; they check for appropriate ASC and ASCQ values before blindly switching the size. The code in sd.c is known to cause problems with some devices by switching when it shouldn't.

We have seen cases of arrays returning with NO_SENSE (no error), but the I/O was not completely transferred, thus residual set. Thus, rather than return good_bytes as the entire transfer, set good_bytes to 0, so that the midlayer then applies the residual in calculating the transfer, and for sd, will fail the I/O and fall into a retry path.

| * | | | | | [SCSI] export busy state via q->lld_busy_fn()Kiyoshi Ueda2008-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements q->lld_busy_fn() for scsi mid layer to export its busy state for request stacking drivers. For efficiency, no lock is taken to check the busy state of shost/starget/sdev, since the returned value is not guaranteed and may be changed after request stacking drivers call the function, regardless of taking lock or not. When scsi can't dispatch I/Os anymore and needs to kill I/Os (e.g. !sdev), scsi needs to return 'not busy'. Otherwise, request stacking drivers may hold requests forever.

There should be no functional change. This is a preparation for another patch which exports scsi's busy state to the block layer for request stacking drivers.

If something fails before complete recovery, it should remain on, since it is a diagnostics LED, reason for the used higher layer for the clear.
