* [PATCH] libata-hp: hook warmplugTejun Heo2006-05-311-0/+1
| | | | | | Hook transportt->user_scan() and hostt->slave_destroy(). Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] PATCH: libata. Add ->data_xfer methodAlan Cox2006-05-241-0/+1
| | | | | | | | | | | We need to pass the device in order to do per device checks such as 32bit I/O enables. With the changes to include dev->ap we now don't have to add parameters however just clean them up. Also add data_xfer methods to the existing drivers except ata_piix (which is in the other block of patches). If you reject the piix one just add a data_xfer to it...

| | * [PATCH] move ->eh_strategy_handler to the transport classChristoph Hellwig2006-04-101-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Overriding the whole EH code is a per-transport, not per-host thing. Move ->eh_strategy_handler to the transport class, same as ->eh_timed_out. Downside is that scsi_host_alloc can't check for the total lack of EH anymore, but the transition period from old EH where we needed it is long gone already.

| | * [PATCH] libata: fix WARN_ON() condition in *_fill_sg()Tejun Heo2006-02-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For ATAPI commands, padding can reduce qc->n_elem by one and thus to zero making assert(qc->n_elem > 0)'s in ata_fill_sg() and qs_fill_sg() fail for legal commands. This patch fixes the assert()'s to take qc->pad_len into account. Although the condition check seems a bit excessive, as this part of code isn't still stable yet, I think it's worth to keep those.

| * | | | [libata] change ata_qc_complete() to take error mask as second argJeff Garzik2005-10-301-3/+4
| | |_|/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The second argument to ata_qc_complete() was being used for two purposes: communicate the ATA Status register to the completion function, and indicate an error. On legacy PCI IDE hardware, the latter is often implicit in the former. On more modern hardware, the driver often completely emulated a Status register value, passing ATA_ERR as an indication that something went wrong. Now that previous code changes have eliminated the need to use drv_stat arg to communicate the ATA Status register value, we can convert it to a mask of possible error classes. This will lead to more flexible error handling in the future.

| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | | | | We want ->tf_read() to get a complete snapshot of all taskfile registers, without requiring the callers to manually call ata_chk_status() and ata_chk_err() themselves. This also fixes a minor bug in sata_vsc where the lower bits of the feature register were incorrectly placed in the HOB (high order bits) portion of struct ata_taskfile.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | sata_qstor strays into a nasty area - gcc handling of wide enums is full of bugs that got fixed between gcc versions creating portability nightmare. Single-member enums are safe, so are ones that stay within the range of int or unsigned int. Anything beyond that is asking for trouble. Declaration of constants split in two enums, taking the ~0UL one into a separate enum. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>
