2006-04-10[PATCH] move ->eh_strategy_handler to the transport classChristoph Hellwig
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.

2006-03-21[SCSI] libata: implement minimal transport template for ->eh_timed_outTejun Heo
SCSI midlayer has moved hostt->eh_timed_out to transport template. As libata doesn't need full-blown transport support yet, implement minimal transport for libata. No transport class or whatsoever, just empty transport template with ->eh_timed_out hook. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-03-11[PATCH] ahci: enable prefetching for PACKET commandsTejun Heo

2006-02-12[PATCH] libata: move cdb_len for host to deviceTejun Heo
cdb_len is per-device property. Sharing cdb_len on ap results in inaccurate configuration on revalidation and hotplugging. This patch makes cdb_len per-device. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jgarzik@pobox.com>

2006-01-26[PATCH] libata: return AC_ERR_* from issue functionsTejun Heo

2006-01-26[PATCH] libata: add detailed AC_ERR_* flagsTejun Heo
Add detailed AC_ERR_* flags and use them. Long-term goal is to describe all errors with err_mask and tf combination (tf for failed sector information, etc...).

2005-11-16[libata ahci] tone down ATAPI errorsJeff Garzik
ATA devices don't generate many errors, so the preferred method is to printk() when they occur. ATAPI devices generate tons of exceptions during the normal course of operation, so this change skips logging the most common class of errors.
2005-11-15[libata ahci] command completion fixes, improved debug msgsJeff Garzik
- Fix a regression in command completion, which prevented the restart of the DMA engine after the device throws an error. - Pack more hardware info into the port-reset error message. - Promote "welcome to our timeout" message from debug msg to normal printk.
2005-11-14[libata ahci] error handling fixesJeff Garzik
Needed to get ATAPI working. - dump hardware error bits, if hardware signals an error - only reset hardware during timeout if a command was active - call ata_qc_complete() with a fine-grained error mask. Needed so that atapi_qc_complete() can distinguish between device errors and other errors.
2005-11-12[libata ahci] set port ATAPI bit correctlyJeff Garzik
Although according to the documentation this largely only affects desktop LED control, let's make sure we set the ATAPI bit when we have an ATAPI device attached to the port.
2005-11-12[libata ahci, qstor] fix miscount of scatter/gather entriesJeff Garzik
Don't directly reference qc->n_elem, as that might cause an off-by-one error for misaligned (padded) ATAPI transfers.

2005-10-30[libata] change ata_qc_complete() to take error mask as second argJeff Garzik
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.
