| * [SCSI] libata: implement minimal transport template for ->eh_timed_outTejun Heo2006-03-211-1/+0
| | | | | | | | | | | | | | | | | | | | 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.

* | [libata] sata_mv: off-by-1 fixMark Lord2006-03-211-1/+4
|/ | | | | | | | | | | | This patch addresses a number of weird behaviours observed for the sata_mv driver, by fixing an "off by one" bug in processing of the EDMA response queue. Basically, sata_mv was looking in the wrong place for command results, and this produced a lot of unpredictable behaviour.

* [libata] sata_mv: fix irq port status usageJeff Garzik2006-03-201-1/+1
| | | | | | | | | Interrupt handler did not properly initialize a variable on a per-port basis, leading to incorrect behavior on ports other than port 0. Bug caught and fixed by Mark Lord. Signed-off-by: Jeff Garzik <jeff@garzik.org>

| * [libata sata_mv] do not enable PCI MSI by defaultJeff Garzik2006-02-021-1/+10
| | | | | | | | | | | | | | | | | | | | Several bug reports have come in, noting that disabling CONFIG_PCI_MSI has fixed their problems with this driver. This may be generic system issues, but there is also the probability of unimplemented hardware errata workarounds. Until this ream of bug reports is sorted out, we can get them going in non-MSI interrupt mode. As such, this change adds an 'msi' module option, which defaults to off.

| | | | | | | | | | | | | | | | | | | | | | Implement ata_eh_qc_complete/retry() using scsi_eh_finish_cmd() and scsi_eh_flush_done_q(). This removes all eh scsicmd finish hacks from low level drivers. This change was first suggested by Jeff Garzik.

| | | | | | | | | | | | | | | | | | Return AC_ERR_* mask from issue fuctions instead of 0/-1. This enables things like failing a qc with AC_ERR_HSM when the device doesn't set DRDY when the qc is about to be issued.

|/ | | | | | | | | | | 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...). After proper error diagnosis is implemented, sense data should also be generated from err_mask instead of directly from hardware tf registers as it is currently.

| * [libata] mark certain hardware (or drivers) with a no-atapi flagJeff Garzik2005-12-131-1/+2
| | | | | | | | | | | | | | | | | | | | Some hardware does not support the PACKET command at all. Other hardware supports ATAPI, but the driver does something nasty such as calling BUG() when an ATAPI command is issued. For these such cases, we mark them with a new flag, ATA_FLAG_NO_ATAPI. Initial version contributed by Ben Collins.

* [libata sata_mv] handle lack of hardware nIEN supportJeff Garzik2005-11-171-1/+6
| | | | | | | | | | | Handle errata (it was unintentional on this h/w, whereas its intentional on others) whereby the nIEN bit in Device Control is ignored, leading to a situation where a hardware interrupt completes the qc before the polling code has a chance to. This will get fixed The Right Way(tm) once Albert Lee's irq-pio branch is merged, as the more natural PIO method on this hardware is interrupt-driven.
* [libata sata_mv] SATA probe, DMA boundary fixesJeff Garzik2005-11-171-18/+70
| | | | | | | | - DMA boundary was being handled incorrectly. Copied the code from ata_fill_sg(), since Marvell has the same DMA boundary needs. (we can't use ata_fill_sg directly since we have different hardware descriptors) - cleaned up the SATA phy reset code, to deal with various errata

| * [libata] change ata_qc_complete() to take error mask as second argJeff Garzik2005-10-301-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
