* | [PATCH] Suspend support for libataJens Axboe2006-01-06
|/ | | | | | | | | | | | | | | | This patch adds suspend patch to libata, and ata_piix in particular. For most low level drivers, they should just need to add the 4 hooks to work. As I can only test ata_piix, I didn't enable it for more though. Suspend support is the single most important feature on a notebook, and most new notebooks have sata drives. It's quite embarrassing that we _still_ do not support this. Right now, it's perfectly possible to suspend the drive in mid-transfer.

| * [PATCH] fix libata inquiry VPD for ATAPI devicesTony Battersby2005-12-24
| | | | | | | | | | | | | | | | | | | | | | | | | | The following patch prevents libata from incorrectly modifying inquiry VPD pages and command support data from ATAPI devices. I have tested the patch with a SATA ATAPI tape drive on an AHCI controller. Patch is against kernel 2.4.32 with 2.4.32-libata1.patch applied. Anthony J.

| * [libata] mark certain hardware (or drivers) with a no-atapi flagJeff Garzik2005-12-13
| | | | | | | | | | | | | | | | | | | | 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] REQUEST SENSE handling fixesJeff Garzik2005-11-14
| | | | | | | | - Move ATAPI check-condition handling out of the timeout handler - Use multi-qc-issue feature to issue REQUEST SENSE ATAPI PACKET command upon receiving an ATAPI check-condition. This cleans things up a lot, and eliminates a nasty recursion bug.

| * [libata] locking rewrite (== fix)Jeff Garzik2005-10-30
| | | | | | | | | | | | | | | | | | | | | | | | A lot of power packed into a little patch. This change eliminates the sharing between our controller-wide spinlock and the SCSI core's Scsi_Host lock. As the locking in libata was already highly compartmentalized, always referencing our own lock, and never scsi_host::host_lock. As a side effect, this change eliminates a deadlock from calling scsi_finish_command() while inside our spinlock.

| * [libata] change ata_qc_complete() to take error mask as second argJeff Garzik2005-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The ide-scsi driver sets max_lun to a value greater than under certain conditions: if ((drive->id->last_lun & 0x7) != 7) host->max_lun = (drive->id->last_lun & 0x7) + 1; else host->max_lun = 1; last_lun is Word 126 of IDENTIFY PACKET DEVICE, marked as obsolete and undocumented in non-ancient specs. We'll leave it out for now. Should the need arise to support multi-LUN ATAPI devices, we'll probably want to add the above code. Finally, there have been reports of REPORT LUNS commands locking up ATAPI drives. Eliminating the wildcard LUN scan could help reduce the trouble from problematic drives.
