* [PATCH] libata: implement ata_eh_wait()Tejun Heo2006-05-31
| | | | | | | | | Implement ata_eh_wait(). On return from this function, it's guaranteed that the EH which was pending or in progress when the function was called is complete - including the tailing part of SCSI EH. This will be used by hotplug and others to synchronize with EH. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] libata: set PIO-0 after successful EH resetTejun Heo2006-05-31
| | | | | | | | | Set ata_device->pio_mode to XFER_PIO_0 after a successful reset. This is to keep EH resets consistent with probe resets as updated by the commit b6079ca409bf88c248992e96510dd6f610f7ed89. Note that, with soon-to-follow hotplug update, EH resets will include probe resets. Signed-off-by: Tejun Heo <htejun@gmail.com>
* libata debugging: set initial dbg valueBorislav Petkov2006-05-29
| | | | | | | | | | | This patch sets the prerequisites for the new debugging scheme that more or less resembles Donald Becker's net driver example. This one liner doesn't change any functionality beside setting the appropriate debug level for the msg_enable control in the ata_port struct, which will be later used by the ata_msg_* macros to control the amount of debug information sent to printk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Okay, just to sum things up. This forces libata to wait for up to 2 seconds for BUSY|DRQ to clear on resume before continuing. [jgarzik adds...] During testing we never saw DRQ asserted, but nonetheless (a) this works and (b) testing for DRQ won't hurt.

* | [PATCH] SCSI: make scsi_implement_eh() generic API for SCSI transportsTejun Heo2006-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | libata implemented a feature to schedule EH without an associated EH by manipulating shost->host_eh_scheduled in ata_scsi_schedule_eh() directly. Move this function to scsi_error.c and rename it to scsi_schedule_eh(). It is now an exported API for SCSI transports and exported via new header file drivers/scsi/scsi_transport_api.h This patch also de-export scsi_eh_wakeup() which was exported specifically for ata_scsi_schedule_eh().

* | [PATCH] libata: enforce default EH actionsTejun Heo2006-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | LLDDs rely on libata that certain EH actions are automatically taken on some errors. If the port is frozen or one or more qc's have failed with HSM violation or timeout, softreset is enforced (LLDD can ask for storonger EH action at will). If any other error condition exists, libata EH always revalidates. This behavior existed in earlier revisions of new EH but lost during development process. This patch restores it.

| * [PATCH] sata_mv: remove local copy of queue indexesMark Lord2006-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | The driver currently keeps local copies of the hardware request/response queue indexes. But it expends significant effort ensuring consistency between the two views, and still gets it wrong after an error or reset occurs. This patch removes the local copies, in favour of just accessing the hardware whenever we need them. Eventually this may need to be tweaked again for NCQ, but for now this works and solves problems some users were seeing.

| * [PATCH] sata_mv: spurious interrupt workaroundMark Lord2006-05-20
| | | | | | | | | | | | | | | | | | | | | | | | The 60xx chips, and possibly others, incorrectly assert DEV_IRQ interrupts on a regular basis. The cause of this is under investigation (by me and in theory by Marvell also), but regardless we do need to deal with these events. This patch tidies up some interrupt handler code, and ensures that we ignore DEV_IRQ interrupts when the drive still has ATA_BUSY asserted.

| * [PATCH] sata_mv: chip initialization fixesMark Lord2006-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | The interface control register of the 60xx (and later) Marvell chip requires certain bits to always be set when writing to it. These bits incorrectly read-back as zeros, so the pattern must be ORed in with each write of the register. Also, bit 12 should NOT be set (note that Marvell's own driver also had bit-12 wrong here). While we're at it, we also now do pci_set_master() in the init code. Signed-off-by: Mark Lord <liml@rtr.ca> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [PATCH] sata_mv: deal with interrupt coalescing interruptsMark Lord2006-05-20
| | | | | | | | | | | | | | | | | | In some systems, it is possible that the BIOS may have enabled interrupt coalescing for the Marvell controllers which support it.

| * [PATCH] sata_mv: prevent unnecessary double-resetsMark Lord2006-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The mv_err_intr() function is invoked from the driver's interrupt handler, as well as from the timeout function. This patch prevents it from triggering a one-after-the-other double reset of the controller when invoked from the timeout function. This also adds a check for a timeout race condition that has been observed to occur with this driver in earlier kernels. This should not be needed, in theory, but in practice it has caught bugs. Maybe nuke it at a later date. Signed-off-by: Mark Lord <liml@rtr.ca> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Note that NCQ commands don't use ata_rwcmd_protocol() to choose ATA command. This is because, unlike non-NCQ RW commands, NCQ commands can only be used for NCQ protocol and FUA handling is done with a flag rather than separate command. NCQ enabled device will have queue depth larger than one but no two non-NCQ commands can be issued simultaneously, neither can a non-NCQ command and NCQ commands. This patch makes ata_scsi_translate() return SCSI_MLQUEUE_DEVICE_BUSY if such exclusion is necessary. SCSI midlayer will retry the command later. As SCSI midlayer always retries once a command completes, this doesn't incur unnecessary delays and as most commands will be NCQ ones for NCQ device, so the overhead should be negligible. Initial implementation is from Jens Axboe and using SCSI_MLQUEUE_DEVICE_BUSY for exclusion is suggested by Jeff Garzik. Signed-off-by: Tejun Heo <htejun@gmail.com>

The distinction between ap->qc_active and ap->sactive is also useful for later PM implementation. Signed-off-by: Tejun Heo <htejun@gmail.com>
