* [PATCH] libata-hp-prep: use __ata_scsi_find_dev()Tejun Heo2006-05-31
| | | | | | Convert direct sdev -> dev lookup to __ata_scsi_find_dev(). Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] libata-hp-prep: update ata_scsi_find_dev() and friendsTejun Heo2006-05-31
| | | | | | | | Separate out ata_find_dev() and __ata_scsi_find_dev() from ata_scsi_find_dev(). These will be used by later hotplug implementation. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [PATCH] libata-hp-prep: make some ata_device fields persistentTejun Heo2006-05-31
| | | | | | | | | | | | | | | Lifetimes of some fields span over device plugging/unplugging. This patch moves such persistent fields to the top of ata_device and separate them with ATA_DEVICE_CLEAR_OFFSET. Fields above the offset are initialized once during host initializatino while all other fields are cleared before hotplugging. Currently ->ap, devno and part of flags are persistent. Note that flags is partially cleared while holding host_set lock. This is to synchronize with later warm plug implementation which will record hotplug request in dev->flags.

* [PATCH] libata-hp-prep: implement ata_dev_init()Tejun Heo2006-05-31
| | | | | | | | Move initialization of struct ata_device into ata_dev_init() in preparation for hotplug. This patch calls ata_dev_init() from ata_host_init() and thus makes no functional difference. Signed-off-by: Tejun Heo <htejun@gmail.com>
* [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.

| | | | | | | | | | | | | | | | | | | | | | 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] 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. This patch adds code to detect/ack interrupts from the chip's coalescing (combing) logic. Signed-off-by: Mark Lord <liml@rtr.ca> Signed-off-by: Jeff Garzik <jeff@garzik.org>
| * [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>
