2006-06-11[PATCH] sata_mv: grab host lock inside eng_timeoutMark Lord
Bug fix: mv_eng_timeout() calls mv_err_intr() without first grabbing the host lock, which can lead to all sorts of interesting scenarios. This whole error-handling portion of sata_mv is nasty (and will get fixed for the new EH stuff), but for now this patch will help keep it on life-support.

2006-05-24[PATCH] PATCH: libata. Add ->data_xfer methodAlan Cox
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...

2006-05-20[PATCH] sata_mv: endian fixMark Lord
This fixes a byte-swap issue on PPC, found by Zang Roy-r61911 on the powerpc platform. His original patch also had some other platform-specific changes in #ifdef's, but I'm not sure yet how to incorporate them. Look for another patch for those (soon).

2006-05-20[PATCH] sata_mv: remove local copy of queue indexesMark Lord
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.

2006-05-20[PATCH] sata_mv: spurious interrupt workaroundMark Lord
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.

2006-05-20[PATCH] sata_mv: chip initialization fixesMark Lord
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>
2006-05-20[PATCH] sata_mv: deal with interrupt coalescing interruptsMark Lord
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>
2006-05-20[PATCH] sata_mv: prevent unnecessary double-resetsMark Lord
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>

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.

2006-04-01[PATCH] libata: implement ata_dev_enabled and disabled()Tejun Heo
This patch renames ata_dev_present() to ata_dev_enabled() and adds ata_dev_disabled(). This is to discern the state where a device is present but disabled from not-present state. This disctinction is necessary when configuring transfer mode because device selection timing must not be violated even if a device fails to configure.

2006-03-29[PATCH] sata_mv: three bug fixesMark Lord
(1) A DMA transfer size of 0x10000 was not being written as 0x0000 in the PRDs. Fixed. (1) The DEV_IRQ interrupt cause bit happens spuriously during EDMA operation, and was not being ignored by the driver. This led to various "drive busy" errors being reported, with associated unpredictable behaviour. Fixed. (2) If a SATA or PCI interrupt was received with no outstanding command, the interrupt handler still attempted to invoke ata_qc_complete(), triggering assert()/BUG_ON() behaviour elsewhere in libata. Fixed. The driver still has issues with confusion after error-recovery, but should now be reliable in the absence of drive errors. I will be looking more into the error-handling bugs next.

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.
