* libata: kill spurious NCQ completion detectionTejun Heo2007-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Spurious NCQ completion detection implemented in ahci was incorrect. On AHCI receving and processing FISes and raising interrupts are not interlocked and spurious interrupts are expected. For example, if an interrupt occurs while interrupt handler is running and the running interrupt handler handles the event the new IRQ indicated, after IRQ handler finishes, it will be executed again because IRQ pending bit is set by the new interrupt but there won't be anything to process. Please read the following message for more information. http://article.gmane.org/gmane.linux.ide/26012 This patch... * Removes all spurious IRQ whining from ahci. Spurious NCQ completion detection was completely wrong. Spurious D2H Register FIS taught us that some early drives send spurious D2H Register FIS with I bit set while NCQ commands are in progress but none of recent drives does that and even the ones which show such behavior can do NCQ fine. * Kills all NCQ blacklist entries which were added because of spurious NCQ completions. I tracked down each commit and verified all removed ones are actually added because of spurious completions. WD740ADFD-00NLR1 wasn't deleted but moved upward because the drive not only had spurious NCQ completions but also is slow on sequential data transfers if NCQ is enabled. Maxtor 7V300F0 was added by 0e3dbc01d53940fe10e5a5cfec15ede3e929c918 from Alan Cox. I can only find evidences that the drive only had troubles with spuruious completions by searching the mailing list. This entry needs to be verified and removed if it doesn't have other NCQ related problems.

* ahci: don't attach if ICH6 is in combined modeTejun Heo2007-12-07
| | | | | | | | | | | | ICH6 R/Ms share PCI ID between piix and ahci modes and we've been allowing ahci to attach regardless of how BIOS configured it. However, enabling AHCI mode when the controller is in combined mode can result in unexpected behavior. Don't attach if the controller is in combined mode.

* sata_mv: Warn about HPT RocketRAID BIOS treatment of "Legacy" drivesMark Lord2007-12-04
| | | | | | | | | | | | | | | | | The Highpoint RocketRAID boards using Marvell 7042 chips overwrite the 9th sector of attached drives at boot time, when those drives are configured as "Legacy" (the default) in the HighPoint BIOS. This kills GRUB, and probably other stuff. But it all happens *before* Linux is even loaded. So, for now we'll log a WARNING when such boards are detected, and advise users to configure BIOS "JBOD" volumes instead, which don't appear to suffer from this problem.

* sata_nv: don't use legacy DMA in ADMA mode (v3)Robert Hancock2007-12-04
| | | | | | | | | | | | We need to run any DMA command with result taskfile requested in ADMA mode when the port is in ADMA mode, otherwise it may try to use the legacy DMA engine in ADMA mode which is not allowed.

Also, fail any attempt to try and issue NCQ commands with result taskfile requested, since the hardware doesn't allow this.

* sata_mv: Fix broken Marvell 7042 support.Mark Lord2007-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | sata_mv: Fix broken Marvell 7042 support. The Marvell 7042 chip is more or less the same as the 6042 internally, but sports a PCIe bus. Despite having identical SATA cores, the 7042 does differ from its PCI bus counterparts in placment and layout of certain bus related registers. This patch fixes sata_mv to distinguish between the PCI bus registers of earlier chips, and the PCIe bus registers of the 7042. Specifically, move the offsets and bit patterns for the PCI/PCIe interrupt cause/mask registers into the struct mv_host_priv, as these values differ between the 6xxx and 7xxx series chips. This fixes the driver to not access reserved PCI addresses, and prevents the lockups reported in linux-2.6.24 with 7042 boards. Also add a new PCI ID for the Highpoint 2300 7042-based board that I'm using for testing this stuff here. Tested with Marvell 6081 + 7042 chips, on x86 & x86_64.

* libata: bump transfer chunk size if it's oddTejun Heo2007-11-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | None of the drives I have follows what the standard says about transfer chunk size. Of the four SATA and six PATA ATAPI devices tested, four ignore transfer chunk size completely and the ones which honor it don't behave according to the spec when it's odd. According to the spec, transfer chunk size can be odd if the amount of data to transfer equals or is smaller than the chunk size and the device can indicate the same odd number and transfer the whole thing at one go with a pad byte appended. However, in reality, none of the drives I have does that. They all indicate and transfer even number of bytes one byte shorter than the chunk size first; then indicate and transfer two bytes, which is clearly out of spec. In addition to unnecessary second PIO data phase, this also creates a weird problem when combined with SATA controllers which perform PIO via DMA. Some of these controllers use actualy number of bytes received to update DMA pointer so chunks which are sized 4n + 2 makes DMA pointer off by two bytes. This causes data corruption and buffer overruns. This patch rounds nbytes up to the nearest even number such that ATAPI devices don't split data transfer for the last odd byte. This shouldn't confuse controllers which depend on transfer chunk size as devices will report the rounded-up number, actually transfer that much and padding buffer is there to receive them.

* libata-scsi: be tolerant of 12-byte ATAPI commands in 16-byte CDBsMark Lord2007-11-18
| | | | | | | | | | | | | | | | | | Sebastian Kemper reported that issuing CD/DVD commands under libata is not fully compatible with ide-scsi. In particular, the GPCMD_SET_STREAMING was being rejected at the host level in some instances. The reason is that libata-scsi insists upon the cmd_len field exactly matching the SCSI opcode being issued, whereas ide-scsi tolerates 12-byte commands contained within a 16-byte (cmd_len) CDB. There doesn't seem to be a good reason for us to not be compatible there, so here is a patch to fix libata-scsi to permit SCSI opcodes so long as they fit within whatever size CDB is provided.
