| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As these drivers' set_piomode() and set_dmamode() methods are almost identical, factor out the common hpt{37x|3x2n}_set_mode() function to be called by both of them, the same as in 'pata_hpt366' driver. This results in ~5% decrease in the 'pata_hpt37x' driver binary size and in ~4% decrease in the 'pata_hpt3x2n' driver binary size (as measured on x86-32).

* | | ahci: disable FPDMA auto-activate optimization on NVIDIA AHCIRobert Hancock2010-02-241-2/+10
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mike Cui reported that his system with an NVIDIA MCP79 (aka MCP7A) chipset stopped working with 2.6.32. The problem appears to be that 2.6.32 now enables the FPDMA auto-activate optimization in the ahci driver. The drive works fine with this enabled on an Intel AHCI so this appears to be a chipset bug. Since MCP79 is a fairly recent NVIDIA chipset and we don't have any info on whether any other NVIDIA chipsets have this issue, disable FPDMA AA optimization on all NVIDIA AHCI controllers for now.

* libata: retry FS IOs even if it has failed with AC_ERR_INVALIDTejun Heo2010-01-201-2/+3
| | | | | | | | | | | | | | | | | | | | libata currently doesn't retry if a command fails with AC_ERR_INVALID assuming that retrying won't get it any further even if retried. However, a failure may be classified as invalid through hardware glitch (incorrect reading of the error register or firmware bug) and there isn't whole lot to gain by not retrying as actually invalid commands will be failed immediately. Also, commands serving FS IOs are extremely unlikely to be invalid. Retry FS IOs even if it's marked invalid. Transient and incorrect invalid failure was seen while debugging firmware related issue on Samsung n130 on bko#14314. http://bugzilla.kernel.org/show_bug.cgi?id=14314 Signed-off-by: Tejun Heo <tj@kernel.org> Reported-by: Johannes Stezenbach <js@sig21.net> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

* sata_promise: don't classify overruns as HSM errorsMikael Pettersson2010-01-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | When sata_promise encounters an overrun or underrun error it translates that to a libata AC_ERR_HSM, causing a hard reset. Since over/under-runs were thought to be rare and transient, this action seemed reasonable. Unfortunately it turns out that the controller throws overrun errors when e.g. hal polls a CD or DVD writer containing blank media, causing long sequences of hard resets and retries before EH finally gives up. This patch updates sata_promise to classify over/under-runs as AC_ERR_OTHER instead. This allows libata EH and upper layers to retry or fail the operation as they see fit without the disruption caused by repeated hard resets. This fixes a problem using a DVD-RAM drive with sata_promise, reported by Thomas Schorpp. I also tested it on a DVD-RW drive.

| * ACPI: do not select ACPI_DOCK from ATA_ACPICarlos R. Mafra2009-12-241-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In March 2008 commit 0ac4a3c2fbbcadc3e96e4dc47d4ae802d66e6f67 ("ACPI: fix ATA_ACPI build") made CONFIG_ACPI_DOCK be selected by CONFIG_ATA_ACPI because of a build error when CONFIG_ATA_ACPI=y and CONFIG_ACPI_DOCK=m. However, in September 2008 commit 898b054f3eec5921320ae8614b5bdd7b07ea5b43 ("dock: make dock driver not a module") removed the possibility of having CONFIG_ACPI_DOCK=m and therefore there is no need for selecting it when CONFIG_ATA_ACPI=y. This makes the kernel ~5 Kb smaller for people who don't have a dock by allowing them to not have ACPI_DOCK compiled-in because of ATA_ACPI=y. Signed-off-by: Carlos R.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adev->dma_mode stores the transfer mode value not UDMA mode number so the condition in cmd64x_set_dmamode() is always true and the higher UDMA clock is always selected. This can potentially result in data corruption when UDMA33 device is used, when 40-wire cable is used or when the error recovery code decides to lower the device speed down.
