* [PATCH] sata_sis: slave support on SiS965Uwe Koziolek2006-12-01
| | | | | | | | | | | | SiS965 and SiS180 chips must support slave mode, SiS965L and SiS964 chips must not support slave mode. SCR_STATUS for SATA ports in powerdown state fixed. Now returning 0x0113 instead of 0x0117. Avoids problem on detecting sata_sis controller. Signed-off-by: Uwe Koziolek <uwe.koziolek@gmx.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] ahci: preserve PORTS_IMPL over host resetsTejun Heo2006-12-01
| | | | | | | | | | Instead of writing 0xf blindly, preserve the content of write-once PORTS_IMPL register over host resets. This patch is taken from Jeff Garzik's AHCI init update patch. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] pdc202xx_old: Fix name clashes with PA-RISCAlan Cox2006-12-01
| | | | | | | | | | pdc_* functions are part of the global namespace for the PDC on PA-RISC systems and this means our choice of pdc_ causes collisions between the PDC globals and our static functions. Rename them to pdc202xx where they are for both 2024x and 2026x. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | Move dev->max_sectors configuration from ata_scsi_dev_config() to ata_dev_configure(). * more consistent. * allows LLDs to peek at the default dev->max_sectors value. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* [PATCH] libata: implement ATA_EHI_SETMODE and ATA_EHI_POST_SETMODETejun Heo2006-12-01
| | | | | | | | | | | | | | | | | | | | | | libata EH used to perform ata_set_mode() iff the EH session performed reset as indicated by ATA_EHI_DID_RESET. This is incorrect because ->dev_config() called by revalidation is allowed to modify transfer mode which ata_set_mode() should take care of. This patch implements the following two flags. * ATA_EHI_SETMODE: set during EH to schedule ata_set_mode(). Both new device attachment and revalidation set this flag. * ATA_EHI_POST_SETMODE: set while the device is revalidated after ata_set_mode(). Post-setmode revalidation is different from initial configuaration and EH revalidation in that ->dev_config() is not allowed tune transfer mode. LLD can use this flag to determine whether it's allowed to tune transfer mode. Note that POST_SETMODE ->dev_config() is guaranteed to be preceded by non-POST_SETMODE ->dev_config().

* [PATCH] libata: implement ATA_EHI_PRINTINFOTejun Heo2006-12-01
| | | | | | | | | | | | | Implement ehi flag ATA_EHI_PRINTINFO. This flag is set when device configuration needs to print out device info. This used to be handled by @print_info argument to ata_dev_configure() but LLDs also need to know about it in ->dev_config() callback. This patch replaces @print_info w/ ATA_EHI_PRINTINFO and make sata_sil print workaround messages only on the initial configuration.

* [PATCH] ahci: update ahci-vt8251 reset sequenceTejun Heo2006-12-01
| | | | | | | | | | | | | | | | | ahci-vt8251 * requires hardreset after PHY status change * doesn't clear BSY on signature FIS after hardreset * needs SError cleared for the port to operate after hardreset This patch implements ahci_vt8251_hardreset() and sets ATA_FLAG_HRST_TO_RESUME to handle the above behaviors.

* [PATCH] libata: handle 0xff status properlyTejun Heo2006-12-01
| | | | | | | | | | | | | | | | | | | | libata waits for !BSY even when the status register reports 0xff. This causes long boot delays when D8 isn't pulled down properly. This patch does the followings. * don't wait if status register is 0xff in all wait functions * make ata_busy_sleep() return 0 on success and -errno on failure. -ENODEV is returned on 0xff status and -EBUSY on other failures. * make ata_bus_softreset() succeed on 0xff status. 0xff status is not reset failure. It indicates no device. This removes unnecessary retries on such ports. Note that the code change assumes unoccupied port reporting 0xff status does not produce valid device signature.

* [PATCH] sata_nv ADMA/NCQ support for nForce4Robert Hancock2006-12-01
| | | | | | | | | | | | | | | | | | | | | This patch adds support for ADMA mode on NVIDIA nForce4 (CK804/MCP04) SATA controllers to the sata_nv driver. Benefits of ADMA mode include: - NCQ support - Reduced CPU overhead (controller DMAs command information from memory instead of them being pushed in by the CPU) - Full 64-bit DMA support ADMA mode is enabled by default in this version. To disable it, set the module parameter adma_enabled=0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | JMicron AHCI controllers set PORT_IRQ_IF_ERR on device errors. The IRQ status bit indicates interface error or protocol mismatch and ahci driver interprets it into AC_ERR_ATA_BUS. So, whenever an ATAPI device raises check condition, ahci interprets it as ATA bus error and thus resets it which, in turn, raises check condition thus creating a reset loop and rendering the device unuseable. This patch makes JMB controllers ignore PORT_IRQ_IF_ERR when interpreting error condition. Signed-off-by: Tejun Heo <htejun@gmail.com> Cc: Justin Tsai <justin@jmicron.com>
