* [PATCH] libata: implement ATA_EHI_PRINTINFOTejun Heo2006-12-014-11/+19
| | | | | | | | | | | | | 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 Heo2006-12-011-2/+76
| | | | | | | | | | | | | | | | | 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. This fixes EH including hotplug on vt8251. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | ata_irq_on() isn't used outside of libata core layer. The function is TF/SFF interface specific but currently used by core path with some hack too.

* [PATCH] libata: handle 0xff status properlyTejun Heo2006-12-011-12/+18
| | | | | | | | | | | | | | | | | | | | 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 Hancock2006-12-012-12/+924
| | | | | | | | | | | | | | | | | | | | | 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.

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>
