* Add i915 ioctls to configure pipes for vblank interrupt.Dave Airlie2006-06-24
| | | | | | | | | i915 vblanks can be generated from either pipe a or b, however a disabled pipe generates no interrupts. This change allows the X server to select which pipe generates vblank interrupts. From: Keith Packard <keith.packard@intel.com> via DRM CVS Signed-off-by: Dave Airlie <airlied@linux.ie>

* drm: radeon add a tcl state flush before accessing tcl vector spaceDave Airlie2006-06-24
| | | | | | | | | | | | Do a tcl state flush before accessing tcl vector space. This fixes some more problems with flickering (bug #6637). drm may not be appropriate place for this, since doing that flush there might both be overkill and insufficient in some cases. However, it's hard to figure out when that flush is needed, so this has to suffice. There does not seem to be a performance penalty associated with it.

| * [PATCH] libata: implement per-dev EH action mask eh_info->dev_action[]Tejun Heo2006-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the only per-dev EH action is REVALIDATE. EH used to exploit ehi->dev to do selective revalidation on a ATA bus. However, this is a bit hacky and makes it impossible to request selective revalidation from outside of EH or add another per-dev EH action. This patch adds per-dev EH action mask eh_info->dev_action[] and update EH to use this field for REVALIDATE. Note that per-dev actions can still be specified at port-level and it has the same effect of specifying the action for all devices on the port.

| * | [PATCH] libata: convert several bmdma-style controllers to new EH, take #3Tejun Heo2006-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert sata_sis, svw, uli and vsc drivers to new EH. All the drivers used to specify ATA_FLAG_SATA_RESET to tell libata to use SATA hardreset instead of SRST. This patch makes all the converted drivers use the standard bmdma error handler which uses both SRST and SATA hardreset. All the controllers should be able to perform SRST but still needs verification. If some of the controllers can't do SRST, it will be very easy to spot as it will show up during boot probing.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert sata_via to new EH. vt6420 used ATA_FLAG_SRST while vt6421 used ATA_FLAG_SATA_RESET. This difference seems to be an accident rather than intended. This patch makes both flavors use ata_bmdma_error_handler() which makes use of both SRST and SATA hardreset. This behavior change is intended and if it breaks anything, it should be very easy to spot. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>

There was no connection between the two hosts making it impossible to traverse all ports related to the controller. This patch adds host_set->next which points to the second host_set and makes ata_pci_remove_one() remove all associated host_sets. * On device removal, all ports hanging off the device are properly detached. Prior to this patch, ports on the first host_set weren't detached casuing oops on driver unloading. * On device removal, both host_sets are properly freed This will also be used by new power management code to suspend and resume all ports of a controller. host_set/port representation will be improved to handle legacy controllers better and this host_set linking will go away with it.

IRQ stays asserted even after SIEN is masked and IRQ is acked. Also, even while frozen, any SATA PHY event including hardreset raises SATA IRQ. Clearing SError seems to be the only way to deassert SATA IRQ. This patch makes sil_host_intr() clear SError on SATA IRQs and ignore SATA IRQs reported while frozen so that hardreset doesn't trigger hotplug event (which ends up hardresetting again). In such cases, the port still gets re-frozen to minimize the danger of screaming interrupts. This results in one nil EH repeat on controllers with broken SIEN but other than that does no harm.
