| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | apic.h does not get included on UP compiles. That way the APICTIMER_STOPS_ON_C3 is not there and UP boxen have no support for timer broadcasting. This was never noticed, because the lapic timer is only used for profiling on UP.

This will need to be updated later to provide a firmware hook to handle system suspend with an alarm pending. Len notes that "Eventually we may bundle ACPI/PNP/PNPACPI..." but if/when that happens, ACPI can simplify this without my help. And until it does, the separate patch creating a platform_device (on all X86_PC systems, even without ACPI) will be needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows drm to populate an agpgart structure with pages of its own. It's needed for the new drm memory manager which dynamically flips pages in and out of AGP. The patch modifies the generic functions as well as the intel agp driver. The intel drm driver is currently the only one supporting the new memory manager. Other agp drivers may need some minor fixing up once they have a corresponding memory manager enabled drm driver. AGP memory types >= AGP_USER_TYPES are not populated by the agpgart driver, but the drm is expected to do that, as well as taking care of cache- and tlb flushing when needed. It's not possible to request these types from user space using agpgart ioctls. The Intel driver also gets a new memory type for pages that can be bound cached to the intel GTT.

This patch: Convert policy->lock to rwsem and move it to per_cpu area. This rwsem will protect against both changing/accessing policy related parameters and CPU hot plug/unplug.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This modifies drivers/ata/sata_vsc.c to only set the cache line size to 0x80 if the default value is zero. Apparently zero isn't allowed due to a bug in the chip, but I've found performance is much better with the (non-zero) default instead of 0x80.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ADMA-capable controllers provide a bit in the status register that appears to indicate that the controller detected an SError condition. Update sata_nv to detect this and trigger error handling in order to handle the fault. Signed-off-by: Robert Hancock <hancockr@shaw.ca> Signed-off-by: Jeff Garzik <jeff@garzik.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hald media changed polling does really confuse things. Noone knows why the delays are needed, but they give us access to the CD. An udelay(50) will give reliable access to the drive, but there is still one (or more) EH reset. The drive works without EH resets with udelay(100). Signed-off-by: Olaf Hering <olaf@aepfle.de> Signed-off-by: Jeff Garzik <jeff@garzik.org>

Set ATA_TFLAG_ISADDR | ATA_TFLAG_DEVICE for IDENTIFY such that whole TF is cleared when reading ID data.

* | | | sata_promise: new EH conversion for 20619 chips, take 2Mikael Pettersson2007-02-15

Also used a CD-RW drive to test reading and writing CDs. Signed-off-by: Mikael Pettersson <mikpe@it.uu.se> Signed-off-by: Jeff Garzik <jeff@garzik.org>
