hpt366: fix HPT370 DMA timeouts

2009-05-02T17:24:24Z

upstream commit: c018f1ee5cf81e58b93d9e93a2ee39cad13dc1ac The big driver change in 2.4.19-rc1 introduced a regression for many HPT370[A] chips -- DMA stopped to work completely, only causing endless timeouts... The culprit has been identified (at last!): it turned to be the code resetting the DMA state machine before each transfer. Stop doing it now as this counter- measure has clearly caused more harm than good. This should fix the kernel.org bug #7703.

ide-iops: fix odd-length ATAPI PIO transfers

2009-03-17T00:53:03Z

commit a509538d4fb4f99cdf0a095213d57cc3b2347615 upstream. Commit 9567b349f7e7dd7e2483db99ee8e4a6fe0caca38 (ide: merge ->atapi_*put_bytes and ->ata_*put_data methods) introduced a regression WRT the odd-length ATAPI PIO transfers -- the final word didn't get written (causing command timeouts).

it821x: Add ultra_mask quirk for Vortex86SX

2009-02-02T16:28:08Z

commit b94b898f3107046b5c97c556e23529283ea5eadd upstream. On Vortex86SX with IDE controller revision 0x11 ultra DMA must be disabled. This patch was tested by DMP and seems to work. It is a cleaned up version of their older Kernel patch: http://www.dmp.com.tw/tech/vortex86sx/patch-2.6.24-DMP.gz Tested-by: Shawn Lin Signed-off-by: Brandon Philips Cc: Alan Cox Signed-off-by: Bartlomiej Zolnierkiewicz Signed-off-by: Greg Kroah-Hartman

IDE: Fix platform device registration in Swarm IDE driver (v2)

2008-10-05T16:23:28Z

The Swarm IDE driver uses a release method which is defined in the driver itself thus potentially oopsable. The simple fix would be to just leak the device but this patch goes the full length and moves the entire handling of the platform device in the platform code and retains only the platform driver code in drivers/ide/mips/swarm.c.

ide-dma: fix ide_build_dmatable() for TRM290

2008-10-05T16:23:27Z

Apparently, 'xcount' being 0 does not mean 0 bytes for TRM290; it means 4 bytes, judging from the code immediately preceding this check. So, we must never try to "split" the PRD for TRM290. This is probably never hit anyway -- with the DMA buffers aligned to at least 512 bytes and ATAPI DMA not being used for non block I/O commands...

ide-cd: temporary tray close fix

2008-10-05T16:23:27Z

This one fixes http://bugzilla.kernel.org/show_bug.cgi?id=11602. A more generic fix for drives which cannot autoclose tray will follow.

ide: note that IDE generic may prevent other drivers from attaching

2008-09-27T17:32:17Z

Enabling IDE generic may prevent ATA controllers located on legacy ports from being attached to more proper driver or can prevent other controllers which share the IRQ from working. Note it in the help message.
