drm/radeon/kms: fix DDIA enable on some rs690 systems

2011-10-03T18:41:03+00:00

commit fdfc61594e6de21c23f955818ef78bcab9bafe40 upstream. DVOOutputControl checks the value of of bios scratch reg 3 on some tables and assumes the encoder is already enabled if the DFP2_ACTIVE bit is set. Clear that bit so the table sets the DDIA enable bit properly. Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon/kms: Make GPU/CPU page size handling consistent in blit code (v2)

2011-10-03T18:40:33+00:00

commit 003cefe0c238e683a29d2207dba945b508cd45b7 upstream. The BO blit code inconsistenly handled the page size. This wasn't an issue on system with 4k pages since the GPU's page size is 4k as well. Switch the driver blit callbacks to take num pages in GPU page units. Fixes lemote mipsel systems using AMD rs780/rs880 chipsets. v2: incorporate suggestions from Michel.

drm/radeon: Don't read from CP ring write pointer registers.

2011-10-03T18:40:29+00:00

commit 87463ff83bcda210d8f0ae440bd64d1548f852e7 upstream. Apparently this doesn't always work reliably, e.g. at resume time. Just initialize to 0, so the ring is considered empty. Tested with hibernation on Sumo and Cayman cards. Should fix https://bugs.launchpad.net/ubuntu/+source/linux/+bug/820746/ .

drm/nouveau: properly handle allocation failure in nouveau_sgdma_populate

2011-10-03T18:40:14+00:00

commit 17c8b960930da3599e47801a54ac0ea1070545d2 upstream. Not cleaning after alloc failure would result in crash on destroy, because nouveau_sgdma_clear assumes "ttm_alloced" to be not null when "pages" is not null.

drm/radeon/kms: make sure pci max read request size is valid on evergreen+ (v2)

2011-10-03T18:40:04+00:00

commit d054ac16eeb658bccadb06b12c39cee22243b10f upstream. If the bios or OS sets the pci max read request size to 0 or an invalid value (6,7), it can result in a hang or slowdown. Check and set it to something sane if it's invalid.

drm/radeon/kms: set a default max_pixel_clock

commit 9adceaa5b3d2480e2252c4a7f9c4bd7d66b8c4a2 upstream. On some Power rv100 cards, we have no ATY OF table, but we have no combios table either, and hence we refuse all modes on VGA-0 since we end up with a 0 max pixel clock.
