2009-07-15drm/radeon/kms: block RN50 from using 3D engine.Dave Airlie
RN50/ES1000 is a cut-down rv100 chip used in the server market. The 3D engine on these is either not there or unverified so refuse any attempt to configure registers on it. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: fix VRAM sizing like DDX does it.Dave Airlie
Doing this like the DDX seems like the most sure fire way to avoid having to reinvent it slowly and painfully. At the moment we keep getting things wrong with aper vs vram, so we know the DDX does it right. booted on PCI r100, PCIE rv370, IGP rs400. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/ttm/radeon: add dma32 support.Dave Airlie
This add support for using dma32 memory on gpus that really need it. Currently IGPs are left without DMA32 but we might need to change that unless we can fix rs690. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon: Endianness fixes for radeondrmfb.Michel Dänzer
For now handle it via r/g/b offsets and disallow 16 bpp modes on big endian machines. Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: don't swap PCIEGART PTEs in VRAM.Dave Airlie
On powerpc, since we aren't using any hw swappers, this will get flipped around by default in hw. tested on a G5 + rv515. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: drop zero length CS indirect buffers.Dave Airlie
If userspace sends a zero length IB, it really shouldn't have bothered so EINVAL it. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: fix vram vs aper size check.Dave Airlie
Fix this to be correct like the DDX code, looks like a typo on transfer to the kernel. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: get lvds info for DIG LVTMA and UNIPHY encodersAlex Deucher
Noticed by Rafał Miłecki on dri-devel. On r6xx/r7xx hardware, laptop panels can be driven by KLDSCP_LVTMA or UNIPHY. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: fix quirk for MSI laptopAlex Deucher
The line mux for the connector in the bios tables is used for enumerating drm connectors. Since this laptop has a quirk where the same line much is listed for both VGA and LVDS, the connectors get combined. Setting the line mux on LVDS to an unused value prevents both encoders from being combined into the same connector. This should fix bko bug 13720.

2009-07-15ttm: Fix caching mode selection.Thomas Hellstrom
A bug caused a new caching state to be selected on each buffer object validation regardless of the current caching state. Moreover, a caching state could be selected that wasn't supported by the memory type. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-07-15drm/radeon: fix support for vline relocations.Dave Airlie
Userspace sends us a special relocation type to sync video/exa to vlines to avoid tearing, this deals with the relocation in the kernel, it picks the correct crtc and avoids issues where crtcs are disabled. This version also parses the wait until to make sure it isn't trying to do anything evil. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: respect TOM on rs100->rs480 IGP variants.Dave Airlie
Normally we are free to place VRAM where we want in the GPUs memory address space, however on IGP chips the VRAM is actual RAM, and no special translation or aperture is used inside the GPU MC. So when you move the VRAM aperture away from the TOM register, you actually move it into main memory and can trash things quite badly. This commit makes the code respect the TOM location for MC_FB_LOCATION. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: set crtc and cursor offsets correctly on legacy chips.Dave Airlie
The crtc and cursor offsets on the legacy chips are offset from DISPLAY_BASE_ADDR. The code worked if display base addr was at 0, but otherwise falls to pieces. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: remove IB flushing trick.Dave Airlie
If there is a problem then this is hiding it, we shouldn't ever need to flush the IB. Either the buffers are: WB - caching just works. WC - no need to do explicit flush, the MB + readback will do it Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: mmio base/size should be resource_size_t.Dave Airlie
Unsigned long is incorrect for 64-bit resources on 32-bit hw. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-07-15drm/radeon/kms: fix some GART table entry bugs.Dave Airlie

2009-07-15fb/intelfb: conflict with DRM_I915 and hide by defaultJesse Barnes
Users get confused by this driver. It's really a special purpose embedded driver, and causes a lot of problems if enabled. So hide it under EMBEDDED by default, and make sure it doesn't get enabled with the i915 DRM driver. Dave, I'm hoping you can feed this to Linus through your tree. It's appropriate for 2.6.31 I think. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@linux.ie>

2009-07-15drm/via: Fix vblank IRQ on VIA hardware.Simon Farnsworth

2009-07-14libata: implement and use HORKAGE_NOSETXFER, take#2Tejun Heo
PIONEER DVD-RW DVRTD08 times out SETXFER if no media is present. The device is SATA and simply skipping SETXFER works around the problem. Implement ATA_HORKAGE_NOSETXFER and apply it to the device. Reported by Moritz Rigler in the following thread. http://thread.gmane.org/gmane.linux.ide/36790 and by Lars in bko#9540. Updated to whine and ignore NOSETXFER if PATA component is detected as suggested by Alan Cox.

2009-07-14libata: fix follow-up SRST failure pathTejun Heo
ata_eh_reset() was missing error return handling after follow-up SRST allowing EH to continue the normal probing path after reset failure.
