2011-01-19drm/i915: Disable SSC for outputs other than LVDS or DPChris Wilson
For CRT and SDVO/HDMI, we need to use a normal, non-SSC, clock and so we must clear any enabling bits left-over from earlier outputs. And also seems to correct the LVDS panel on the Lenovo U160. However, at one point, it did cause an "ERROR failed to disable trancoder". So prolonged testing on top of Jesse's refactored and error-checking CRTC logic is desired. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-01-19drm/i915/bios: Change default clock source on PineView to use SSCBryan Freed
The i915 driver normally assumes the video bios has configured several of the LVDS panel registers, and it just inherits the values. If the vbios has not run, several of these will need to be setup. If these are not correct then although the panel looks ok, output from an HDMI encoder (eg, Chrontel CH7036) will be incorrect.

2011-01-19drm/i915: Honour LVDS sync polarity from EDIDBryan Freed
The i915 driver normally assumes the video bios has configured several of the LVDS panel registers, and it just inherits the values. If the vbios has not run, several of these will need to be setup. So we need to check that the LVDS sync polarity is correctly configured per any available modelines (e.g. EDID) and adjust if not, issuing a warning as we do.

2011-01-19drm/i915: allow 945 to control self refresh (CxSR) automaticallyAlexander Lam
I changed 945's self refresh to work without the need for the driver to enable/disable self refresh manually based on the idle state of the gpu. This is much better than enabling/disabling self refresh for various reasons, including staying in a lower power state for more time and avoiding the need for cpu cycles. This was originally done manually to workaround issues with the hardware hanging. However, since 944001201: drm/i915: enable low power render writes on GEN3 hardware, automatic CxSR seems stable.

2011-01-19drm/i915: Use PM QoS to prevent C-State starvation of gen3 GPUChris Wilson
945 class hardware has an interesting quirk in which the vblank interrupt is not raised if the CPU is in a low power state. (We also suspect that the memory bus is clocked to the CPU/c-state and not the GPU so there are secondary starvation issues.) In order to prevent the most obvious issue of the low of the vblank interrupt (stuttering compositing that only updates when the mouse is moving) is to install a PM QoS request to prevent low c-states whilst the GPU is active.

2011-01-17drm/radeon/kms: balance asic_reset functionsAlex Deucher
First, we were calling mc_stop() at the top of the function which turns off all MC (memory controller) clients, then checking if the GPU is idle. If it was idle we returned without re-enabling the MC clients which would lead to a blank screen, etc. This patch checks if the GPU is idle before calling mc_stop(). Second, if the reset failed, we were returning without re-enabling the MC clients. This patch re-enables the MC clients before returning regardless of whether the reset was successful or not.

2011-01-13drm/i915/execbuffer: Clear domains before beginning reloc processingChris Wilson
After reordering the sequence of relocating objects, commit 6fe4f1404, we can no longer rely on seeing all reloc targets prior to performing the relocation. As a result we were ignoring the need to flush objects from the render cache and invalidate the sampler caches, resulting in rendering glitches. So we need to clear the relocation domains earlier.

2011-01-13drm/i915/execbuffer: Reorder relocations to match new object orderChris Wilson
On the fault path, commit 6fe4f140 introduction a regression whereby it changed the sequence of the objects but continued to use the original ordering of relocation entries. The result was that incorrect GTT offsets were being fed into the execbuffer causing lots of misrendering and potential hangs.

2011-01-13drm/i915: Fix error handler to capture the first batch after the seqnoChris Wilson
Whilst we had no older batches on the active list, everything was fine. However, if the GPU is free running and the requests are only being reaped by the periodic retirer, than the current seqno may not be at the start of the list. In this case we need to select the first batch after the last seqno written by the gpu and not inclusive of the seqno. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-01-13drm/i915: Add a module option to override the use of SSCChris Wilson
In order to workaround the issue with LVDS not working on the Lenovo U160 apparently due to using the wrong SSC frequency, add an option to disable SSC.

... and not if the maximum is non-zero. This fixes the typo introduced in 47356eb6728501452 and preserves the backlight value from boot.

2011-01-11drm/i915/execbuffer: Reorder binding of objects to favour restrictionsChris Wilson
As the mappable portion of the aperture is always a small subset at the start of the GTT, it is allocated preferentially by drm_mm. This is useful in case we ever need to map an object later. However, if you have a large object that can consume the entire mappable region of the GTT this prevents the batchbuffer from fitting and so causing an error. Instead allocate all those that require a mapping up front in order to improve the likelihood of finding sufficient space to bind them. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2011-01-11drm/i915: If we hit OOM when allocating GTT pages, clear the apertureChris Wilson
Rather than evicting an object at random, which is unlikely to alleviate the memory pressure sufficient to allow us to continue, zap the entire aperture. That should give the system long enough to recover and reap some pages from the evicted objects, forestalling the allocation error for the new object.
