2014-01-23drm/nouveau: make vga_switcheroo code depend on VGA_SWITCHEROOJeff Mahoney
Commit 8116188fdef594 ("nouveau/acpi: hook up to the MXM method for mux switching.") broke the build on non-x86 architectures due to the new dependency on MXM and MXM being an x86 platform driver. It built previously since the vga switcheroo registration routines were zereod out on !X86. The code was built in but unused. This patch makes all of the DSM code depend on CONFIG_VGA_SWITCHEROO, allowing it to build on non-x86 and shrinking the module size as well.

2014-01-22drm/i915: Repeat evictions whilst pageflip completions are outstandingChris Wilson
Since an old pageflip will keep its scanout buffer object pinned until it has executed its unpin task on the common workqueue, we can clog up our GGTT with stale pinned objects. As we cannot flush those workqueues without dropping our locks, we have to resort to falling back to userspace and telling them to repeat the operation in order to have a chance to run our workqueues and free up the required memory. If we fail, then we are forced to report ENOSPC back to userspace causing the operation to fail and best-case scenario is that it introduces temporary corruption.

2014-01-22drm/i915: Wait for completion of pending flips when starved of fencesChris Wilson
On older generations (gen2, gen3) the GPU requires fences for many operations, such as blits. The display hardware also requires fences for scanouts and this leads to a situation where an arbitrary number of fences may be pinned by old scanouts following a pageflip but before we have executed the unpin workqueue. This is unpredictable by userspace and leads to random EDEADLK when submitting an otherwise benign execbuffer. However, we can detect when we have an outstanding flip and so cause userspace to wait upon their completion before finally declaring that the system is starved of fences. This is really no worse than forcing the GPU to stall waiting for older execbuffer to retire and release their fences before we can reallocate them for the next execbuffer. v2: move the test for a pending fb unpin to a common routine for later reuse during eviction Reported-and-tested-by: dimon@gmx.net Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=73696 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Jon Bloomfield <jon.bloomfield@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-01-22drm/i915: don't disable DP port after a failed link trainingImre Deak
Atm after a failed link training we disable the DP port. This can happen during a modeset-enable or a DP link re-establishment. The latter can be a problem and we shouldn't disable the DP port, see the previous patch for the reasoning. In the former case the right thing would be to disable the DP port, but also the rest of the pipe. As a stop-gap solution leave the DP port enabled in both cases. It is an improvement on its own (avoiding HW lock ups) and the proper solution for the first case requires a bigger change, so let's keep that on the TODO list. v2: - fix explanation of change impact (Chris) Suggested-by: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Imre Deak <imre.deak@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2014-01-22drm/i915: don't disable the DP port if the link is lostImre Deak
Currently if the DP link is lost (either because of a hot unplug, or failed link status check) we disable the DP port, but leave the rest of the pipe running. This is incompatible with the modeset disabling sequence of some platforms/configurations. At least this is the case for DP ports on the CPU as opposed to PCH. Atm we'll also get a warning when we do a modeset disable after the above link lost event, since we expect the DP port to be enabled at this point (see the bugzilla ticket for the related dmesg). Note that with this patch we'll still end up disabling the port, thanks to the HPD uevent and subsequent modeset disable. See also the next patch fixing the other half of this issue.

2014-01-22drm/i915: Eliminate lots of WARNs when there's no backlight presentVille Syrjälä
My 855gm doesn't register the intel backlight but it still ends up calling the backlight code to enable/disable the backlight via the LVDS code. This leads to some WARNs due to backlight.max being 0. Let's have intel_panel_enable_backlight() and intel_panel_disable_backlight() check whether there's a backlight present or not. Also move the backlight.present check from asle_set_backlight() into intel_panel_set_backlight() for some extra symmetry.

2014-01-21drm/gem: Always initialize the gem object in object_initDaniel Vetter
At least drm/i915 expects that the obj->dev pointer is set even in failure paths. Specifically when the shmem initialization fails we call i915_gem_object_free which needs to deref obj->base.dev to get at the slab pointer in the device private structure. And the shmem allocation can easily fail when userspace is hitting open file limits. Doing the structure init even when the shmem file allocation fails prevents this Oops. This is a regression from commit 89c8233f82d9c8af5b20e72e4a185a38a7d3c50b Author: David Herrmann <dh.herrmann@gmail.com> Date: Thu Jul 11 11:56:32 2013 +0200 drm/gem: simplify object initialization v2: Add regression note which Chris supplied.

2014-01-20drm/radeon/dpm: disable mclk switching on desktop RV770Alex Deucher
Mclk switching doesn't seem to work reliably on these cards. Most RV770 boards specify the same mclk for all performance levels anyway so in most cases, this has no affect.
