2015-12-22drm/i915: Break busywaiting for requests on pending signalsChris Wilson1-5/+8
The busywait in __i915_spin_request() does not respect pending signals and so may consume the entire timeslice for the task instead of returning to userspace to handle the signal. In the worst case this could cause a delay in signal processing of 20ms, which would be a noticeable jitter in cursor tracking. If a higher resolution signal was being used, for example to provide fairness of a server timeslices between clients, we could expect to detect some unfairness between clients (i.e. some windows not updating as fast as others). This issue was noticed when inspecting a report of poor interactivity resulting from excessively high __i915_spin_request usage.

2015-12-22drm/i915: Disable primary plane if we fail to reconstruct BIOS fb (v2)Matt Roper1-0/+15
If we fail to reconstruct the BIOS fb (e.g., because the FB is too large), we'll be left with plane state that indicates the primary plane is visible yet has a NULL fb. This mismatch causes problems later on (e.g., for the watermark code). Since we've failed to reconstruct the BIOS FB, the best solution is to just disable the primary plane and pretend the BIOS never had it enabled. v2: Add intel_pre_disable_primary() call (Maarten) Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Ville Syrjälä <ville.syrjala@intel.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: drm-intel-fixes@lists.freedesktop.org Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Reviewed-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1449171462-30763-2-git-send-email-matthew.d.roper@intel.com (cherry picked from commit 200757f5d7c6f7f7032a0a07bbb8c02a840bbf7d) Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2015-12-22drm/i915: Set the map-and-fenceable flag for preallocated objectsChris Wilson4-19/+27
As we mark the preallocated objects as bound, we should also flag them correctly as being map-and-fenceable (if appropriate!) so that later users do not get confused and try and rebind the pinned vma in order to get a map-and-fenceable binding.

2015-12-22drm/i915: Drop the broken cursor base==0 special casingVille Syrjälä1-17/+12
The cursor code tries to treat base==0 to mean disabled. That fails when the cursor bo gets bound at ggtt offset 0, and the user is left looking at an invisible cursor. We lose the disabled->disabled optimization, but that seems like something better handled at a slightly higher level.
