2016-09-07drm/i915: Make HWS_NEEDS_PHYSICAL the exceptionCarlos Santa
Make the .hws_needs_physical the exception by switching the flag on earlier platforms since they are fewer to support. Remove the flag on later GPUs hardware since they all use GTT hws by default. Switch the logic as well in the driver to reflect this change Signed-off-by: Carlos Santa <carlos.santa@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>

2016-09-07Revert "drm/i915: Check live status before reading edid"David Weinehall
This reverts commit 237ed86c693d8a8e4db476976aeb30df4deac74b. Our current implementation of live status check (repeat 9 times with 10ms delays between each attempt as a workaround for buggy displays) imposes a rather serious penalty, time wise, on intel_hdmi_detect(). Since we we already skip live status checks on platforms before gen 7, and since we seem to have coped quite well before the live status check was introduced for newer platforms too, the previous behaviour is probably preferable, at least unless someone can point to a use-case that the live status check improves (apart from "Bspec says so".)

2016-09-07drm/i915/skl: Don't try to update plane watermarks if they haven't changedLyude
i915 sometimes needs to disable planes in the middle of an atomic commit, and then reenable them later in the same commit. Because of this, we can't make the assumption that the state of the plane actually changed. Since the state of the plane hasn't actually changed, neither have it's watermarks. And if the watermarks hasn't changed then we haven't populated skl_results with anything, which means we'll end up zeroing out a plane's watermarks in the middle of the atomic commit without restoring them later. Simple reproduction recipe: - Get a SKL laptop, launch any kind of X session - Get two extra monitors - Keep hotplugging both displays (so that the display configuration jumps from 1 active pipe to 3 active pipes and back) - Eventually underrun Changes since v1: - Fix incorrect use of "it's" Changes since v2: - Add reproduction recipe Signed-off-by: Lyude <cpaul@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Fixes: 62e0fb880123 ("drm/i915/skl: Update plane watermarks atomically during plane updates") Signed-off-by: Lyude <cpaul@redhat.com> Testcase: kms_plane Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1472488288-27280-1-git-send-email-cpaul@redhat.com Cc: drm-intel-fixes@lists.freedesktop.org
2016-09-06drm/i915: Remove 64b mmio write vfuncsChris Wilson
We don't have safe 64-bit mmio writes as they are really split into 2x32-bit writes. This tearing is dangerous as the hardware *will* operate on the intermediate value, requiring great care when assigning. (See, for example, i965_write_fence_reg.) As such we don't currently use them and strongly advise not to us them.

2016-09-02drm/i915: Drop mutex around clearing error stateChris Wilson
The error state itself is guarded by a spinlock (admittedly even that is overkill for a single pointer!) and doesn't require us to take the struct_mutex in the debugfs/sysfs interface. Removing the struct_mutex removes one more potential blockage when trying to debug a deadlock.

Use atomic type and operands for dev_priv->mm.bsd_engine_dispatch_index to avoid one struct_mutex locking scenario.
