2016-09-07drm/i915: Introduce GEN4_FEATURES for device infoCarlos Santa
Introducing a GEN4_FEATURES macro to simplify the struct definitions by platforms given that most of the features are common. Inspired by the GEN7_FEATURES macro done by Ben W. and others.

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. Go one step further and remove the 64-bit write vfuncs. v2: Add some more details to the comment about why WRITE64 is absent, and why you need to think twice before using READ64.

2016-08-27drm/i915: Make for_each_engine_masked() more compact and quickerChris Wilson
Rather than walk the full array of engines checking whether each is in the mask in turn, we can use the mask to jump to the right engines. This should quicker for a sparse array of engines or mask, whilst generating smaller code: text data bss dec hex filename 1251010 4579 800 1256389 132bc5 drivers/gpu/drm/i915/i915.ko 1250530 4579 800 1255909 1329e5 drivers/gpu/drm/i915/i915.ko The downside is that we have to pass in a temporary, alas no C99 iterators yet. [P.S. Joonas doesn't like having to pass extra temporaries into the macro, and even less that I called them tmp. As yet, we haven't found a macro that avoids passing in a temporary that is smaller. We probably will get C99 iterators first!] Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Reviewed-by: Mika Kuoppala <mika.kuoppala@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20160827075401.16470-2-chris@chris-wilson.co.uk
2016-08-27drm/i915: Tidy reporting busy status during i915_gem_retire_requests()Chris Wilson
As we know by inspection whether any engine is still busy as we retire all the requests, we can pass that information back via return value rather than check again afterwards. v2: A little more polish missed in patch splitting Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Reviewed-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20160827075401.16470-1-chris@chris-wilson.co.uk
2016-08-26drm/i915: Allow the user to pass a context to any ringChris Wilson
With full-ppgtt, we want the user to have full control over their memory layout, with a separate instance per context. Forcing them to use a shared memory layout for !RCS not only duplicates the amount of work we have to do, but also defeats the memory segregation on offer.
