drm: Fix GETCONNECTOR regression

Fix that again. v2: Fix up the error path handling when copy_to_user for the modes failes (Dhinakaran).

drm/vc4: Fix OOPSes from trying to cache a partially constructed BO.

commit ca39b449f6d03e8235969f12f5dd25b8eb4304d6 upstream. If a CMA allocation failed, the partially constructed BO would be unreferenced through the normal path, and we might choose to put it in the BO cache. If we then reused it before it expired from the cache, the kernel would OOPS. Signed-off-by: Eric Anholt Fixes: c826a6e10644 ("drm/vc4: Add a BO cache.")

drm/i915: Do not sync RCU during shrinking

2017-06-24T05:06:15+00:00

commit 4681ee21d62cfed4364e09ec50ee8e88185dd628 upstream. Due to the complex dependencies between workqueues and RCU, which are not easily detected by lockdep, do not synchronize RCU during shrinking. On low-on-memory systems (mem=1G for example), the RCU sync leads to all system workqueus freezing and unrelated lockdep splats are displayed according to reports. GIT bisecting done by J. R. Okajima points to the commit where RCU syncing was extended. RCU sync gains us very little benefit in real life scenarios where the amount of memory used by object backing storage is dominant over the metadata under RCU, so drop it altogether. " Yeeeaah, if core could just, go ahead and reclaim RCU queues, that'd be great. " - Chris Wilson, 2016 (0eafec6d3244) v2: More information to commit message. v3: Remove "grep _rcu_" escapee from i915_gem_shrink_all (Andrea) Fixes: c053b5a506d3 ("drm/i915: Don't call synchronize_rcu_expedited under struct_mutex") Suggested-by: Chris Wilson Reported-by: J.

drm/i915: Fix scaling check for 90/270 degree plane rotation

2017-06-24T05:06:15+00:00

commit 9a775e0308b575e3a17c66a586ed049b07f48199 upstream. Starting from commit b63a16f6cd89 ("drm/i915: Compute display surface offset in the plane check hook for SKL+") we've already rotated the src coordinates by 270 degrees by the time we check if a scaler is needed or not, so we must not account for the rotation a second time. Previously we did these steps in the opposite order and hence the scaler check had to deal with rotation itself. The double rotation handling causes us to enable a scaler pretty much every time 90/270 degree plane rotation is requested, leading to fuzzier fonts and whatnot. v2: s/unsigned/unsigned int/ to appease checkpatch v3: s/DRM_ROTATE_0/DRM_MODE_ROTATE_0/ Cc: Tvrtko Ursulin Reported-by: Tvrtko Ursulin Tested-by: Tvrtko Ursulin Fixes: b63a16f6cd89 ("drm/i915: Compute display surface offset in the plane check hook for SKL+") Signed-off-by: Ville Syrjälä Link: http://patchwork.freedesktop.org/patch/msgid/20170331180056.14086-2-ville.syrjala@linux.intel.com Reviewed-by: Maarten Lankhorst (cherry picked from commit d96a7d2adb040a67e163a82dad6316f9f572498a) Signed-off-by: Jani Nikula Link: http://patchwork.freedesktop.org/patch/msgid/20170608144002.1605-1-ville.syrjala@linux.intel.com Signed-off-by: Greg Kroah-Hartman
