      drm/i915/hdmi: Detect HDMI 2.0 monitors using multiple EDID capabilities · 47164e0b
      Clint Taylor authored
      HDMI 2.0 monitors may not support SCDC and still be able to accept VICs
      above 63. Use multiple EDID capbilities to determine if the SINK is
      actually an HDMI 2.0 device. The QD980B HDMI 2.0 Analyzer generates unique
      EDIDs during CTS tests that don't contain a HDMI Forum VSDB if the block is
      not used during the test. The current HDMI AVI infoframe code only uses the
      SCDC supported information in the HDMI Forum VSDB to determine if the sink
      is HDMI 2.0. This patch adds a check for YCbCr420 present in the EDID
      supported formats as well as the existing SCDC supported check.
      
      HDMI 2.0 CTS HF1-51 test fails on the QD980B.
      
      V2: Make check for display_info->color formats == YCbCR420 and SCDC

      dma-buf: Update reservation shared_count after adding the new fence · a590d0fd
      Chris Wilson authored
      We need to serialise the addition of a new fence into the shared list
      such that the fence is visible before we claim it is there. Otherwise a
      concurrent reader of the shared fence list will see an uninitialised
      fence slot before it is set.

      drm/syncobj: Avoid kmalloc(GFP_KERNEL) under spinlock · 4fb2c933
      Chunming Zhou authored
      drivers/gpu/drm/drm_syncobj.c:202:4-14: ERROR: function drm_syncobj_find_signal_pt_for_point called on line 390 inside lock on line 389 but uses GFP_KERNEL
      
        Find functions that refer to GFP_KERNEL but are called with locks held.
      
      Generated by: scripts/coccinelle/locks/call_kern.cocci
      
      v2:
      syncobj->timeline still needs protect.
      
      v3:
      use a global signaled fence instead of re-allocation.
      
      v4:
      Don't need moving lock.
      Don't expose func.
      
      v5:
      rename func and directly return.
      
      Tested by: syncobj_wait and ./deqp-vk -n dEQP-VK.*semaphore* with
      lock debug kernel options enabled.
