Merge tag 'drm-next-2020-10-15' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "Not a major amount of change, the i915 trees got split into display and gt trees to better facilitate higher level review, and there's a major refactoring of i915 GEM locking to use more core kernel concepts (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards get DC support, nouveau got a bump in displayport support with common code extraction from i915. Outside of drm this contains a couple of patches for hexint moduleparams which you've acked, and a virtio common code tree that you should also get via it's regular path.

+
+description:
+
+ The DCSS (display controller sub system) is used to source up to three
+ display buffers, compose them, and drive a display using HDMI 2.0a(with HDCP
+ 2.2) or MIPI-DSI. The DCSS is intended to support up to 4kp60 displays. HDR10
+ image processing capabilities are included to provide a solution capable of
+ driving next generation high dynamic range displays.
