+Subject: drm/amd/display: Add HDR workaround for specific eDP
+
+From: Alex Hung <alex.hung@amd.com>
+
+commit 05af800704ee7187d9edd461ec90f3679b1c4aba upstream.
+
+[WHY & HOW]
+Some eDP panels suffer from flicking when HDR is enabled in KDE. This
+quirk works around it by skipping VSC that is incompatible with eDP
+panels.

+Subject: drm/amd/display: Fix system hang while resume with TBT monitor
+
+From: Tom Chung <chiahsuan.chung@amd.com>
+
+commit 52d4e3fb3d340447dcdac0e14ff21a764f326907 upstream.
+
+[Why]
+Connected with a Thunderbolt monitor and do the suspend and the system
+may hang while resume.
+
+The TBT monitor HPD will be triggered during the resume procedure
+and call the drm_client_modeset_probe() while
+struct drm_connector connector->dev->master is NULL.
+
+It will mess up the pipe topology after resume.
+
+[How]
+Skip the TBT monitor HPD during the resume procedure because we
+currently will probe the connectors after resume by default.

+Subject: drm/i915/gem: fix bitwise and logical AND mixup
+
+From: Jani Nikula <jani.nikula@intel.com>
+
+commit 394b52462020b6cceff1f7f47fdebd03589574f3 upstream.
+
+CONFIG_DRM_I915_USERFAULT_AUTOSUSPEND is an int, defaulting to 250. When
+the wakeref is non-zero, it's either -1 or a dynamically allocated
+pointer, depending on CONFIG_DRM_I915_DEBUG_RUNTIME_PM. It's likely that
+the code works by coincidence with the bitwise AND, but with
+CONFIG_DRM_I915_DEBUG_RUNTIME_PM=y, there's the off chance that the
+condition evaluates to false, and intel_wakeref_auto() doesn't get
+called. Switch to the intended logical AND.
+
+v2: Use != to avoid clang -Wconstant-logical-operand (Nathan)

+Subject: drm/sched: Add locking to drm_sched_entity_modify_sched
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Tvrtko Ursulin <tvrtko.ursulin@igalia.com>
+
+commit 4286cc2c953983d44d248c9de1c81d3a9643345c upstream.
+
+Without the locking amdgpu currently can race between
+amdgpu_ctx_set_entity_priority() (via drm_sched_entity_modify_sched()) and
+drm_sched_job_arm(), leading to the latter accesing potentially
+inconsitent entity->sched_list and entity->num_sched_list pair.
+
+v2:
+ * Improve commit message. (Philipp)
