Subject: [Intel-gfx] [PATCH 0/2] Fix modeset locking issue in HDCP MST
Date: Thu, 11 May 2023 11:27:03 +0530 [thread overview]
Message-ID: <20230511055705.611809-1-suraj.kandpal@intel.com> (raw)
HDCP MST scenario sees modeset locking issue ever since
topology_state was added to drm_atomic_state and all modeset
locks were being taken for us causing a locking issue to occur
when we iterate over connectors to assign vcpi id, the fix
being to pass acquire_ctx to drm_modeset_lock
