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 --v2 -call intel_hdcp_prepare_stream instead of intel_hdcp_required_stream in the beginning [Ankit] -replace intel_connector argument with intel_encoder [Jani] Signed-off-by: Suraj Kandpal <suraj.kandpal@xxxxxxxxx> Suraj Kandpal (2): drm/i915/hdcp: add intel_atomic_state argument to hdcp_enable function drm/i915/hdcp: Fix modeset locking issue in hdcp mst drivers/gpu/drm/i915/display/intel_ddi.c | 4 +- drivers/gpu/drm/i915/display/intel_dp_mst.c | 4 +- drivers/gpu/drm/i915/display/intel_hdcp.c | 55 ++++++++++----------- drivers/gpu/drm/i915/display/intel_hdcp.h | 6 ++- 4 files changed, 32 insertions(+), 37 deletions(-) -- 2.25.1
