From: Suraj Kandpal Date: Thu, 26 Oct 2023 12:11:40 +0000 (+0530) Subject: drm/i915/hdcp: Add more conditions to enable hdcp X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3b9bbd79627043a9fa9dd5b01bb29882663976e0;p=linux.git drm/i915/hdcp: Add more conditions to enable hdcp When we dock a monitor we end up with a enable and disable connector cycle but if hdcp content is running we get the userspace in enabled state and driver maintaining a undesired state which causes the content to stop playing and we only enable hdcp if the userspace state in desired. This patch fixes that. --v2 -Move code to intel_hdcp [Jani] Signed-off-by: Suraj Kandpal Reviewed-by: Ankit Nautiyal Signed-off-by: Ankit Nautiyal Link: https://patchwork.freedesktop.org/patch/msgid/20231026121139.987437-4-suraj.kandpal@intel.com --- diff --git a/drivers/gpu/drm/i915/display/intel_hdcp.c b/drivers/gpu/drm/i915/display/intel_hdcp.c index 44c0a93f3af82..39b3f7c0c77c9 100644 --- a/drivers/gpu/drm/i915/display/intel_hdcp.c +++ b/drivers/gpu/drm/i915/display/intel_hdcp.c @@ -2409,9 +2409,19 @@ void intel_hdcp_enable(struct intel_atomic_state *state, const struct intel_crtc_state *crtc_state, const struct drm_connector_state *conn_state) { - /* Enable hdcp if it's desired */ + struct intel_connector *connector = + to_intel_connector(conn_state->connector); + struct intel_hdcp *hdcp = &connector->hdcp; + + /* + * Enable hdcp if it's desired or if userspace is enabled and + * driver set its state to undesired + */ if (conn_state->content_protection == - DRM_MODE_CONTENT_PROTECTION_DESIRED) + DRM_MODE_CONTENT_PROTECTION_DESIRED || + (conn_state->content_protection == + DRM_MODE_CONTENT_PROTECTION_ENABLED && hdcp->value == + DRM_MODE_CONTENT_PROTECTION_UNDESIRED)) _intel_hdcp_enable(state, encoder, crtc_state, conn_state); }
