X-BeenThere: intel-gfx@lists.freedesktop.org X-Mailman-Version: 2.1.23 Precedence: list List-Id: Intel graphics driver community testing & development List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: daniel.vetter@intel.com Errors-To: intel-gfx-bounces@lists.freedesktop.org Sender: "Intel-gfx" X-Virus-Scanned: ClamAV using ClamSMTP To identify the HDCP capability of the display connected to CI systems, we need to add the hdcp capability probing in i915_display_info. This will also help to populate the HDCP capability of the CI systems to CI H/W logs maintained at https://intel-gfx-ci.01.org/hardware/. It will facilitate to determine the kms_content_protection behavior on a particular CI system. v2: Reused the intel_hdcp_info() in i915_hdcp_sink_capability_show(). [Ram] Shifted intel_hdcp_info() to the end of intel_dp_info. [Ram] v3: used seq_puts() instead of seq_pritnf().
