Adding a debugfs entry for detecting the valid HDCP sinks to perform kms_content_protection. In case of dummy HDMI/DP sinks(EDID whisperers without any parsers) IGT will skip the HDCP test on that connector instead of failing it. Hence false alarm are avoided. For serving above purpose this series has pulled out few changes from "Implement HDCP2.2" series under review at https://patchwork.freedesktop.org/series/38254/ "drm/i915: hdcp_check_link only on CP_IRQ" is just a improvement patch for HDCP1.4. Already received the reviewed-by from Sean Paul. v3: Adding the debugfs file "i915_hdcp_sink_capability" under the connector director ../dri/0/<connector-name>/ Ramalingam C (4): drm/i915: Pullout the bksv read and validation drm/i915: Detect the hdcp capability of sink and src drm/i915: hdcp_check_link only on CP_IRQ drm/i915/debugfs: hdcp capability of a sink drivers/gpu/drm/i915/i915_debugfs.c | 29 +++++++++++ drivers/gpu/drm/i915/intel_dp.c | 10 ++-- drivers/gpu/drm/i915/intel_drv.h | 1 + drivers/gpu/drm/i915/intel_hdcp.c | 95 +++++++++++++++++++++++++------------ drivers/gpu/drm/i915/intel_hdmi.c | 16 ++++++- 5 files changed, 115 insertions(+), 36 deletions(-) -- 2.7.4 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
