Till Gen11 HDCP HW block was part of DDI. Hence required changes in HW programming is handled here. As ME FW needs the transcoder detail on which HDCP is enabled on Gen12+ platform, we are populating the detail in hdcp_port_data. v2: _MMIO_TRANS is used [Lucas and Daniel] platform check is moved into the caller [Lucas] v3: platform check is moved into a macro [Shashank] v4: Few optimizations in the coding [Shashank] v5: Fixed alignment in macro definition in i915_reg.h [Shashank] unused variables "reg" is removed. v6: Configuring the transcoder at compute_config. transcoder is used instead of pipe in macros. Rebased. v7: transcoder is cached at intel_hdcp hdcp_port_data is configured with transcoder index asper ME FW. v8: s/trans/cpu_transcoder s/tc/cpu_transcoder Signed-off-by: Ramalingam C Reviewed-by: Shashank Sharma [v5] Acked-by: Jani Nikula --- drivers/gpu/drm/i915/display/intel_hdcp.c | 148 ++++++++++++++-------- drivers/gpu/drm/i915/display/intel_hdmi.c | 10 +- drivers/gpu/drm/i915/i915_reg.h | 124 ++++++++++++++++-- 3 files changed, 219 insertions(+), 63 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_hdcp.c b/drivers/gpu/drm/i915/display/intel_hdcp.c index 1e5548833e8f..e2084403db27 100644 --- a/drivers/gpu/drm/i915/display/intel_hdcp.c +++ b/drivers/gpu/drm/i915/display/intel_hdcp.c @@ -18,6 +18,7 @@ #include "intel_display_types.h" #include "intel_hdcp.h" #include "intel_sideband.h" +#include "intel_connector.h" #define KEY_LOAD_TRIES 5 #define ENCRYPT_STATUS_CHANGE_TIMEOUT_MS 50 @@ -105,24 +106,20 @@ bool intel_hdcp2_capable(struct intel_connector *connector) return capable;
