On every hdcp revocation check request SRM is read from fw file /lib/firmware/display_hdcp_srm.bin SRM table is parsed and stored at drm_hdcp.c, with functions exported for the services for revocation check from drivers (which implements the HDCP authentication) This patch handles the HDCP1.4 and 2.2 versions of SRM table. v2: moved the uAPI to request_firmware_direct() [Daniel] v3: kdoc added. [Daniel] srm_header unified and bit field definitions are removed. [Daniel] locking improved. [Daniel] vrl length violation is fixed. [Daniel] v4: s/__swab16/be16_to_cpu [Daniel] be24_to_cpu is done through a global func [Daniel] Unused variables are removed. [Daniel] unchecked return values are dropped from static funcs [Daniel] Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Acked-by: Satyeshwar Singh <satyeshwar.singh@intel.com> Reviewed-by: Daniel Vetter <daniel@ffwll.ch> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20190507162745.25600-5-ramalingam.c@intel.com |
