video/hdmi: Add Unpack only function for DRM infoframe

2020-05-14T10:50:43Z

It adds an unpack only function for DRM infoframe for dynamic range and mastering infoframe readout. It unpacks the information data block contained in the binary buffer into a structured frame of the HDMI Dynamic Range and Mastering (DRM) information frame. In contrast to hdmi_drm_infoframe_unpack() function, it does not verify a checksum. It can be used for unpacking a DP HDR Metadata Infoframe SDP case. DP HDR Metadata Infoframe SDP uses the same Dynamic Range and Mastering (DRM) information (CTA-861-G spec.) such as HDMI DRM infoframe. But DP SDP header and payload structure are different from HDMI DRM Infoframe. Therefore unpacking DRM infoframe for DP requires skipping of a verifying checksum. v9: Add clear comments to hdmi_drm_infoframe_unpack_only() and hdmi_drm_infoframe_unpack() (Laurent Pinchart) Signed-off-by: Gwan-gyeong Mun Reviewed-by: Uma Shankar Cc: Laurent Pinchart Cc: Ville Syrjala Acked-by: Daniel Vetter Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20200514060732.3378396-2-gwan-gyeong.mun@intel.com

ADD HLG EOTF to the list of EOTF transfer functions supported. Hybrid Log-Gamma (HLG) is a high dynamic range (HDR) standard. HLG defines a nonlinear transfer function in which the lower half of the signal values use a gamma curve and the upper half of the signal values use a logarithmic curve. v2: Rebase v3: Fixed a warning message v4: Addressed Shashank's review comments v5: Addressed Jonas Karlman's review comment and dropped the i915 tag from header.

drm: Enable HDR infoframe support

2019-05-22T19:46:35Z

Enable Dynamic Range and Mastering Infoframe for HDR content, which is defined in CEA 861.3 spec. The metadata will be computed based on blending policy in userspace compositors and passed as a connector property blob to driver. The same will be sent as infoframe to panel which support HDR. Added the const version of infoframe for DRM metadata for HDR. v2: Rebase and added Ville's POC changes. v3: No Change v4: Addressed Shashank's review comments and merged the patch making drm infoframe function arguments as constant. v5: Rebase v6: Fixed checkpatch warnings with --strict option.

drm: Add HDR source metadata property

2019-05-22T19:46:35Z

This patch adds a blob property to get HDR metadata information from userspace. This will be send as part of AVI Infoframe to panel. It also implements get() and set() functions for HDR output metadata property.The blob data is received from userspace and saved in connector state, the same is returned as blob in get property call to userspace. v2: Rebase and modified the metadata structure elements as per Ville's POC changes. v3: No Change v4: Addressed Shashank's review comments v5: Rebase. v6: Addressed Brian Starkey's review comments, defined new structure with header for dynamic metadata scalability. Merge get/set property functions for metadata in this patch. v7: Addressed Jonas Karlman review comments and defined separate structure for infoframe to better align with CTA 861.G spec. Added Shashank's RB. v8: Addressed Ville's review comments. Moved sink metadata structure out of uapi headers as suggested by Jonas Karlman. v9: Rebase and addressed Jonas Karlman review comments. v10: Addressed Ville's review comments, dropped the metdata_changed state variable as its not needed anymore.
