In order to readout DP SDPs (Secondary Data Packet: DP HDR Metadata Infoframe SDP, DP VSC SDP), it refactors handling DP SDPs codes. It adds new compute routines for DP HDR Metadata Infoframe SDP and DP VSC SDP. And new writing routines of DP SDPs (Secondary Data Packet) that uses computed configs. New reading routines of DP SDPs are added for readout. It adds a logging function for DP VSC SDP. When receiving video it is very useful to be able to log DP VSC SDP. This greatly simplifies debugging. In order to use a common VSC SDP Colorimetry calculating code on PSR, it uses a new psr vsc sdp compute routine. v2: Minor style fix v3: - Add a new drm data structure for DP VSC SDP - Replace a structure name to drm_dp_vsc_sdp from intel_dp_vsc_sdp - Move logging functions to drm core [Jani N] And use drm core's DP VSC SDP logging function - Explicitly disable unused DIPs (AVI, GCP, VS, SPD, DRM. They will be used for HDMI), when intel_dp_set_infoframes() function will be called. v4: - Use struct drm_device logging macros - Rebased v5: - Use intel_de_*() functions for register access - Add warning where a bpc is 6 and a pixel format is RGB. - Addressed review comments from Uma Add kernel docs for added data structures Rename enum dp_colorspace to dp_pixelformat Polish commit message and comments Combine the if checks of sdp.HB2 and sdp.HB3 Add 6bpc to packining and unpacking of VSC SDP v6: Fix enabled infoframe states of lspcon v7: Fix the wrong check of combination bpc 6 and RGB pixelformat v8: - Rebased - Addressed review comments from Laurent Pinchart Rename hdmi_drm_infoframe_unpack_only() to cta_drm_infoframe_unpack_databytes() Add clear comments to cta_drm_infoframe_unpack_databytes() Gwan-gyeong Mun (14): video/hdmi: Add Unpack function for CTA-861-G DRM infoframe DataBytes drm/i915/dp: Read out DP SDPs drm: Add logging function for DP VSC SDP drm/i915: Include HDMI DRM infoframe in the crtc state dump drm/i915: Include DP HDR Metadata Infoframe SDP in the crtc state dump drm/i915: Include DP VSC SDP in the crtc state dump drm/i915: Program DP SDPs with computed configs drm/i915: Add state readout for DP HDR Metadata Infoframe SDP drm/i915: Add state readout for DP VSC SDP drm/i915: Fix enabled infoframe states of lspcon drm/i915: Program DP SDPs on pipe updates drm/i915: Stop sending DP SDPs on ddi disable drm/i915/dp: Add compute routine for DP PSR VSC SDP drm/i915/psr: Use new DP VSC SDP compute routine on PSR drivers/gpu/drm/drm_dp_helper.c | 174 ++++++++ drivers/gpu/drm/i915/display/intel_ddi.c | 19 +- drivers/gpu/drm/i915/display/intel_display.c | 62 +++ drivers/gpu/drm/i915/display/intel_dp.c | 395 ++++++++++--------- drivers/gpu/drm/i915/display/intel_dp.h | 15 +- drivers/gpu/drm/i915/display/intel_lspcon.c | 2 +- drivers/gpu/drm/i915/display/intel_psr.c | 54 +-- drivers/gpu/drm/i915/display/intel_psr.h | 6 +- drivers/gpu/drm/i915/i915_drv.h | 1 + drivers/video/hdmi.c | 74 ++-- include/drm/drm_dp_helper.h | 3 + include/linux/hdmi.h | 2 + 12 files changed, 544 insertions(+), 263 deletions(-)
