TGL supports DC3CO only on PipeA in LPSP mpde, so DC3CO doesn't depends on TGL PSR "Transcoder B" feature. B.Specs:49196 DC3CO requirements: *Audio codec idle and disabled. *External displays disabled. WD transcoders and DP/HDMI transcoders must be disabled. *Backlight cannot be driven from the display utility pin. It can be driven from the south display. *This feature should be enabled only in Display Video playback on eDP. *DC5 and DC6 not allowed when this feature is enabled. *PSR2 deep sleep disabled (PSR2_CTL Idle Frames = 0000b) *Disable DC3co before mode set, or other Aux, PLL, and DBUF programming, and do not re-enable until after that programming is completed. *DC3co must not be enabled until after PSR2 is enabled. *DC3co must be disabled before PSR2 is disabled. Anshuman Gupta (9): drm/i915/tgl: Add DC3CO required register and bits drm/i915/tgl: Add DC3CO mask to allowed_dc_mask and gen9_dc_mask drm/i915/tgl: Add power well to enable DC3CO state drm/i915/tgl: mutual exclusive handling for DC3CO and DC5/6 drm/i915/tgl: Add helper function to prefer dc3co over dc5 drm/i915/tgl: Add VIDEO power domain drm/i915/tgl: DC3CO PSR2 helper drm/i915/tgl: switch between dc3co and dc5 based on display idleness drm/i915/tgl: Add DC3CO counter in i915_dmc_info drivers/gpu/drm/i915/display/intel_display.c | 9 + .../drm/i915/display/intel_display_power.c | 290 +++++++++++++++++- .../drm/i915/display/intel_display_power.h | 11 + drivers/gpu/drm/i915/display/intel_psr.c | 44 +++ drivers/gpu/drm/i915/display/intel_psr.h | 2 + drivers/gpu/drm/i915/i915_debugfs.c | 6 + drivers/gpu/drm/i915/i915_drv.h | 8 + drivers/gpu/drm/i915/i915_params.c | 3 +- drivers/gpu/drm/i915/i915_reg.h | 10 + drivers/gpu/drm/i915/intel_pm.c | 2 +- drivers/gpu/drm/i915/intel_pm.h | 2 + 11 files changed, 376 insertions(+), 11 deletions(-)
