This has been validated on TGL using IGT. Note:Only a single instance of WD transcoder is being considered for now, using multiple WD transcoder may not work. The support for the same will be added in next set of patches. suraj kandpal (4): drm: add writeback pointers to drm_connector drm/komeda: change driver to use drm_writeback_connector.base pointer drm/i915: Define WD trancoder for i915 drm/i915: Enabling WD Transcoder .../gpu/drm/arm/display/komeda/komeda_crtc.c | 2 +- .../gpu/drm/arm/display/komeda/komeda_kms.h | 3 +- .../arm/display/komeda/komeda_wb_connector.c | 9 +- drivers/gpu/drm/drm_writeback.c | 19 +- drivers/gpu/drm/i915/Makefile | 2 + drivers/gpu/drm/i915/display/intel_acpi.c | 1 + drivers/gpu/drm/i915/display/intel_display.c | 166 ++- drivers/gpu/drm/i915/display/intel_display.h | 11 + .../drm/i915/display/intel_display_power.h | 1 + .../drm/i915/display/intel_display_types.h | 9 + drivers/gpu/drm/i915/display/intel_dpll.c | 6 + drivers/gpu/drm/i915/display/intel_opregion.c | 3 + .../gpu/drm/i915/display/intel_wb_connector.h | 20 + drivers/gpu/drm/i915/display/intel_wd.c | 1139 +++++++++++++++++ drivers/gpu/drm/i915/display/intel_wd.h | 70 + .../drm/i915/display/skl_universal_plane.c | 1 - drivers/gpu/drm/i915/i915_drv.h | 5 + drivers/gpu/drm/i915/i915_irq.c | 8 +- drivers/gpu/drm/i915/i915_pci.c | 7 +- drivers/gpu/drm/i915/i915_reg.h | 141 +- include/drm/drm_connector.h | 3 + include/drm/drm_writeback.h | 6 +- 22 files changed, 1560 insertions(+), 72 deletions(-) create mode 100644 drivers/gpu/drm/i915/display/intel_wb_connector.h create mode 100644 drivers/gpu/drm/i915/display/intel_wd.c create mode 100644 drivers/gpu/drm/i915/display/intel_wd.h
