Rev6: -Upgrade the debugfs functionality to enable the joining of a specified number of pipes. -Modify the display helpers reliant on the pipe joiner mechanism to use number of pipes joined, instead of joiner flag. -Checkpatch fixes. Rev7: -Use struct intel_display, minor refactoring, and rebase. Rev8: -Address comments from Ville. -Simplified debugfs for forcing joiner, and added option to disable joiner. -Modified the ultra/bigjoiner helpers as suggested by Ville. -Split few of the bigger patches as suggested. Rev9: Rebase Rev10: -Rebase -Fix enable_joined_pipes as suggested by Ville, to avoid propagate is_ultrajoiner. -Enhance the mask to iterate over joiner pipes, as suggested by Ville. Rev11: -Address review comments from Ville -Split changes to dsc helpers to separate patches Ankit Nautiyal (11): drm/i915/display_device: Add Check HAS_DSC for bigjoiner drm/i915/display_debugfs: Allow force joiner only if supported drm/i915/display: Modify debugfs for joiner to force n pipes drm/i915/dp: Add helper to compute num pipes required drm/i915/display: Add debugfs support to avoid joiner drm/i915: Split current joiner hw state readout drm/i915/display: Add macro HAS_ULTRAJOINER() drm/i915/display: Refactor enable_joiner_pipes drm/i915/dp: Modify compressed bpp limitations for ultrajoiner drm/i915/display: Consider ultrajoiner for computing maxdotclock drm/i915/intel_dp: Add support for forcing ultrajoiner Stanislav Lisovskiy (5): drm/i915: Add bigjoiner and uncompressed joiner hw readout sanity checks drm/i915: Implement hw state readout and checks for ultrajoiner drm/i915/display/vdsc: Add ultrajoiner support with DSC drm/i915/dp: Modify helper to get slice count for ultrajoiner drm/i915: Compute config and mode valid changes for ultrajoiner drivers/gpu/drm/i915/display/intel_display.c | 301 +++++++++++++++--- drivers/gpu/drm/i915/display/intel_display.h | 3 + .../drm/i915/display/intel_display_debugfs.c | 71 ++++- .../drm/i915/display/intel_display_device.h | 5 +- .../drm/i915/display/intel_display_types.h | 2 +- drivers/gpu/drm/i915/display/intel_dp.c | 93 ++++-- drivers/gpu/drm/i915/display/intel_dp.h | 6 +- drivers/gpu/drm/i915/display/intel_dp_mst.c | 23 +- drivers/gpu/drm/i915/display/intel_vdsc.c | 11 +- .../gpu/drm/i915/display/intel_vdsc_regs.h | 2 + 10 files changed, 417 insertions(+), 100 deletions(-)
