Ok. I assumed the alternative to merge the 3 patches via drm-misc-next, wait for that to get merged back to i915 and then merge the rest to i915 was still a preferred way; wondering now if in general this is better to avoid merge conflicts similar to the one reported now wrt. "drm/dp_mst: Fix fractional DSC bpp handling". In any case yes, I can CC dri-devel the whole patchset whenever there are any drm changes in it. While still wondering about the ideal approach above, I'd still prefer if the 3 drm patches in this one could also get merged via the i915 tree. --Imre > BR, > Jani. > > > > drm/i915/dp: Replace intel_dp_is_uhbr_rate() with > > drm_dp_is_uhbr_rate() > > drm/i915/dp: Account for channel coding efficiency on UHBR links > > drm/i915/dp: Fix UHBR link M/N values > > drm/i915/dp_mst: Calculate the BW overhead in > > intel_dp_mst_find_vcpi_slots_for_bpp() > > drm/i915/dp_mst: Fix PBN / MTP_TU size calculation for UHBR rates > > drm/i915/dp: Report a rounded-down value as the maximum data rate > > drm/i915/dp: Simplify intel_dp_max_data_rate() > > drm/i915/dp: Reuse intel_dp_{max,effective}_data_rate in > > intel_link_compute_m_n() > > > > .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 5 +- > > .../amd/display/amdgpu_dm/amdgpu_dm_helpers.c | 3 +- > > .../display/amdgpu_dm/amdgpu_dm_mst_types.c | 5 +- > > drivers/gpu/drm/display/drm_dp_mst_topology.c | 31 +++- > > drivers/gpu/drm/i915/display/intel_display.c | 51 ++---- > > drivers/gpu/drm/i915/display/intel_dp.c | 78 +++++++--- > > drivers/gpu/drm/i915/display/intel_dp.h | 5 +- > > drivers/gpu/drm/i915/display/intel_dp_mst.c | 55 +++++-- > > drivers/gpu/drm/nouveau/dispnv50/disp.c | 6 +- > > .../gpu/drm/tests/drm_dp_mst_helper_test.c | 145 ++++++++++++++++++ > > include/drm/display/drm_dp_helper.h | 13 ++ > > include/drm/display/drm_dp_mst_helper.h | 7 +- > > 12 files changed, 311 insertions(+), 93 deletions(-) > > -- > Jani Nikula, Intel
