This patchset adds the missing upstream commits to at least fix the panic/black screen on boot. They are applicable to 6.12, 6.6, and 6.1 as those are the currently supported kernels that 7009e3af0474aca5f64262b3c72fb6e23b232f9b got backported to. 6.1 needs two extra backports for these two commits to be cherry-picked cleanly. Those are 96ce96f8773da4814622fd97e5226915a2c30706 d09ef243035b75a6d403ebfeb7e87fa20d7e25c6 Timur Kristóf (2): drm/amd/display: Add pixel_clock to amd_pp_display_configuration drm/amd/pm: Use pm_display_cfg in legacy DPM (v2) .../amd/display/amdgpu_dm/amdgpu_dm_pp_smu.c | 1 + .../dc/clk_mgr/dce110/dce110_clk_mgr.c | 2 +- .../drm/amd/display/dc/dm_services_types.h | 2 +- drivers/gpu/drm/amd/include/dm_pp_interface.h | 1 + drivers/gpu/drm/amd/pm/amdgpu_dpm_internal.c | 67 +++++++++++++++++++ .../gpu/drm/amd/pm/inc/amdgpu_dpm_internal.h | 2 + drivers/gpu/drm/amd/pm/legacy-dpm/kv_dpm.c | 4 +- .../gpu/drm/amd/pm/legacy-dpm/legacy_dpm.c | 6 +- drivers/gpu/drm/amd/pm/legacy-dpm/si_dpm.c | 65 ++++++------------ .../gpu/drm/amd/pm/powerplay/amd_powerplay.c | 11 +-- 10 files changed, 101 insertions(+), 60 deletions(-) -- 2.53.0
