Changes in V5 ============= * More info in commit messages on the rationale of changes being added to the kernel. * Minor fixes Changes in V4 ============= 1) Add module parameter for freesync video mode * Change module parameter name to freesync_video 2) Add freesync video modes based on preferred modes: * Cosmetic fixes * Added comments about all modes being added by the driver. 3) Skip modeset for front porch change * Added more conditions for checking freesync video mode Changes in V3 ============= 1) Add freesync video modes based on preferred modes: * Cache base freesync video mode during the first iteration to avoid iterating over modelist again later. * Add mode for 60 fps videos 2) Skip modeset for front porch change * Fixes for bug exposed by caching of modes. Changes in V2 ============= 1) Add freesync video modes based on preferred modes: * Remove check for connector type before adding freesync compatible modes as VRR support is being checked, and there is no reason to block freesync video support on eDP. * use drm_mode_equal() instead of creating same functionality. * Additional null pointer deference check * Removed unnecessary variables. * Cosmetic fixes. 2) Skip modeset for front porch change * Remove _FSV string being appended to freesync video modes so as to not define new policies or break existing application that might use the mode name to figure out mode resolution. * Remove unnecessary variables * Cosmetic fixes. -- This patchset enables freesync video mode usecase where the userspace can request a freesync compatible video mode such that switching to this mode does not trigger blanking. This feature is guarded by a module parameter which is disabled by default. Enabling this paramters adds additional modes to the driver modelist, and also enables the optimization to skip modeset when using one of these modes. -- Aurabindo Pillai (3): drm/amd/display: Add module parameter for freesync video mode drm/amd/display: Add freesync video modes based on preferred modes drm/amd/display: Skip modeset for front porch change drivers/gpu/drm/amd/amdgpu/amdgpu.h | 1 + drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 12 + .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 401 ++++++++++++++++-- .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h | 3 + 4 files changed, 382 insertions(+), 35 deletions(-) -- 2.30.0 _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
