Subject: [PATCH] vc4_place: Don't reject fractional source coords Subject: [PATCH] vc4/drm: vc4_plane: Remove subpixel positioning check
There is little harm in ignoring fractional coordinates
(they just get truncated).
Without this:
modetest -M vc4 -F tiles,gradient -s 32:1920x1080-60 -P89@74:1920x1080*.1.1@XR24
is rejected. We have the same issue in Kodi when trying to
use zoom options on video.
Note: even if all coordinates are fully integer. e.g.
src:[0,0,1920,1080] dest:[-10,-10,1940,1100]
it will still get rejected as drm_atomic_helper_check_plane_state
uses drm_rect_clip_scaled which transforms this to fractional src coords
