I have started testing this patchset on S905X. I'm not very far into it yet, but noticed this spam in the kernel logs: [ 192.230935] meson-vdec c8820000.video-codec: VIFIFO usage (16777858) > VIFIFO size (16777216) So far it seems to be printed once per frame while decoding bbb_sunflower_1080p_30fps_normal.mp4 from blender fondation. I'm don't think I have ever seen that one before. > > The issue in the V1 patchset at [1] is solved by patch #1 following comments > and requirements from hans.
