Subject: [PATCH 0/3] drm/sun4i: DE2/DE3 improvements
Date: Thu, 28 Feb 2019 21:03:26 +0100 [thread overview]
Message-ID: <20190228200329.11128-1-jernej.skrabec@siol.net> (raw)
DE2 and DE3 VI channels support coarse scaling to overcome VI scaler
limitations. That is especially useful for downscaling big planes, for
example 4K to 1080p.
Following patches were tested on H3 and A64 with 4K video playback on
1080p monitor. Without them, picture was mangled.
Please take a look.
Best regards,
Jernej
