Hi,
Maybe Tomi can help with this, of forward this code for someone for review.
This test tries to scale 320x240 image and display it rotated on
1080x1920 LCD in portrait orientation. Quick look into omapdrm code
shows that that it supports DMM/TILER, so it would seem it should work.
Direct scaling seems to work right, see orig.jpg for original image and
scaled.jpg rescaled to 1080x1920 (in hardware). However rotation only
partially works, the lines get rotated but are squished, the middle of
image is blank and there are some artifacts (see rotated.jpg).
I'll keep trying things, but maybe somebody can give some hints on
what's going on.
