Maxime Ripard 4f3b254367 drm/vc4: txp: Force alpha to be 0xff if it's disabled ... [ Upstream commit 5453343a88 ] If we use a format that has padding instead of the alpha component (such as XRGB8888), it appears that the Transposer will fill the padding to 0, disregarding what was stored in the input buffer padding. This leads to issues with IGT, since it will set the padding to 0xff, but will then compare the CRC of the two frames which will thus fail. Another nice side effect is that it is now possible to just use the buffer as ARGB.
