[Mesa-dev] [PATCH] nir/lower_tex: Fix the channel ordering during conversion of AYUV images

[Vivek Kasireddy]

From: "Kasireddy, Vivek" <vivek.kasireddy at intel.com>

The channel ordering should be 1230 instead of 2103.

While displaying the packed YUV buffers generated by the Vivid (Virtual
Video) driver on Weston, it was observed that AYUV images were not
displayed correctly. Changing the ordering to 1230 makes AYUV buffers
display as expected.
