Author: Nicolai Hähnle <[email protected]> Date: Tue Jun 6 19:21:26 2017 +0200 gallium/radeon/gfx9: fix PBO texture uploads to compressed textures st/mesa creates a surface that reinterprets the compressed blocks as RGBA16UI or RGBA32UI. We have to adjust width0 & height0 accordingly to avoid out-of-bounds memory accesses by CB.
