Bug description:
[Impact]
Image is distorted with PRIME, caused by mismatch in stride alignment between
intel and amdgpu/nvidia after intel bumped the alignment to 256 bytes.
[Fix]
Upstream fixed it in 21.2-series, and backport to 21.0.x needs four commits
in total.
[Test case]
1. Connect a monitor on the AMD GPU.
2. Power on the system and boot into OS.
3. Run below command to launch glxgears
Cmd> DRI_PRIME=1 glxgears -info
* Expected result
The image is not distorted while running the glxgears
* Actual result
The image is distorted while running the glxgears
[Where things might go wrong]
This is a regression caused by the intel driver, so the backports merely fix
what got broken. Regressions would only manifest on hybrid graphics platforms.
