tests/kms_prime: Use 256B aligned width
kms_prime uses vgem driver for fb creation which does not
take care of intel's 64B align requirement. As we want to
keep vgem driver clean we are doing align requirement in
kms_prime test itself.
Also having different alignment requirement by different drivers,
256B aligned should work for all drm drivers.
amdgpu and radeon, amdgpu_align_pitch: 256B
armada, armada_pitch: 128B
exynos_drm_gem_dumb_create: No alignment required
drm_gem_shmem_dumb_create: 8B
drm_gem_vram_fill_create_dumb: 8B
Thus 256B covers everything we see in the kernel drm drivers.
Changes since V2:
- Edited commit message to give more detailed info about patch requirement - zkempczy/Daniel
Changes since V1:
- Edited commit message with driver compatible with 256B align - Daniel
