Public bug reported:
Calling vaCreateSurfaces with:
data_size = 8388608 (0x800000) from drm_gem_open
stride = 7680
width = 1920
height = 1080
fails:
i965_drv_video.c:1507: i965_suface_external_memory: Assertion
`(((obj_surface->height) & ((16)-1)) == 0)' failed.
To workaround this failure I need to reduce the data_size to satisfy the
above assertion and its sibling that requires 32-row alignment:
data_size -= data_size % (stride * 32);
