[PATCH i-g-t 2/5] lib/vmwgfx: Allow using any buffer handle as a surface backing
Zack Rusin

Thu Jun 27 19:56:12 UTC 2024
Allow using any buffer handle as a surface backing to allow testing
prime/dma-buf imports. This will allow addition of vmwgfx specific
drm prime tests.
The code always expected a mob structure created via the explicit
alloc dmabuf ioctl which made using buffers created via dumb_buffer
drm interface impossible.
