Historically we haven't allowed direct scan-out for legacy KMS, because legacy misses the functionality to make sure a buffer can be scanned out. However with renderer v6 the backend can't figure out anymore whether the buffer comes from its internal swap-chain, because the backend doesn't have an internal swap-chain. The legacy KMS API guarantees that the driver won't reject a buffer as long as it's been allocated with the same parameters as the previous one. Let's check this in legacy_crtc_test. |
