Simon Ser c6dd5e3c2e backend/drm: check buffer format for multi-GPU ... Fixes on-screen corruption when displaying a fullscreen client with an implicit modifier on the secondary GPU. What happens here: - Client allocates a buffer with an INVALID modifier on primary GPU. - Compositor attempts to scan-out this buffer on an output connected to secondary GPU. - Buffer is imported to secondary GPU, and is interpreted as if it had the secondary GPU's implicit tiling, even though it has the primary GPU's implicit tiling. We need to forbid cross-device imports with implicit modifiers. The mgpu_formats list is stripped from any INVALID modifier so checking that fixes the bug. Using the mgpu_formats list has an additional benefit: the buffer is rejected in the test commit if it doesn't have a format supported by the multi-GPU renderer. Requires this Mesa bugfix: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/31725		2024-11-28 20:27:48 +01:00
