[PATCH i-g-t 1/2] tests/kms_pwrite_crc: handle missing get_caching

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



gem_get_caching is not supported on discrete. The object itself should
already be coherent with the display engine as-is on such platforms, by
virtue of the scanout happening via local-memory.
