With SEV memory encryption and in some cases also with SME memory encryption, coherent memory is unencrypted. In those cases, TTM doesn't set up the correct page protection. Fix this by having the TTM coherent page allocator call into the platform code to determine whether coherent memory is encrypted or not, and modify the page protection if it is not. v2: - Use force_dma_unencrypted() rather than sev_active() to catch also the special SME encryption cases. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
