Hmm, that is unfortunate, I'd assumed that silence meant latest version was working in CI.. dma_sync_sg_* doesn't work on x86? It would be kinda unfortunate to have vgem only work on x86 *or* arm.. maybe bringing back drm_cflush_pages() could make it work in both cases BR, -R _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
