That is still the case, user space decides which dma-bufs it'll go keep cached. But kernel space can see what user space is doing, so there is no need to explicitly tell the kernel whenever a cached dma-buf exists or not. cheers, Gerd _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
