Hello, whenever I start the xserver for the first time the benchmarking section in my Xorg.0.log file says (see also attached files): ... (II) VIA(0): [drm] Irq handler installed, using IRQ 16. (II) VIA(0): direct rendering enabled (II) VIA(0): Benchmarking video copy. Less is better. (--) VIA(0): Timed libc YUV420 copy... 13608514. Throughput: 79.6 MiB/s.
