Sure, but I'm not sure whether this is the correct way to do this - if some other libva client does an execbuf in-between couldn't these register get overwritten? It sounds like the kernel should capture these registers for userspace in a race-free way and then provide them with maybe an extension to the reset-stats ioctl? I definitely want to see how this is used in libva before signing up for a new kernel interface. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation +41 (0) 79 365 57 48 - http://blog.ffwll.ch _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
