I would prefer it if you extended intel_mark_busy() to note the source of work, and so extended the busy/idle tracking per-ring with the appropriate hooks for vlv to modify RPS, like how we already do for the general gen6_rps_busy and gen6_rps_idle. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
