We can simulate multi-client (both same and mixed workloads) using gem_wsim to work out optimal strategies and then compare our simulation with the actual transcoder. This fixed round-robin turns out to be one of the worst. No user is advised to use this method. At the present time, intel-media is explicit, but libva still seems to use it, with the exception of batches that must execute on vcs0. Oh well. > > Signed-off-by: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> > > Cc: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> > > Cc: Joonas Lahtinen <joonas.lahtinen@xxxxxxxxxxxxxxx> > > Reviewed-by: Joonas Lahtinen <joonas.lahtinen@xxxxxxxxxxxxxxx> > > Regards, Joonas > _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
