At this point, we're just removing a few cts/sts (spin_lock_irqsave/restore) from the execlists paths. It just makes me feel happier to have fewer _irq dotted around prior to RT. The trade-off is that they will hound us for using irq_work instead! :) -Chris _______________________________________________ Intel-gfx mailing list Intelfirstname.lastname@example.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
