Hah, okay... Don't take it for too much. Anyway your word weighs much more than my one... > hope this eventually works with > ITS ;-) You know... There are actually problems with irqfd. However i'm not sure whether they are result of some bug or of poorly made vGIC CPU interface software emulation. I don't have hardware with working vGICv3 here. With GICv2m everything is fine, but code path is quite different, and LPI != SPI. This is further overcomplicated by the fact that as soon as i start up the profiler, the problem goes away. Looks like increased number of context switches have impact. Actually, the problem is very poor vhost-net throughput, which jumps up when i start the profiler and goes back down when i stop it. Just to note... I'm off since now for a small vacation, will be back on monday or tuesday. See you guys!
