Not sure yet, are there any changes (too hard to check for me). there will be no visible changes. using the HPET as a clocksource (in JACK) is intended to guard against oddities caused by CPU frequency scaling. if JACK uses the CPU instruction counter to check the passage of wallclock time, its sense of time passing can be skewed by the CPU being sped up and slowed down. there are no performance improvements or behavioral changes expected from using the HPET instead. i have no idea if using the HPET as the system (kernel) clocksource offers the same protection. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
