Koen Vandeputte 1fa6b2639c ipq40xx: switch to performance governor by default ... Doing a simple ping to my device shows this: 64 bytes from 10.0.253.101: icmp_seq=1 ttl=64 time=2.00 ms 64 bytes from 10.0.253.101: icmp_seq=2 ttl=64 time=2.02 ms 64 bytes from 10.0.253.101: icmp_seq=3 ttl=64 time=1.68 ms 64 bytes from 10.0.253.101: icmp_seq=4 ttl=64 time=1.91 ms 64 bytes from 10.0.253.101: icmp_seq=5 ttl=64 time=1.92 ms 64 bytes from 10.0.253.101: icmp_seq=6 ttl=64 time=2.04 ms Some users even report higher values on older kernels: 64 bytes from 192.168.1.10: seq=0 ttl=64 time=0.612 ms 64 bytes from 192.168.1.10: seq=1 ttl=64 time=2.852 ms 64 bytes from 192.168.1.10: seq=2 ttl=64 time=2.719 ms 64 bytes from 192.168.1.10: seq=3 ttl=64 time=2.741 ms 64 bytes from 192.168.1.10: seq=4 ttl=64 time=2.808 ms The problem is that the governor is set to Ondemand, which causes the CPU to clock all the way down to 48MHz in some cases. Switching to performance governor: 64 bytes from 10.0.253.101: icmp_seq=1 ttl=64 time=0.528 ms 64 bytes from 10.0.253.101: icmp_seq=2 ttl=64 time=0.561 ms 64 bytes from 10.0.253.101: icmp_seq=3 ttl=64 time=0.633 ms 64 bytes from 10.0.253.101: icmp_seq=4 ttl=64 time=0.526 ms In theory, using the Performance governor should increase power draw, but it looks like it really does not matter for this soc. Using a calibrated precision DC power supply (cpu idle): Ondemand 24.00V * 0.134A = 3.216 Watts 48.00V * 0.096A = 4.608 Watts Performance 24.00V * 0.135A = 3.240 Watts 48.00V * 0.096A = 4.608 Watts Let's simply switch to the Performance governor by default to fix the general jittery behaviour on devices using this soc.
