X-Git-Tag: firefly_0821_release~4090^2~761
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=c9d6c1ff8d0e6064b3c42c9f5a6baf687a30d29b;p=firefly-linux-kernel-4.4.55.git

cpufreq: interactive: apply intermediate load to max speed not current

Evaluate spikes in load (below go_hispeed_load) against the maximum
speed supported by the device, not the current speed (which tends to
make it too difficult to raise speed to intermediate levels until
very busy).
