Subject: [PATCH] msm: cpu: overclock: use higher bus speed at lower CPU freqs
Thanks to @bedalus and @mrg666
Bedalus suggested that if lower CPU frequencies can offer higher bus
speed,
GPU use during games wouldn't require higher CPU frequency.
My testing demonstrated 4C drop in CPU temp during 3DMark benchmark.
Still needs to be tested for everyday use.
