/dev/cpu_dma_latency or setting '*.max_cstate=0 idle=poll' and power management

[Jeremy Jongepier <jeremy@xxxxxxxxxxxxxx>]

Hello,

How does opening /dev/cpu_dma_latency and disabling CPU sleep states or 
disabling CPU sleep states with kernel parameters relate to CPU 
frequency scaling? Does disabling sleep states also disable frequency 
scaling? Asking this because I'm attempting to rewrite the 
system_configuration wiki page. Thanks in advance!

Best,

Jeremy
