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
