[PATCH 2/5] rtla/utils: Add idle state disabling via libcpupower

From: Tomas Glozar Add functions to utils.c to disable idle states through functions of libcpupower. This will serve as the basis for disabling idle states per cpu when running timerlat. Signed-off-by: Tomas Glozar --- tools/tracing/rtla/src/utils.c | 133 +

[PATCH 0/5] rtla: Support idle state disabling via libcpupower in timerlat

From: Tomas Glozar rtla-timerlat allows reducing latency on wake up from idle by setting /dev/cpu_dma_latency during the timerlat measurement. This has an effect on the idle states of all CPUs, including those which are not used by timerlat. Add option --disable-idle-states that disables all
