Hi Alexander,
Could you explain with a bit more detail what's the intended usage
scenario for this code?
If you have BootMonitor, it is already capable of booting the kernel.

Evaluation Patch to investigate using load as a representation of the
amount of POTENTIAL cpu compute capacity used rather than a representation
of the CURRENT cpu compute capacity.
If CPUFreq is enabled, scales load in accordance with frequency.

Hi Viresh,
Here are the latest patches for HMP tunables to be included in the MP branch
for the 12.11
release. They depend on Vincent Guittot's patches that you have on -exp-v12
branch which
we need included in the PULL request. Testing shows that they improve power
consumption for HMP.
Thanks

These functions allow to change the load average period used
in the task load average computation through
/sys/kernel/hmp/load_avg_period_ms. This period is the time
in ms to go from 0 to 0.5 load average while running or the
time from 1 to 0.5 while sleeping.
