Subject[PATCH 0/2] cpufreq: ondemand: Eliminate the deadband effect
Date
Hi all,

This patchset changes slightly the calculation of target frequency to
eliminate the deadband effect (explained in patch 2 changelog) that it
seems to slow down the CPU in low and medium loads.

Patch 1 introduces a new relation (RELATION_C) for the next frequency
selection, which chooses the closest frequency to target.

Patch 2 is the actual change to ondemand governor.

You may find graphs with the 'deadband' effect and benchmark results:

Thanks
