    Subject[PATCH 0/2] Add allowed CPU capacity knowledge to EAS
    Date
    Hi all,

    This is a patch set which aims to add knowledge about reduced CPU capacity
    into the Energy Model (EM) and Energy Aware Scheduler (EAS). Currently the
    issue is that SchedUtil CPU frequency and EM frequency are not aligned,
    when there is a CPU thermal capping. This causes an estimation error.
    This patch set provides the information about allowed CPU capacity
    into the EM (thanks to thermal pressure signal). This improves the
    energy estimation. More info about this mechanism can be found in the
    patches comments.

    Regards,
    Lukasz
