Firmware may change CPU capabilities as a result of thermal events in the system or to account for changes in the TDP (thermal design power) level. This notification type will allow user space to avoid running workloads on certain CPUs or proactively adjust power limits to avoid future events. The netlink message consists of a nested attribute (THERMAL_GENL_ATTR_CPU_CAPABILITY) with three attributes: * THERMAL_GENL_ATTR_CPU_CAPABILITY_ID (type u32): -- logical CPU number * THERMAL_GENL_ATTR_CPU_CAPABILITY_PERFORMANCE (type u32): -- Scaled performance from 0-1023 * THERMAL_GENL_ATTR_CPU_CAPABILITY_EFFICIENCY (type u32): -- Scaled efficiency from 0-1023 Cc: Andi Kleen <ak@xxxxxxxxxxxxxxx> Cc: Aubrey Li <aubrey.li@xxxxxxxxxxxxxxx> Cc: Lukasz Luba <lukasz.luba@xxxxxxx> Cc: Tim Chen <tim.c.chen@xxxxxxxxxxxxxxx> Cc: "Ravi V.

My apologies Rafael, I missed that email. I've looked at the patches 6/7 and 7/7 and they look OK with the scaling.
