Member Function Documentation

◆ preDumpStats()

void gem5::PowerState::PowerStateStats::preDumpStats ( )

overridevirtual

Callback before stats are dumped.

This can be overridden by objects that need to perform calculations in addition to the capabiltiies implemented in the stat framework.

For every stats dump, the power state residency and other distribution stats should be computed just before the dump to ensure correct stats value being reported for current dump window. It avoids things like having any unreported time spent in a power state to be forwarded to the next dump window which might have rather unpleasant effects (like perturbing the distribution stats).

Reimplemented from gem5::statistics::Group.

◆ regStats()

void gem5::PowerState::PowerStateStats::regStats ( )

overridevirtual

Callback to set stat parameters.

This callback is typically used for complex stats (e.g., distributions) that need parameters in addition to a name and a description. Stat names and descriptions should typically be set from the constructor usingo from the constructor using the ADD_STAT macro.
