[RFC v4 5/5] platform/x86/intel/pmc: core: Report duration of time in HW sleep state

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



intel_pmc_core displays a warning when the module parameter
`warn_on_s0ix_failures` is set and a suspend didn't get to a HW sleep
state.

Report this to the standard kernel reporting infrastructure that will
be used to display a percentage of time spent in a hw sleep state.
