Description
The geopm_agent_c interface is used for bitwise converting
signal values returned from the PlatformIO, from their 64-bit fields
into the double representation, and vice versa.
geopm_signal_to_field()Convert a signal that is implicitly a 64-bit field especially useful for converting raw 64 bit MSR fields. Takes in a signal value returned by
PlatformIO::sample()orPlatformIO::read_signal()for a signal with a name that ends with the'#'character.geopm_signal_to_field()Convert a 64-bit field into a double representation appropriate for a signal returned by an
IOGroup. Takes in an arbitrary 64-bit field to be stored in a double precision value.
