Class Documentation

anonymous_namespace{powerd++.cpp}::Global::ACSet

struct anonymous_namespace{powerd++.cpp}::Global::ACSet

Per AC line state settings.

Collaboration diagram for anonymous_namespace{powerd++.cpp}::Global::ACSet:

Class Members
mhz_t	freq_max	Highest frequency to set in MHz.
mhz_t	freq_min	Lowest frequency to set in MHz.
const char *const	name	The string representation of this state.
mhz_t	target_freq	Fixed clock frequencies to use if the target load is set to 0.
cptime_t	target_load	Target load times [0, 1024]. The value 0 indicates the corresponding fixed frequency setting from target_freqs should be used.

Member Data Documentation

acstates

ACSet anonymous_namespace{powerd++.cpp}::Global::acstates[3]

Initial value:

{
        {FREQ_UNSET,       FREQ_UNSET,       ADP,  0, "battery"},
        {FREQ_UNSET,       FREQ_UNSET,       HADP, 0, "online"},
        {FREQ_DEFAULT_MIN, FREQ_DEFAULT_MAX, HADP, 0, "unknown"}
    }

The power states.

groups

std::unique_ptr<CoreGroup[]> anonymous_namespace{powerd++.cpp}::Global::groups {nullptr}

This buffer is to be allocated with the number of core groups.

A core group is created by init() for each core that has a dev.cpu.d.freq handle.

pidfilename

const char* anonymous_namespace{powerd++.cpp}::Global::pidfilename {POWERD_PIDFILE}

Name of an alternative pidfile.

If not given pidfile_open() uses a default name.

tempctl_name

const char* anonymous_namespace{powerd++.cpp}::Global::tempctl_name {TEMPERATURE}

The sysctl name pattern for the temperature sysctl.

May contain a single d.
