Supports attach

Attach must first ptrace and stop the thread/process

Available domains

Available granularities

Index into the vector array for this component; set at init time

counters have unit masks

Type of component

Supports specifying cpu number to use with event set

The default domain when this component is used

The default granularity when this component is used

Description of the component

0 if enabled, otherwise error code from initialization

Reason for failure of initialization

Supports a user level PMC read instruction

Supports a fast real timer

Supports a fast virtual timer

hw overflow intr, does not need to be emulated in software

Signal used by hardware to deliver PMC events

Supports child processes inheriting parents counters

Component is ready to use

In kernel multiplexing

Name of the component we're using

Number of hardware counters the component supports

Number of hardware counters the component or PAPI can multiplex supports

Number of native events the component supports

Number of preset events the component supports

list of pmu names supported by this component

Using POSIX 1b interval timers (timer_create) instead of setitimer

Performance interrupts happen precisely

Short name of component, to be prepended to event names
