Fields

event_code: c_uint

< preset (0x8xxxxxxx) or native (0x4xxxxxxx) event code

symbol: [c_char; 1024]

< name of the event

short_descr: [c_char; 64]

< a short description suitable for use as a label

long_descr: [c_char; 1024]

< a longer description: typically a sentence for presets, possibly a paragraph from vendor docs for native events

component_index: c_int

< component this event belongs to

units: [c_char; 64]

< units event is measured in

location: c_int

< location event applies to

data_type: c_int

< data type returned by PAPI

value_type: c_int

< sum or absolute

timescope: c_int

< from start, etc.

update_type: c_int

< how event is updated

update_freq: c_int

< how frequently event is updated

count: c_uint

< number of terms (usually 1) in the code and name fields

• presets: these are native events
• native: these are unused

event_type: c_uint

< event type or category for preset events only

derived: [c_char; 64]

< name of the derived type

• presets: usually NOT_DERIVED
• native: empty string

postfix: [c_char; 256]

< string containing postfix operations; only defined for preset events of derived type DERIVED_POSTFIX

code: [c_uint; 12]

< array of values that further describe the event:

• presets: native event_code values
• native:, register values(?)

name: [[c_char; 256]; 12]

< names of code terms:

note: [c_char; 1024]

< an optional developer note supplied with a preset event to delineate platform specific anomalies or restrictions
