|
|||
This command displays the symbolic event types which can be selected in the
|
||||
various perf commands with the -e option.
|
||||
|
||||
EVENT MODIFIERS
|
||||
---------------
|
||||
|
||||
Events can optionally have a modifer by appending a colon and one or
|
||||
more modifiers. Modifiers allow the user to restrict when events are
|
||||
counted with 'u' for user-space, 'k' for kernel, 'h' for hypervisor.
|
||||
|
||||
The 'p' modifier can be used for specifying how precise the instruction
|
||||
address should be. The 'p' modifier is currently only implemented for
|
||||
Intel PEBS and can be specified multiple times:
|
||||
0 - SAMPLE_IP can have arbitrary skid
|
||||
1 - SAMPLE_IP must have constant skid
|
||||
2 - SAMPLE_IP requested to have 0 skid
|
||||
3 - SAMPLE_IP must have 0 skid
|
||||
|
||||
The PEBS implementation now supports up to 2.
|
||||
|
||||
RAW HARDWARE EVENT DESCRIPTOR
