Sets Performance Monitor programmation for a target pthread.
Performance Monitor APIs Library (libpmapi.a)
The pm_set_program_pthread subroutine sets the Performance Monitor programmation for a target pthread. The pthread must be stopped and must be part of a debuggee process, under the control of the calling process. The setting includes the events to be counted and a mode in which to count. The events to count are in a list of event identifiers. The identifiers must be selected from the lists returned by the pm_inititialize subroutine.
If the pthread is running in 1:1 mode, only the tid parameter must be specified. If the pthread is running in m:n mode, only the ptid parameter must be specified. If both the ptid and tid parameters are specified, they must be referring to a single pthread with the ptid parameter specified and currently running on a kernel thread with specified tid parameter.
The counting mode includes User Mode and/or Kernel Mode, and the Initial Counting State. The defaults are set to Off for User Mode and Kernel Mode, and the Initial Default State is set to delay counting until the pm_start_pthread subroutine is called.
If the list includes an event which can be used with a threshold (as indicated by the pm_initialize subroutine), a threshold value can also be specified.
| Item | Description |
|---|---|
| pid | Process ID of target pthread. Target process must be a debuggee of the caller process. |
| tid | Thread ID of target pthread. To ignore this parameter, set it to 0. |
| ptid | Pthread ID of the target pthread. To ignore this parameter, set it to 0. |
| *prog | Specifies the event modes to use
in Performance Monitor setup.
The following modes are supported:
