Improve tprof(4)

- Multiple events can now be handled simultaneously.
- Counters should be configured with TPROF_IOC_CONFIGURE_EVENT in advance,
  instead of being configured at TPROF_IOC_START.
- The configured counters can be started and stopped repeatedly by
  PROF_IOC_START/TPROF_IOC_STOP.
- The value of the performance counter can be obtained at any timing as a 64bit
  value with TPROF_IOC_GETCOUNTS.
- Backend common parts are handled in tprof.c as much as possible, and functions
  on the tprof_backend side have been reimplemented to be more primitive.
- The reset value of counter overflows for profiling can now be adjusted.
  It is calculated by default from the CPU clock (speed of cycle counter) and
  TPROF_HZ, but for some events the value may be too large to be sufficient for
  profiling. The event counter can be specified as a ratio to the default or as
  an absolute value when configuring the event counter.
- Due to overall changes, API and ABI have been changed. TPROF_VERSION and
  TPROF_BACKEND_VERSION were updated.

Ask for a file path with the "analyze" command, instead of reading stdin.

Revision 1.1 / (download) - annotate - [select for diffs], Fri Jul 13 11:03:36 2018 UTC (5 years, 9 months ago) by maxv
Branch: MAIN

Merge tpfmt(1) into tprof(8). We want to have access to everything with
only one tool. The code is copied mostly as-is, and the functionality is
available via the "analyze" command.

Eg:
	tprof monitor -e llc-misses:k -o myfile.out sleep 20
	tprof analyze < myfile.out

Will move soon, I don't like the reading via stdin.
