ryo 473c5ef3b0 fixed parsing of event options.

ryo 07a5918990 Improve tprof(8) 
- Added "tprof count" subcommand to perform counts only.
- Event options (u,k) are now optional. The default value is both userland and kernel. (:uk)
- Event counters can be displayed with SIGINFO during `tprof monitor' or `tprof count'.

ryo caba1a6f47 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.

maxv 5ae6235d0e Remove tpfmt(1). Its code was merged into tprof(8). 2018-07-13 11:14:14 +00:00
maxv 96b21aedb9 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.
 2018-07-13 11:03:36 +00:00
maxv 48aa814610 Skylake/Kabylake are family 6, so add a check for that. While here improve 
the layout of "tprof list".

maxv ab933b7bbb Change the arguments of the tprof tool, to match the behavior of pmc(1) and 
cpuctl(8). They become:

	tprof list
	tprof monitor -e name:option [-o outfile] command
 2018-07-13 09:04:31 +00:00
maxv 8dd2f31aad Inline the values in amd_f10h_names[], we're not going to use defines for 
each CPU model found in the wild.
