* MFC r273737, 273739bapt2014-11-031-1/+7
| | | | | | | | Clarify the documentation of pmcstat: the -d argument should be passed before -p, -s, -P or -S to be taken in account Differential Revision: https://reviews.freebsd.org/D1011 Reviewed by: adrian, gnn

* MFC: 266209gnn2014-05-303-3/+51
| | | | | | | | Add a command line argument (-l) to end event collection after some number of seconds. The number of seconds may be a fraction. Submitted by: Julien Charbon <jcharbon@versign.com> Relnotes: yes
* MFC r266208: Speed up pmcstat by improving string hashemaste2014-05-231-3/+3
| | | | | | | | | In one case generating callgraph output from a 24MB system-wide sampling data file took 17.4 seconds on average. Profiling showed pmcstat spending a lot of time in strcmp, due to hash collisions. Replacing the XOR-only hash with FNV-1a reduces the run time for my test by 40%.
* Merged r262424-262425,265085scottl2014-05-077-4/+205
| | | | | | | Add the -a option to pmcstat. This produces a full stack track on the sampled points. See the man page for details on how this works. Obtained from: Netflix, Inc.
* More -Wmissing-variable-declarations fixes.ed2012-10-194-16/+15
| | | | | | | | | | | | | | | | In addition to adding `static' where possible: - bin/date: Move `retval' into extern.h to make it visible to date.c. - bin/ed: Move globally used variables into ed.h. - sbin/camcontrol: Move `verbose' into camcontrol.h and fix shadow warnings. - usr.bin/calendar: Remove unneeded variables. - usr.bin/chat: Make `line' local instead of global. - usr.bin/elfdump: Comment out unneeded function. - usr.bin/rlogin: Use _Noreturn instead of __dead2. - usr.bin/tset: Pull `Ospeed' into extern.h. - usr.sbin/mfiutil: Put global variables in mfiutil.h. - usr.sbin/pkg: Remove unused `os_corres'. - usr.sbin/quotaon, usr.sbin/repquota: Remove unused `qfname'.

* Add software PMC support.fabient2012-03-281-0/+15
| | | | | | | | | | | | | New kernel events can be added at various location for sampling or counting. This will for example allow easy system profiling whatever the processor is with known tools like pmcstat(8). Simultaneous usage of software PMC and hardware PMC is possible, for example looking at the lock acquire failure, page fault while sampling on instructions. Sponsored by: NETASQ MFC after: 1 month
* - Support inlined location in calltree output.fabient2012-03-282-241/+402
| | | | | | | | | | | | In case of multiple level of inlining all the locations are flattened. Require recent binutils/addr2line (head works or binutils from ports with the right $PATH order). - Multiple fixes in the calltree output (recursion case, ...) - Fix the calltree top view that previously hide some shared nodes.

* Add a flush of the current PMC log buffer before displaying the next top.fabient2011-10-182-9/+11
| | | | | | | | As the underlying block is 4KB if the PMC throughput is low the measurement will be reported on the next tick. pmcstat(8) use the modified flush API to reclaim current buffer before displaying next top. MFC after: 1 month
* Convert pmcstat about using cpuset_t rather than relying on plain 32 bitattilio2011-08-073-74/+81
| | | | | | | | | | | | | | | | ints. That fixes a first bug where pmcstat wasn't using the old cpumask_t interface and now also brings the full support for more than 32 cpus. While here, make the functions pmcstat_clone_event_descriptor() and pmcstat_get_cpumask() private to pmcstat. The problem of assuming cpu dense masks still persists and should be eventually fixed, as reported by avg. Tested by: pluknet Reviewed by: gnn Approved by: re (kib)
