* MFC r266903: Update default callchain depth to 16 to match kernelemaste2014-06-061-1/+1
|
* MFC: 266209gnn2014-05-301-0/+2
| | | | | | | | 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
* Merged r262424-262425,265085scottl2014-05-071-0/+1
| | | | | | | 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.
* Convert pmcstat about using cpuset_t rather than relying on plain 32 bitattilio2011-08-071-4/+3
| | | | | | | | | | | | | | | | 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)
* - Do not use the runtime mask when logfile is specified.fabient2010-08-031-0/+1

* - Reorganize code in 'plugin' to share log processing.fabient2010-02-111-23/+52
| | | | | | | | - Kcachegrind (calltree) support with assembly/source code mapping and call count estimator (-F). - Top mode for calltree and callgraph plugin (-T). MFC after: 1 month
* Add the -m option to pmcstat.attilio2008-11-251-0/+1
| | | | | | | | | This option prints the list of sampled PCs along with the function name, the start and end addresses of this where their live within. Reviewed by: jkoshy Tested by: gnn Sponsored by: Nokia
* Introduce pmcstat(8) changes for summarizing hwpmc(4) callchain records injkoshy2007-12-071-3/+13

* MFP4: Enhancements to pmcstat(8):jkoshy2007-04-271-4/+11
| | | | | | | | | | - Allow the "-t" option to take a regular expression naming command line processes to attach process PMCs to. - Update the manual page and add an example showing the use of the new functionality. - Update the (c) year on the affected source files.
* MFP4: Enhancements and bug-fixes to pmcstat(8):jkoshy2007-04-221-9/+17
| | | | | | | | | | | | | | | | - The '-c' option now takes a comma-separated list of CPU numbers, or a literal '*' denoting all CPUs in the system. Subsequent system PMCs are allocated on the CPUs so specified. Change the default behaviour to allocate system PMCs on all CPUs, not just CPU 0. Update the manual page and add an example of how to use the new functionality. - Attach PMCs to a (commandline) child process more reliably. This fixes a long standing bug in counting events incurred by short-lived processes.
* MFP4: Support for profiling dynamically loaded objects.jkoshy2006-03-261-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernel changes: Inform hwpmc of executable objects brought into the system by kldload() and mmap(), and of their removal by kldunload() and munmap(). A helper function linker_hwpmc_list_objects() has been added to "sys/kern/kern_linker.c" and is used by hwpmc to retrieve the list of currently loaded kernel modules. The unused `MAPPINGCHANGE' event has been deprecated in favour of separate `MAP_IN' and `MAP_OUT' events; this change reduces space wastage in the log. Bump the hwpmc's ABI version to "2.0.00". Teach hwpmc(4) to handle the map change callbacks. Change the default per-cpu sample buffer size to hold 32 samples (up from 16). Increment __FreeBSD_version. libpmc(3) changes: Update libpmc(3) to deal with the new events in the log file; bring the pmclog(3) manual page in sync with the code. pmcstat(8) changes: Introduce new options to pmcstat(8): "-r" (root fs path), "-M" (mapfile name), "-q"/"-v" (verbosity control). Option "-k" now takes a kernel directory as its argument but will also work with the older invocation syntax. Rework string handling in pmcstat(8) to use an opaque type for interned strings. Clean up ELF parsing code and add support for tracking dynamic object mappings reported by a v2.0.00 hwpmc(4). Report statistics at the end of a log conversion run depending on the requested verbosity level. Reviewed by: jhb, dds (kernel parts of an earlier patch) Tested by: gallatin (earlier patch)

- pmcstat(8) gprof output mode fixes: lib/libpmc/pmclog.{c,h}, sys/sys/pmclog.h: + Add a 'is_usermode' field to the PMCLOG_PCSAMPLE event + Add an 'entryaddr' field to the PMCLOG_PROCEXEC event, so that pmcstat(8) can determine where the runtime loader /libexec/ld-elf.so.1 is getting loaded. sys/kern/kern_exec.c: + Use a local struct to group the entry address of the image being exec()'ed and the process credential changed flag to the exec handling hook inside hwpmc(4). usr.sbin/pmcstat/*: + Support "-k kernelpath", "-D sampledir". + Implement the ELF bits of 'gmon.out' profile generation in a new file "pmcstat_log.c". Move all log related functions to this file. + Move local definitions and prototypes to "pmcstat.h" - Other bug fixes: + lib/libpmc/pmclog.c: correctly handle EOF in pmclog_read(). + sys/dev/hwpmc_mod.c: unconditionally log a PROCEXIT event to all attached PMCs when a process exits. + sys/sys/pmc.h: correct a function prototype. + Improve usage checks in pmcstat(8).
