Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar: "The main kernel side changes were:
- uprobes enhancements (Masami Hiramatsu)
- Uncore group events enhancements (David Carrillo-Cisneros)
- x86 Intel: Add support for Skylake server uncore PMUs (Kan Liang)
- x86 Intel: LBR cleanups and enhancements, for better branch annotation tracking (Peter Zijlstra)
- x86 Intel: Add support for PTWRITE and power event tracing (Alexander Shishkin)
- ... various fixes, cleanups and smaller enhancements.
Lots of tooling changes - a couple of highlights:
- Support event group view with hierarchy mode in 'perf top' and 'perf report' (Namhyung Kim)
e.g.:
$ perf record -e '{cycles,instructions}' make $ perf report --hierarchy --stdio ... # Overhead Command / Shared Object / Symbol # ...................... .................................. ... 25.74% 27.18%sh 19.96% 24.14%libc-2.24.so 9.55% 14.64%[.] __strcmp_sse2 1.54% 0.00%[.] __tfind 1.07% 1.13%[.] _int_malloc 0.95% 0.00%[.] __strchr_sse2 0.89% 1.39%[.] __tsearch 0.76% 0.00%[.] strlen
- Add branch stack / basic block info to 'perf annotate --stdio', where for each branch, we add an asm comment after the instruction with information on how often it was taken and predicted. See example with color output at:
http://vger.kernel.org/~acme/perf/annotate_basic_blocks.png
(Peter Zijlstra)
- Add support for using symbols in address filters with Intel PT and ARM CoreSight (hardware assisted tracing facilities) (Adrian Hunter, Mathieu Poirier)
- Add support for interacting with Coresight PMU ETMs/PTMs, that are IP blocks to perform hardware assisted tracing on a ARM CPU core (Mathieu Poirier)
- Support generating cross arch probes, i.e. if you specify a vmlinux file for different arch than the one in the host machine,
$ perf probe --definition function_name args
will generate the probe definition string needed to append to the target machine /sys/kernel/debug/tracing/kprobes_events file, using scripting (Masami Hiramatsu).
- Allow configuring the default 'perf report -s' sort order in ~/.perfconfig, for instance, "sym,dso" may be more fitting for kernel developers. (Arnaldo Carvalho de Melo)
- ... plus lots of other changes, refactorings, features and fixes"
* 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (149 commits) perf tests: Add dwarf unwind test for powerpc perf probe: Match linkage name with mangled name perf probe: Fix to cut off incompatible chars from group name perf probe: Skip if the function address is 0 perf probe: Ignore the error of finding inline instance perf intel-pt: Fix decoding when there are address filters perf intel-pt: Enable decoder to handle TIP.PGD with missing IP perf intel-pt: Read address filter from AUXTRACE_INFO event perf intel-pt: Record address filter in AUXTRACE_INFO event perf intel-pt: Add a helper function for processing AUXTRACE_INFO perf intel-pt: Fix missing error codes processing auxtrace_info perf intel-pt: Add support for recording the max non-turbo ratio perf intel-pt: Fix snapshot overlap detection decoder errors perf probe: Increase debug level of SDT debug messages perf record: Add support for using symbols in address filters perf symbols: Add dso__last_symbol() perf record: Fix error paths perf record: Rename label 'out_symbol_exit' perf script: Fix vanished idle symbols perf evsel: Add support for address filters ...

perf intel-pt: Add support for recording the max non-turbo ratio
Previously the maximum non-turbo ratio was calculated from TSC assuming a 100 MHz multiplier which is correct for current hardware supporting Intel PT. However more recent kernels also now export the value, so use that in preference to the calculated value.

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar: "Main perf kernel side changes:
- uprobes updates/fixes. (Oleg Nesterov)
- Add PERF_RECORD_SWITCH to indicate context switches and use it in tooling. (Adrian Hunter)
- Support BPF programs attached to uprobes and first steps for BPF tooling support. (Wang Nan)

Main perf tooling side changes:
- Support Intel PT in several tools, enabling the use of the processor trace feature introduced in Intel Broadwell processors: (Adrian Hunter)

- Add support for using several Intel PT features (CYC, MTC packets), the relevant documentation was updated in: tools/perf/Documentation/intel-pt.txt briefly describing those packets, its purposes, how to configure them in the event config terms and relevant external documentation for further reading. (Adrian Hunter)
- Introduce support for probing at an absolute address, for user and kernel 'perf probe's, useful when one have the symbol maps on a developer machine but not on an embedded system. (Wang Nan)
- Add Intel BTS support, with a call-graph script to show it and PT in use in a GUI using 'perf script' python scripting with postgresql and Qt. (Adrian Hunter)
- Allow selecting the type of callchains per event, including disabling callchains in all but one entry in an event list, to save space, and also to ask for the callchains collected in one event to be used in other events. (Kan Liang)
- Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho de Melo) * A bunch more translate file/pathnames from pointers to strings. * Convert numbers to strings for the 'keyctl' syscall 'option' arg. * Add missing 'clockid' entries.
- Introduce 'srcfile' sort key: (Andi Kleen)
# perf record -F 10000 usleep 1 # perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile <SNIP> # Overhead Source File 26.49% copy_page_64.S 5.49% signal.c 0.51% msr.h #
It can be combined with other fields, for instance, experiment with '-s srcfile,symbol'.
There are some oddities in some distros and with some specific DSOs, being investigated, so your mileage may vary.
- Support per-event 'freq' term: (Namhyung Kim)
$ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1 $ perf evlist -F cpu/instructions,freq=1234/: sample_freq=1234 cycles: sample_period=1000 $
- Deref sys_enter pointer args with contents from probe:vfs_getname, showing pathnames instead of pointers in many syscalls in 'perf trace'. (Arnaldo Carvalho de Melo)
- Stop collecting /proc/kallsyms in perf.data files, saving about 4.5MB on a typical x86-64 system, use the the symbol resolution routines used in all the other tools (report, top, etc) now that we can ask libtraceevent to use perf's symbol resolution code. (Arnaldo Carvalho de Melo)
- Allow filtering out of perf's PID via 'perf record --exclude-perf'. (Wang Nan)
- 'perf trace' now supports syscall groups, like strace, i.e:
$ trace -e file touch file
Will expand 'file' into multiple, file related, syscalls. More work needed to add extra groups for other syscall groups, and also to complement what was added for the 'file' group, included as a proof of concept. (Arnaldo Carvalho de Melo)
- Add lock_pi stresser to 'perf bench futex', to test the kernel code related to FUTEX_(UN)LOCK_PI. (Davidlohr Bueso)
- Let user have timestamps with per-thread recording in 'perf record' (Adrian Hunter)
- ... and tons of other changes, see the shortlog and the Git log for details"
