Merge tag 'perf-core-for-mingo-4.18-20180606' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
perf stat:
- Display user and system time for workload targets (Jiri Olsa)
perf record:
- Enable arbitrary event names thru name= modifier (Alexey Budankov)
PowerPC:
- Add a python script for hypervisor call statistics (Ravi Bangoria)
Intel PT: (Adrian Hunter)
- Fix sync_switch INTEL_PT_SS_NOT_TRACING
- Fix decoding to accept CBR between FUP and corresponding TIP
- Fix MTC timing after overflow
- Fix "Unexpected indirect branch" error
perf test:
- record+probe_libc_inet_pton:
- To get the symbol table for dynamic
shared objects on ubuntu we need to pass the -D/--dynamic command line
option, unlike with the fedora distros (Arnaldo Carvalho de Melo)
- code-reading:
- Fix perf_env setup for PTI entry trampolines (Adrian Hunter)
- kmod-path:
- Add tests for vdso32 and vdsox32 (Adrian Hunter)
- Use header file util/debug.h (Thomas Richter)
perf annotate:
- Make the various UI backends (stdio, TUI, gtk) use more consistently
structs with annotation options as specified by the user (Arnaldo Carvalho de Melo)
- Move annotation specific knobs from the symbol_conf global kitchen
sink to the annotation option structs (Arnaldo Carvalho de Melo)
perf script:
- Add more PMU fields to python scripts event handler dict (Jin Yao)
Core:
- Fix misleading error for some unparsable events mentioning PMUs when
those are not involved in the problem (Jiri Olsa)
- Consider BSS symbols when processing /proc/kallsyms ('B' and 'b')
(Arnaldo Carvalho de Melo)
- Be more robust when trying to use per-symbol histograms, checking for
unlikely but possible cases where the space for the histograms wasn't
allocated, print a debug message for such cases (Arnaldo Carvalho de Melo)
- Fix symbol and object code resolution for vdso32 and vdsox32 (Adrian Hunter)
- No need to check for null when passing pointers to foo__get() style
refcount grabbing helpers, just like in the kernel and with free(),
its safe to pass a NULL pointer to avoid having to check it before
each and every foo__get() call (Arnaldo Carvalho de Melo)
- Remove some dead code (quote.[ch]) (Arnaldo Carvalho de Melo)
- Remove some needless globals, making them local (Arnaldo Carvalho de Melo)
- Reduce usage of symbol_conf.use_callchain, using other means of
finding out if callchains are in use or available for specific events,
as we evolved this codebase to allow requesting callchains for just
a subset of the monitored events. In time it will help polish
recording and showing mixed sets accross the various tools:
perf record -e cycles/call-graph=fp/,cache-misses/call-graph=dwarf/,instructions'
(Arnaldo Carvalho de Melo)
- Consider PTI entry trampolines in map__rip_2objdump() (Adrian Hunter)
