Merge tag 'perf-core-for-mingo-5.2-20190402' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/corePull perf/core improvements and fixes from Arnaldo:perf record: Alexey Budankov: - Implement --mmap-flush= option, to control a threshold for draining the mmap ring buffers and consequently the size of the write calls to the output, be it perf.data, pipe mode or soon a compressor that with bigger buffers will do a better job before dumping compressed data into a new perf.data content mode, which is in the final steps of reviewing and testing.perf trace: Arnaldo Carvalho de Melo: - Add 'string' event alias to select syscalls with string args, i.e. for testing the BPF program used to copy those strings, allow for: # perf trace -e string To select all the syscalls that have things like pathnames. - Use a PERCPU_ARRAY BPF map to copy more string bytes than what is possible using the BPF stack, just like pioneered by the sysdig tool.Feature detection: Alexey Budankov: - Implement libzstd feature check, which is a library that provides a uniform API to various compression formats, will be used in 'perf record', see note about --mmap-flush feature.perf stat: Andi Kleen: - Implement a tool specific 'duration_time' event to allow showing the "time elapsed" line in the default 'perf stat' output as one of the events that can be asked for when using --field-separator and other script consumable outputs.Intel vendor events (JSON files): Andi Kleen: - Update metrics from TMAM 3.5. - Update events: Bonnell to V4 Broadwell-DE to v7 Broadwell to v23 BroadwellX to v14 GoldmontPlus to v1.01 Goldmont to v13 Haswell to v28 HaswellX to v20 IvyBridge to v21 IvyTown to v20 JakeTown to v20 KnightsLanding to v9 SandyBridge to v16 Silvermont to v14 Skylake to v42 SkylakeX to v1.12IBM S/390 vendor events (JSON): Thomas Richter: - Fix s390 counter long description for L1D_RO_EXCL_WRITES.tools lib traceevent: Steven Rostedt (Red Hat): - Add more debugging to see various internal ring buffer entries. Steven Rostedt (VMWare): - Handle trace_printk() "%px". - Add mono clocks to be parsed in seconds. - Removed unneeded !! and return parenthesis. Tzvetomir Stoyanov : - Implement a new API, tep_list_events_copy(). - Implement new traceevent APIs for accessing struct tep_handler fields. - Remove tep filter trivial APIs, not used anymore. - Remove call to exit() from tep_filter_add_filter_str(), library routines shouldn't kill tools using it. - Make traceevent APIs more consistent.Signed-off-by: Arnaldo Carvalho de Melo List of files: /linux/tools/perf/trace/strace/groups/string

perf trace: Add 'string' event alias to select syscalls with string argsWill be used in conjunction with the change to augmented_raw_syscalls.cin the next cset that adds all syscalls with a first or second argstring.With just what we have in the syscall tracepoints we get: # perf trace -e string ls > /dev/null ?
