Pull perf updates from Ingo Molnar: "The main changes in this cycle on the kernel side were: - CPU PMU and uncore driver updates to Intel Snow Ridge, IceLake, KabyLake, AmberLake and WhiskeyLake CPUs. - Rework the MSR probing infrastructure to make it more robust, make it work better on virtualized systems and to better expose it on sysfs. - Rework PMU attributes group support based on the feedback from Greg. The core sysfs patch that adds sysfs_update_groups() was acked by Greg. There's a lot of perf tooling changes as well, all around the place: - vendor updates to Intel, cs-etm (ARM), ARM64, s390, - various enhancements to Intel PT tooling support: - Improve CBR (Core to Bus Ratio) packets support. - Export power and ptwrite events to sqlite and postgresql. - Add support for decoding PEBS via PT packets. - Add support for samples to contain IPC ratio, collecting cycles information from CYC packets, showing the IPC info periodically - Allow using time ranges - lots of updates to perf pmu, perf stat, perf trace, eBPF support, perf record, perf diff, etc. - please see the shortlog and Git log for details" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (252 commits) tools arch x86: Sync asm/cpufeatures.h with the with the kernel tools build: Check if gettid() is available before providing helper perf jvmti: Address gcc string overflow warning for strncpy() perf python: Remove -fstack-protector-strong if clang doesn't have it perf annotate TUI browser: Do not use member from variable within its own initialization perf tests: Fix record+probe_libc_inet_pton.sh for powerpc64 perf evsel: Do not rely on errno values for precise_ip fallback perf thread: Allow references to thread objects after machine__exit() perf header: Assign proper ff->ph in perf_event__synthesize_features() tools arch kvm: Sync kvm headers with the kernel sources perf script: Allow specifying the files to process guest samples perf tools metric: Don't include duration_time in group perf list: Avoid extra : for --raw metrics perf vendor events intel: Metric fixes for SKX/CLX perf tools: Fix typos / broken sentences perf jevents: Add support for Hisi hip08 L3C PMU aliasing perf jevents: Add support for Hisi hip08 HHA PMU aliasing perf jevents: Add support for Hisi hip08 DDRC PMU aliasing perf pmu: Support more complex PMU event aliasing perf diff: Documentation -c cycles option ...

tools: bpftool: add "prog run" subcommand to test-run programs

2019-07-05T21:48:07Z

Add a new "bpftool prog run" subcommand to run a loaded program on input data (and possibly with input context) passed by the user. Print output data (and output context if relevant) into a file or into the console. Print return value and duration for the test run into the console. A "repeat" argument can be passed to run the program several times in a row. The command does not perform any kind of verification based on program type (Is this program type allowed to use an input context?) or on data consistency (Can I work with empty input data?), this is left to the kernel. Example invocation: # perl -e 'print "\x0" x 14' | ./bpftool prog run \ pinned /sys/fs/bpf/sample_ret0 \ data_in - data_out - repeat 5 0000000 0000 0000 0000 0000 0000 0000 0000 | ........ ...... Return value: 0, duration (average): 260ns When one of data_in or ctx_in is "-", bpftool reads from standard input, in binary format. Other formats (JSON, hexdump) might be supported (via an optional command line keyword like "data_fmt_in") in the future if relevant, but this would require doing more parsing in bpftool. v2: - Fix argument names for function check_single_stdin().

tools lib: Move argv_{split,free} from tools/perf/util/

2019-07-02T01:50:40Z

This came from the kernel lib/argv_split.c, so move it to tools/lib/argv_split.c, to get it closer to the kernel structure. We need to audit the usage of argv_split() to figure out if it is really necessary to do have one allocation per argv[] entry, looking at one of its users I guess that is not the case and we probably are even leaking those allocations by not using argv_free() judiciously, for later. With this we further remove stuff from tools/perf/util/, reducing the perf specific codebase and encouraging other tools/ code to use these routines so as to keep the style and constructs used with the kernel.

tools lib: Adopt strim() from the kernel

2019-06-26T14:50:16Z

Since we're working on moving stuff out of tools/perf/util/ to tools/lib/, take the opportunity to adopt routines from the kernel that are equivalent, so that tools/ code look more like the kernel.
