Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar: "Kernel side changes: - Add Intel RAPL energy counter support (Stephane Eranian) - Clean up uprobes (Oleg Nesterov) - Optimize ring-buffer writes (Peter Zijlstra) Tooling side changes, user visible: - 'perf diff': - Add column colouring improvements (Ramkumar Ramachandra) - 'perf kvm': - Add guest related improvements, including allowing to specify a directory with guest specific /proc information (Dongsheng Yang) - Add shell completion support (Ramkumar Ramachandra) - Add '-v' option (Dongsheng Yang) - Support --guestmount (Dongsheng Yang) - 'perf probe': - Support showing source code, asking for variables to be collected at probe time and other 'perf probe' operations that use DWARF information. This supports only binaries with debugging information at this time, detached debuginfo (aka debuginfo packages) support should come in later patches (Masami Hiramatsu) - 'perf record': - Rename --no-delay option to --no-buffering, better reflecting its purpose and freeing up '--delay' to take the place of '--initial-delay', so that 'record' and 'stat' are consistent (Arnaldo Carvalho de Melo) - Default the -t/--thread option to no inheritance (Adrian Hunter) - Make per-cpu mmaps the default (Adrian Hunter) - 'perf report': - Improve callchain processing performance (Frederic Weisbecker) - Retain bfd reference to lookup source line numbers, greatly optimizing, among other use cases, 'perf report -s srcline' (Adrian Hunter) - Improve callchain processing performance even more (Namhyung Kim) - Add a perf.data file header window in the 'perf report' TUI, associated with the 'i' hotkey, providing a counterpart to the --header option in the stdio UI (Namhyung Kim) - 'perf script': - Add an option in 'perf script' to print the source line number (Adrian Hunter) - Add --header/--header-only options to 'script' and 'report', the default is not tho show the header info, but as this has been the default for some time, leave a single line explaining how to obtain that information (Jiri Olsa) - Add options to show comm, fork, exit and mmap PERF_RECORD_ events (Namhyung Kim) - Print callchains and symbols if they exist (David Ahern) - 'perf timechart' - Add backtrace support to CPU info - Print pid along the name - Add support for CPU topology - Add new option --highlight'ing threads, be it by name or, if a numeric value is provided, that run more than given duration (Stanislav Fomichev) - 'perf top': - Make 'perf top -g' refer to callchains, for consistency with other tools (David Ahern) - 'perf trace': - Handle old kernels where the "raw_syscalls" tracepoints were called plain "syscalls" (David Ahern) - Remove thread summary coloring, by Pekka Enberg. - Honour -m option in 'trace', the tool was offering the option to set the mmap size, but wasn't using it when doing the actual mmap on the events file descriptors (Jiri Olsa) - generic: - Backport libtraceevent plugin support (trace-cmd repository, with plugins for jbd2, hrtimer, kmem, kvm, mac80211, sched_switch, function, xen, scsi, cfg80211 (Jiri Olsa) - Print session information only if --stdio is given (Namhyung Kim) Tooling side changes, developer visible (plumbing): - Improve 'perf probe' exit path, release resources (Masami Hiramatsu) - Improve libtraceevent plugins exit path, allowing the registering of an unregister handler to be called at exit time (Namhyung Kim) - Add an alias to the build test makefile (make -C tools/perf build-test) (Namhyung Kim) - Get rid of die() and friends (good riddance!) in libtraceevent (Namhyung Kim) - Fix cross build problems related to pkgconfig and CROSS_COMPILE not being propagated to the feature tests, leading to features being tested in the host and then being enabled on the target (Mark Rutland) - Improve forked workload error reporting by sending the errno in the signal data queueing integer field, using sigqueue and by doing the signal setup in the evlist methods, removing open coded equivalents in various tools (Arnaldo Carvalho de Melo) - Do more auto exit cleanup chores in the 'evlist' destructor, so that the tools don't have to all do that sequence (Arnaldo Carvalho de Melo) - Pack 'struct perf_session_env' and 'struct trace' (Arnaldo Carvalho de Melo) - Add test for building detached source tarballs (Arnaldo Carvalho de Melo) - Move some header files (tools/perf/ to tools/include/ to make them available to other tools/ dwelling codebases (Namhyung Kim) - Move logic to warn about kptr_restrict'ed kernels to separate function in 'report' (Arnaldo Carvalho de Melo) - Move hist browser selection code to separate function (Arnaldo Carvalho de Melo) - Move histogram entries collapsing to separate function (Arnaldo Carvalho de Melo) - Introduce evlist__for_each() & friends (Arnaldo Carvalho de Melo) - Automate setup of FEATURE_CHECK_(C|LD)FLAGS-all variables (Jiri Olsa) - Move arch setup into seprate Makefile (Jiri Olsa) - Make libtraceevent install target quieter (Jiri Olsa) - Make tests/make output more compact (Jiri Olsa) - Ignore generated files in feature-checks (Chunwei Chen) - Introduce pevent_filter_strerror() in libtraceevent, similar in purpose to libc's strerror() function (Namhyung Kim) - Use perf_data_file methods to write output file in 'record' and 'inject' (Jiri Olsa) - Use pr_*() functions where applicable in 'report' (Namhyumg Kim) - Add 'machine' 'addr_location' struct to have full picture (machine, thread, map, symbol, addr) for a (partially) resolved address, reducing function signatures (Arnaldo Carvalho de Melo) - Reduce code duplication in the histogram entry creation/insertion (Arnaldo Carvalho de Melo) - Auto allocate annotation histogram data structures (Arnaldo Carvalho de Melo) - No need to test against NULL before calling free, also set freed memory in struct pointers to NULL, to help fixing use after free bugs (Arnaldo Carvalho de Melo) - Rename some struct DSO binary_type related members and methods, to clarify its purpose and need for differentiation (symtab_type, ie one is about the files .text, CFI, etc, i.e. its binary contents, and the other is about where the symbol table came from (Arnaldo Carvalho de Melo) - Convert to new topic libraries, starting with an API one (sysfs, debugfs, etc), renaming liblk in the process (Borislav Petkov) - Get rid of some more panic() like error handling in libtraceevent. (Namhyung Kim) - Get rid of panic() like calls in libtraceevent (Namyung Kim) - Start carving out symbol parsing routines (perf, just moving routines to topic files in tools/lib/symbol/, tools that want to use it need to integrate it directly, ie no tools/lib/symbol/Makefile is provided (Arnaldo Carvalho de Melo) - Assorted refactoring patches, moving code around and adding utility evlist methods that will be used in the IPT patchset (Adrian Hunter) - Assorted mmap_pages handling fixes (Adrian Hunter) - Several man pages typo fixes (Dongsheng Yang) - Get rid of several die() calls in libtraceevent (Namhyung Kim) - Use basename() in a more robust way, to avoid problems related to different system library implementations for that function (Stephane Eranian) - Remove open coded management of short_name_allocated member (Adrian Hunter) - Several cleanups in the "dso" methods, constifying some parameters and renaming some fields to clarify its purpose (Arnaldo Carvalho de Melo) - Add per-feature check flags, fixing libunwind related build problems on some architectures (Jean Pihet) - Do not disable source line lookup just because of one failure. (Adrian Hunter) - Several 'perf kvm' man page corrections (Dongsheng Yang) - Correct the message in feature-libnuma checking, swowing the right devel package names for various distros (Dongsheng Yang) - Polish 'readn()' function and introduce its counterpart, 'writen()' (Jiri Olsa) - Start moving timechart state from global variables to a 'perf_tool' derived 'timechart' struct (Arnaldo Carvalho de Melo) ... and lots of fixes and improvements I forgot to list" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (282 commits) perf tools: Remove unnecessary callchain cursor state restore on unmatch perf callchain: Spare double comparison of callchain first entry perf tools: Do proper comm override error handling perf symbols: Export elf_section_by_name and reuse perf probe: Release all dynamically allocated parameters perf probe: Release allocated probe_trace_event if failed perf tools: Add 'build-test' make target tools lib traceevent: Unregister handler when xen plugin is unloaded tools lib traceevent: Unregister handler when scsi plugin is unloaded tools lib traceevent: Unregister handler when jbd2 plugin is is unloaded tools lib traceevent: Unregister handler when cfg80211 plugin is unloaded tools lib traceevent: Unregister handler when mac80211 plugin is unloaded tools lib traceevent: Unregister handler when sched_switch plugin is unloaded tools lib traceevent: Unregister handler when kvm plugin is unloaded tools lib traceevent: Unregister handler when kmem plugin is unloaded tools lib traceevent: Unregister handler when hrtimer plugin is unloaded tools lib traceevent: Unregister handler when function plugin is unloaded tools lib traceevent: Add pevent_unregister_print_function() tools lib traceevent: Add pevent_unregister_event_handler() tools lib traceevent: fix pointer-integer size mismatch ...
