![]() Pull perf events update from Ingo Molnar: "On the kernel side there's few changes, the one that stands out is PEBS machine state sampling support on x86, by Stephane Eranian. On the tooling side: User visible tooling changes: - Don't open the DWARF info multiple times, keeping instead a dwfl handle in struct dso, greatly speeding up 'perf report' on powerpc. (Sukadev Bhattiprolu) - Introduce PARSE_OPT_DISABLED option flag and use it to avoid showing undersired options in tools that provides frontends to 'perf record', like sched, kvm, etc (Namhyung Kim) - Fallback to kallsyms when using the minimal 'ELF' loader (Arnaldo Carvalho de Melo) - Fix annotation with kcore (Adrian Hunter) - Support source line numbers in annotate using a hotkey (Andi Kleen) - Callchain improvements including: * Enable printing the srcline in the history * Make get_srcline fall back to sym+offset (Andi Kleen) - TUI hist_entry browser fixes, including showing missing overhead value for first level callchain. Detected comparing the output of --stdio/--gui (that matched) with --tui, that had this problem. (Namhyung Kim) - Support handling complete branch stacks as histograms (Andi Kleen) Tooling infrastructure changes: - Prep work for supporting per-pkg and snapshot counters in 'perf stat' (Jiri Olsa) - 'perf stat' refactorings, moving stuff from it to evsel.c to use in per-pkg/snapshot format changes (Jiri Olsa) - Add per-pkg format file parsing (Matt Fleming) - Clean up libelf feature support code (Namhyung Kim) - Add gzip decompression support for kernel modules (Namhyung Kim) - More prep patches for Intel PT, including a a thread stack and more stuff made available via the database export mechanism (Adrian Hunter) - More Intel PT work, including a facility to export sample data (comms, threads, symbol names, etc) in a database friendly way, with an script to use this to create a postgresql database. (Adrian Hunter) - Make sure that thread->mg->machine points to the machine where the thread exists (it was being set only for the kmaps kernel modules case, do it as well for the mmaps) and use it to shorten function signatures (Arnaldo Carvalho de Melo) ... and lots of other fixes and smaller improvements" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (91 commits) perf report: In branch stack mode use address history sorting perf report: Add --branch-history option perf callchain: Support handling complete branch stacks as histograms perf stat: Add support for snapshot counters perf stat: Add support for per-pkg counters perf tools: Remove perf_evsel__read interface perf stat: Use read_counter in read_counter_aggr perf stat: Make read_counter work over the thread dimension perf stat: Use perf_evsel__read_cb in read_counter perf tools: Add snapshot format file parsing perf tools: Add per-pkg format file parsing perf evsel: Introduce perf_evsel__read_cb function perf evsel: Introduce perf_counts_values__scale function perf evsel: Introduce perf_evsel__compute_deltas function perf tools: Allow to force redirect pr_debug to stderr. perf tools: Fix segfault due to invalid kernel dso access perf callchain: Make get_srcline fall back to sym+offset perf symbols: Move bfd_demangle stubbing to its only user perf callchain: Enable printing the srcline in the history perf tools: Collapse first level callchain entry if it has sibling ... |
