This allows avoiding a bunch of extra MSR reads in the PMI on Skylake. (Andi Kleen) Infrastructure: - Dump the stack when a 'perf test -v ' entry segfaults, so far we would have to run it under gdb with 'set follow-fork-mode child' set to get a proper backtrace (Arnaldo Carvalho de Melo) - Initialize the refcnt in 'struct thread' to 1 and fixup its users accordingly, so that we try to have the same refcount model accross the perf codebase (Arnaldo Carvalho de Melo) - More prep work for moving the subcmd infrastructure out of tools/perf/ and into tools/lib/subcmd/ to be used by other tools/ living utilities (Josh Poimboeuf) - Fix 'perf test' hist testcases when kptr_restrict is on (Namhyung Kim) Signed-off-by: Arnaldo Carvalho de Melo ---------------------------------------------------------------- Andi Kleen (1): perf evsel: Disable branch flags/cycles for --callgraph lbr Arnaldo Carvalho de Melo (3): perf tools: Use same signal handling strategy as 'record' perf test: Dump the stack when test segfaults when in verbose mode perf thread: Fix reference count initial state He Kuang (1): perf record: Support custom vmlinux path Josh Poimboeuf (9): perf build: Remove unnecessary line in Makefile.feature perf test: Add Build file to dependencies for llvm-src-*.c perf test: Remove tarpkg at end of test perf build: Fix 'make clean' perf build: Rename LIB_PATH -> API_PATH perf tools: Create pager.h perf tools: Remove check for unused PERF_PAGER_IN_USE perf tools: Move help_unknown_cmd() to its own file perf tools: Convert parse-options.c internal functions to static Namhyung Kim (1): perf test: Fix hist testcases when kptr_restrict is on Wang Nan (1): perf tools: Make options always available, even if required libs not linked tools/build/Makefile.feature | 1 - tools/perf/Documentation/perf-record.txt | 10 ++- tools/perf/Makefile.perf | 15 ++-- tools/perf/builtin-probe.c | 15 +++- tools/perf/builtin-record.c | 25 +++++- tools/perf/tests/Build | 6 +- tools/perf/tests/builtin-test.c | 3 + tools/perf/tests/hists_common.c | 5 +- tools/perf/tests/make | 3 +- tools/perf/util/Build | 1 + tools/perf/util/cache.h | 5 +- tools/perf/util/evsel.c | 14 +++- tools/perf/util/help-unknown-cmd.c | 103 +++++++++++++++++++++++ tools/perf/util/help-unknown-cmd.h | 0 tools/perf/util/help.c | 107 +----------------------- tools/perf/util/help.h | 3 + tools/perf/util/intel-pt.c | 4 +- tools/perf/util/machine.c | 19 +++-- tools/perf/util/pager.c | 8 +- tools/perf/util/pager.h | 7 ++ tools/perf/util/parse-options.c | 136 +++++++++++++++++++++++++++---- tools/perf/util/parse-options.h | 14 ++-- tools/perf/util/thread.c | 10 ++- tools/perf/util/util.c | 3 +- 24 files changed, 341 insertions(+), 176 deletions(-) create mode 100644 tools/perf/util/help-unknown-cmd.c create mode 100644 tools/perf/util/help-unknown-cmd.h create mode 100644 tools/perf/util/pager.h -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
