Support generating cross arch probes, i.e. if you specify a vmlinux file for different arch than the one in the host machine, $ perf probe --definition function_name args will generate the probe definition string needed to append to the target machine /sys/kernel/debug/tracing/kprobes_events file, using scripting (Masami Hiramatsu). - Make 'perf probe' skip the function prologue in uprobes if program compiled without optimization, using the same strategy as gdb and systemtap uses, fixing a bug where: $ perf probe -x ./test 'foo i' When 'foo(42)' was used on the "./test" executable would produce i=0 instead of the expected i=42 (Ravi Bangoria) - Demangle symbols for synthesized @plt entries too (Millian Wolff) Documentation: - Show default report configuration in 'perf config' example and docs (Millian Wolff) Infrastructure: - Make 'perf test vmlinux' tolerate the symbol aliasing pruning done when loading kallsyms and vmlinux (Arnaldo Carvalho de Melo) - Improve output of 'perf test vmlinux' test, to help identify on the verbose output which lines are warning and which are errors (Arnaldo Carvalho de Melo) - Prep work to stop having to pass symbol_filter_t to lots of functions, simplifying symtab loading routines (Arnaldo Carvalho de Melo) - Honor symbol_conf.allow_aliases when loading kallsyms as well, it was using it only when loading vmlinux files (Arnaldo Carvalho de Melo) - Fixup symbol->end before doing alias pruning when loading symbol tables (Arnaldo Carvalho de Melo) - Fix error handling of lzma kernel module decompression (Shawn Lin) Signed-off-by: Arnaldo Carvalho de Melo ---------------------------------------------------------------- Arnaldo Carvalho de Melo (8): perf annotate: Initialize the priv are in symbol__new() perf symbols: Rename ->ignore to ->idle perf probe: Do not use map_load filters for function perf test vmlinux: Clarify which -v lines are errors or warning perf test vmlinux: Avoid printing headers for empty lists perf test vmlinux: Tolerate symbol aliases perf symbols: Check symbol_conf.allow_aliases for kallsyms loading too perf symbols: Fixup symbol sizes before picking best ones Masami Hiramatsu (5): perf probe: Remove unused tracing_dir variable perf probe: Show trace event definition perf probe: Ignore vmlinux buildid if offline kernel is given perf probe: Support probing on offline cross-arch binary perf probe: Ignore vmlinux Build-id when offline vmlinux given Milian Wolff (2): perf symbols: Demangle symbols for synthesized @plt entries. perf config: Show default report configuration in example and docs Ravi Bangoria (3): perf probe: Add helper function to check if probe with variable perf uprobe: Skip prologue if program compiled without optimization perf probe: Move dwarf specific functions to dwarf-aux.c Shawn Lin (1): perf tools: Fix error handling of lzma decompression tools/perf/Documentation/perf-config.txt | 8 + tools/perf/Documentation/perf-probe.txt | 9 ++ tools/perf/Documentation/perfconfig.example | 9 ++ tools/perf/arch/arm/include/dwarf-regs-table.h | 9 ++ tools/perf/arch/arm64/include/dwarf-regs-table.h | 13 ++ tools/perf/arch/powerpc/include/dwarf-regs-table.h | 27 ++++ tools/perf/arch/s390/include/dwarf-regs-table.h | 8 + tools/perf/arch/sh/include/dwarf-regs-table.h | 25 +++ tools/perf/arch/sparc/include/dwarf-regs-table.h | 18 +++ tools/perf/arch/x86/include/dwarf-regs-table.h | 14 ++ tools/perf/arch/xtensa/include/dwarf-regs-table.h | 8 + tools/perf/builtin-annotate.c | 7 +- tools/perf/builtin-probe.c | 35 +++- tools/perf/builtin-report.c | 6 +- tools/perf/builtin-top.c | 8 +- tools/perf/tests/vmlinux-kallsyms.c | 44 +++-- tools/perf/util/Build | 1 + tools/perf/util/annotate.c | 7 -
