This updates includes --line option support which you are waiting for :-). For kprobe-tracer, I decided to drop $argN support, because the ABI for each function strongly depends on not only the architecture but also the API of the function and gcc options. Anyway, we already have perf-probe which allows us to find register/memory assignment of each arguments. Here are updated todo list. Long-term TODOs (future features): - Support lazy string matching(glob?) for selecting probing line - Support sys_perf_counter_open (for non-root users) - Support tracing static variables (non global) - Support variable types from debuginfo (e.g. char, int, ...) - Support fields of data structures (var->field) - Support array (var[N]) - Support dynamic array-indexing (var[var2]) - Support string/dynamic arrays (*var, var[N..M]) - Support force type-casting ((type)var) - Support the type of return value Miscs: - Better support for probes on modules - Move onto libdw/libdwfl - Storing file name/line number information in the kernel for listing events Thank you, --- Masami Hiramatsu (8): perf probe: Support --line option to show probable source-code lines perf tools: Enhance glob string matching perf tools: Support tracepoint glob matching perf probe: Show probe list in pager [CLEANUP] perf probe: Remove newline from die() x86/ptrace: Remove unused regs_get_argument_nth API tracing/kprobe: Drop function argument access syntax tracing/kprobe: Update example output in documentation Documentation/trace/kprobetrace.txt | 48 ++++--- arch/x86/include/asm/ptrace.h | 4 - arch/x86/kernel/ptrace.c | 24 ---- kernel/trace/trace_kprobe.c | 18 --- tools/perf/Documentation/perf-probe.txt | 20 +++ tools/perf/builtin-probe.c | 80 ++++++++++-- tools/perf/util/parse-events.c | 11 +- tools/perf/util/probe-event.c | 103 ++++++++++++++++ tools/perf/util/probe-event.h | 2 tools/perf/util/probe-finder.c | 203 +++++++++++++++++++++++++++++-- tools/perf/util/probe-finder.h | 31 +++++ tools/perf/util/string.c | 65 +++++++++- 12 files changed, 507 insertions(+), 102 deletions(-) -- Masami Hiramatsu Software Engineer Hitachi Computer Products (America), Inc.
