This also includes some bugfixes and cleanups. E.g. --list/--funcs accepts filter rules. ---- # ./perf probe -l vfs\* probe:vfs_read (on vfs_read@ksrc/linux-3/fs/read_write.c) # ./perf probe -l \*libc:\* probe_libc:malloc (on __libc_malloc@malloc/malloc.c in /usr/lib64/libc-2.17.so) ---- ---- # ./perf probe -F *kmalloc __kmalloc devm_kmalloc mempool_kmalloc sg_kmalloc sock_kmalloc ---- Also, --del accepts filter rules too which is more flexible than simple wildcard. ---- # ./perf probe -d 'vfs*|malloc' Removed event: probe:vfs_read Removed event: probe_libc:malloc ---- Thank you, --- Masami Hiramatsu (8): [BUGFIX] perf probe: Make --funcs option exclusive [BUGFIX] perf probe: Remove all probes matches given pattern at once perf probe: Accept multiple filter options perf probe: Accept filter argument for --list perf probe: Allow to use filter on --del command perf probe: Accept filter argument for --funcs perf probe: Remove redundant cleanup of params.filter perf probe: Cleanup and consolidate command parsers tools/perf/Documentation/perf-probe.txt | 11 +- tools/perf/builtin-probe.c | 162 +++++++++++++++---------------- tools/perf/util/probe-event.c | 113 +++++++++------------- tools/perf/util/probe-event.h | 4 - tools/perf/util/strfilter.c | 100 +++++++++++++++++++ tools/perf/util/strfilter.h | 22 ++++ 6 files changed, 258 insertions(+), 154 deletions(-) -- Masami HIRAMATSU Linux Technology Research Center, System Productivity Research Dept.
