Hi,
Here is a series of patches which improves perf-probe to add filtering features for --list,--del and --funcs. This also includes some bugfixes and cleanups.
I've fixed some patches according to Namhyung's review(Thanks!), and splitted the strfilter related patches.
Note that first 2 bugfixes are removed from this series, those are already picked by Arnaldo.
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 ----
Changes in v3: - [1/8] Split strfilter__or() and add strfilter__and() from v2 [3/8]. Also rename strfilter__add() to strfilter__append(). - [2/8] Split strfilter__string from v2 [5/8].
Changes in v2: - [2/8] Fix to check errors except -ENOENT on deleting events. - [5/8] Ditto. - [5/8] Fix to check memory allocation error in strfilter__string. - [5/8] Fix to check errors of strfilter__string for verifying given filter.
Thank you,
---
