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.
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,
---
