Subject: perf probe -F with wildcards
Date: Thu, 14 Jul 2016 21:16:41 -0300 [thread overview]
Message-ID: <20160715001641.GD3021@kernel.org> (raw)
Hi Masami,
I think this worked at some point?
[root@jouet acme]# perf probe -F | tail
zswap_frontswap_init
zswap_frontswap_invalidate_area
zswap_frontswap_invalidate_page
zswap_frontswap_load
zswap_frontswap_store
zswap_pool_create
zswap_pool_current
zswap_update_total_size
zswap_writeback_entry
zswap_zpool_param_set
[root@jouet acme]# perf probe -F rt_sp*
no symbols found in [kernel.kallsyms], maybe install a debug package?
Failed to load symbols in kernel
[root@jouet acme]# perf probe -F rt_sp\*
no symbols found in [kernel.kallsyms], maybe install a debug package?
Failed to load symbols in kernel
[root@jouet acme]#
I.e. the second message is misleading :-\
