perf test shell: Check if 'perf probe' is available, skip tests if not
Add a library function that checks if 'perf probe' is built into the
tool being tested, skipping tests that need it.
Testing it on a system after removing the library needed to build
'probe' as a perf subcommand:
# perf test ping vfs_getname
59: Use vfs_getname probe to get syscall args filenames : Skip
60: probe libc's inet_pton & backtrace it with ping : Skip
61: Check open filename arg using perf trace + vfs_getname: Skip
62: Add vfs_getname probe to get syscall args filenames : Skip
# perf probe
perf: 'probe' is not a perf-command. See 'perf --help'.
#
Now reinstalling elfutils-libelf-devel on this Fedora 26 system to
rebuild perf and then retest this:
# perf test ping vfs_getname
60: Use vfs_getname probe to get syscall args filenames : Ok
61: probe libc's inet_pton & backtrace it with ping : Ok
62: Check open filename arg using perf trace + vfs_getname: Ok
63: Add vfs_getname probe to get syscall args filenames : Ok
