perf check: Introduce 'check' subcommand
Currently the presence of a feature is checked with a combination of
perf version --build-options and greps, such as:
perf version --build-options | grep " on .* HAVE_FEATURE"
Instead of this, introduce a subcommand "perf check feature", with which
scripts can test for presence of a feature, such as:
perf check feature HAVE_FEATURE
'perf check feature' command is expected to have exit status of 0 if
feature is built-in, and 1 if it's not built-in or if feature is not known.
Multiple features can also be passed as a comma-separated list, in which
case the exit status will be 1 only if all of the passed features are
built-in. For example, with below command, it will have exit status of 0
only if both libtraceevent and bpf are enabled, else 1 in all other cases
perf check feature libtraceevent,bpf
The arguments are case-insensitive.
An array 'supported_features' has also been introduced that can be used by
other commands like 'perf version --build-options', so that new features
can be added in one place, with the array
Committer testing:
$ perf check feature libtraceevent,bpf
libtraceevent: [ on ] # HAVE_LIBTRACEEVENT
bpf: [ on ] # HAVE_LIBBPF_SUPPORT
$ perf check feature libtraceevent
libtraceevent: [ on ] # HAVE_LIBTRACEEVENT
$ perf check feature bpf
bpf: [ on ] # HAVE_LIBBPF_SUPPORT
$ perf check -q feature bpf && echo "BPF support is present"
BPF support is present
$ perf check -q feature Bogus && echo "Bogus support is present"

perf build: Use libtraceevent from the system
Remove the LIBTRACEEVENT_DYNAMIC and LIBTRACEFS_DYNAMIC make command
line variables.
If libtraceevent isn't installed or NO_LIBTRACEEVENT=1 is passed to the
build, don't compile in libtraceevent and libtracefs support.
This also disables CONFIG_TRACE that controls "perf trace".
CONFIG_LIBTRACEEVENT is used to control enablement in Build/Makefiles,
HAVE_LIBTRACEEVENT is used in C code.
Without HAVE_LIBTRACEEVENT tracepoints are disabled and as such the
commands kmem, kwork, lock, sched and timechart are removed. The
majority of commands continue to work including "perf test".
Committer notes:
Fixed up a tools/perf/util/Build reject and added:
#include <traceevent/event-parse.h>
to tools/perf/util/scripting-engines/trace-event-perl.c.

Had to tweak tools/perf/util/setup.py to make sure the python binding
shared object links with libtraceevent if -DHAVE_LIBTRACEEVENT is
present in CFLAGS.
Building with NO_LIBTRACEEVENT=1 uncovered some more build failures:
- Make building of data-convert-bt.c to CONFIG_LIBTRACEEVENT=y
- perf-$(CONFIG_LIBTRACEEVENT) += scripts/
- bpf_kwork.o needs also to be dependent on CONFIG_LIBTRACEEVENT=y
- The python binding needed some fixups and util/trace-event.c can't be
built and linked with the python binding shared object, so remove it
in tools/perf/util/setup.py and exclude it from the list of
dependencies in the python/perf.so Makefile.perf target.
Building without libtraceevent-devel installed uncovered more build
failures:
- The python binding tools/perf/util/python.c was assuming that
traceevent/parse-events.h was always available, which was the case
when we defaulted to using the in-kernel tools/lib/traceevent/ files,
now we need to enclose it under ifdef HAVE_LIBTRACEEVENT, just like
the other parts of it that deal with tracepoints.
- We have to ifdef the rules in the Build files with
CONFIG_LIBTRACEEVENT=y to build builtin-trace.c and
tools/perf/trace/beauty/ as we only ifdef setting CONFIG_TRACE=y when
setting NO_LIBTRACEEVENT=1 in the make command line, not when we don't
detect libtraceevent-devel installed in the system. Simplification here
to avoid these two ways of disabling builtin-trace.c and not having
CONFIG_TRACE=y when libtraceevent-devel isn't installed is the clean
way.
From Athira:
<quote>
tools/perf/arch/powerpc/util/Build
-perf-y += kvm-stat.o
+perf-$(CONFIG_LIBTRACEEVENT) += kvm-stat.o
</quote>
Then, ditto for arm64 and s390, detected by container cross build tests.
- s/390 uses test__checkevent_tracepoint() that is now only available if
HAVE_LIBTRACEEVENT is defined, enclose the callsite with ifder HAVE_LIBTRACEEVENT.
Also from Athira:
<quote>
With this change, I could successfully compile in these environment:
- Without libtraceevent-devel installed
- With libtraceevent-devel installed
- With “make NO_LIBTRACEEVENT=1”
</quote>
Then, finally rename CONFIG_TRACEEVENT to CONFIG_LIBTRACEEVENT for
consistency with other libraries detected in tools/perf/.

perf trace: Support 'strace' syscall event groups
I.e.:
$ cat ~/share/perf-core/strace/groups/file
access
chmod
creat
execve
faccessat
getcwd
lstat
mkdir
open
openat
quotactl
readlink
rename
rmdir
stat
statfs
symlink
unlink
$
Then, on a quiet desktop, try running this and then moving your mouse to
see the deluge of mouse related activity:
# perf probe 'vfs_getname=getname_flags:72 pathname=filename:string'
Added new event:
probe:vfs_getname (on getname_flags:72 with pathname=filename:string)
You can now use it in all perf tools, such as:
perf record -e probe:vfs_getname -aR sleep 1
#
# trace --ev probe:vfs_getname --filter-pids 2232 -e file
0.042 (0.042 ms): mousetweaks/2235 open(filename: 0x14e3910, mode: 438 ) ...
0.042 ( ): probe:vfs_getname:(ffffffff812230bc) pathname="/home/acme/.icons/Adwaita/cursors/xterm")
0.100 (0.100 ms): mousetweaks/2235 ... [continued]: open()) = -1 ENOENT No such file or directory
0.142 (0.018 ms): mousetweaks/2235 open(filename: 0x14c3c10, mode: 438 ) ...
0.142 ( ): probe:vfs_getname:(ffffffff812230bc) pathname="/home/acme/.icons/Adwaita/index.theme")
0.192 (0.069 ms): mousetweaks/2235 ... [continued]: open()) = -1 ENOENT No such file or directory
0.230 (0.017 ms): mousetweaks/2235 open(filename: 0x14c3c10, mode: 438 ) ...
0.230 ( ): probe:vfs_getname:(ffffffff812230bc) pathname="/usr/share/icons/Adwaita/cursors/xterm")
0.253 (0.041 ms): mousetweaks/2235 ... [continued]: open()) = 14
0.459 (0.008 ms): mousetweaks/2235 open(filename: 0x14e3910, mode: 438 ) ...
0.459 ( ): probe:vfs_getname:(ffffffff812230bc) pathname="/home/acme/.icons/Adwaita/cursors/left_side")
0.468 (0.017 ms): mousetweaks/2235 ... [continued]: open()) = -1 ENOENT No such file or directory
Need to combine that raw_syscalls:sys_enter(open) + probe:vfs_getname +
raw_syscalls:sys_exit(open) sequence...
Now, if you're bored, please write some more syscall groups, like the ones
in 'strace' and send it our way :-)
