perf tools: Add perf binary dependent rule for shellcheck log in Makefile.perf
Add rule in new Makefile "tests/Makefile.tests" for running shellcheck
on shell test scripts. This automates below shellcheck into the build.
$ for F in $(find tests/shell/ -perm -o=x -name '*.sh'); do shellcheck -S warning $F; done
Condition for shellcheck is added in Makefile.perf to avoid build
breakage in the absence of shellcheck binary. Update Makefile.perf to
contain new rule for "SHELLCHECK_TEST" which is for making shellcheck
test as a dependency on perf binary.
Added "tests/Makefile.tests" to run shellcheck on shellscripts in
tests/shell. The make rule "SHLLCHECK_RUN" ensures that, every time
during make, shellcheck will be run only on modified files during
subsequent invocations. By this, if any newly added shell scripts or
fixes in existing scripts breaks coding/formatting style, it will get
captured during the perf build.
Example build failure by modifying probe_vfs_getname.sh in tests/shell:
In tests/shell/probe_vfs_getname.sh line 8:
. $(dirname $0)/lib/probe.sh
^-----------^ SC2046 (warning): Quote this to prevent word splitting.
For more information:

Here, like other files which gets created during compilation (ex:
.builtin-bench.o.cmd or .perf.o.cmd ), create .shellcheck_log also as a
hidden file. Example: tests/shell/.probe_vfs_getname.sh.shellcheck_log
shellcheck is re-run if any of the script gets modified based on its
dependency of this log file.
After this, for testing, changed "tests/shell/trace+probe_vfs_getname.sh" to
break shellcheck format. In the next make run, it is also captured:
In tests/shell/probe_vfs_getname.sh line 8:

make[2]: *** Waiting for unfinished jobs....
make[1]: *** [Makefile.perf:244: sub-make] Error 2
make: *** [Makefile:70: all] Error 2
Failure log can be found in the stdout of make itself.
This is reported at build time. To be able to go ahead with the build or
disable shellcheck even though it is known that some test is broken, add
a "NO_SHELLCHECK" option. Example:
make NO_SHELLCHECK=1
INSTALL libsubcmd_headers
INSTALL libsymbol_headers
INSTALL libapi_headers
INSTALL libperf_headers
INSTALL libbpf_headers
LINK perf
Note:
This is tested on RHEL and also SLES. Use below check:
"$(shell which shellcheck 2> /dev/null)" to look for presence
of shellcheck binary. The approach "shell command -v" is not
used here. In some of the distros(RHEL), command is available
as executable file (/usr/bin/command). But in some distros(SLES),
it is a shell builtin and not available as executable file.
Committer testing:
$ type shellcheck
shellcheck is hashed (/usr/bin/shellcheck)
$ rpm -qf /usr/bin/shellcheck
ShellCheck-0.9.0-2.fc38.x86_64

perf tools: Build syscall table .c header from kernel's syscall_64.tbl
We used libaudit to map ids to syscall names and vice-versa, but that
imposes a delay in supporting new syscalls, having to wait for libaudit
to get those new syscalls on its tables.
To remove that delay, for x86_64 initially, grab a copy of
arch/x86/entry/syscalls/syscall_64.tbl and use it to generate those
tables.
Syscalls currently not available in audit-libs:
# trace -e copy_file_range,membarrier,mlock2,pread64,pwrite64,timerfd_create,userfaultfd
Error: Invalid syscall copy_file_range, membarrier, mlock2, pread64, pwrite64, timerfd_create, userfaultfd
Hint: try 'perf list syscalls:sys_enter_*'
Hint: and: 'man syscalls'
#
With this patch:
# trace -e copy_file_range,membarrier,mlock2,pread64,pwrite64,timerfd_create,userfaultfd

To remove that delay, for x86_64 initially, grab a copy of
arch/x86/entry/syscalls/syscall_64.tbl and use it to generate those
tables.
Syscalls currently not available in audit-libs:
# trace -e copy_file_range,membarrier,mlock2,pread64,pwrite64,timerfd_create,userfaultfd
Error: Invalid syscall copy_file_range, membarrier, mlock2, pread64, pwrite64, timerfd_create, userfaultfd
Hint: try 'perf list syscalls:sys_enter_*'
Hint: and: 'man syscalls'
#
With this patch:
# trace -e copy_file_range,membarrier,mlock2,pread64,pwrite64,timerfd_create,userfaultfd

perf tools: Add Python 3 support
Added Python 3 support while keeping Python 2.7 compatibility.
Committer notes:
This doesn't make it to auto detect python 3, one has to explicitely ask
it to build with python 3 devel files, here are the instructions
provided by Jaroslav:
---
$ cp -a tools/perf tools/python3-perf
$ make V=1 prefix=/usr -C tools/perf PYTHON=/usr/bin/python2 all
$ make V=1 prefix=/usr -C tools/python3-perf PYTHON=/usr/bin/python3 all
$ make V=1 prefix=/usr -C tools/python3-perf PYTHON=/usr/bin/python3 DESTDIR=%{buildroot} install-python_ext
$ make V=1 prefix=/usr -C tools/perf PYTHON=/usr/bin/python2 DESTDIR=%{buildroot} install-python_ext
---
We need to make this automatic, just like the existing tests for checking if
the python2 devel files are in place, allowing the build with python3 if
available, fallbacking to python2 and then just disabling it if none are
available.
So, using the PYTHON variable to build it using O= we get:
Before this patch:
$ rpm -q python3 python3-devel
python3-3.6.4-7.fc27.x86_64
python3-devel-3.6.4-7.fc27.x86_64
$ rm -rf /tmp/build/perf/ ; mkdir -p /tmp/build/perf ; make O=/tmp/build/perf PYTHON=/usr/bin/python3 -C tools/perf install-bin
make: Entering directory '/home/acme/git/linux/tools/perf'
<SNIP>
Makefile.config:670: Python 3 is not yet supported; please set
Makefile.config:671: PYTHON and/or PYTHON_CONFIG appropriately.
Makefile.config:672: If you also have Python 2 installed, then
Makefile.config:673: try something like:
Makefile.config:674:
Makefile.config:675: make PYTHON=python2
Makefile.config:676:
Makefile.config:677: Otherwise, disable Python support entirely:
Makefile.config:678:
Makefile.config:679: make NO_LIBPYTHON=1
Makefile.config:680:
Makefile.config:681: *** . Stop.
make[1]: *** [Makefile.perf:212: sub-make] Error 2
make: *** [Makefile:110: install-bin] Error 2
make: Leaving directory '/home/acme/git/linux/tools/perf'
$
After:
$ make O=/tmp/build/perf PYTHON=python3 -C tools/perf install-bin
$ ldd ~/bin/perf | grep python
libpython3.6m.so.1.0 => /lib64/libpython3.6m.so.1.0 (0x00007f58a31e8000)
$ rpm -qf /lib64/libpython3.6m.so.1.0
python3-libs-3.6.4-7.fc27.x86_64
$
Now verify that when using the binding the right ELF file is loaded,
using perf trace:
$ perf trace -e open* perf test python
0.051 ( 0.016 ms): perf/3927 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC ) = 3
<SNIP>
18: 'import perf' in python :
8.849 ( 0.013 ms): sh/3929 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC ) = 3
<SNIP>
25.572 ( 0.008 ms): python3/3931 openat(dfd: CWD, filename: /tmp/build/perf/python/perf.cpython-36m-x86_64-linux-gnu.so, flags: CLOEXEC) = 3
<SNIP>
Ok
<SNIP>
$
And using tools/perf/python/twatch.py, to show PERF_RECORD_ metaevents:
$ python3 tools/perf/python/twatch.py

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.
Committer testing:
$ rpm -qi libtraceevent-devel

#
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 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.

perf beauty: Hook up the x86 MSR table generator
This way we generate the source with the table for later use by plugins,
etc.
I.e. after running:
$ make -C tools/perf O=/tmp/build/perf
We end up with:
$ head /tmp/build/perf/trace/beauty/generated/x86_arch_MSRs_array.c
static const char *x86_MSRs[] = {
[0x00000000] = "IA32_P5_MC_ADDR",
[0x00000001] = "IA32_P5_MC_TYPE",
[0x00000010] = "IA32_TSC",
[0x00000017] = "IA32_PLATFORM_ID",
[0x0000001b] = "IA32_APICBASE",
[0x00000020] = "KNC_PERFCTR0",
[0x00000021] = "KNC_PERFCTR1",
[0x00000028] = "KNC_EVNTSEL0",
[0x00000029] = "KNC_EVNTSEL1",
$
Now its just a matter of using it, first in a libtracevent plugin.
At some point we should move tools/perf/trace/beauty to tools/beauty/,
so that it can be used more generally and even made available externally
like libbpf, libperf, libtraevent, etc.

perf trace beauty: Beautify pkey_{alloc,free,mprotect} arguments
Reuse 'mprotect' beautifiers for 'pkey_mprotect'.
System wide tracing pkey_alloc, pkey_free and pkey_mprotect calls, with
backtraces:
# perf trace -e pkey_alloc,pkey_mprotect,pkey_free --max-stack=5
0.000 ( 0.011 ms): pkey/7818 pkey_alloc(init_val: DISABLE_ACCESS|DISABLE_WRITE) = -1 EINVAL Invalid argument
syscall (/usr/lib64/libc-2.25.so)
pkey_alloc (/home/acme/c/pkey)
0.022 ( 0.003 ms): pkey/7818 pkey_mprotect(start: 0x7f28c3890000, len: 4096, prot: READ|WRITE, pkey: -1) = 0
syscall (/usr/lib64/libc-2.25.so)
pkey_mprotect (/home/acme/c/pkey)
0.030 ( 0.002 ms): pkey/7818 pkey_free(pkey: -1 ) = -1 EINVAL Invalid argument
syscall (/usr/lib64/libc-2.25.so)
pkey_free (/home/acme/c/pkey)
The tools/include/uapi/asm-generic/mman-common.h file is used to find
the access rights defines for the pkey_alloc syscall second argument.
Since we have the detector of changes for the tools/include header files
versus its kernel origin (include/uapi/asm-generic/mman-common.h), we'll
get whatever new flag appears for that argument automatically.
This method should be used in other cases where it is easy to generate
those flags tables because the header has properly namespaced defines
like PKEY_DISABLE_ACCESS and PKEY_DISABLE_WRITE.

perf trace beautify ioctl: Beautify sound ioctl's 'cmd' arg
This time we try a new approach, using a copy of uapi/sound/asound.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.
This way either the sound developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
E.g.:
# perf trace -p 22084 -e ioctl 2>&1 | head -5
0.000 ( 0.068 ms): alsa-sink-ALC3/22084 ioctl(fd: 49</dev/snd/pcmC1D0p>, cmd: SNDRV_PCM_HWSYNC, arg: 0x557f8d7fa0f0) = 0

perf trace: Beautify 'fspick' arguments
Use existing beautifiers for the first 2 args (dfd, path) and wire up
the recently introduced fspick flags table generator.
Now it should be possible to just use:
perf trace -e fspick
As root and see all move_mount syscalls with its args beautified, either
using the vfs_getname perf probe method or using the
augmented_raw_syscalls.c eBPF helper to get the pathnames, the other
args should work in all cases, i.e. all that is needed can be obtained
directly from the raw_syscalls:sys_enter tracepoint args.

perf trace: Beautify 'fsconfig' arguments
Use existing beautifiers for the first arg, fd, assigned using the
heuristic that looks for syscall arg names and associates SCA_FD with
'fd' named argumes, and wire up the recently introduced fsconfig cmd
table generator.
Now it should be possible to just use:
perf trace -e fsconfig
As root and see all fsconfig syscalls with its args beautified, more
work needed to look at the command and according to it handle the 'key',
'value' and 'aux' args, using the 'fcntl' and 'futex' beautifiers as a
starting point to see how to suppress sets of these last three args that
may not be used by the 'cmd' arg, etc.

perf trace beauty: Beautify pkey_{alloc,free,mprotect} arguments
Reuse 'mprotect' beautifiers for 'pkey_mprotect'.
System wide tracing pkey_alloc, pkey_free and pkey_mprotect calls, with
backtraces:
# perf trace -e pkey_alloc,pkey_mprotect,pkey_free --max-stack=5
0.000 ( 0.011 ms): pkey/7818 pkey_alloc(init_val: DISABLE_ACCESS|DISABLE_WRITE) = -1 EINVAL Invalid argument
syscall (/usr/lib64/libc-2.25.so)
pkey_alloc (/home/acme/c/pkey)
0.022 ( 0.003 ms): pkey/7818 pkey_mprotect(start: 0x7f28c3890000, len: 4096, prot: READ|WRITE, pkey: -1) = 0
syscall (/usr/lib64/libc-2.25.so)
pkey_mprotect (/home/acme/c/pkey)
0.030 ( 0.002 ms): pkey/7818 pkey_free(pkey: -1 ) = -1 EINVAL Invalid argument
syscall (/usr/lib64/libc-2.25.so)
pkey_free (/home/acme/c/pkey)
The tools/include/uapi/asm-generic/mman-common.h file is used to find
the access rights defines for the pkey_alloc syscall second argument.
Since we have the detector of changes for the tools/include header files
versus its kernel origin (include/uapi/asm-generic/mman-common.h), we'll
get whatever new flag appears for that argument automatically.
This method should be used in other cases where it is easy to generate
those flags tables because the header has properly namespaced defines
like PKEY_DISABLE_ACCESS and PKEY_DISABLE_WRITE.

perf trace beautify ioctl: Beautify sound ioctl's 'cmd' arg
This time we try a new approach, using a copy of uapi/sound/asound.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.
This way either the sound developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
E.g.:
# perf trace -p 22084 -e ioctl 2>&1 | head -5
0.000 ( 0.068 ms): alsa-sink-ALC3/22084 ioctl(fd: 49</dev/snd/pcmC1D0p>, cmd: SNDRV_PCM_HWSYNC, arg: 0x557f8d7fa0f0) = 0

This time we try a new approach, using a copy of uapi/sound/asound.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.
This way either the sound developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
E.g.:
# perf trace -p 22084 -e ioctl 2>&1 | head -5
0.000 ( 0.068 ms): alsa-sink-ALC3/22084 ioctl(fd: 49</dev/snd/pcmC1D0p>, cmd: SNDRV_PCM_HWSYNC, arg: 0x557f8d7fa0f0) = 0

perf trace beauty kcmp: Beautify arguments
For some unknown reason there is no entry in tracefs's syscalls for
kcmp, i.e. no tracefs/events/syscalls/sys_{enter,exit}_kcmp, so we need
to provide a data dictionary for the fields.
To beautify the 'type' argument we automatically generate a strarray
from tools/include/uapi/kcmp.h, the idx1 and idx2 args, nowadays used
only if type == KCMP_FILE, are masked for all the other types and a
lookup is made for the thread and fd to show the path, if possible,
getting it from the probe:vfs_getname if in place or from procfs, races
allowing.
A system wide strace like tracing session, with callchains shows just
one user so far in this fedora 25 machine:
# perf trace --max-stack 5 -e kcmp
<SNIP>
1502914.400 ( 0.001 ms): systemd/1 kcmp(pid1: 1 (systemd), pid2: 1 (systemd), type: FILE, idx1: 271<socket:[4723475]>, idx2: 25<socket:[4788686]>) = -1 ENOSYS Function not implemented
syscall (/usr/lib64/libc-2.25.so)
same_fd (/usr/lib/systemd/libsystemd-shared-233.so)
service_add_fd_store (/usr/lib/systemd/systemd)
service_notify_message.lto_priv.127 (/usr/lib/systemd/systemd)
1502914.407 ( 0.001 ms): systemd/1 kcmp(pid1: 1 (systemd), pid2: 1 (systemd), type: FILE, idx1: 270<socket:[4726396]>, idx2: 25<socket:[4788686]>) = -1 ENOSYS Function not implemented
syscall (/usr/lib64/libc-2.25.so)
same_fd (/usr/lib/systemd/libsystemd-shared-233.so)
service_add_fd_store (/usr/lib/systemd/systemd)
service_notify_message.lto_priv.127 (/usr/lib/systemd/systemd)
<SNIP>
The backtraces seem to agree this is really kcmp(), but this system
doesn't have the sys_kcmp(), bummer:
# uname -a
Linux jouet 4.14.0-rc3+ #1 SMP Fri Oct 13 12:21:12 -03 2017 x86_64 x86_64 x86_64 GNU/Linux
# grep kcmp /proc/kallsyms
ffffffffb60b8890 W sys_kcmp
$ grep CONFIG_CHECKPOINT_RESTORE ../build/v4.14.0-rc3+/.config
# CONFIG_CHECKPOINT_RESTORE is not set
$
So systemd uses it, good fedora kernel config has it:
$ grep CONFIG_CHECKPOINT_RESTORE /boot/config-4.13.4-200.fc26.x86_64
CONFIG_CHECKPOINT_RESTORE=y

perf trace beautify ioctl: Beautify KVM ioctl's 'cmd' arg
Also trying a new approach, using a copy of uapi/linux/kvm.h we auto
generate the string tables, then include it in the ioctl cmd beautifier.
This way either the KVM developers will add the new commands to the

comes to mind), or we'll be notified when building perf that our copy

E.g., a tracing a process and its threads, but would work for system wide as
well, just drop that '-p 21238', to see ioctls for DRM, tty, sound, etc:

be valid, but use the same number as others, those were removed in the
shell script that builds the table, tools/perf/trace/beauty/kvm_ioctl.sh.
Since so far we're supporting only x86 in the 'cmd' ioctl arg beautifier
in perf trace, we can leave fully supporting these ioctls for later.
There are some more to handle here, notably the one for /dev/vhost-net, will
come later.

perf trace beautify ioctl: Beautify vhost virtio ioctl's 'cmd' arg
Also trying a new approach, using a copy of uapi/linux/vhost.h we auto
generate the string tables, then include it in the ioctl cmd beautifier.
This way either the KVM developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
E.g., doing syswide tracing grepping for the newly beautified VHOST
ioctls:

^C
'-e ioctl' uses tracepoint filters, in time this will be replaces by
eBPF filters hooked at the syscall tracepoints and that "grep VHOST"
will also be done with eBPF, right at the kernel, to reduce overhead.

And to have the system's sys/mman.h find the definition of MAP_SHARED
and MAP_PRIVATE, make sure they are defined in the tools/ mman-common.h
in a way that keeps it the same as the kernel's, need for keeping the
Android's NDK cross build working.
This silences these perf build warnings:

perf trace: Beautify 'move_mount' arguments
Use existing beautifiers for the first 4 args (to/from fds, pathnames)
and wire up the recently introduced move_mount flags table generator.
Now it should be possible to just use:
perf trace -e move_mount
As root and see all move_mount syscalls with its args beautified, except
for the filenames, that need work in the augmented_raw_syscalls.c eBPF
helper to pass more than one, see comment in the
augmented_raw_syscalls.c source code, the other args should work in all
cases, i.e. all that is needed can be obtained directly from the
raw_syscalls:sys_enter tracepoint args.
Running without the strace "skin" (.perfconfig setting output formatting
switches to look like strace output + BPF to collect strings, as we
still need to support collecting multiple string args for the same
syscall, like with move_mount):
# cat sys_move_mount.c
#define _GNU_SOURCE /* See feature_test_macros(7) */
#include <unistd.h>
#include <sys/syscall.h> /* For SYS_xxx definitions */
#define __NR_move_mount 429
#define MOVE_MOUNT_F_SYMLINKS 0x00000001 /* Follow symlinks on from path */
#define MOVE_MOUNT_F_AUTOMOUNTS 0x00000002 /* Follow automounts on from path */
#define MOVE_MOUNT_F_EMPTY_PATH 0x00000004 /* Empty from path permitted */
#define MOVE_MOUNT_T_SYMLINKS 0x00000010 /* Follow symlinks on to path */

perf trace beauty prctl: Generate 'option' string table from kernel headers
This is one more case where the way that syscall parameter values are
defined in kernel headers are easy to parse using a shell script that
will then generate the string table that gets used by the prctl 'option'
argument beautifier.
This way as soon as the header syncronization mechanism in perf's build
system detects a change in a copy of a kernel ABI header and that file

perf trace beauty prctl: Generate 'option' string table from kernel headers
This is one more case where the way that syscall parameter values are
defined in kernel headers are easy to parse using a shell script that
will then generate the string table that gets used by the prctl 'option'
argument beautifier.
This way as soon as the header syncronization mechanism in perf's build
system detects a change in a copy of a kernel ABI header and that file
is syncronized, we get 'perf trace' updated automagically.
Further work needed for the PR_SET_ values, as well for using eBPF to
copy the non-integer arguments to/from the kernel.
E.g.: System wide prctl tracing:
# perf trace -e prctl

At some point we should move tools/perf/trace/beauty to tools/beauty/,
so that it can be used more generally and even made available externally
like libbpf, libperf, libtraceevent, etc.

perf beauty: Hook up the x86 MSR table generator
This way we generate the source with the table for later use by plugins,

I.e. after running:

[0x00000028] = "KNC_EVNTSEL0",
[0x00000029] = "KNC_EVNTSEL1",
$
Now its just a matter of using it, first in a libtracevent plugin.
At some point we should move tools/perf/trace/beauty to tools/beauty/,

perf trace: Beautify 'sync_file_range' arguments
Use existing beautifiers for the first arg, fd, assigned using the
heuristic that looks for syscall arg names and associates SCA_FD with
'fd' named argumes, and wire up the recently introduced sync_file_range
flags table generator.
Now it should be possible to just use:
perf trace -e sync_file_range
As root and see all sync_file_range syscalls with its args beautified.
Doing a syscall strace like session looking for this syscall, then run
postgresql's initdb command:
# perf trace -e sync_file_range
<SNIP>
initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0
initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0

perf trace: Beautify 'sync_file_range' arguments
Use existing beautifiers for the first arg, fd, assigned using the
heuristic that looks for syscall arg names and associates SCA_FD with
'fd' named argumes, and wire up the recently introduced sync_file_range
flags table generator.
Now it should be possible to just use:
perf trace -e sync_file_range
As root and see all sync_file_range syscalls with its args beautified.
Doing a syscall strace like session looking for this syscall, then run
postgresql's initdb command:
# perf trace -e sync_file_range

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 tools: Add Python 3 support
Added Python 3 support while keeping Python 2.7 compatibility.
Committer notes:
This doesn't make it to auto detect python 3, one has to explicitely ask
it to build with python 3 devel files, here are the instructions
provided by Jaroslav:
---
$ cp -a tools/perf tools/python3-perf
$ make V=1 prefix=/usr -C tools/perf PYTHON=/usr/bin/python2 all
$ make V=1 prefix=/usr -C tools/python3-perf PYTHON=/usr/bin/python3 all
$ make V=1 prefix=/usr -C tools/python3-perf PYTHON=/usr/bin/python3 DESTDIR=%{buildroot} install-python_ext
$ make V=1 prefix=/usr -C tools/perf PYTHON=/usr/bin/python2 DESTDIR=%{buildroot} install-python_ext
---
We need to make this automatic, just like the existing tests for checking if
the python2 devel files are in place, allowing the build with python3 if
available, fallbacking to python2 and then just disabling it if none are
available.
So, using the PYTHON variable to build it using O= we get:
Before this patch:
$ rpm -q python3 python3-devel
python3-3.6.4-7.fc27.x86_64
python3-devel-3.6.4-7.fc27.x86_64
$ rm -rf /tmp/build/perf/ ; mkdir -p /tmp/build/perf ; make O=/tmp/build/perf PYTHON=/usr/bin/python3 -C tools/perf install-bin
make: Entering directory '/home/acme/git/linux/tools/perf'
<SNIP>
Makefile.config:670: Python 3 is not yet supported; please set
Makefile.config:671: PYTHON and/or PYTHON_CONFIG appropriately.
Makefile.config:672: If you also have Python 2 installed, then
Makefile.config:673: try something like:
Makefile.config:674:
Makefile.config:675: make PYTHON=python2
Makefile.config:676:
Makefile.config:677: Otherwise, disable Python support entirely:
Makefile.config:678:
Makefile.config:679: make NO_LIBPYTHON=1
Makefile.config:680:
Makefile.config:681: *** . Stop.
make[1]: *** [Makefile.perf:212: sub-make] Error 2
make: *** [Makefile:110: install-bin] Error 2
make: Leaving directory '/home/acme/git/linux/tools/perf'
$
After:
$ make O=/tmp/build/perf PYTHON=python3 -C tools/perf install-bin
$ ldd ~/bin/perf | grep python
libpython3.6m.so.1.0 => /lib64/libpython3.6m.so.1.0 (0x00007f58a31e8000)
$ rpm -qf /lib64/libpython3.6m.so.1.0
python3-libs-3.6.4-7.fc27.x86_64
$
Now verify that when using the binding the right ELF file is loaded,
using perf trace:
$ perf trace -e open* perf test python
0.051 ( 0.016 ms): perf/3927 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC ) = 3
<SNIP>
18: 'import perf' in python :
8.849 ( 0.013 ms): sh/3929 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC ) = 3
<SNIP>
25.572 ( 0.008 ms): python3/3931 openat(dfd: CWD, filename: /tmp/build/perf/python/perf.cpython-36m-x86_64-linux-gnu.so, flags: CLOEXEC) = 3
<SNIP>
Ok
<SNIP>
$
And using tools/perf/python/twatch.py, to show PERF_RECORD_ metaevents:
$ python3 tools/perf/python/twatch.py

PYTHON=python3 part, which will make it use python2 if its devel files are
available, like in this test:

perf jevents: Program to convert JSON file
This is a modified version of an earlier patch by Andi Kleen.
We expect architectures to create JSON files describing the performance
monitoring (PMU) events that each CPU model/family of the architecture
supports.
Following is an example of the JSON file entry for an x86 event:
[
...
{
"EventCode": "0x00",
"UMask": "0x01",
"EventName": "INST_RETIRED.ANY",
"BriefDescription": "Instructions retired from execution.",
"PublicDescription": "Instructions retired from execution.",
"Counter": "Fixed counter 1",
"CounterHTOff": "Fixed counter 1",
"SampleAfterValue": "2000003",
"SampleAfterValue": "2000003",
"MSRIndex": "0",
"MSRValue": "0",
"TakenAlone": "0",
"CounterMask": "0",
"Invert": "0",
"AnyThread": "0",
"EdgeDetect": "0",
"PEBS": "0",
"PRECISE_STORE": "0",
"Errata": "null",
"Offcore": "0"
},
...
]
All the PMU events supported by a CPU model/family must be grouped into
"topics" such as "Pipelining", "Floating-point", "Virtual-memory" etc.
All events belonging to a topic must be placed in a separate JSON file
(eg: "Pipelining.json") and all the topic JSON files for a CPU model must
be in a separate directory.
Eg: for the CPU model "Silvermont_core":
$ ls tools/perf/pmu-events/arch/x86/Silvermont_core
Floating-point.json
Memory.json
Other.json
Pipelining.json
Virtualmemory.json
Finally, to allow multiple CPU models to share a single set of JSON files,
architectures must provide a mapping between a model and its set of events:
$ grep Silvermont tools/perf/pmu-events/arch/x86/mapfile.csv
GenuineIntel-6-4D,V13,Silvermont_core,core
GenuineIntel-6-4C,V13,Silvermont_core,core
which maps each CPU, identified by [vendor, family, model, version, type]
to a directory of JSON files. Thus two (or more) CPU models support the
set of PMU events listed in the directory.
tools/perf/pmu-events/arch/x86/Silvermont_core/
Given this organization of files, the program, jevents:
- locates all JSON files for each CPU-model of the architecture,
- parses all JSON files for the CPU-model and generates a C-style
"PMU-events table" (pmu-events.c) for the model
- locates a mapfile for the architecture
- builds a global table, mapping each model of CPU to the corresponding
PMU-events table.
The 'pmu-events.c' is generated when building perf and added to libperf.a.
The global table pmu_events_map[] table in this pmu-events.c will be used
in perf in a follow-on patch.
If the architecture does not have any JSON files or there is an error in
processing them, an empty mapping file is created. This would allow the
build of perf to proceed even if we are not able to provide aliases for
events.
The parser for JSON files allows parsing Intel style JSON event files. This
allows to use an Intel event list directly with perf. The Intel event lists
can be quite large and are too big to store in unswappable kernel memory.
The conversion from JSON to C-style is straight forward. The parser knows
(very little) Intel specific information, and can be easily extended to
handle fields for other CPUs.
The parser code is partially shared with an independent parsing library,
which is 2-clause BSD licensed. To avoid any conflicts I marked those
files as BSD licensed too. As part of perf they become GPLv2.
Committer notes:
Fixes:
1) Limit maxfds to 512 to avoid nftd() segfaulting on alloca() with a
big rlim_max, as in docker containers - acme
2) Make jevents a hostprog, supporting cross compilation - jolsa
3) Use HOSTCC for jevents final step - acme
4) Define _GNU_SOURCE for asprintf, as we can't use CC's EXTRA_CFLAGS,
that has to have --sysroot on the Android NDK 24 - acme
5) Removed $(srctree)/tools/perf/pmu-events/pmu-events.c from the
'clean' target, it is generated on $(OUTPUT)pmu-events/pmu-events.c,
which is already taken care of in the original patch - acme

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.

- 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 tools: Stop depending on .git files for building PERF-VERSION-FILE
This essentially reverts commit c72e3f04b45fb2e5 ("tools/perf/build:
Speed up git-version test on re-make") and commit 4e666cdb06eede20
("perf tools: Fix dependency for version file creation")
In commit c72e3f04b45fb2e5 ("tools/perf/build: Speed up git-version test
on re-make"), a makefile dependency on .git/HEAD was added. The
background is that running PERF-VERSION-FILE is relatively slow, and
commands like "git describe" are particularly slow.
In commit 4e666cdb06eede20 ("perf tools: Fix dependency for version file
creation"), an additional dependency on .git/ORIG_HEAD was added, as
.git/HEAD may not change for "git reset --hard HEAD^" command. However,
depending on whether we're on a branch or not, a "git cherry-pick" may
not lead to the version being updated.
As discussed with the git community in [0], using git internal files for
dependencies is not reliable. Commit 4e666cdb06ee also breaks some build
scenarios [1].
As mentioned, c72e3f04b45fb2e5 ("tools/perf/build: Speed up git-version
test on re-make") was added to speed up the build. However in commit
7572733b84997d23 ("perf tools: Fix version kernel tag") we removed the
call to "git describe", so just revert Makefile.perf back to same as pre
c72e3f04b45fb2e5 ("tools/perf/build: Speed up git-version test on
re-make") and the build should not be so slow, as below:
Pre 7572733b8499:

perf jevents: Program to convert JSON file
This is a modified version of an earlier patch by Andi Kleen.
We expect architectures to create JSON files describing the performance
monitoring (PMU) events that each CPU model/family of the architecture
supports.
Following is an example of the JSON file entry for an x86 event:
[
...
{
"EventCode": "0x00",
"UMask": "0x01",
"EventName": "INST_RETIRED.ANY",
"BriefDescription": "Instructions retired from execution.",
"PublicDescription": "Instructions retired from execution.",
"Counter": "Fixed counter 1",
"CounterHTOff": "Fixed counter 1",
"SampleAfterValue": "2000003",
"SampleAfterValue": "2000003",
"MSRIndex": "0",
"MSRValue": "0",
"TakenAlone": "0",
"CounterMask": "0",
"Invert": "0",
"AnyThread": "0",
"EdgeDetect": "0",
"PEBS": "0",
"PRECISE_STORE": "0",
"Errata": "null",
"Offcore": "0"
},
...
]
All the PMU events supported by a CPU model/family must be grouped into
"topics" such as "Pipelining", "Floating-point", "Virtual-memory" etc.
All events belonging to a topic must be placed in a separate JSON file
(eg: "Pipelining.json") and all the topic JSON files for a CPU model must
be in a separate directory.
Eg: for the CPU model "Silvermont_core":
$ ls tools/perf/pmu-events/arch/x86/Silvermont_core
Floating-point.json
Memory.json
Other.json
Pipelining.json
Virtualmemory.json
Finally, to allow multiple CPU models to share a single set of JSON files,
architectures must provide a mapping between a model and its set of events:
$ grep Silvermont tools/perf/pmu-events/arch/x86/mapfile.csv
GenuineIntel-6-4D,V13,Silvermont_core,core
GenuineIntel-6-4C,V13,Silvermont_core,core
which maps each CPU, identified by [vendor, family, model, version, type]
to a directory of JSON files. Thus two (or more) CPU models support the
set of PMU events listed in the directory.
tools/perf/pmu-events/arch/x86/Silvermont_core/
Given this organization of files, the program, jevents:
- locates all JSON files for each CPU-model of the architecture,
- parses all JSON files for the CPU-model and generates a C-style
"PMU-events table" (pmu-events.c) for the model
- locates a mapfile for the architecture
- builds a global table, mapping each model of CPU to the corresponding
PMU-events table.
The 'pmu-events.c' is generated when building perf and added to libperf.a.
The global table pmu_events_map[] table in this pmu-events.c will be used
in perf in a follow-on patch.
If the architecture does not have any JSON files or there is an error in
processing them, an empty mapping file is created. This would allow the
build of perf to proceed even if we are not able to provide aliases for
events.
The parser for JSON files allows parsing Intel style JSON event files. This
allows to use an Intel event list directly with perf. The Intel event lists
can be quite large and are too big to store in unswappable kernel memory.
The conversion from JSON to C-style is straight forward. The parser knows
(very little) Intel specific information, and can be easily extended to
handle fields for other CPUs.
The parser code is partially shared with an independent parsing library,
which is 2-clause BSD licensed. To avoid any conflicts I marked those
files as BSD licensed too. As part of perf they become GPLv2.
Committer notes:
Fixes:
1) Limit maxfds to 512 to avoid nftd() segfaulting on alloca() with a
big rlim_max, as in docker containers - acme
2) Make jevents a hostprog, supporting cross compilation - jolsa
3) Use HOSTCC for jevents final step - acme
4) Define _GNU_SOURCE for asprintf, as we can't use CC's EXTRA_CFLAGS,
that has to have --sysroot on the Android NDK 24 - acme
5) Removed $(srctree)/tools/perf/pmu-events/pmu-events.c from the
'clean' target, it is generated on $(OUTPUT)pmu-events/pmu-events.c,
which is already taken care of in the original patch - acme

kbuild: replace $(if A,A,B) with $(or A,B)
$(or ...) is available since GNU Make 3.81, and useful to shorten the
code in some places.
Covert as follows:
$(if A,A,B) --> $(or A,B)
This patch also converts:
$(if A, A, B) --> $(or A, B)
Strictly speaking, the latter is not an equivalent conversion because
GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B)
expands to " A", while $(or A, B) expands to "A".
Anyway, preceding spaces are not significant in the code hunks I touched.

perf trace: Beautify 'fsconfig' arguments
Use existing beautifiers for the first arg, fd, assigned using the
heuristic that looks for syscall arg names and associates SCA_FD with
'fd' named argumes, and wire up the recently introduced fsconfig cmd
table generator.
Now it should be possible to just use:
perf trace -e fsconfig
As root and see all fsconfig syscalls with its args beautified, more
work needed to look at the command and according to it handle the 'key',
'value' and 'aux' args, using the 'fcntl' and 'futex' beautifiers as a
starting point to see how to suppress sets of these last three args that
may not be used by the 'cmd' arg, etc.

perf trace: Beautify 'fspick' arguments
Use existing beautifiers for the first 2 args (dfd, path) and wire up
the recently introduced fspick flags table generator.
Now it should be possible to just use:
perf trace -e fspick
As root and see all move_mount syscalls with its args beautified, either
using the vfs_getname perf probe method or using the
augmented_raw_syscalls.c eBPF helper to get the pathnames, the other
args should work in all cases, i.e. all that is needed can be obtained
directly from the raw_syscalls:sys_enter tracepoint args.

perf trace beauty: Beautify pkey_{alloc,free,mprotect} arguments
Reuse 'mprotect' beautifiers for 'pkey_mprotect'.
System wide tracing pkey_alloc, pkey_free and pkey_mprotect calls, with
backtraces:
# perf trace -e pkey_alloc,pkey_mprotect,pkey_free --max-stack=5
0.000 ( 0.011 ms): pkey/7818 pkey_alloc(init_val: DISABLE_ACCESS|DISABLE_WRITE) = -1 EINVAL Invalid argument
syscall (/usr/lib64/libc-2.25.so)
pkey_alloc (/home/acme/c/pkey)
0.022 ( 0.003 ms): pkey/7818 pkey_mprotect(start: 0x7f28c3890000, len: 4096, prot: READ|WRITE, pkey: -1) = 0
syscall (/usr/lib64/libc-2.25.so)
pkey_mprotect (/home/acme/c/pkey)
0.030 ( 0.002 ms): pkey/7818 pkey_free(pkey: -1 ) = -1 EINVAL Invalid argument
syscall (/usr/lib64/libc-2.25.so)
pkey_free (/home/acme/c/pkey)
The tools/include/uapi/asm-generic/mman-common.h file is used to find
the access rights defines for the pkey_alloc syscall second argument.
Since we have the detector of changes for the tools/include header files
versus its kernel origin (include/uapi/asm-generic/mman-common.h), we'll
get whatever new flag appears for that argument automatically.
This method should be used in other cases where it is easy to generate
those flags tables because the header has properly namespaced defines
like PKEY_DISABLE_ACCESS and PKEY_DISABLE_WRITE.

perf trace beautify ioctl: Beautify KVM ioctl's 'cmd' arg
Also trying a new approach, using a copy of uapi/linux/kvm.h we auto
generate the string tables, then include it in the ioctl cmd beautifier.
This way either the KVM developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
E.g., a tracing a process and its threads, but would work for system wide as
well, just drop that '-p 21238', to see ioctls for DRM, tty, sound, etc:

Since there are clashes in _IOC_NR() for some cases, notably ioctls with
PPC_ and ARM_ in its name and some that depend on some internal state to
be valid, but use the same number as others, those were removed in the
shell script that builds the table, tools/perf/trace/beauty/kvm_ioctl.sh.
Since so far we're supporting only x86 in the 'cmd' ioctl arg beautifier
in perf trace, we can leave fully supporting these ioctls for later.
There are some more to handle here, notably the one for /dev/vhost-net, will
come later.

perf trace beauty kcmp: Beautify arguments
For some unknown reason there is no entry in tracefs's syscalls for
kcmp, i.e. no tracefs/events/syscalls/sys_{enter,exit}_kcmp, so we need
to provide a data dictionary for the fields.
To beautify the 'type' argument we automatically generate a strarray
from tools/include/uapi/kcmp.h, the idx1 and idx2 args, nowadays used
only if type == KCMP_FILE, are masked for all the other types and a
lookup is made for the thread and fd to show the path, if possible,
getting it from the probe:vfs_getname if in place or from procfs, races
allowing.
A system wide strace like tracing session, with callchains shows just
one user so far in this fedora 25 machine:
# perf trace --max-stack 5 -e kcmp
<SNIP>
1502914.400 ( 0.001 ms): systemd/1 kcmp(pid1: 1 (systemd), pid2: 1 (systemd), type: FILE, idx1: 271<socket:[4723475]>, idx2: 25<socket:[4788686]>) = -1 ENOSYS Function not implemented
syscall (/usr/lib64/libc-2.25.so)
same_fd (/usr/lib/systemd/libsystemd-shared-233.so)

service_notify_message.lto_priv.127 (/usr/lib/systemd/systemd)
1502914.407 ( 0.001 ms): systemd/1 kcmp(pid1: 1 (systemd), pid2: 1 (systemd), type: FILE, idx1: 270<socket:[4726396]>, idx2: 25<socket:[4788686]>) = -1 ENOSYS Function not implemented

service_add_fd_store (/usr/lib/systemd/systemd)
service_notify_message.lto_priv.127 (/usr/lib/systemd/systemd)
<SNIP>
The backtraces seem to agree this is really kcmp(), but this system
doesn't have the sys_kcmp(), bummer:
# uname -a
Linux jouet 4.14.0-rc3+ #1 SMP Fri Oct 13 12:21:12 -03 2017 x86_64 x86_64 x86_64 GNU/Linux
# grep kcmp /proc/kallsyms
ffffffffb60b8890 W sys_kcmp
$ grep CONFIG_CHECKPOINT_RESTORE ../build/v4.14.0-rc3+/.config
# CONFIG_CHECKPOINT_RESTORE is not set
$
So systemd uses it, good fedora kernel config has it:
$ grep CONFIG_CHECKPOINT_RESTORE /boot/config-4.13.4-200.fc26.x86_64
CONFIG_CHECKPOINT_RESTORE=y
[acme@jouet linux]$

perf trace beautify ioctl: Beautify vhost virtio ioctl's 'cmd' arg
Also trying a new approach, using a copy of uapi/linux/vhost.h we auto
generate the string tables, then include it in the ioctl cmd beautifier.
This way either the KVM developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
E.g., doing syswide tracing grepping for the newly beautified VHOST

^C
'-e ioctl' uses tracepoint filters, in time this will be replaces by
eBPF filters hooked at the syscall tracepoints and that "grep VHOST"
will also be done with eBPF, right at the kernel, to reduce overhead.

perf trace: Beautify 'move_mount' arguments
Use existing beautifiers for the first 4 args (to/from fds, pathnames)
and wire up the recently introduced move_mount flags table generator.
Now it should be possible to just use:
perf trace -e move_mount
As root and see all move_mount syscalls with its args beautified, except
for the filenames, that need work in the augmented_raw_syscalls.c eBPF
helper to pass more than one, see comment in the
augmented_raw_syscalls.c source code, the other args should work in all
cases, i.e. all that is needed can be obtained directly from the
raw_syscalls:sys_enter tracepoint args.
Running without the strace "skin" (.perfconfig setting output formatting
switches to look like strace output + BPF to collect strings, as we
still need to support collecting multiple string args for the same
syscall, like with move_mount):
# cat sys_move_mount.c

perf trace beauty prctl: Generate 'option' string table from kernel headers
This is one more case where the way that syscall parameter values are
defined in kernel headers are easy to parse using a shell script that
will then generate the string table that gets used by the prctl 'option'
argument beautifier.
This way as soon as the header syncronization mechanism in perf's build
system detects a change in a copy of a kernel ABI header and that file
is syncronized, we get 'perf trace' updated automagically.
Further work needed for the PR_SET_ values, as well for using eBPF to
copy the non-integer arguments to/from the kernel.
E.g.: System wide prctl tracing:
# perf trace -e prctl

static const char *x86_irq_vectors[] = {

Now its just a matter of using it, associating it to tracepoint arguments named
'vector', all of which can be correctly used with this table, for int args.
At some point we should move tools/perf/trace/beauty to tools/beauty/,
so that it can be used more generally and even made available externally
like libbpf, libperf, libtraceevent, etc.

perf stat: Enable counting events for BPF programs
Introduce 'perf stat -b' option, which counts events for BPF programs, like:
[root@localhost ~]# ~/perf stat -e ref-cycles,cycles -b 254 -I 1000
1.487903822 115,200 ref-cycles
1.487903822 86,012 cycles
2.489147029 80,560 ref-cycles
2.489147029 73,784 cycles
3.490341825 60,720 ref-cycles
3.490341825 37,797 cycles
4.491540887 37,120 ref-cycles
4.491540887 31,963 cycles
The example above counts 'cycles' and 'ref-cycles' of BPF program of id
254. This is similar to bpftool-prog-profile command, but more
flexible.
'perf stat -b' creates per-cpu perf_event and loads fentry/fexit BPF
programs (monitor-progs) to the target BPF program (target-prog). The
monitor-progs read perf_event before and after the target-prog, and
aggregate the difference in a BPF map. Then the user space reads data
from these maps.
A new 'struct bpf_counter' is introduced to provide a common interface
that uses BPF programs/maps to count perf events.
Committer notes:
Removed all but bpf_counter.h includes from evsel.h, not needed at all.
Also BPF map lookups for PERCPU_ARRAYs need to have as its value receive
buffer passed to the kernel libbpf_num_possible_cpus() entries, not
evsel__nr_cpus(evsel), as the former uses
/sys/devices/system/cpu/possible while the later uses
/sys/devices/system/cpu/online, which may be less than the 'possible'
number making the bpf map lookup overwrite memory and cause hard to
debug memory corruption.
We need to continue using evsel__nr_cpus(evsel) when accessing the
perf_counts array tho, not to overwrite another are of memory :-)

perf stat: Introduce 'bperf' to share hardware PMCs with BPF
The perf tool uses performance monitoring counters (PMCs) to monitor
system performance. The PMCs are limited hardware resources. For
example, Intel CPUs have 3x fixed PMCs and 4x programmable PMCs per cpu.
Modern data center systems use these PMCs in many different ways: system
level monitoring, (maybe nested) container level monitoring, per process
monitoring, profiling (in sample mode), etc. In some cases, there are
more active perf_events than available hardware PMCs. To allow all
perf_events to have a chance to run, it is necessary to do expensive
time multiplexing of events.
On the other hand, many monitoring tools count the common metrics
(cycles, instructions). It is a waste to have multiple tools create
multiple perf_events of "cycles" and occupy multiple PMCs.
bperf tries to reduce such wastes by allowing multiple perf_events of
"cycles" or "instructions" (at different scopes) to share PMUs. Instead
of having each perf-stat session to read its own perf_events, bperf uses
BPF programs to read the perf_events and aggregate readings to BPF maps.
Then, the perf-stat session(s) reads the values from these BPF maps.
Please refer to the comment before the definition of bperf_ops for the
description of bperf architecture.
bperf is off by default. To enable it, pass --bpf-counters option to
perf-stat. bperf uses a BPF hashmap to share information about BPF
programs and maps used by bperf. This map is pinned to bpffs. The
default path is /sys/fs/bpf/perf_attr_map. The user could change the
path with option --bpf-attr-map.

perf ftrace: Add -b/--use-bpf option for latency subcommand
The -b/--use-bpf option is to use BPF to get latency info of kernel
functions. It'd have better performance impact and I observed that
latency of same function is smaller than before when using BPF.
Committer testing:
# strace -e bpf perf ftrace latency -b -T __handle_mm_fault -a sleep 1

perf trace: Migrate BPF augmentation to use a skeleton
Previously a BPF event of augmented_raw_syscalls.c could be used to
enable augmentation of syscalls by perf trace. As BPF events are no
longer supported, switch to using a BPF skeleton which when attached
explicitly opens the sysenter and sysexit tracepoints.
The dump map is removed as debugging wasn't supported by the
augmentation and bpf_printk can be used when necessary.
Remove tools/perf/examples/bpf/augmented_raw_syscalls.c so that the
rename/migration to a BPF skeleton captures that this was the source.
Committer notes:
Some minor stylistic changes to help visualizing the diff.
Use libbpf_strerror when failing to load the augmented raw syscalls BPF.
Use bpf_object__for_each_program(prog, trace.skel->obj) to disable auto
attachment for all but the sys_enter, sys_exit tracepoints, to avoid
having to add extra lines as we go adding support for more pointer
receiving syscalls.

It shows we don't clean up properly the fixdep objects, so adding
special rule for that.

perf jevents: Program to convert JSON file
This is a modified version of an earlier patch by Andi Kleen.
We expect architectures to create JSON files describing the performance
monitoring (PMU) events that each CPU model/family of the architecture
supports.
Following is an example of the JSON file entry for an x86 event:
[
...
{
"EventCode": "0x00",
"UMask": "0x01",
"EventName": "INST_RETIRED.ANY",
"BriefDescription": "Instructions retired from execution.",
"PublicDescription": "Instructions retired from execution.",
"Counter": "Fixed counter 1",
"CounterHTOff": "Fixed counter 1",
"SampleAfterValue": "2000003",
"SampleAfterValue": "2000003",
"MSRIndex": "0",
"MSRValue": "0",
"TakenAlone": "0",
"CounterMask": "0",
"Invert": "0",
"AnyThread": "0",
"EdgeDetect": "0",
"PEBS": "0",
"PRECISE_STORE": "0",
"Errata": "null",
"Offcore": "0"
},
...
]
All the PMU events supported by a CPU model/family must be grouped into
"topics" such as "Pipelining", "Floating-point", "Virtual-memory" etc.
All events belonging to a topic must be placed in a separate JSON file
(eg: "Pipelining.json") and all the topic JSON files for a CPU model must
be in a separate directory.
Eg: for the CPU model "Silvermont_core":
$ ls tools/perf/pmu-events/arch/x86/Silvermont_core
Floating-point.json
Memory.json
Other.json
Pipelining.json
Virtualmemory.json
Finally, to allow multiple CPU models to share a single set of JSON files,
architectures must provide a mapping between a model and its set of events:
$ grep Silvermont tools/perf/pmu-events/arch/x86/mapfile.csv
GenuineIntel-6-4D,V13,Silvermont_core,core
GenuineIntel-6-4C,V13,Silvermont_core,core
which maps each CPU, identified by [vendor, family, model, version, type]
to a directory of JSON files. Thus two (or more) CPU models support the
set of PMU events listed in the directory.
tools/perf/pmu-events/arch/x86/Silvermont_core/
Given this organization of files, the program, jevents:
- locates all JSON files for each CPU-model of the architecture,
- parses all JSON files for the CPU-model and generates a C-style
"PMU-events table" (pmu-events.c) for the model
- locates a mapfile for the architecture
- builds a global table, mapping each model of CPU to the corresponding
PMU-events table.
The 'pmu-events.c' is generated when building perf and added to libperf.a.
The global table pmu_events_map[] table in this pmu-events.c will be used
in perf in a follow-on patch.
If the architecture does not have any JSON files or there is an error in
processing them, an empty mapping file is created. This would allow the
build of perf to proceed even if we are not able to provide aliases for
events.
The parser for JSON files allows parsing Intel style JSON event files. This
allows to use an Intel event list directly with perf. The Intel event lists
can be quite large and are too big to store in unswappable kernel memory.
The conversion from JSON to C-style is straight forward. The parser knows
(very little) Intel specific information, and can be easily extended to
handle fields for other CPUs.
The parser code is partially shared with an independent parsing library,
which is 2-clause BSD licensed. To avoid any conflicts I marked those
files as BSD licensed too. As part of perf they become GPLv2.
Committer notes:
Fixes:
1) Limit maxfds to 512 to avoid nftd() segfaulting on alloca() with a
big rlim_max, as in docker containers - acme
2) Make jevents a hostprog, supporting cross compilation - jolsa
3) Use HOSTCC for jevents final step - acme
4) Define _GNU_SOURCE for asprintf, as we can't use CC's EXTRA_CFLAGS,
that has to have --sysroot on the Android NDK 24 - acme
5) Removed $(srctree)/tools/perf/pmu-events/pmu-events.c from the
'clean' target, it is generated on $(OUTPUT)pmu-events/pmu-events.c,
which is already taken care of in the original patch - acme

perf trace beauty ioctl: Beautify DRM ioctl cmds
This time we try a new approach, using uapi/drm/ copies of drm.h and
i915_drm.h we auto generate the string tables, then include it in the
ioctl cmd beautifier.
This way either the DRM developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
Either way the time from a new command being added to when 'perf trace'
gets to know it is greatly shortened, for instance:
# strace -p 22401 -e ioctl
ioctl(8, DRM_IOCTL_I915_GEM_BUSY, 0x7ffc934f7600) = 0

perf trace: Beautify 'fsconfig' arguments
Use existing beautifiers for the first arg, fd, assigned using the
heuristic that looks for syscall arg names and associates SCA_FD with
'fd' named argumes, and wire up the recently introduced fsconfig cmd
table generator.
Now it should be possible to just use:
perf trace -e fsconfig
As root and see all fsconfig syscalls with its args beautified, more
work needed to look at the command and according to it handle the 'key',
'value' and 'aux' args, using the 'fcntl' and 'futex' beautifiers as a
starting point to see how to suppress sets of these last three args that
may not be used by the 'cmd' arg, etc.

perf trace: Beautify 'fsmount' arguments
Use existing beautifiers for the first arg, fd, assigned using the
heuristic that looks for syscall arg names and associates SCA_FD with
'fd' named argumes, and wire up the recently introduced fsmount
attr_flags table generator.
Now it should be possible to just use:
perf trace -e fsmount
As root and see all fsmount syscalls with its args beautified.

perf trace: Beautify 'fspick' arguments
Use existing beautifiers for the first 2 args (dfd, path) and wire up
the recently introduced fspick flags table generator.
Now it should be possible to just use:

As root and see all move_mount syscalls with its args beautified, either
using the vfs_getname perf probe method or using the
augmented_raw_syscalls.c eBPF helper to get the pathnames, the other
args should work in all cases, i.e. all that is needed can be obtained
directly from the raw_syscalls:sys_enter tracepoint args.

perf trace: Beautify 'move_mount' arguments
Use existing beautifiers for the first 4 args (to/from fds, pathnames)
and wire up the recently introduced move_mount flags table generator.
Now it should be possible to just use:
perf trace -e move_mount
As root and see all move_mount syscalls with its args beautified, except
for the filenames, that need work in the augmented_raw_syscalls.c eBPF
helper to pass more than one, see comment in the
augmented_raw_syscalls.c source code, the other args should work in all
cases, i.e. all that is needed can be obtained directly from the
raw_syscalls:sys_enter tracepoint args.
Running without the strace "skin" (.perfconfig setting output formatting
switches to look like strace output + BPF to collect strings, as we
still need to support collecting multiple string args for the same
syscall, like with move_mount):

perf trace beautify ioctl: Beautify sound ioctl's 'cmd' arg
This time we try a new approach, using a copy of uapi/sound/asound.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.
This way either the sound developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
E.g.:
# perf trace -p 22084 -e ioctl 2>&1 | head -5

perf trace beauty: Beautify pkey_{alloc,free,mprotect} arguments
Reuse 'mprotect' beautifiers for 'pkey_mprotect'.
System wide tracing pkey_alloc, pkey_free and pkey_mprotect calls, with
backtraces:
# perf trace -e pkey_alloc,pkey_mprotect,pkey_free --max-stack=5
0.000 ( 0.011 ms): pkey/7818 pkey_alloc(init_val: DISABLE_ACCESS|DISABLE_WRITE) = -1 EINVAL Invalid argument
syscall (/usr/lib64/libc-2.25.so)
pkey_alloc (/home/acme/c/pkey)
0.022 ( 0.003 ms): pkey/7818 pkey_mprotect(start: 0x7f28c3890000, len: 4096, prot: READ|WRITE, pkey: -1) = 0
syscall (/usr/lib64/libc-2.25.so)
pkey_mprotect (/home/acme/c/pkey)
0.030 ( 0.002 ms): pkey/7818 pkey_free(pkey: -1 ) = -1 EINVAL Invalid argument
syscall (/usr/lib64/libc-2.25.so)
pkey_free (/home/acme/c/pkey)
The tools/include/uapi/asm-generic/mman-common.h file is used to find
the access rights defines for the pkey_alloc syscall second argument.
Since we have the detector of changes for the tools/include header files
versus its kernel origin (include/uapi/asm-generic/mman-common.h), we'll
get whatever new flag appears for that argument automatically.
This method should be used in other cases where it is easy to generate
those flags tables because the header has properly namespaced defines
like PKEY_DISABLE_ACCESS and PKEY_DISABLE_WRITE.

perf trace beautify ioctl: Beautify KVM ioctl's 'cmd' arg
Also trying a new approach, using a copy of uapi/linux/kvm.h we auto
generate the string tables, then include it in the ioctl cmd beautifier.
This way either the KVM developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
E.g., a tracing a process and its threads, but would work for system wide as
well, just drop that '-p 21238', to see ioctls for DRM, tty, sound, etc:

[root@jouet linux]#
Since there are clashes in _IOC_NR() for some cases, notably ioctls with
PPC_ and ARM_ in its name and some that depend on some internal state to
be valid, but use the same number as others, those were removed in the
shell script that builds the table, tools/perf/trace/beauty/kvm_ioctl.sh.
Since so far we're supporting only x86 in the 'cmd' ioctl arg beautifier
in perf trace, we can leave fully supporting these ioctls for later.
There are some more to handle here, notably the one for /dev/vhost-net, will
come later.

perf trace beautify ioctl: Beautify vhost virtio ioctl's 'cmd' arg
Also trying a new approach, using a copy of uapi/linux/vhost.h we auto
generate the string tables, then include it in the ioctl cmd beautifier.
This way either the KVM developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
E.g., doing syswide tracing grepping for the newly beautified VHOST
ioctls:

^C
'-e ioctl' uses tracepoint filters, in time this will be replaces by
eBPF filters hooked at the syscall tracepoints and that "grep VHOST"
will also be done with eBPF, right at the kernel, to reduce overhead.

perf trace beauty kcmp: Beautify arguments
For some unknown reason there is no entry in tracefs's syscalls for
kcmp, i.e. no tracefs/events/syscalls/sys_{enter,exit}_kcmp, so we need
to provide a data dictionary for the fields.
To beautify the 'type' argument we automatically generate a strarray
from tools/include/uapi/kcmp.h, the idx1 and idx2 args, nowadays used
only if type == KCMP_FILE, are masked for all the other types and a
lookup is made for the thread and fd to show the path, if possible,
getting it from the probe:vfs_getname if in place or from procfs, races
allowing.
A system wide strace like tracing session, with callchains shows just
one user so far in this fedora 25 machine:
# perf trace --max-stack 5 -e kcmp
<SNIP>
1502914.400 ( 0.001 ms): systemd/1 kcmp(pid1: 1 (systemd), pid2: 1 (systemd), type: FILE, idx1: 271<socket:[4723475]>, idx2: 25<socket:[4788686]>) = -1 ENOSYS Function not implemented
syscall (/usr/lib64/libc-2.25.so)
same_fd (/usr/lib/systemd/libsystemd-shared-233.so)

1502914.407 ( 0.001 ms): systemd/1 kcmp(pid1: 1 (systemd), pid2: 1 (systemd), type: FILE, idx1: 270<socket:[4726396]>, idx2: 25<socket:[4788686]>) = -1 ENOSYS Function not implemented

service_add_fd_store (/usr/lib/systemd/systemd)
service_notify_message.lto_priv.127 (/usr/lib/systemd/systemd)
<SNIP>
The backtraces seem to agree this is really kcmp(), but this system
doesn't have the sys_kcmp(), bummer:
# uname -a
Linux jouet 4.14.0-rc3+ #1 SMP Fri Oct 13 12:21:12 -03 2017 x86_64 x86_64 x86_64 GNU/Linux
# grep kcmp /proc/kallsyms
ffffffffb60b8890 W sys_kcmp
$ grep CONFIG_CHECKPOINT_RESTORE ../build/v4.14.0-rc3+/.config
# CONFIG_CHECKPOINT_RESTORE is not set
$
So systemd uses it, good fedora kernel config has it:
$ grep CONFIG_CHECKPOINT_RESTORE /boot/config-4.13.4-200.fc26.x86_64
CONFIG_CHECKPOINT_RESTORE=y
[acme@jouet linux]$

perf trace beauty prctl: Generate 'option' string table from kernel headers
This is one more case where the way that syscall parameter values are
defined in kernel headers are easy to parse using a shell script that
will then generate the string table that gets used by the prctl 'option'
argument beautifier.
This way as soon as the header syncronization mechanism in perf's build
system detects a change in a copy of a kernel ABI header and that file
is syncronized, we get 'perf trace' updated automagically.
Further work needed for the PR_SET_ values, as well for using eBPF to
copy the non-integer arguments to/from the kernel.
E.g.: System wide prctl tracing:
# perf trace -e prctl

libbeauty: Hook up the x86 irq_vectors table generator
I.e. after running:
$ make -C tools/perf O=/tmp/build/perf
We end up with:
$ cat /tmp/build/perf/trace/beauty/generated/x86_arch_irq_vectors_array.c
static const char *x86_irq_vectors[] = {
[0x02] = "NMI",
[0x12] = "MCE",
[0x20] = "IRQ_MOVE_CLEANUP",
[0x80] = "IA32_SYSCALL",
[0xec] = "LOCAL_TIMER",
[0xed] = "HYPERV_STIMER0",
[0xee] = "HYPERV_REENLIGHTENMENT",
[0xef] = "MANAGED_IRQ_SHUTDOWN",
[0xf0] = "POSTED_INTR_NESTED",
[0xf1] = "POSTED_INTR_WAKEUP",
[0xf2] = "POSTED_INTR",
[0xf3] = "HYPERVISOR_CALLBACK",
[0xf4] = "DEFERRED_ERROR",
[0xf6] = "IRQ_WORK",
[0xf7] = "X86_PLATFORM_IPI",
[0xf8] = "REBOOT",
[0xf9] = "THRESHOLD_APIC",
[0xfa] = "THERMAL_APIC",
[0xfb] = "CALL_FUNCTION_SINGLE",
[0xfc] = "CALL_FUNCTION",
[0xfd] = "RESCHEDULE",
[0xfe] = "ERROR_APIC",
[0xff] = "SPURIOUS_APIC",
};
$
Now its just a matter of using it, associating it to tracepoint arguments named
'vector', all of which can be correctly used with this table, for int args.
At some point we should move tools/perf/trace/beauty to tools/beauty/,
so that it can be used more generally and even made available externally
like libbpf, libperf, libtraceevent, etc.

perf beauty: Hook up the x86 MSR table generator
This way we generate the source with the table for later use by plugins,
etc.
I.e. after running:
$ make -C tools/perf O=/tmp/build/perf
We end up with:
$ head /tmp/build/perf/trace/beauty/generated/x86_arch_MSRs_array.c
static const char *x86_MSRs[] = {
[0x00000000] = "IA32_P5_MC_ADDR",
[0x00000001] = "IA32_P5_MC_TYPE",
[0x00000010] = "IA32_TSC",
[0x00000017] = "IA32_PLATFORM_ID",
[0x0000001b] = "IA32_APICBASE",
[0x00000020] = "KNC_PERFCTR0",
[0x00000021] = "KNC_PERFCTR1",
[0x00000028] = "KNC_EVNTSEL0",
[0x00000029] = "KNC_EVNTSEL1",
$
Now its just a matter of using it, first in a libtracevent plugin.
At some point we should move tools/perf/trace/beauty to tools/beauty/,
so that it can be used more generally and even made available externally
like libbpf, libperf, libtraevent, etc.

perf trace: Beautify 'sync_file_range' arguments
Use existing beautifiers for the first arg, fd, assigned using the
heuristic that looks for syscall arg names and associates SCA_FD with
'fd' named argumes, and wire up the recently introduced sync_file_range
flags table generator.
Now it should be possible to just use:
perf trace -e sync_file_range
As root and see all sync_file_range syscalls with its args beautified.
Doing a syscall strace like session looking for this syscall, then run
postgresql's initdb command:
# perf trace -e sync_file_range
<SNIP>
initdb/1332 sync_file_range(6</var/lib/pgsql/data/global/1260_fsm>, 0, 0, SYNC_FILE_RANGE_WRITE) = 0

perf tools: Stop depending on .git files for building PERF-VERSION-FILE
This essentially reverts commit c72e3f04b45fb2e5 ("tools/perf/build:
Speed up git-version test on re-make") and commit 4e666cdb06eede20
("perf tools: Fix dependency for version file creation")
In commit c72e3f04b45fb2e5 ("tools/perf/build: Speed up git-version test
on re-make"), a makefile dependency on .git/HEAD was added. The
background is that running PERF-VERSION-FILE is relatively slow, and
commands like "git describe" are particularly slow.
In commit 4e666cdb06eede20 ("perf tools: Fix dependency for version file
creation"), an additional dependency on .git/ORIG_HEAD was added, as
.git/HEAD may not change for "git reset --hard HEAD^" command. However,
depending on whether we're on a branch or not, a "git cherry-pick" may
not lead to the version being updated.
As discussed with the git community in [0], using git internal files for
dependencies is not reliable. Commit 4e666cdb06ee also breaks some build
scenarios [1].
As mentioned, c72e3f04b45fb2e5 ("tools/perf/build: Speed up git-version
test on re-make") was added to speed up the build. However in commit
7572733b84997d23 ("perf tools: Fix version kernel tag") we removed the
call to "git describe", so just revert Makefile.perf back to same as pre
c72e3f04b45fb2e5 ("tools/perf/build: Speed up git-version test on
re-make") and the build should not be so slow, as below:
Pre 7572733b8499:
$> time util/PERF-VERSION-GEN
PERF_VERSION = 5.17.rc8.g4e666cdb06ee
real 0m0.110s
user 0m0.091s
sys 0m0.019s
Post 7572733b8499:

[1] https://lore.kernel.org/linux-perf-users/20220329093120.4173283-1-matthieu.baerts@tessares.net/T/#u
Committer testing:
After a fresh rebuild using 'make -C tools/perf O=/tmp/build/perf install-bin':
$ perf -v
perf version 5.17.g162f9db407b6
$ git log --oneline -1
162f9db407b6a6e5 (HEAD -> perf/core) perf tools: Stop depending on .git files for building PERF-VERSION-FILE
$
Now using a detached tarball, i.e. outside the kernel source tree:
$ ls -la perf*tar
ls: cannot access 'perf*tar': No such file or directory
$ make perf-tar-src-pkg
TAR
PERF_VERSION = 5.17.g31d10b3ef133
$ ls -la perf*tar
