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

I.e. looking for futex calls that take at least 15ms, system wide, during a one
second window. Now to get callchains into 'trace' to figure out what are those
locks :-)

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'

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

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

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 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 beautify ioctl: Beautify perf ioctl's 'cmd' arg
Also trying a new approach, using the copy of uapi/linux/perf_event.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.
This way either the perf 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., looking at some of the perf ioctls issued by the 'perf test' test cases:
# (perf trace -e perf_event_open,ioctl perf test) 2>&1 | egrep "(cmd: PERF_|perf_event_open)"

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

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 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

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: 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:
# perf trace -e ioctl -p 21238 2>&1 | grep -v KVM_RUN

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

'-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: 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 ) ...

0.253 (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 :-)

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 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 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:

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.

^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 ioctl: Beautify perf ioctl's 'cmd' arg
Also trying a new approach, using the copy of uapi/linux/perf_event.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.
This way either the perf 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., looking at some of the perf ioctls issued by the 'perf test' test cases:
# (perf trace -e perf_event_open,ioctl perf test) 2>&1 | egrep "(cmd: PERF_|perf_event_open)"

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
