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: Add 'trace' alias to 'perf trace'
Make 'perf trace' more accessible by aliasing it to just 'trace':

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'
#
With this patch:
# trace -e copy_file_range,membarrier,mlock2,pread64,pwrite64,timerfd_create,userfaultfd
8505.733 ( 0.010 ms): gnome-shell/2519 timerfd_create(flags: 524288) = 36

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 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 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

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

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 ) ...

0.253 (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 :-)

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

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
