I need to clean this up a bit after the latest changes :(

Also this is missing docs.

If you want to schedule another build, you need to add the 🔨 test-with-buildbots label again.

Hi, Linux perf supports DWARF unwinding using either libunwind or libdw. And they might have different quality of supports. Do you know which one you used (and worked)? And please share the problems or symptoms you are seeing in more detail, thanks!

Thanks a lot for the help @namhyung

Hi, Linux perf supports DWARF unwinding using either libunwind or libdw. And they might have different quality of supports. Do you know which one you used (and worked)?

Do you know how can I check this? The closest I got is to check symbols in thee binary distributed with the distro:

nm /usr/lib/linux-tools/5.15.0-88-generic/perf  | grep libunwind
00000000008a2888 V arm64_unwind_libunwind_ops
000000000039ad90 T libunwind__arch_reg_id
0000000000672fe0 D local_unwind_libunwind_ops
0000000000673000 d _unwind_libunwind_ops
00000000008a2890 V x86_32_unwind_libunwind_ops

from that looks like is using lubunwind in Ubuntu and Arch Linux.

And please share the problems or symptoms you are seeing in more detail, thanks!

To illustrate the problems I am going to execute the following steps in an Ubuntu 22.04.3 system. These are the relevant versions:

$ uname -a
Linux shaphire 5.15.0-89-generic #99-Ubuntu SMP Mon Oct 30 20:42:41 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 22.04.3 LTS
Release:	22.04
Codename:	jammy
$ perf --version
perf version 5.15.126

Consider this Python file:

def foo():
    bar()

def bar():
    baz()

def baz():
    x = 0
    for _ in range(50_000_000):
        x += 1

foo()

Running perf with this integration activated with a Python compiled with no frame pointers (the default) over the file:

$ perf record --call-graph dwarf,65528  -g  -F99 -k1 -- ./python -Xperfjit lol.py
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.044 MB perf.data (182 samples) ]
$ perf inject -j -i perf.data -o jit.data

This produces a bunch of elf files that look sane. For example

$ readelf -a  /tmp/jitted-253980-17.so
readelf -a  /tmp/jitted-282493-125.so

Other things to notice:

  • In Arch Linux both unwinding and symbol resolving works, even under the same kernel version. I am not sure what other differences there are with the perf version shipped here that could make it work.

Hi, Linux perf supports DWARF unwinding using either libunwind or libdw. And they might have different quality of supports. Do you know which one you used (and worked)?

Do you know how can I check this?

Try perf version --build-options | grep libunwind.

Let's do this one by one. So on Ubuntu, it basically gets the stack trace correctly but no symbols in the python trampolines, right?

One thing I noticed is warnings in the readelf output for the symbol table.

Symbol table '.symtab' contains 2 entries:
   Num:    Value          Size Type    Bind   Vis      Ndx Name
     0: 0000000000000000     0 NOTYPE  LOCAL  DEFAULT  UND
readelf: Warning: local symbol 0 found at index >= .symtab's sh_info value of 0
     1: 0000000000000040     8 FUNC    LOCAL  DEFAULT    1 py::isfile:<froz[...]
readelf: Warning: local symbol 1 found at index >= .symtab's sh_info value of 0

I don't know what .symtab.sh_info means. One thing I can find so far is the Solaris Linker and Libraries Guide:

Symbol Table Layout and Conventions
...
The global symbols immediately follow the local symbols in the symbol table. The first global symbol is identified by the symbol table sh_info value. Local and global symbols are always kept separate in this manner, and cannot be mixed together.

But I'm not sure if it's the case for Linux as my test binary has mixed global and local symbols.

Also, I'm curious how exactly the JIT code maps to the address. Can you please run this?

perf script -i jit.data --show-mmap-events | grep jit

The fixes were added to v6.8 originally and then backported to v6.7.2. So and kernel versions later would be fine.

But the more important ones are long-term stable (LTS) versions which are v6.6 and v6.1. I've checked v6.6.14 has the fixes but v6.1.x doesn't. I asked the stable team to add the fixes to v6.1 already. I'll let you know once it's done and I got the version number.

Again, this is only perf tool issue and nothing related to the kernel. But the perf tools just use the same version numbers because it's maintained in the same source tree.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

You are in 'detached HEAD' state. You can look around, make experimental

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

@namhyung I found another problem. If perf is compiled without libunwind it looks like the unwinding still doesn't work when Python is compiled with -O2 or higher:

perf record --call-graph dwarf,65528  -g  -F99 -k1 -- ./python -Xperfjit lol.py
perf inject -j -i perf.data -o jit.data
perf script -i jit.data | grep 'py::' | sort | uniq -c

that shows:

with libunwind-enabled perf and

with perf without libunwind support. Any idea of what may be going on?

Hummmm, wait, this may be something with the versions. I tried to compile the current version on main from the kernel git repo (commit dd5a440a31fae6e459c0d6271dddd62825505361) and that works with libunwind, but the perf version shipped in Arch Linux (perf version 6.7-3) doesn't. Can you confirm that this version should have the fix?

Ah, nevermind, all good. Seems that the version in arch linux it's using the v6.7 tag:

https://gitlab.archlinux.org/archlinux/packaging/packages/linux-tools/-/blob/main/.SRCINFO?ref_type=heads#L39

which I suppose it's before 6.7.2 (I was confused by the weird output of perf version)

Yeah, the version number after - is added by distro, usually. -rcN is an exception but I don't think they will ship the rc kernels. v6.7 is before v6.7.2 and doesn't have the fix.

That can't be correct since on aarch64 every insn is 4-byte aligned.

It's correct as the code alignment factor on aarch64 is 4 instead of 1 such as on x86_64.
