Hi all,
this patch adds support to build the linux-perf<version> package
that includes the kernel specific perf tooling.
During implementation I tried two different approaches:
1. package as part of the kernel receipt (as Debian does)
2. package as a regular package (similar to how the kselftest is packaged)
This RFC implements approach 2 but tries to be as close as possible
to the Debian upstream packaging.
By that, we use the same patches from Debian upstream to build our package.
Note, that these are dependent on the exact kernel version.
Here, I used the latest available bugfix version from upstream (4.19.160).
Perf should then be compatible with 4.19 kernels (only partially tested).
A major obstacle in implementing approach 1 was that the patches for linux-tools
are not trivial and have to match with the corresponding kernel version.
Writing that in a way that works for various kernel versions was something I
was not able to accomplish.
Hence, I decided that it might be better to avoid that much complexity in the
kernel receipt. Most users might not need the tools anyways, but probably a
custom kernel.
Finally, this patch also builds the kernel specific python bindings of perf.
This patch has already been sent upstream, but is not yet integrated in Debian.
For reference, see here: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=860957
Best regards,
Felix Mößbauer

This patch adds the linux-perf-4.19 package for a kernel
that is build with ISAR.
As the perf binaries have to be version specific, we patch
the corresponding files from the kernel tools source to incorporate
the major and minor version number.
These patches are copied over from the official debianization of perf
that is done in the src:linux package.
Additionally, we package the perf python bindings as well and provide
them as module "perf_4_19" (in the tools-perf-python.patch).
As this debianization is not part of the kernel receipt, the perf
package can be based on a different patch version of the kernel.
While this might be intended, it is now the responibility of the
user to ensure that both the kernel and the linux-perf-<version>
packages are compatible.

2.20.1
that is build with ISAR.
As the perf binaries have to be version specific, we patch
the corresponding files from the kernel tools source to incorporate
the major and minor version number.
These patches are copied over from the official debianization of perf
that is done in the src:linux package.
Additionally, we package the perf python bindings as well and provide
them as module "perf_4_19" (in the tools-perf-python.patch).
As this debianization is not part of the kernel receipt, the perf
package can be based on a different patch version of the kernel.
While this might be intended, it is now the responibility of the
user to ensure that both the kernel and the linux-perf-<version>
packages are compatible.

in the kernel and have a single kernel source package. I wonder why Debian
hasn't upstreamed that yet -- whether there were any technical problems, or
just no one happened to look at that. That said, I personally could live with
this till we have a better solution.
If nothing works, maybe we could relax the goal of being able to build any
given kernel version and experiment with conditional execution paths.
With kind regards,
Baurzhan.

Hi,
i think perf support in general is something we clearly want to have.
As far as i remember Cedric might be interested as well, adding him to
CC.
Maybe a split into the basic support and the python bindings is useful.
Because those python bindings are pretty different from upstream, and
they probably deserve a test-package if we agree that we want to
support them in isar.

For a v2 perf should be added to scripts/ci_build or the local.conf
used by it which will probably reveal problems with bullseye and
stretch, maybe != x86 as well
You will get access to a Siemens internal CI for that and other future
contributions.

Hi,
today I implemented the packaging in the kernel recipe and fixed some
nasty aspects like exact version numbers in the patches.
I'll send this patch to the mailing list as well.
One issue is still that we need per-kernel patches.
If anything in the original makefile of perf changed, our patches do not apply.
That lead me to the initial approach with having a dedicated package with multiple recipes,
to have different patch-sets per kernel version (and put it into the responsibility of the user).
Another issue with the kernel-recipe approach is that it's no longer possible to use the Debian kernel but customize / fix the linux-perf-<version> package.
Maybe we need both.
@Schild, Henning (T RDA IOT SES-DE):
Having the Python stuff in a dedicated commit is definitely a good idea.
It's already in its own patchset. I'll send a v2 to the list as well.
Best regards,
Felix

But i guess debian has perf packages for kernels taken from them. So
this would only be a problem if one had a need to add python binding
support to such a kernel. In which case one could always rebuild the
same sources+config under another name ...

Hi,
thanks for your input that is reflected in the following patchsets.
Changes since v1:
- package as part of kernel recipe
- put python patch in dedicated commit
- add support for 5.4 kernels
- enable users to provide custom patches
One pain point is still that we have to copy the patches
from upstream debian. IMO it would be better to just fetch
them, but then we would have to somehow map to a branch on
salsa. Any recommendations?
Best regards,
Felix

This patch builds and packages the version specific bindings of perf
as part of the kernel recipe.
The support can be disabled by setting KERNEL_PACKAGE_PERF="0".
As special patches are needed for each kernel version, support for perf
is automatically disabled for kernels where no patches are provided.
A user of this recipe can provide these patches for a custom kernel
by setting / replacing KERNEL_PERF_PATCHES[<version-major>.<version-minor>].
It is also possible to only patch the linux-perf-<version> package and use
an upstream kernel by adding a dependency to the linux-perf-<version> package.

features that we are missing from the kernel. After that, we will "only"
have to deal with a shrinking number of backports for which we can
provide a view references. When keeping the patches downstream, we will
soon have a huge number of additional patches to carry - or perf support
will even bitrot again with newer kernels.

Hi Jan,
Well... the patches target the Makefiles of perf in the kernel sources. And they add things like versioning (e.g. perf_4.19 instead of perf) and directory layouts of the install targets.
That's something which is (IMO) unlikely to be accepted by the kernel itself.
But apparently, nobody had tried to upstream this yet (according to a quick search on the LKML).
With the current approach, it cannot really rot.
When a new kernel is added, it is disabled per default.
Nonetheless, I don't see another strategy than just manually porting this to each new KR.
Best regards,
Felix

Hard-coded Debian-specific settings are not going to be accepted. Smart

Hi Baurzhan,
Thanks for the review.
I'll change that in the next version.
In the meantime, I discovered that there are still a couple of things missing for Debian bullseye.
They added version bindings between linux-perf and linux-perf-<version>, so we have to build the linux-perf package as well.
I'll do that in v2 as well.
Apart from that: IMO doing the debianization of the kernel tools (also kselftest) in the kernel recipe is way better than having it in a dedicated recipe.
Using this approach, it is also possible to use an upstream kernel, but our perf package.
Technically, we then have to fetch and build the whole kernel manually, but only the perf packages are installed.
That's a bit of extra work (which could be avoided if we check inside the kernel recipe which target is attracted. Don't know if that's possible).
One issue with mixing upstream kernels and custom tools is still that we do not have a guarantee that these will still work when the kernel gets updated via APT.
Maybe we should pin the kernel as well...
Best regards,
Felix

some control variables to the kernel recipe that will decide which
packages are going to be built out of it.

This patch adds a wrapper around the versioned python bindings of
perf. The wrapper takes care of detecting the current kernel version
and loading the perf_<version> module. Then, it mapps this module
to just perf, so downstream python modules just have to `import perf`
instead of the versioned version.

Hi Anton,
there has been some back and forth on how to package perf and its python bindings.
IMO the out-of-tree packaging provides the most promising solution here,
as the kernel versions do not have to match exactly.
Also with debian bullseye things changed again, as an exact-version binding was
introduced between linux-perf and linxu-perf-<KR>. By that, both have to be
build from the same source package. Now, we build and provide that package as well.
Our final goal for all the effort was to get the python bindings of perf packaged.
These are missing in upstream debian. Unfortunately the kernel itself does not
provide any hooks to inject the version "into" the python-binding c source files,
so we have to use patches to inject the version into the c function names.
I already sent that patch to debian but did not get a response yet.
For details, see here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=860957
Anyways, we run this patch series on a bunch of images for both
debian-buster and debian-bullseye (both custom and debian kernels) for a while.
In combination with the wrapper in patch 2, even things like
`import perf` work flawlessly.
Best regards,
Felix

that is build with ISAR.
As the perf binaries have to be version specific, we patch
the corresponding files from the kernel tools source to incorporate
the major and minor version number.
These patches are copied over from the official debianization of perf
that is done in the src:linux package.
Additionally, we package the perf python bindings as well and provide
them as module "perf_<MAJOR>_<MINOR>" (in the tools-perf-python.patch).

As this debianization is not part of the kernel recipe, the perf

While this might be intended, it is now the responibility of the

packages are compatible.
