Hi,
I am perplexed now at 6.12 stable vanilla tree, and I've noticed that after changing just one
line in ./drivers/gpu/drm/xe/tests/xe_migrate.c:226:5-11, all unrelated drivers are being BTF'd, SIGNED,
and INSTALL-ed:

Is there an option to rebuild just the necessary driver that was modified?

From the list of files that were compiled, it seems that drivers/gpu/drm/xe/tests/xe_migrate.c was
not rebult:

But they were only BTF + INSTALL + STRIP + SIGN'ed:

Nothing suggests that "drivers/gpu/drm/xe/tests/xe_migrate.c" is being recompiled, though it was modified,
or at least "touch"-ed.
Is this the expected behaviour?
(I have deliberately skipped "make clean", to see if I can save some building time and grid power.)
Thank you very much.

This happens when the vermagic is changed. The vermagic is linked into
each module. And after relinking all the other steps also need to be
done.
Building the Debian package increases the build number which ends up in
the vermagic and therefore all modules.
Also there is CONFIG_LOCALVERSION_AUTO which may be involved.
> Is there an option to rebuild just the necessary driver that was modified?
With the whole Debian packaging: No idea.
With plain kbuild: make $MAKEFLAGS $PATH_TO_MODULE.ko

Do you have CONFIG_DRM_XE_KUNIT_TEST enabled?
It probably does not make sense to use Debian packaging for a kunit
test. Just use kunit.py directly.

Yes, I use CONFIG_LOCALVERSION_AUTO because it saves a lot of trouble in bisecting.
This vermagic manipulation is beyond my grasp. I understand that modules must match kernel version, for internal ABI often changes. But not between builds of the same source? Am I thinking right?

This could speed up some fixes, thanks :-)

The ABI doesn't change between builds of the same source tree which is
why there are no actual rebuilds ("CC") of all modules.
But your usage of bindeb-pkg bumps the version string
(also without CONFIG_LOCALVERSION_AUTO) and this needs to end up in each
module file which explains the LD/BTF/SIGN/INSTALL steps.

That is actually more precise.

I see. I hoped there is a way around this.
CONFIG_LOCALVERSION_AUTO is very useful when compared to manually keeping tracks of commits.
Once upon a time, about a year or two ago, I told Mr. Bagas Sanjaya how a list of applied diffs
could be added to the kernel manifest instead of just config-${VERSION} and "-dirty" flag.
Thanks.
