[PATCH] drm/xe: Don't emit UTS_RELEASE as part of device coredump

[PATCH] drm/xe: Don't emit UTS_RELEASE as part of device coredump

[Uwe Kleine-König (The Capable Hub)]

UTS_RELEASE changes quite easily (e.g. uncommitted changes in the source
tree or new commits). So when checking if a patch introduces changes to the
resulting binary each usage of UTS_RELEASE is a source of annoyance as
it introduces changes not caused by the change under test.

It's little helpful to emit the kernel version in the device coredump, so
drop the kernel version line from it.

Hello,

I'm not really sure if my assertion above that the kernel version isn't
helpful is actually true.

If yes, there are a few more very similar changes to make:

	$ git grep -E 'drm_p.*UTS_RELEASE' v7.1-rc1 drivers/gpu/
	v7.1-rc1:drivers/gpu/drm/amd/amdgpu/amdgpu_dev_coredump.c:      drm_printf(&p, "kernel: " UTS_RELEASE "\n");
	v7.1-rc1:drivers/gpu/drm/msm/disp/msm_disp_snapshot_util.c:     drm_printf(p, "kernel: " UTS_RELEASE "\n");
	v7.1-rc1:drivers/gpu/drm/msm/msm_gpu.c: drm_printf(&p, "kernel: " UTS_RELEASE "\n");
	v7.1-rc1:drivers/gpu/drm/xe/xe_devcoredump.c:   drm_puts(&p, "kernel: " UTS_RELEASE "\n");

Best regards
Uwe

FTR: If the patch is acceptable, the following should be squashed into
it:

diff --git a/drivers/gpu/drm/xe/xe_devcoredump.c b/drivers/gpu/drm/xe/xe_devcoredump.c

I will wait with a new revision in the hope to get some feedback first.

we know, this is exactly why we use it ;)
We want to be able to differentiate if it is a distro build versus custom build.

That's a driver decision, no?!
We think it is useful and this change breaks the tools that are parsing it.
So, please drop this patch.

Thanks,
Rodrigo.

Would it help to use init_uts_ns.name.release from
init/version-timestamp.c instead of UTS_RELEASE? No rebuilds, info
retained.
