Ok, the fact that the "AI" (NPU) chip controller inside Intel's new Meteor Lake CPUs uses SPARC instruction set (from 1990?) was not on my bingo cards for this year. https://chipsandcheese.com/2024/04/22/intel-meteor-lakes-npu/

jarkko@Andi Luckily I’ve recently tested SGX cgroups patches with Tumbleweed, i.e. know how to compile equivalent distro kernel (as it is made for OpenSUSE) for any possible kernel tree :-) So can easily try this out once the bandwidth is available.
It is maybe even easier than Ubuntu kernel (which has been easiest so far):
./scripts/install-git-hooks # not sure whether this is really required
./scripts/tar-up.sh
export LINUX_GIT=~/work/linux-tpmdd # clean clone swithed to branch of your choice
./scripts/osc_wrapper kernel-source/kernel-default.spec
The packages land to /var/tmp/build-root/standard-x86_64/home/abuild/rpmbuild/RPMS/x86_64. And obviously needs to be signed with a MOK key if secure boot is turned on.

e.g. if have such prefix missing from some function that i maintain and i get a patch with that rationale, i most likely ack it despite being somewhat cosmetic change.

There was some other bug that I even fixed in OpenSUSE installation but I cannot remember what it was :-) I reported it here to mastodon only. I need to look that one up too if I ever get access to that bugzilla.

If XE driver is a fix, then this is also tumbleweed bug, ain't it @vbabka ?

GPU HANG is emitted by error_msg. Would be better of by being i915_error_msg or i915_error for easier grepping and inserting probes and this also supports it:
$ git grep error_msg|wc -l

@timojyrinki unrelated side-note, i don’t undestand why people put this cruft to new code in kernel:
* Authors:
* Eric Anholt <eric@anholt.net>
* Keith Packard <keithp@keithp.com>
* Mika Kuoppala <mika.kuoppala@intel.com>
Nobody cares as Git has author field. Totally useless information.

Still a major turndown, i.e. owning a GPU that cannot do graphics.

another different kind of workload where this does not happen is Bitwig Studio. So this is directly connected to this graphics card way or another.
I disabled upscaling (i.e. intel_pstate) but have not yet tried also disabling downscaling, which could be good test perhaps.
