MTL warnings are still visible in https://github.com/thesofproject/sof/actions/runs/3625503925/jobs/6113619508 but they don't "break the build" any more.

EDIT: same again in https://github.com/thesofproject/sof/actions/runs/3688703910/jobs/6243807588

https://github.com/thesofproject/sof/actions/runs/3625503919/jobs/6113620156 has the stupid "we don't talk about sparse" checkpatch warning and nothing else.

this means, we will see complete MTL sparse output including "address space" warnings in CI, it just won't be a failure? Could you maybe remove "SKIP CI" to let us see what it will look like?

Yes, see link in comment above and in the "Checks" box below.

Only sof-ci/jenkins reads "SKIP CI", Github does not care. Again look at the "Details" box below.

Indeed, thanks! I'm not sure whether it's a good idea to green-wash our failures, but as long as we have the output, I personally can live with it

I don't like it either but it's been red for too long now. I also made sure it's very easy to revert.

Can you approve then?

MTL errors will be fixed after v2.4 is tagged - lets fix instead of hiding. The other patches are fine in this PR.

@lgirdwood re-submitting the other patches is not an issue but does anyone have any idea how to fix the current warnings on MTL and a line of sight on a fix? Right now we are actively training users to ignore the results on MTL and we are blind to possibly WORSE MTL regressions.

I resubmitted the cleanup commits that don't change anything in this new PR:

I'm not sure whether it's a good idea to green-wash our failures

I am sure it's a bad idea to "red-wash" our sparse warnings on MTL, which is what we have been doing for a few weeks now. In other words: if the sparse analysis degrades from "we have warnings" to "it does not even build" then no one will notice. "Red-washed".

This of course on top of training people to ignore MTL warnings in the first place.

We cannot keep CI checks failing for that long. Should be reverted as
soon as the code is fixed.

@lyakh how are the SPARSE MTL fixes in Zephyr coming ?

I believe all sparse warnings are fixed in the Zephyr main branch but upgrading Zephyr is blocked by zephyrproject-rtos/zephyr#53327 (comment)

There was an address space regression and no one noticed:
