Yes, that was my fault. I also didn't have the selftest on my drm-intel-fixes
build and I confused the build run numbers when checking the
https://intel-gfx-ci.01.org/tree/drm-intel-fixes/index.html?
before sending...
If we have another round next week I will make sure CI runs well before
sending another pull request.
Sorry,
Rodrigo.

I did drop the ball in one way, I see sfr reported it broken this morning
I normally expect stuff coming from Intel has been through their CI,
even their fixes tree generally gets pushed through that system before
I get it, and it usually catches these things.
I might have to push back on intel fixes this late in the day, as
maybe the land on next and cherry-pick to fixes model has made them a
bit lax on how much stuff goes through CI.
I've just drop the whole i915 fixes from the tree and will resend with
it removed.
Dave.

I thought I'd dropped the ball completely. but I see it's a selftest
failure, I must not have selftests built in my config here, I don't do
exhaustive builds randconfig
This has also been built by Intel, but I'm assuming they missed their
selftest bits as well.
I'll revert that and resend.
Sorry for the noise. I'll add self tests to my builds here for future ones.
Dave.

Dave, this doesn't even build. WTF?
In drivers/gpu/drm/i915/gt/selftest_lrc.c, there's a
engine_heartbeat_disable() function that takes two arguments, but the
new "live_timeslice_nopreempt()" gives it only one.
I'd blame a merge problem, since the failure is in new code, but the
problem exists in your top-of-tree, not just my merge.
In fact, it's not even your merge of the i915 tree that is the source
of the problem (although the fact that you clearly didn't _test_ the
end result most definitely is _part_ of the problem!).
Because the problem exists in the commit that introduced that thing:
commit 1f65efb624c4 ("drm/i915/gt: Prevent timeslicing into
unpreemptable requests").
It's garbage, and never compiled.
See here:
git grep -1wh engine_heartbeat_disable 1f65efb62 \
drivers/gpu/drm/i915/gt/selftest_lrc.c
and you'll see how the definition of that function looks like this:
static void engine_heartbeat_disable(struct intel_engine_cs *engine,
unsigned long *saved)
but then in the middle of that grep, you'll find
engine_heartbeat_disable(engine);
WTF?
That commit seems to be a cherry-pick of another commit, and maybe it
worked in that other context (which I don't see), but it sure doesn't
work in the context it was then cherry-picked into.
So people took that thing, and it went through at least two different
people WHO NEVER EVEN BOTHERED TO TEST IF IT BUILDS!
Christ, people.
This is why I absolutely DO NOT WANT TO SEE random rebases or
cherry-picks and then sending the resulting untested crap on to me.
Because it's exactly that: untested crap.
It doesn't matter *how* well you have tested a commit in some original
context: the moment you rebase it (or cherry-pick it, which is just
another form of rebasing), it's a completely new commit in a
completely new environment, and all your old testing is null and void.
Guys, get your act together! I should not be getting these kinds of
shit pull requests days before a release!
And how the hell did this not get any build testing at any point
before asking me to pull?
