[PATCH v2 0/2] Fix for two GuC issues

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Fix for a deadlock issue between the GuC busyness stats worker and GT
resets. Also fix kernel contexts not getting the correct scheduling
priority at start of day.

v2: Rename existing uses of _trylock rather than adding a _noretry
version. Also improve the comment a bit.

[PATCH v2 1/2] drm/i915/guc: Properly initialise kernel contexts

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

If a context has already been registered prior to first submission
then context init code was not being called. The noticeable effect of
that was the scheduling priority was left at zero (meaning super high
priority) instead of being set to normal. This would occur with
kernel contexts at start of day as they are manually pinned up front
rather than on first submission. So add a call to initialise those
when they are pinned.

Does this need a fixes tag? on one side, we were leaving the priority to 
the wrong value, but on the other there were no actual consequences.

I think that's the point. There was no actual issue, it's just a 
theoretical problem. So there is nothing to be gained by pushing this as 
a fix. It it seems like it would be a lot of unnecessary effort to push 
it all the way back to 5.17.

[PATCH v2 2/2] drm/i915/guc: Don't deadlock busyness stats vs reset

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The engine busyness stats has a worker function to do things like
64bit extend the 32bit hardware counters. The GuC's reset prepare
function flushes out this worker function to ensure no corruption
happens during the reset. Unforunately, the worker function has an
infinite wait for active resets to finish before doing its work. Thus
a deadlock would occur if the worker function had actually started
just as the reset starts.

The function being used to lock the reset-in-progress mutex is called
intel_gt_reset_trylock(). However, as noted it does not follow
standard 'trylock' conventions and exit if already locked. So rename
the current _trylock function to intel_gt_reset_lock_interruptible(),
which is the behaviour it actually provides. In addition, add a new
implementation of _trylock and call that from the busyness stats
worker instead.

v2: Rename existing trylock to interruptible rather than trying to
preserve the existing (confusing) naming scheme (review comments from
Tvrtko).

LGTM but I don't remember fully how ping worker and reset interact so 
I'll let Umesh r-b. Like is it okay to skip the ping or we'd need to 
re-schedule it ASAP due wrap issues? Maybe reset makes that pointless, I 
don't remember.

The reset is cancelling the worker anyway. And it will then be 
rescheduled once the reset is done. And the ping time is defined as 
1/8th the wrap time (being approx 223 seconds on current platforms). So 
as long as the reset doesn't take longer than about 200s, there is no 
issue. And if the reset did take longer than that then we have bigger 
issues than the busyness stats (which can't actually be counting anyway 
because nothing is running if the GT is in reset) being slightly off.

In addition to canceling the ping worker, __reset_guc_busyness_stats is 
performing the same activities that the ping-worker would do if it were

I have no idea what I supposed to make of this. Clicking the 'FAIL' link 
just produces an 'Access Denied' XML file, it's not even HTML.

Also, this patch has no functional change for any non GuC submission 
platform and ICL is not GuC submission enabled. So assuming this issue 
is not related.

As above, this is a GuC only change so will not affect SKL or ICL.
