[Intel-gfx] [PATCH i-g-t 1/3] i915/gem_exec_schedule: Make gem_exec_schedule understand static priority mapping

[Matthew Brost]

The i915 currently has 2k visible priority levels which are currently
unique. This is changing to statically map these 2k levels into 3
buckets:

low: < 0
mid: 0
high: > 0

Update gem_exec_schedule to understand this. This entails updating
promotion test to use 3 levels that will map into different buckets and
also add bit of delay after releasing a cork beforing completing the
spinners.

Also skip any tests that rely on having more than 3 priority levels.

v2: Add a delay between starting releasing spinner and cork in
promotion, add local define for static mapping engine info

This needs a line about why we add the delay, something like "to give 
time to the i915 scheduler to process the fence release and queue the 
requests" or something.
BTW, any reason not to just add the delay unconditionally in 
unplug_show_queue, instead of only in one test? Other tests might suffer 
from the same problem even if they're not hitting it at the moment.

This needs a line about why we add the delay, something like "to give 
time to the i915 scheduler to process the fence release and queue the 
requests" or something.
BTW, any reason not to just add the delay unconditionally in 
unplug_show_queue, instead of only in one test? Other tests might suffer 
from the same problem even if they're not hitting it at the moment.

Yea, probably a better approach to future proof this as I could see
other sections randomly failing in CI and wasting our time. Will fix
this and subsequent patch too.

[Intel-gfx] [PATCH i-g-t 2/3] i915/gem_ctx_shared: Make gem_ctx_shared understand static priority mapping

[Matthew Brost]

The i915 currently has 2k visible priority levels which are currently
unique. This is changing to statically map these 2k levels into 3
buckets:

low: < 0
mid: 0
high: > 0

Update gem_ctx_shared to understand this. This entails updating
promotion test to use 3 levels that will map into different buckets and
also add bit of delay after releasing a cork beforing completing the
spinners.

v2: Add a delay between starting releasing spinner and cork in
promotion

[Intel-gfx] [PATCH i-g-t 3/3] i915/gem_exec_capture: Update to support GuC based resets

[Matthew Brost]

From: "Signed-off-by: John Harrison" <John.C.Harrison@Intel.com>

When GuC submission is enabled, GuC itself manages hang detection and
recovery. Therefore, any test that relies on being able to trigger an
engine reset in the driver will fail. Full GT resets can still be
triggered by the driver, however in that situation detecting the
specific context that caused a hang is not possible as the driver has
no information about what is actually running on the hardware at any
given time.

So update the test to cause a reset via a the hangcheck mechanism by
submitting a hanging batch and waiting. That way it is guaranteed to
be testing the correct reset code paths for the current platform,
whether that is GuC enabled or not.

[Intel-gfx] [PATCH i-g-t 3/3] i915/gem_exec_capture: Update to support GuC based resets

[Matthew Brost]

From: "Signed-off-by: John Harrison" <John.C.Harrison@Intel.com>

When GuC submission is enabled, GuC itself manages hang detection and
recovery. Therefore, any test that relies on being able to trigger an
engine reset in the driver will fail. Full GT resets can still be
triggered by the driver, however in that situation detecting the
specific context that caused a hang is not possible as the driver has
no information about what is actually running on the hardware at any
given time.

So update the test to cause a reset via a the hangcheck mechanism by
submitting a hanging batch and waiting. That way it is guaranteed to
be testing the correct reset code paths for the current platform,
whether that is GuC enabled or not.

isn't this too big when setting the heartbeat interval to 500 ms and the 
preempt one to 250? 5 secs should be more than enough.

Shouldn't we put these entries back to their original values after the 
test is done?

What does "died" mean here? does it indicate that a reset correctly 
happened? IMO needs a better wording.

This is going to make the test skip on platforms that have full gt reset 
but not engine reset. You can see in the CI results that it is now 
skipping on snb-shards (the change in result is being caught by a 
catch-all fdo, so not reported as a failure).

isn't this too big when setting the heartbeat interval to 500 ms and the 
preempt one to 250? 5 secs should be more than enough.

Shouldn't we put these entries back to their original values after the 
test is done?

What does "died" mean here? does it indicate that a reset correctly 
happened? IMO needs a better wording.
