[igt-dev] [PATCH i-g-t 0/2] Integrate igt_spin_new with Xe.

[igt-dev] [PATCH i-g-t 0/2] Integrate igt_spin_new with Xe.

[sai.gowtham.ch]

From: Sai Gowtham Ch <sai.gowtham.ch@intel.com>

Extending the spin_create implementation and allocator handle support in xe,
where it submits dummy work loads to engine. This Implementation is wrapped
around vm_bind and unbind as we are supposed to do it manually for xe.

  lib/xe/xe_spin: Integrate igt_spin_new with Xe.
  tests/xe/xe_spin_batch: Add new test to exercise igt_spin_new for xe.

I think you should support two variants of executing spinners:

1. hwe != NULL (in this case engine must be 0):
   if (!vm) -> create vm;
   create engine for vm according to hwe

2. engine != 0, vm must be vm on top of which engine was created
   hwe must be NULL in this case
   see Dominik answer about passing engine+vm in:
   https://patchwork.freedesktop.org/patch/539173/?series=118227&rev=2

And add support ALL_ENGINES flag (then iterate over all hw engines
like Bhanu suggested). And track engine ownership - if caller
is the engine/vm owner use it but don't destroy, if spinner code
is creating engine you may freely destroy it in spinner free path().

Do we have Driver support for ALL_ENGINES flag ?? 

I think what Bhanu asking for is as kms tests  doesn’t need hwe, We have to pass hwe from the xe_spin_create it self. 
In that case we can add a support in xe_spin_create where hwe = 0 and engine = 0 ( Note  this is only for kms tests) .

I feel ALL_ENGINES support can be added later, Once kms tests are unblocked.

Regarding igt_spin_free, I've already added support not to destroy vm and engines if they are passed from the igt test. Can you have a look at igt_spin_free (Verified it's working fine for me).

Yes, KMS tests are not supposed to pass hwe or engines.

I just realised xe_spin_create with engine_id = 0 will not work, However is there a way to create engine without hwe ?

You shouldn't imo destroy engine/vm inside igt_spin_free(). Caller
is the owner and they should stay intact.

If instead .engine you'll pass .hwe you may create engine on top
of vm (if passed, if not create new one) and destroy in igt_spin_free().

Resume: track the ownershipping.

Test both variants: with engine/vm created in the test and passed
via .engine + .vm field and with passing .hwe only. Add also
support for ALL_ENGINES flag.

I'm handling this in igt_spin_free itself, if you look at the igt_spin_free code that I've sent for review I'm checking if it's passed from the igt test or 
Is it created inside the xe_spin_create, I'm not destroying engine and vm when it's passed from igt test.

I think spin-batch already covers that, it passes both engine and vm to igt_spin_new which are created in the test.
And spin-basic passes only .hwe to igt_spin_new.

So in this case you should destroy it in the test, otherwise it will
dangle when test is done.

[igt-dev] [PATCH i-g-t 0/2] Integrate igt_spin_new with Xe

[sai.gowtham.ch]

From: Sai Gowtham Ch <sai.gowtham.ch@intel.com>

Extending the spin_create implementation and allocator handle support in xe,
where it submits dummy work loads to engine. This Implementation is wrapped
around vm_bind and unbind as we are supposed to do it manually for xe.
