[PATCH i-g-t 0/2] check modparam before enabling psr mode

[PATCH i-g-t 0/2] check modparam before enabling psr mode

[Kunal Joshi]

with i915.enable_psr modparam, one can enable required psr version

i915.enable_psr = 0 PSR_1 and PSR_2 tests should skip
i915.enable_psr = 1 PSR_1 tests should run but PSR_2 tests should skip
i915.enable_psr = 2 PSR_1 and PSR_2 tests should run

fix test to check modparam before enabling through psr_debug debugfs

IMHO, Please don't assert here. Instead, allow the user to decide if 
modparam "enable_psr" is not available.

IMHO, Please don't assert here. Instead, allow the user to decide if modparam "enable_psr" is not available.

- Bhanu

I think it's fine to assert since we expect enable_psr to be present,
since the caller may not handle this, one less thing to worry 😊

I can see this is done similarly at many place 
example :- intel_pipe_output_combo_valid

I am just thinking about the scenario, where the panel is capable of PSR 
but failed to read "enable_psr".

As enable_psr is already present, I guess, we are OK with this change.

Then we must review & fix them if required :-)

[PATCH i-g-t 2/2] tests/intel/kms_psr: enable given psr mode only after checking enable_psr modparam

[Kunal Joshi]

don't enable a psr mode with psr_debug debugfs, instead check what's
the modparam value for i915_enable_psr

This change will cause the skips in dynamic subtests. Skipping the 
dynamic subtest is not recommended, instead don't run the test.

So the proper place for this check would be before calling the 
igt_dynamic().

This change will cause the skips in dynamic subtests. Skipping the dynamic subtest is not recommended, instead don't run the test.

So the proper place for this check would be before calling the igt_dynamic().

- Bhanu

I would advise we change this approach and skip dynamic test
instead of using continue and potentially hiding an issue.

[PATCH i-g-t 0/2] check modparam before enabling psr mode

[Kunal Joshi]

with i915.enable_psr modparam, one can enable required psr version

i915.enable_psr = 0 PSR_1 and PSR_2 tests should skip
i915.enable_psr = 1 PSR_1 tests should run but PSR_2 tests should skip
i915.enable_psr = 2 PSR_1 and PSR_2 tests should run

fix test to check modparam before enabling through psr_debug debugfs

Kunal Joshi (2):
  lib/igt_psr: add helper to check of given psr mode can be enabled
  tests/intel/kms_psr: enable given psr mode only after checking
    enable_psr modparam

[PATCH i-g-t 2/2] tests/intel/kms_psr: enable given psr mode only after checking enable_psr modparam

[Kunal Joshi]

don't enable a psr mode with psr_debug debugfs, instead check what's
the modparam value for i915_enable_psr
