[igt-dev] [PATCH i-g-t] tests/psr: Skip if PSR cannot be enabled for the current mode.

[igt-dev] [PATCH i-g-t] tests/psr: Skip if PSR cannot be enabled for the current mode.

[Dhinakaran Pandiyan]

PSR tests on ICL fail waiting for PSR to become active, whereas the
driver does not enable it on the HW due to unmet timing requirements
[  482.485873] [drm:intel_dp_compute_config [i915]] PSR condition failed: PSR setup time (330 us) too long
We should probably bring back the kernel patch that programmed an alternate
mode, but skip tests for now.

For both of these, we don't even need to read debugfs if data->with_psr_disabled.

If you are reading the debugfs frequently, cache the debugfs dir

data->debugfs = igt_debugfs_dir(data->drm_fd);

Then use igt_sysfs_read(data->debugfs, "i915_edp_psr_status", buf, sizeof(buf));

Is there any delay before PSR is enabled?

We really should adopt yaml (mild background rant).

Correct, will move the check ahead.

Didn't know we had a function to do this, thanks.

Enabled should be set when modeset completes, so we shouldn't be
needing a delay. Not too sure how a non-blocking modeset would behave.

As a standard debugfs format?

Yeah, still human readable yet parseable and gets us away from our ad
hoc parsers/interpreters. I guess what I really want is an introspection
framework. I can but dream.

At the moment, I am just trying to remind myself that the next time I do
a debugfs file, it should talk yaml and igt should complain if it is
malformed -- as well as provide a framework for convenient
interpretation.

This could hide bugs in gen <= 9.

Why not just require that gen is <= 9 or 10(if it is working in CNL)?
and leave a TODO.

This isn't related to gen, it just so happens that the panel on the ICL
machine has a setup time that cannot be met.

But, the patch does hide bugs if the driver does not enable PSR when it
should have.
