[igt-dev] [PATCH i-g-t 1/2] tests/kms_dp_dsc: Read the debugfs only once

[Anusha Srivatsa]

Instead of doing a debugfs_simple_read and then
a debugfs_read(), lets read the debugfs node just once.
We anyway get the suitable return from the following
strstr operation.

For any following subtests, we will be reading only the
contents of the buffer. We can avoid the simple_read
altogether.

[igt-dev] [PATCH i-g-t 2/2] tests/kms_dp_dsc: Add a subtest to force DSC output BPP

[Anusha Srivatsa]

This subtest uses the accepted DSC BPPs and tries to
force a modeset by setting a certain BPP as the output
BPP for a connector.

Not sure if we need to restore the DSC BPP value? What does the kernel code set the force_dsc_bpp value to if
not forced by IGT?

 May be a add a comment here saying these are the supported compressed BPPs on Gen 11

Check the indentation for the code within the igt_subtest_f, it needs one more tab

printf is redundant here, if you want you could have this in igt_debug so its printed only for debug

I don't think we need it. Force_enable_bpp gets set iff we are forcing the dsc. If we are not forcing dsc, and the kernel does DSC because of the resolution restrictions, it computes the compressed bpp according to the calculation that are part of compute_dsc_params() and nothing to do with this value.

Yes I agree. This was for my debugging. I will remove this. I dont think we need it to be in a igt_debug also.

Re: [igt-dev] [PATCH i-g-t 2/2] tests/kms_dp_dsc: Add a subtest to force DSC output BPP

[Srivatsa, Anusha]

The subtest  is still unstable.
The debugfs node - i915_dsc_fec_support is both read and write. We use it to check if sink supports DSC and to force the DSC, Which I think leave it unstable when used for the second time - for the bpp subtest.
IT is either the debugfs node state or maybe the crtc state from the force-dsc subtest that is causing the unstable nature,

Is it a good option to separate the debugfs nodes to read and write specific ?

Manasi, what do you think?

  **FAILURE**

  Serious unknown changes coming with IGTPW_3137_full absolutely need to be
  verified manually.
  
  If you think the reported changes have nothing to do with the changes
  introduced in IGTPW_3137_full, please notify your bug team to allow them
  to document this new failure mode, which will reduce false positives in CI.
