[igt-dev] [PATCH i-g-t v3 0/4] igt/i915/i915_pm_lpsp enable pm_lpsp for platforms till Gen11 v3

[Anshuman Gupta]

i915_pm_lpsp patch, sending v3 version after adding few
more pacthes to series in order fix CI IGT failures.
1. Check lpsp relevance on non edp panel which.
2. skip edp-panel-fitter test for Gen9 platfrom onwards.

This series has added i915_pm_lpsp subtests to CI fast 
feedback list in order to run cover these subtest on all
affected platforms.

Revision 1 Link:  https://patchwork.freedesktop.org/series/58051/

Anshuman Gupta (4):
  igt/i915/i915_pm_lpsp enable pm_lpsp for platforms till Gen11.
  igt/i915/i915_pm_lpsp check lpsp relevance on non edp panel.
  igt/i915/i915_pm_lpsp skip edp-panel-fitter test.
  DO_NOT_MERGE add i915_pm_lpsp subtests to CI fast feedback list.

[igt-dev] [PATCH i-g-t v3 2/4] igt/i915/i915_pm_lpsp check lpsp relevance on non edp panel.

[Anshuman Gupta]

Earlier on HSW/BDW it was assumed that only eDP panel will act
as lpsp. But that is not true now.
So checking whether a non edp panel can act as lpsp or not.

Please add a code-comment about the purpose of using global variable if 
it is really needed.

This function return type is confusing to me.

This function is updating the power well index and also checking lpsp is 
supported or not which is duplication of existing function supports_lpsp().
As per the above code "update" tag is more suitable than "get".

get_no_lpsp_pw_idx() can be used here to get the power-well index and then use it to create the mask, then global variable can be avoided.

0 or non-zero should be the decision maker. Better not compare with 
"mask" after masking,

supports_lpsp() maybe appropriate here to check igt is required or not.

Re: [igt-dev] ✗ Fi.CI.BAT: failure for igt/i915/i915_pm_lpsp enable pm_lpsp for platforms till Gen11 v3

[Gupta, Anshuman]

Hi Imre ,
Sometimes it has been observed on Gen9 that screens-disabled 
i915_pm_lpsp sub-test failed because power well 2 was not disabled when 
subtest checks its register value. It get disabled slightly later.

https://intel-gfx-ci.01.org/tree/drm-tip/IGTPW_2866/fi-cfl-8109u/igt@i915_pm_lpsp@screens-disabled.html

I checked it locally and found similar behaviour (there were three 
screens connected in my test), below are the log snippet.

[  254.042328] [IGT] i915_pm_lpsp: starting subtest screens-disabled
[  254.042374] [drm:drm_mode_setcrtc] [CRTC:47:pipe A]
[  254.250784] [drm:intel_disable_pipe [i915]] disabling pipe A
[  254.421970] [drm:drm_mode_setcrtc] Returning [CRTC:47:pipe A]
(kernel instrumenting log to indicate drm_mode_setcrtc has returned)
[  254.421990] [drm:drm_mode_setcrtc] [CRTC:65:pipe B]
[  254.423605] [drm:intel_disable_pipe [i915]] disabling pipe B
[  254.437460] [drm:drm_mode_setcrtc] Returning [CRTC:65:pipe B]
[  254.437476] [drm:drm_mode_setcrtc] [CRTC:83:pipe C]
[  254.438526] [drm:intel_disable_pipe [i915]] disabling pipe C
[  254.456603] [drm:drm_mode_setcrtc] Returning [CRTC:83:pipe C]
[  254.464966] [drm:intel_power_well_disable [i915]] disabling power well 2

We can see power well 2 is getting disabled after 8ms of 
drm_mode_setcrtc() ioctl returned, which is sufficient to fail the test.

Do u see any issue with driver behaviour.

If it is expected behaviour from i915 driver then we may need to have
some wait while checking the power well 2 for lpsp.

Thanks ,
Anshuman Gupta.

I think the only reason can be delayed audio disabling. In the above CFL
log I see, which would point to that:

<7> [235.044427] [drm:hsw_audio_codec_disable [i915]] Disable audio codec on pipe A

I haven't managed to track this down in the depths of the HDA runtime PM
code, but I suspect it will result in a - delayed - runtime PM put on
the HDA device which will end up calling
i915_audio_component_put_power(), that drops the PW#2 reference.

You could prove this by dumping debugfs/i915_runtime_pm_status and
i915_power_domain_info when you see PW#2 still on after the IOCTL
returned. You should btw make this debug output part of the test,
perhaps even making a generic helper that we could call in similar
failing scenarios.

If that proves to be the case, the solution is to wait for PW#2 to go
off with some timeout as you suggested.

Thanks for the investigate work!
