[igt-dev] [PATCH i-g-t v4 0/6] lpsp platform agnostic support

[igt-dev] [PATCH i-g-t v4 0/6] lpsp platform agnostic support

[Anshuman Gupta]

This series adds lpsp igt val platform agnostic support.
This has been a big gap on igt validation side in order to 
validate low power single pipe use cases.

v4 has added new pacthes to patchset to remove the unnecessary
subtests.

This should be test with i915 lpsp support, which adds
i915_lpsp_info debugfs.

Anshuman Gupta (6):
  tests/i915_pm_lpsp: rename non-edp test to non-edp-lpsp
  tests/i915_pm_lpsp: Nuke the panel-fitter test.

[igt-dev] [PATCH i-g-t v4 1/6] tests/i915_pm_lpsp: rename non-edp test to non-edp-lpsp

[Anshuman Gupta]

HASWELL/BROADWELL tests non-edp panel for non-lpsp
i.e. tests HSW_GLOBAL power well should be enabled.
There is ROI to check whethter power well enabled,
if power well is not enabled then we would see all other
types of display issue in other igt test.

It make sense to rename the non-edp test to non-edp-lpsp
as on gen9+ non-edp panel can also drive lpsp.

[igt-dev] [PATCH i-g-t v4 2/6] tests/i915_pm_lpsp: Nuke the panel-fitter test.

[Anshuman Gupta]

panel-fitter subtest is only applicable to HASWELL/BROADWELL.
It just test non-lpsp(lpsp disabled) when panel fitter is
enforced by std 1024x768 mode.
There is no ROI to test non-lpsp kind of thing,
If HSW_GLOBAL power well is not enabled we would see
other display issues in other display tests.

Gen9+ platform has display scaling feature in built per
pipe, as lpsp is all about low power single pipe (PIPE A)
usage, gen9+ platforms also don't require panel-fitter subtest.
This should save some CI cycles.

[igt-dev] [PATCH i-g-t v4 3/6] lib/igt_pm: Add lib func to get lpsp capability

[Anshuman Gupta]

This lib function evaluate the lpsp capability from
the connector specific debugfs attribute i915_lpsp_info.

v2:
- changed the lib function prefix igt_output_is_lpsp_capable
  to i915_output_is_lpsp_capable. [Martin]
v3:
- early return for the connector which doesn't support
  lpsp on any platform.

[igt-dev] [PATCH i-g-t v4 4/6] tests/i915_pm_lpsp: lpsp platform agnostic support

[Anshuman Gupta]

Current implementation of lpsp igt test, assumed that every non-edp
panel isn't a lpsp panel but it is not true on TGL anymore,
any HDMI/DP/DSI panel connected on pipe A and connected to PORT_{A,B,C}
can drive LPSP.
Even on older Gen9 platform a DP panel can drive lpsp on Port A.
This requires complete design change in current lpsp igt for a platform
agnostic support.

The new igt approach is relies on connector specific debugfs
attribute i915_lpsp_info, which exposes whether an output is capable
of driving lpsp and whether lpsp is enabled.

v2:
- CI failures fixup.
v3:
- removed unloading of snd_modules. [Martin]
v4:
- Don't test non-lpsp(if lpsp disabled), no ROI to test that.
- nuke panel-fitter test.

[igt-dev] [PATCH i-g-t v4 5/6] tests/i915_pm_lpsp: screens-disabled subtest use igt_wait

[Anshuman Gupta]

When all screens are disabled, it takes some time to release
eDP/DP AUX IO power domain ref count. Also, delayed audio codec
disabling takes time to release AUDIO power domain ref-count,
using igt_wait to check lpsp after disabling all screens.

[igt-dev] [PATCH i-g-t v4 6/6] tests/i915_pm_rpm: lpsp/non-lpsp screen mode_set_data

[Anshuman Gupta]

Initialize the mode set params for lpsp/non-lpsp screen
based upon their output lpsp capability instead
of edp/non-edp output type.

v2:
- CI failures fixup.
v3:
- changes according to lib function igt_output_is_lpsp_capable
  prefix chnaged to i915_output_is_lpsp_capable.
