[igt-dev] [PATCH i-g-t 0/6] DEBUG DC states igt tests patch series

[Anshuman Gupta]

This is a resubmission of series https://patchwork.freedesktop.org/series/56713/
to collect DC6 igt test failure report from CI Bat test.
This series adds DC state IGT test to CI Fast feedback list.

[igt-dev] [PATCH i-g-t 1/6] lib/igt_pm: igt lib helper routines to support DC5/6 tests

[Anshuman Gupta]

From: Jyoti Yadav <jyoti.r.yadav@intel.com>

This patch does the following chnegs to lib/igt_pm.c

-dmc_loaded() will be used by new test i915_pm_dc.c which will validate
 Display C States. So moving the same to igt_pm library.

-Introduced igt_disable_runtime_pm() in order to disable runtime suspend
 for the function which support dc9.

-Changed the igt_pm_enable_sata_link_power_management() and
 igt_pm_restore_sata_link_power_management() in order to save
 and restore the sata link power policy by an exit handler.

v2: Simplify the comment section.
v3: Remove . from the subject line.
v4: Rebased, resolve conflicts in pm_rpm.c
    Included patch set version change log.
v5: Listing actual change in patch set changelog to make review easier.
v6: igt's lib added support for disabling runtime suspend,
    change in commit log. rebased due to test name pm_rpm changed
    to i915_pm_rpm.
v7: Addressed review comment by saving POWER_DIR values in
    igt_disable_runtime_pm(). [Imre]
v8: Addressed the review comment, igt_pm_enable_sata_link_power_management
    function to restore the original SATA link power policy if things fail
    by using an exit handler. [Imre]
v9: IGT failure fixture in i915_pm_backlight and i915_pm_rpm.

[igt-dev] [PATCH i-g-t 3/6] tests/i915/i915_pm_dc: Added test for DC6 during PSR

[Anshuman Gupta]

From: Jyoti Yadav <jyoti.r.yadav@intel.com>

This patch add subtest to check DC6 entry on PSR for the supported
platforms.

v2: Rename the subtest with more meaningful name.
v3: Rebased.
v4: Rebased, to fix compilation error in psr_enable().
    Addressed review comment by fixing typo in comment description
    of DC6 PSR subtest.
v5: Addressed the review comment by removing redundant read_dc_counter(),
    clubbed cleanup() function in test_dc_state_psr() suggested by Imre.
    Listing actual change in patch set changelog to make review easier.
v6: Rebased due to test name pm_dc changed to i915_pm_dc, aligning to
    other PM tests.

[igt-dev] [PATCH i-g-t 4/6] tests/i915/i915_pm_dc: Added test for DC5 during DPMS

[Anshuman Gupta]

From: Jyoti Yadav <jyoti.r.yadav@intel.com>

Added new subtest for DC5 entry during DPMS on/off cycle.
During DPMS on/off cycle DC5 counter is incremented.

v2: Rename the subtest with meaningful name.
v3: Rebased.
v4: Addressed review comments by removing leftover code
    cleanup().
v5: Addressed the review comment by removing redundant
    read_dc_counter() suggested by Imre.
    Listing actual change in patch set changelog to make review easier.
v6: Three way patch applied, no functional change.
v7: Disabling runtime suspend for the platform which support, DC9.
    rebased due to test name pm_dc changed to i915_pm_dc, aligning to
    other PM tests.
v8: Introduced setup_dc_dpms() in order to disable runtime pm, restoring
    POWER_DIR values to its original and enabling runtime pm  for other
    followed sub-tests.
v9: Check DC5 counter value after DPMS off, broke the dpms_on_off
    function to dpms_on and dpms_off. [Imre]

[igt-dev] [PATCH i-g-t 5/6] tests/i915/i915_pm_dc: Added test for DC6 during DPMS

[Anshuman Gupta]

From: Jyoti Yadav <jyoti.r.yadav@intel.com>

Added new subtest for DC6 entry during DPMS on/off cycle.
During DPMS on/off cycle DC6 counter is incremented.

v2: Renamed the subtest name.
v3: Rebased.
v4: Addressed review comment by replacing igt_display_init() to
    igt_display_require(), changes got done in patch set 2.
v5: Addressed the review comment by removing redundant read_dc_counter()
    suggested by Imre.
    Listing actual change in patch set changelog to make review easier.
v6: Rebased due to test name pm_dc changed to i915_pm_dc, aligning to
    other PM tests.
v7: Introduced setup_dc_dpms() inorder to disable i915 runtime PM for
    the platform supports DC9.

Re: [igt-dev] ✓ Fi.CI.BAT: success for DEBUG DC states igt tests patch series

[Gupta, Anshuman]

Hi Imre ,

It has been observed that CI platform which has limited the package c 
state below PC8 from BIOS are failing to reach DC6 state.

Same behavior has been observed on local DUT. DC6 igt tests were passing 
when package C state were limited to PC10, when we limited it to PC7, 
DC6 igt test started failing.
if this behavior is correct (will confirm from H/W folks), we should 
skip the DC6 igt test if package C state limited below PC8.


DC6 IGT test summary report :

As of now DC6 igt test are only passing on fi-icl-dsi, fi-icl-y, 
fi-cml-u platform.

DC6 igt test are failing on fi-whl-u and fi-kbl-r despite reaching to 
PC8 (this need to be addressed separately).

https://intel-gfx-ci.01.org/tree/drm-tip/IGTPW_3144/fi-whl-u/igt@i915_pm_dc@dc6-dpms.html

https://intel-gfx-ci.01.org/tree/drm-tip/IGTPW_3144/fi-kbl-r/igt@i915_pm_dc@dc6-dpms.html

Below platform has failed DC6 state because these platform failed to 
reach PC8.

fi-cml-u2
fi-cfl-8109u
fi-kbl-7567u
fi-skl-6600u

Rest all DC6 failures are due to that fact that BIOS has limited the 
package c state (these all platform are skipping the pc8 residencies IGT 
test).

Thanks ,
Anshuman Gupta.

[igt-dev] [PATCH i-g-t 3/6] tests/i915/i915_pm_dc: Added test for DC6 during PSR

[Anshuman Gupta]

From: Jyoti Yadav <jyoti.r.yadav@intel.com>

This patch add subtest to check DC6 entry on PSR for the supported

    Addressed review comment by fixing typo in comment description
    of DC6 PSR subtest.
v5: Addressed the review comment by removing redundant read_dc_counter(),
    clubbed cleanup() function in test_dc_state_psr() suggested by Imre.
    Listing actual change in patch set changelog to make review easier.
v6: Rebased due to test name pm_dc changed to i915_pm_dc, aligning to
    other PM tests.
