[igt-dev] [PATCH i-g-t v14 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 changes 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.
v10:Review comment fixup in sata_link_power_management
    lib functions. [Imre]
v11:Add igt_assert_fd(pm_status_fd) in igt_disable_runtime_pm().
    [Imre & Petri]
v12: Refactor is_bios_limits_pc8_plus_residencies() from
     supports_pc8_plus_residencies().
     Changed igt_disable_runtime_pm()return type. [Imre]

[igt-dev] [PATCH i-g-t v14 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 v14 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]
v10:Added AT_LEAST_Gen11 condition instead of IS_ICELAKE in order to
    disable runtime suspend. [Imre]
v11:Added a cleanup_dc_dpms() function. [Imre]

[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.

[igt-dev] [PATCH i-g-t v14 6/6] tests/i915/i915_pm_dc:Skip the DC6 test if BIOS has disabled PC8+

[Anshuman Gupta]

As DC6 requires platform to enter PC8 package C state.
It make sense to skip the DC6 igt-test, if BIOS configuration
has disabled PC8+ package C states.

Re: [igt-dev] [PATCH i-g-t v14 0/6] DC states igt tests patch series

Hey,

This series introduces new undocumented tests:

i915_pm_dc
i915_pm_dc@dc5-dpms
i915_pm_dc@dc5-psr
i915_pm_dc@dc6-dpms
i915_pm_dc@dc6-psr

Can you document them as per the requirement in the [CONTRIBUTING.md]?

[Documentation] has more details on how to do this.

Here are few examples:

https://gitlab.freedesktop.org/drm/igt-gpu-tools/commit/443cc658e1e6b492ee17bf4f4d891029eb7a205d

Thanks in advance!
