[igt-dev] [PATCH i-g-t v10 0/5] DC states igt tests patch series v10

[Anshuman Gupta]

This patch series adds new tests to validate Display C states.
DC states like DC5 and DC6 are validated during PSR entry/exit and during DPMS on/off cycle.

Sending new revision of patch series after addressing review comments and other relevant changes.

1. Changing the name of test from "pm_dc" to "i915_pm_dc" alinged to other PM tests.
2. Changing the DC5/6 counter check timeout from 1 sec to 3 sec,
   as in case of PSR  it requires more than 2 second to disable DC
   power wells after vblank event.
3. Changed the test name from tests/pm_dc to tests tests/i915/i915_pm_dc in
   name of individual patch.
4. Addressed the review comment by saving POWER_DIR values in igt_disable_runtime_pm().
5. CI fixures for dc5-dpms failure.
   Checking DC5 counter value after DPMS off, broke the dpms_on_off
   function to dpms_on and dpms_off.
6. Used igt_pm_enable_sata_link_power_management() function in order to use
   min_power policy for SATA.
