[igt-dev] [PATCH v1 1/4] tests/kms_display_modes: Add negative test for extended display

[Mohammed Thasleem]

Added negative test to validte ENOSPC when two 2k-4k or 4k-4k
moniters connected through MST.
This test added to provide bandwidth issue in MST config.

Example:
  When two monitors connected through MST, the second monitor
  also tries to use the same mode. So two such modes may not
  fit into the link bandwidth. So, iterate through connected
  outputs & modes and find a invalid combination.

v2: Rebased on tip.
v3: -Code cleanup and updated description.
    -Free path_blob before call return. (Kamil)
v4: Updated code formatting and function description. (Jeevan)
v5: Updated commit description and minor changes.
v6: Added bigjoiner check and updated comments. (Bhanu)

[igt-dev] [PATCH v1 3/4] tests/kms_display_modes: Fixed mode selection for extended mode tests

[Mohammed Thasleem]

Added check on DP-MST and 4k panels when two moniters connected
through MST.
This will find the connector mode combo that fits into the
bandwidth when more than one monitor is connected.

Example:
  When two monitors connected through MST, the second monitor
  also tries to use the same mode. So two such modes may not
  fit into the link bandwidth. So, iterate through connected
  outputs & modes and find a combination of modes those fit
  into the link BW.

v2: -Updated commit msg and description. (Bhanu)
    -Renamed restart with retry. (Bhanu)
    -Moved igt_pipe_crc_new before retry. (Bhanu)
    -Removed unrelated changes and new line. (Bhanu)
    -Minor changes.
v3: Updated discription and added EINVAL check.
v4: Removed EINVAL and ENOSPC checks.
    Added check for DP-MST and 4k panels.
    Updated discription.
v5: Defined 4k display modes globally.
v6: -Removed if loop checks.
    -Added igt override to avoid dp mst bw failure.
