[igt-dev] [PATCH v3 0/2] 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.

[igt-dev] [PATCH v3 1/2] 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)

Btw could you decipher here MST like:

MST (Multi-Stream Transport).

-------------------- ^
It is unclear, I guess the bw is limited so maybe write here
what it is ? Like:

Bandwidth of MST is limited to two 2k monitors.

Please correct my guess in above statement (maybe it is
even more limited and max is two 1k ?)
What is max bw for MST connection ? Your code tests for 4k-4k ?

You are not checking >= 2k on mst[0] here.

[igt-dev] [PATCH v3 2/2] lib/igt_kms: Check for other modes to fit on bw when ENOSPC failure

[Mohammed Thasleem]

It check other then ENOSPC failure and if its ENOSPC then check all
active outputs modes to fit possible bw and return false if not found
any suitable bw.

v2: Check for other then ENOSPC failure. (Bhanu)
v3: Updated commit message.
