[igt-dev] [i-g-t V4 38/52] tests/i915/kms_big_joiner: Negative tests for Bigjoiner

Bhanuprakash Modem
2022-09-21T16:00:31Z

Add negative tests to validate Bigjoiner or 8K mode.

Example:
* Pipe-D wont support a mode > 5K
* To use 8K mode on a pipe then consecutive pipe must be available & free.

Kernel should reject the commit/modeset if above conditions won't met.

V2:
- Fix redundant negative tests
