[igt-dev] [PATCH i-g-t] tests/kms_flip : skip subtest bo-too-big

[Pillai, Aurabindo]

[AMD Official Use Only]

Hi Mark,


Both bo-too-big and bo-too-big-interruptible shall be skipped with this patch. The other location where TEST_BO_TOOBIG is mentioned is in the same function.

There is also another place where TEST_BO_TOOBIG is used, should we
skip this one as well or it's only this part?
