From d9a0b0f884e910987af1ca14136bdab9a8f19cab Mon Sep 17 00:00:00 2001 From: Aurabindo Pillai Date: Mon, 4 Oct 2021 15:28:03 -0400 Subject: tests/kms_bw: Add generic commit test for bandwidth validation Add linear tiling mode tests Changes in v5: Changes to test_init so that test invalid pipes are not used if certain pipes dont exist in chronological order Added comment explaining use of explicit for loop over IGT_MAX_PIPES instead of for_each_pipe_static() Changes in v4: Removed igt_skip_on_simulation from main function. Changes in v3: This version implements array of test modes in igt_main, global IGT_MAX_PIPE and other comments from Mark. Changes in v2: Test added as generic IGT.
