these tests can fail at src/vulkan/wsi/wsi_common_queue.h:132
They have been disabled in the CI.
Jason suggested that Vulkan's lack of support for vblank_mode resulted in X putting the display to sleep (and limiting fps to 1). This would stall tests for long periods of time.
After executing `xset dpms force on` for the X session, hangs seem to have ceased.
However, incremental_present tests intermittently fail on KBL. Jason suggested modesetting vs sna as a possible difference for the default kbl config.
Xorg's log indicates modesetting/dri2 for skl and kbl platforms. skl passes incremental present reliably.
These tests are disabled for kbl only.
