Hi Dan,
Suspecting that these were meant for the intel-gfx list, although I doubt people will object seeing them here :-)

Add tests for KMS atomic modesetting, to exercise the basic interface and test failure/corner cases. Should ensure coherency between the legacy and atomic interfaces.
v2: New patch. v3: Disable connector checking for now, as it was causing GPU hangs on newer kernels. v4: Rebase. v5: Use do_ioctl or do_ioctl_err consistently. Use igt_assert_*() helper macros rather than igt_assert() directly. Move assertions into helper/check functions. Define atomic commit helper. v6: Use do_ioctl_err, and define macros to move errors to actual callsite, rather than helper functions. v7: Fix RELAX_MODE thinko and refresh CRTC state in find_crtc.

Afaics you're not using anything intel specific here. I'd suspect one wants to bump (add) the libdrm version, this way igt can remove a lot of the local duplication.

... like the above but we still need the cursor bits :-(

Worth adding a note where these MAX values come from - intel specific, educated guess, etc ?

Perhaps add a reference to the bugzilla ticket/discussion thread ?
As it goes - just my 2c, fwiw.
