[igt-dev] [PATCH i-g-t 1/2] lib: Require drmModeResources()

[Chris Wilson]

If modesetting is not supported, the drmModeGetResources() call will
fail with -EINVAL (or -ENOTSUPP). As no displays are connected, skip.

[igt-dev] [PATCH i-g-t 2/2] lib: Skip drmModeReources()

[Chris Wilson]

An alternative to requiring the display is to mark the attached display
as empty (no available CRTC, no outputs) and let the tests skip if they
required any output. This allows the binary to open the display once in
its global fixture, even if it doesn't use the display in every subtest
and so avoid skipping the subtests that didn't require the display.

This one sounds better than the second patch to me.
I just sent this patch together with other patch skiping the tests not
handled by this one.
