We have used vgem and sw_fence in the past to be able to have very
controlled timelines. This allows us to write generic testcases. The
current igt tests for syncobj are neither i915 nor amdgpu specific.
You might still want to have an amgpu test on top, we do have some i915
tests for the i915 execbuf integration of syncobj of course. But that's a
fairly minor part of the syncobj api.
For contributing to igt, see https://gitlab.freedesktop.org/drm/igt-gpu-tools/blob/master/CONTRIBUTING.md

Looked reasonable, the detailed questions need userspace (and so probably
better answered by someone who has mesa/vk/gl clue). I can help review
corner cases of the uapi, but that's much easier to do once we have
test-cases to exercise them all. See existing igts for an idea of what
exhaustive testing of uapi corner cases looks like.
