Hmm, I'm still not sure I understand this. Do you mean rebuilding the
tests out-of-tree and then running them against a newer/older libdrm
version?

Because from my understanding the tests are always build together with
libdrm anyway. Or am I misunderstanding here something?

Maybe a dumb question, but what would be the right thing to do in may case.

Define my own MY_XZY_EVENT_CONTEXT_VERSION and use these?

With best wishes,
Tobias
