From ad4b1a45e2baf15db0613137635dde8ac496300a Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Thu, 13 Dec 2018 16:39:10 +0100 Subject: lib/igt_kms: Add helpers to count and iterate planes from output With helpers to count and iterate among planes of a given type from the pipe in place, we can use them with the current pipe for the output to make it possible for tests to use them (the pipe struct is not currently easily exposed to tests and exposing it adds unnecessary complexity).
