From b1cff585784edf2ab03edb63376a7543a9c50644 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Thu, 22 Oct 2020 22:08:14 +0100 Subject: [PATCH] drm/i915/selftests: Skip RPS tests on Ironlake (only IPS) MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Since Ironlake uses intel_ips.ko for its dynamic frequency adjustment, we do not have direct control over the frequency management so such tests are defunct. Similarly, we can't check the gen6+ RPS registers on Ironlake. Hopefully this catches all the invalid tests now that Ironlake has rejoined the dynamic GPU frequency club. There is an opportunity for the reader to add tests to exercise MEMINTRSTS and co.
