From d3dce086f76b3de8235bd26fc5d2e14e12ee17f3 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 20 Apr 2020 21:30:40 +0100 Subject: [PATCH] drm/i915/selftests: Show the pstate limits on any failure to reset min We want to see the pstate limits whenever we fail to set the minimum frequency as that may help for debugging.
