From bcc2661e3243fe75b91ec682de01e7cbedfbe7f9 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 18 Jun 2018 08:31:35 +0100 Subject: [PATCH] drm/i915: Only show debug for state changes when banning Since we trigger 10,000s of hangs and resets during selftesting, we emit many, many thousands of lines of useless debug messages. Reduce the frequency by only logging a change in state of a guilty context.
