From 4951dc0178ba144619e9c20ed71f7ff006282bbf Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 17 Jun 2019 11:09:17 +0100 Subject: [PATCH] drm/i915/guc: Reduce verbosity on log overflows If the user is clearing the log buffer too slowly, we overflow. As this is an expected condition, and the driver tries to handle it, reduce the error message down to a notice. Michal mentioned that another cause would be incorrect reset handling, so we don't want to lose the notification entirely.
