From: Chris Wilson Date: Mon, 17 Jun 2019 10:09:17 +0000 (+0100) Subject: drm/i915/guc: Reduce verbosity on log overflows X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4951dc0178ba144619e9c20ed71f7ff006282bbf;p=openwrt%2Fstaging%2Fblogic.git 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.
