From: Xiong Zhang Date: Mon, 22 May 2017 21:38:08 +0000 (+0800) Subject: drm/i915/gvt: Change flood gvt dmesg into trace X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7fb6a7d65292a524256ed6e2d0e94071b0c53936;p=openwrt%2Fstaging%2Fblogic.git drm/i915/gvt: Change flood gvt dmesg into trace Currently gvt dmesg is so heavy at drm.debug=0x2 that guest and host almost couldn't run on xengt. This patch transfer these repeated messages into trace, so dmesg is light at drm.debug=0x2, and user could get the target message through trace event and trace filter.
