From 2958b9013fcbabeeba221161d0712f5259f1e15d Mon Sep 17 00:00:00 2001 From: Zhenyu Wang Date: Fri, 17 Mar 2017 12:11:20 +0800 Subject: [PATCH] drm/i915/gvt: Fix gvt scheduler interval time Fix to correctly assign 1ms for gvt scheduler interval time, as previous code using HZ is pretty broken. And use no delay for start gvt scheduler function.
