From: Changbin Du Date: Tue, 6 Jun 2017 07:56:12 +0000 (+0800) Subject: drm/i915/gvt: Make the MMIO attribute wrappers be inline X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5c6d4c676d0ccba2dcd97e47e1f10321da423e7d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915/gvt: Make the MMIO attribute wrappers be inline Function calls are expensive. I have see obvious overhead call to these wrappers in perf data, especially from the cmd parser side. So make these simple wrappers be inline to kill them all.
