From 1e9f1392795e63f20d109b2ee6d44a7ffc99b7ab Mon Sep 17 00:00:00 2001 From: Xiangliang Yu Date: Thu, 12 Jan 2017 14:53:08 +0800 Subject: drm/amdgpu/virt: add high level interfaces for virt MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add high level interfaces that is not relate to specific asic. So asic files just need to implement the interfaces to support virtualization.
