From e1438818b90c5b0d73aae800b12bd6b36aec5142 Mon Sep 17 00:00:00 2001 From: Richard Zhao Date: Thu, 21 Jul 2016 16:51:40 -0700 Subject: gpu: nvgpu: vgpu: add vgpu private data and helper functions Move vgpu private data to a dedicated structure and allocate it at probe time. Also add virt_handle helper function which is used everywhere.
