From 6e739d924fe9b778fa82396e0e941143f498acb8 Mon Sep 17 00:00:00 2001 From: Alex Waterman Date: Mon, 22 Jan 2018 16:30:53 -0800 Subject: gpu: nvgpu: Userspace POSIX support Add support for compiling nvgpu in a POSIX compliant userspace. This code adds all of the necessary abstraction interfaces (mostly stubbed) to enabled extremely limited and basic functionality in nvgpu. The goal of this code is to facilitate unit testing of the nvgpu common core. By doing this in userspace it is much easier to write tests that rely on very particular states within nvgpu since a user can very precisely control the state of nvgpu.
