* gpu: nvgpu: posix: move the posix dir to osAlex Waterman2018-08-17
| | | | | | | | | | | Since the posix code is supporting a particular OS this code should belong under os/ not common/.

* gpu: nvgpu: Implement common nvgpu_mem_rd* functionsTerje Bergstrom2018-07-02
| | | | | | | | | | | | | | | | | nvgpu_mem_rd*() functions were implemented per OS. They also used nvgpu_pramin_access_batched() and implemented a big portion of logic for using PRAMIN in OS specific code. Make the implementation for the functions generic. Move all PRAMIN logic to PRAMIN and simplify the interface provided by PRAMIN.

* gpu: nvgpu: Userspace POSIX supportAlex Waterman2018-05-07
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.
