1306a73b19 gpu/cuda: introduce CUDA driver
This is the CUDA implementation of the gpudev library.
Functionalities implemented through CUDA Driver API are:
- Device probe and remove
- Manage device memory allocations
- Register/unregister external CPU memory in the device memory area

e818c4e2bf gpudev: add memory API
In heterogeneous computing system, processing is not only in the CPU.
Some tasks can be delegated to devices working in parallel.
Such workload distribution can be achieved by sharing some memory.

As a first step, the features are focused on memory management.
A function allows to allocate memory inside the device,
or in the main (CPU) memory while making it visible for the device.
This memory may be used to save packets or for synchronization data.

The next step should focus on GPU processing task control.

8b8036a66e gpudev: introduce GPU device class library
In heterogeneous computing system, processing is not only in the CPU.
Some tasks can be delegated to devices working in parallel.

The new library gpudev is for dealing with GPGPU computing devices
from a DPDK application running on the CPU.

The infrastructure is prepared to welcome drivers in drivers/gpu/.
