The new library gpudev is for dealing with GPU from a DPDK application
in a vendor-agnostic way.

As a first step, the features are focused on memory management.
A function allows to allocate memory inside the GPU,
while another one allows to use main (CPU) memory from the GPU.

The infrastructure is prepared to welcome drivers in drivers/gpu/
as the upcoming NVIDIA one, implementing the gpudev API.
Other additions planned for next revisions:
  - C implementation file
  - guide documentation
  - unit tests
  - integration in testpmd to enable Rx/Tx to/from GPU memory.

The next step should focus on GPU processing task control.

Is this patch for 'L2FWD-NV Workload on GPU' on P26 ?

Yes this is the same project: use GPU in DPDK workload.
