> Subject: [dpdk-dev] [PATCH] gpudev: introduce memory API
> 
> From: Elena Agostini <eagostini at nvidia.com>
> 
> 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.
