Elena Agostini 9b8cae4d99 gpudev: use CPU mapping in communication list ... rte_gpu_mem_cpu_map() exposes a GPU memory area to the CPU. In gpudev communication list this is useful to store the status flag. A communication list status flag allocated on GPU memory and mapped for CPU visibility can be updated by CPU and polled by a GPU workload. The polling operation is more frequent than the CPU update operation. Having the status flag in GPU memory reduces the GPU workload polling latency. If CPU mapping feature is not enabled, status flag resides in CPU memory registered so it's visible from the GPU. To facilitate the interaction with the status flag, this patch provides also the set/get functions for it. Signed-off-by: Elena Agostini <eagostini@nvidia.com>		2022-02-22 20:08:52 +01:00
