This is the proposal, yes. > And from the definition "rte_gpu_free(uint16_t gpu_id, void *ptr)", the > free needs to check whether this memory belong to the GPU or not, so it > also can recognize the memory type, I think. Yes that's the idea behind having a single free function. We could have some metadata in front of the memory chunk. My question is to confirm whether it is a good design or not, and whether it should be driver specific or have a common struct in the lib. Opinions?
