I would propose these two apis. /* * fetches an event from the driver event queue. NULL means that queue * is empty. Can sleep if needed. The memory for cxl_event is allocated * by module being called. Hence it can be potentially be larger then * sizeof(struct cxl_event). Multiple calls to this should return same * pointer untill ack_event is called. */ struct cxl_event * fetch_event(struct cxl_context * ctx); /* * Returns and acknowledge the struct cxl_event * back to the driver * which can then free it or maybe put it back in a kmem_cache. This * should be called once we have completely returned the current * struct cxl_event from the readcall */ void ack_event(struct cxl_context * ctx, struct cxl_event *);
How would you implement polling on those APIs? How would you implement afu_read? There are several sources of events. Fred _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
