Macro Definition Documentation

#define RTE_QDMA_BURST_NB_MAX   256

Maximum qdma burst size

If user has configured a Virtual Queue mode, but for some particular VQ user needs an exclusive H/W queue associated (for better performance on that particular VQ), then user can pass this flag while creating the Virtual Queue. A H/W queue will be allocated corresponding to VQ which uses this flag.

Enumeration Type Documentation

anonymous enum

Determines the mode of operation


Allocate a H/W queue per VQ i.e. Exclusive hardware queue for a VQ. This mode will have best performance.


A VQ shall not have an exclusive associated H/W queue. Rather a H/W Queue will be shared by multiple Virtual Queues. This mode will have intermediate data structures to support multi VQ to PQ mappings thus having some performance implications. Note: Even in this mode there is an option to allocate a H/W queue for a VQ. Please see 'RTE_QDMA_VQ_EXCLUSIVE_PQ' flag.
