I think reducing workload on cores would help having a better power management. Having a unified interrupt support is the first step for a better adoption from applications. VFIO / igb_uio / others do not aggregate / demux interrupts in the same way, meaning that for a single application to have a NAPI-like behavior requires significant device-specific code, dependent upon the current IO driver used. Instead of proposing only rxq-interrupt, a possible evolution could be to propose NAPI-like bursts, that would abstract away the rx-interrupt handling and allow all PMDs to behave similarly. Is it a bug? looks like the open discussion. |
