From: Xuan Ding <xuan.d...@intel.com> This patchset introduces a new API rte_vhost_async_dma_unconfigure() to help user to manually free DMA vchannels finished to use.
v7: * Add inflight packets processing. * Fix CI error. v6: * Move DMA unconfiguration to the end due to DMA devices maybe reused after destroy_device(). * Refine the doc to claim the DMA device should not be used in vhost after unconfiguration. v5: * Use mutex instead of spinlock. * Improve code readability. v4: * Rebase to 22.11 rc1. * Fix the usage of 'dma_ref_count' to make sure the specified DMA device is not used by any vhost ports before unconfiguration. v3: * Rebase to latest DPDK. * Refine some descriptions in the doc. * Fix one bug in the vhost example. v2: * Add spinlock protection. * Fix a memory leak issue. * Refine the doc.
