Subject: [PATCH v7 0/2] vhost: introduce DMA vchannel unconfiguration
Date: Thu, 20 Oct 2022 09:11:01 +0000 [thread overview]
Message-ID: <20221020091103.43422-1-xuan.ding@intel.com> (raw)
In-Reply-To: <20220814140442.82525-1-xuan.ding@intel.com>
From: Xuan Ding <xuan.ding@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.
