Subject: [dpdk-dev] [PATCH v7 0/5] vhost: handle memory hotplug for async vhost
Date: Thu, 22 Jul 2021 04:09:02 +0000	[thread overview]
Message-ID: <20210722040907.20468-1-cheng1.jiang@intel.com> (raw)
In-Reply-To: <20210602042802.31943-1-cheng1.jiang@intel.com>

When the guest memory is hotplugged, the vhost application which
enables DMA acceleration must stop DMA transfers before the vhost
re-maps the guest memory.

This patch set is to provide an unsafe API to drain inflight pkts
which are submitted to DMA engine in vhost async data path, and
notify the vhost application of stopping DMA transfers. And enable it
in vhost example.

v7:
 * rebased on the latest codes
 * improved commit log
v6:
 * removed unnecessary args for the new API
 * improved variable names and function names
 * added enable notification in set_mem_table
 * fixed vhost example queue clear process
v5:
 * added fixes in 'vhost: fix async vhost ops return type'
 * improved git log, variable names and logs
v4:
 * rebased on the latest codes
v3:
 * added a patch to fix async ops return type
 * fixed async ops fail handler
 * updated the doc
v2:
 * changed the patch structure

  vhost: add unsafe API to clear packets in async vhost
  examples/vhost: handle memory hotplug for async vhost
  doc: update doc for queue clear API in vhost lib
