Subject: [dpdk-dev] [PATCH v2 00/10] net/virtio: fix queue reconfigure issue
Date: Sat, 5 Nov 2016 17:40:55 +0800 [thread overview]
Message-ID: <1478338865-26126-1-git-send-email-yuanhan.liu@linux.intel.com> (raw)
In-Reply-To: <1478189400-14606-1-git-send-email-yuanhan.liu@linux.intel.com>
This patchset fixes few issues related to virtio queue reconfigure:
increase or shrink the queue number. The major issue and the reason
behind is described with length details in patch 4 "net/virtio: allocate
queue at init stage".
Those bugs can not be fixed by few lines of code, it's because the
current driver init logic is quite wrong, that I need change quite many
places to make it right. Meanwhile, I have already done my best to keep
the changes being as minimal as possible, so that we could have fewer
changes to break something else; also, it's would be easier for review.
v2: - fix two more minor issues regarding to queue enabling; see patch 9
and 10.
- refined commit log a bit.
Thanks.
