Subject: [Qemu-devel] [PATCH 0/5] virtio-net: More configurability and bh handling for tx
Date: Fri, 27 Aug 2010 16:36:59 -0600 [thread overview]
Message-ID: <20100827223659.2696.3589.stgit@s20.home> (raw)
Add the ability to configure the tx_timer timeout and add a bottom
half tx handler that typically shows a nice perf boost over the
time based approach. See last patch for perf details. Make this
the new default when the iothread is enabled. Thanks,
Alex
