Subject: [Qemu-devel] [PATCH] virtio: Add virtio-rng driver
Date: Sat, 21 Nov 2009 12:44:47 +0000	[thread overview]
Message-ID: <1258807488-6341-1-git-send-email-ian.molton@collabora.co.uk> (raw)

Hi folks,

This patch is a first cut at a driver for virtio-rng. Its not problem free, but it works.

Features:
* Raw and EGD protocol support
* Rate limiting (simple)

Known problems:
* provokes a bug in the kernels virtio-rng driver that results in data
  corruption.
* Does not reconnect to the host when using a socket to get data (qemu
  limitation?)

Todo:
* Add burst rate limiting
* Reconnection support

With a patch to the guest kernel to fix the virtio-rng driver, I see no FIPS-140-2 test failures.

Please review!
