[Qemu-devel] [PATCH 0/8] virtio-rng: hardware random number generator device

[Amit Shah <amit.shah@redhat.com>]

Hello,

Reviving this series last sent by Anthony to the list.  The
differences are minimal from the time Anthony sent, just rebasing to
the current tree and fixing a couple of minor bugs.

I've not really looked in detail at the object patches -- mostly just
concerned about the device itself.

Please review and apply if appropriate.

Changes from last submission:
- Fix a few typos/whitespaces in rng.h
- Switch to virtqueue_get_avail_bytes(): helps remove the
  savevm/loadvm complexities and provides a cleaner interface
- Remove the older qevent hunks that got left behind
- Rebase to master
- Bugfix: rng_backend_request_entropy() in chr_read() should pass len,
  not size
- Do not request for more entropy in chr_read() once the current
  request is served; there are other ways this notification will go
  out.
