vhost: support event index

2011-05-30T01:44:15Z

Support the new event index feature. When acked, utilize it to reduce the # of interrupts sent to the guest. Signed-off-by: Michael S. Tsirkin Signed-off-by: Rusty Russell

vhost-net: remove unlocked use of receive_queue

2011-03-13T21:08:19Z

Use of skb_queue_empty(&sock->sk->sk_receive_queue) without taking the sk_receive_queue.lock is unsafe or useless. Take it out. Reported-by: Eric Dumazet Signed-off-by: Michael S. Tsirkin

vhost: lock receive queue, not the socket

2011-03-13T21:08:04Z

vhost takes a sock lock to try and prevent the skb from being pulled from the receive queue after skb_peek. However this is not the right lock to use for that, sk_receive_queue.lock is. Fix that up. Signed-off-by: Michael S. Tsirkin

vhost-net: Unify the code of mergeable and big buffer handling

2011-03-13T15:00:10Z

Codes duplication were found between the handling of mergeable and big buffers, so this patch tries to unify them. This could be easily done by adding a quota to the get_rx_bufs() which is used to limit the number of buffers it returns (for mergeable buffer, the quota is simply UIO_MAXIOV, for big buffers, the quota is just 1), and then the previous handle_rx_mergeable() could be resued also for big buffers.

vhost-net: check the support of mergeable buffer outside the receive loop

2011-03-13T14:57:30Z

No need to check the support of mergeable buffer inside the recevie loop as the whole handle_rx()_xx is in the read critical region. So this patch move it ahead of the receiving loop. Signed-off-by: Jason Wang Signed-off-by: Michael S. Tsirkin

vhost: Cleanup vhost.c and net.c

2011-03-08T16:02:47Z

Minor cleanup of vhost.c and net.c to match coding style. Signed-off-by: Krishna Kumar Signed-off-by: Michael S. Tsirkin

vhost: rcu annotation fixup

2011-02-01T14:48:46Z

When built with rcu checks enabled, vhost triggers bogus warnings as vhost features are read without dev->mutex sometimes, and private pointer is read with our kind of rcu where work serves as a read side critical section. Fixing it properly is not trivial. Disable the warnings by stubbing out the checks for now. Signed-off-by: Michael S. Tsirkin

vhost/net: fix rcu check usage

2010-11-25T09:29:16Z

Incorrect rcu check was used as rcu isn't done under mutex here. Force check to 1 for now, to stop it from complaining. Signed-off-by: Michael S. Tsirkin
