In win8 we have a feature that allows for interrupt driven flow management for host/guest communication. For instance, if the host were blocked because there was no space available in the ringbuffer, the host could request that the guest send an interrupt when space becomes available in the ringbuffer (when the guest drains the ringbuffer). While this feature was implemented in the guest a while ago, we had not advertised that the guest supported this feature. This patch advertises the support to the host. For pre-win8 hosts, this has no effect since the size of the ringbuffer control structure has not changed and all changes have been backward compatible - unused/reserved space has been used to implement this feature. In this version of the patch I have cleaned up the commit log based on feedback from Greg KH. Signed-off-by:

Minimize failures in this function by pre-allocating the buffer for posting messages. The hypercall for posting the message can fail for a number of reasons: 1. Transient resource related issues 2. Buffer alignment 3. Buffer cannot span a page boundry We address issues 2 and 3 by preallocating a per-cpu page for the buffer. Transient resource related failures are handled by retrying by the callers of this function. This patch is based on the investigation done by Dexuan Cui <decui@microsoft.com>. I would like to thank Sitsofe Wheeler <sitsofe@yahoo.com> for reporting the issue and helping in debuggging. Signed-off-by: -

Eliminate calls to BUG_ON() in vmbus_close_internal(). We have chosen to potentially leak memory, than crash the guest in case of failures. In this version of the patch I have addressed comments from Dan Carpenter (dan.carpenter@oracle.com). Signed-off-by:

Eliminate the call to BUG_ON() by waiting for the host to respond. We are trying to reclaim the ownership of memory that was given to the host and so we will have to wait until the host responds. Signed-off-by:

Eliminate calls to BUG_ON() by properly handling errors. In cases where rollback is possible, we will return the appropriate error to have the calling code decide how to rollback state. In the case where we are transferring ownership of the guest physical pages to the host, we will wait for the host to respond. Signed-off-by:

Posting messages to the host can fail because of transient resource related failures. Correctly deal with these failures and increase the number of attempts to post the message before giving up. In this version of the patch, I have normalized the error code to Linux error code. Signed-off-by:

In some condition we receive the break interrupt but nothing is putted in the Rx FIFO and the correspondend bit in the status register is not set. Thus, no-one clear the interrupt and the handler will be called forever. This patch clear the break interrupt as soon as it occurs. Then, if the break character '\0' is putted in the fifo we will manage it. We can also unmask the Break interrupt but its bit in ISR is still set on break. So I think is better to keep the registers clean. Signed-off-by:

When the GenWQE hardware queue was busy, the driver returned simply -EBUSY. This caused polling by applications which increased the load on the already busy system. This change implements the possiblity to sleep on a waitqueue instead when the DDCB queue is busy. The requestor is woken up when there is free space on the queue again. The old way to get -EBUSY is still available if the device is openend with O_NONBLOCKING. The default is now blocking behavior. Signed-off-by:
