2014-09-23Drivers: hv: vmbus: Enable interrupt driven flow controlK. Y. Srinivasan1-0/+5
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: K. Y. Srinivasan <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2014-09-23Drivers: hv: vmbus: Cleanup hv_post_message()K. Y. Srinivasan2-12/+19
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 <[email protected]>. I would like to thank Sitsofe Wheeler <[email protected]> for reporting the issue and helping in debuggging. Signed-off-by: K. Y.

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.

2014-09-23ipoctal: clear break interrupt as soon as it occursFederico Vaga1-1/+3
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.

2014-09-23GenWQE: Support blocking when DDCB queue is busyFrank Haverkamp4-22/+57
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.

false-positives We definitely know that only x86 (32-bit) architecture is affected by the issue, so implement a stub instead of the actual check for other architectures. We also know that motherboard LPT chipset is affected, so the port is either come from parport_pc_init (when `io' module param is used) or parport_pc_find_isa_ports (when default LPT ports are probbed: 0x378, 0x278, 0x3bc).

2014-09-23pcie-gadget-spear: use devm_ functionsHimangi Saraogi1-75/+23
The various devm_ functions allocate memory that is released when a driver detaches. This patch uses these functions for data that is allocated in the probe function of a platform device and is only freed in the remove function. Also, the unnecessary labels are removed and linux/device.h is added to make sure the devm_*() routine declarations are unambiguously available. The initial call to platform_get_resource is moved down to the introduced call to devm_ioremap_resource that uses its result.
