rpmsg: virtio_rpmsg_bus: fix sg_set_buf() when addr is not a valid kernel address

2017-08-24T22:37:28Z

To specify memory for remoteproc, we declare (dma_declare_coherent_memory()) an area which is ioremap'ed to the vmalloc area. However, this address is not a kernel address so virt_addr_valid(buf) fails.

rpmsg: virtio_rpmsg: set rpmsg_buf_size customizable

2017-08-24T22:37:10Z

Rpmsg buffer size is currently fixed to 512 bytes. This patch introduces a new capability in struct virtproc_info to tune shared buffer size between host and coprocessor according to the needs. Acked-by: Suman Anna Signed-off-by: Loic Pallardy Signed-off-by: Bjorn Andersson

rpmsg: virtio_rpmsg_bus: fix export of rpmsg_send_offchannel_raw()

2017-07-26T17:00:48Z

Commit 8a228ecfe086b ("rpmsg: Indirection table for rpmsg_endpoint operations") has made the rpmsg_send_offchannel_raw() a static function and local to the virtio_rpmsg_bus module, but has not dropped the corresponding EXPORT_SYMBOL. Fix this. Signed-off-by: Suman Anna Signed-off-by: Bjorn Andersson

rpmsg: virtio_rpmsg_bus: cleanup multiple assignment to ops

2017-06-25T21:43:31Z

Trivial cleanup: the .ops pointer is assigned twice. This patch removes the first assignment. Acked-by: Suman Anna Signed-off-by: Henri Roosen Signed-off-by: Bjorn Andersson

rpmsg: virtio_rpmsg_bus: fix nameservice address

2017-06-25T21:39:18Z

Commit 2a48d7322dc8 ("rpmsg: rpmsg_send() operations takes rpmsg_endpoint") only changed the nameservice address for virtio_rpmsg_announce_create() but did not do the same change for virtio_rpmsg_announce_destroy(). Signed-off-by: Henri Roosen Signed-off-by: Bjorn Andersson

rpmsg: virtio_rpmsg_bus: fix announce for devices without endpoint

2017-06-25T21:35:02Z

A device might not have an endpoint assigned. This patch checks if rpdev->ept has a value before dereferencing or using it. Signed-off-by: Henri Roosen Signed-off-by: Bjorn Andersson

rpmsg: Release rpmsg devices in backends

2017-05-17T17:30:22Z

The rpmsg devices are allocated in the backends and as such must be freed there as well. Signed-off-by: Bjorn Andersson

virtio: wrap find_vqs

2017-05-02T20:41:42Z

We are going to add more parameters to find_vqs, let's wrap the call so we don't need to tweak all drivers every time. Signed-off-by: Michael S. Tsirkin

virtio: allow drivers to request IRQ affinity when creating VQs

2017-02-27T18:54:04Z

Add a struct irq_affinity pointer to the find_vqs methods, which if set is used to tell the PCI layer to create the MSI-X vectors for our I/O virtqueues with the proper affinity from the start. Compared to after the fact affinity hints this gives us an instantly working setup and allows to allocate the irq descritors node-local and avoid interconnect traffic. Last but not least this will allow blk-mq queues are created based on the interrupt affinity for storage drivers. Signed-off-by: Christoph Hellwig Reviewed-by: Jason Wang Signed-off-by: Michael S.

rpmsg: Allow callback to return errors

2016-09-09T05:15:25Z

Some rpmsg backends support holding on to and redelivering messages upon failed handling of them, so provide a way for the callback to report and error and allow the backends to handle this. Signed-off-by: Bjorn Andersson
