* virtio-net: unbreak the minix guestJason Wang2013-04-291-7/+8
| | | | | | | | | | | | | | | | | | Multiqueue patchset conditionally add control vq only when guest negotiate the feature. Though the spec is not clear on this but it breaks the minix guest since it will identify the ctrl vq even if it does not support it. Though this behavior seems a violation on the spec "If the VIRTIO_NET_F_CTRL_VQ feature bit is negotiated, identify the control virtqueue.", to keep the backward compatibility, always add the ctrl vq at end of the queues.

* pseries: Convert VIO code to QOM style type safe(ish) castsDavid Gibson2013-04-261-10/+14
| | | | | | | | | | | Curerntly the pseries VIO device code contains quite a few explicit uses of DO_UPCAST and plain C casts. This is (obviously) type unsafe, and not the conventional way of doing things in the QOM model. This patch converts the code to use the QOM convention of per-type macros to do verified casts with OBJECT_CHECK().

* qdev: Drop taddr propertiesPeter Maydell2013-04-201-1/+0
| | | | | | | | | | | | Drop all the infrastructure for taddr properties (ie ones which are 'hwaddr' sized). These are now unused, and any further desired use would be rather questionable since device properties shouldn't generally depend on a type that is conceptually variable based on the target CPU. 32 or 64 bit integer properties should be used instead as appropriate for the specific device.

* stream: Remove app argument hackPeter Crosthwaite2013-04-161-15/+85
| | | | | | | | | The uint32_t *app argument doesn't exist in real hardware. It was a hack in xilinx_axidma/enet to fake the (secondary) control stream connection.

* xilinx_axienet/dma: Implement rx path flow controlPeter Crosthwaite2013-04-161-3/+25
| | | | | | | | | | | | | | | Implement flow control for the RX data path from xilinx_axienet->xilinx_axidma. On short return from axidma, then ethernet sets up the notify callback to resume transfer from where it left off. This also allows the ethernet to track whether there is an in progress transaction and return false from ethernet can_receive() as appropriate. If the DMA backs up or is disabled it waits for enablement. When the rx stream IO region is touched, the can_push() notify function is called if set.

* stream: Add flow control APIPeter Crosthwaite2013-04-161-3/+5
| | | | | | | | | | Add basic flow control to stream. A stream slave may return short, indicating that it is not capable of accepting any more data at the present time. Polling or a callback can be used via the can_push() function to determine when the slave can receive again. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Edgar E.

* xilinx_axienet: Create Proxy object for streamPeter Crosthwaite2013-04-161-4/+56
| | | | | | | | | | | | | Create a separate child object to proxy the stream slave connection. This is setup for future work where a second stream slave connection is needed. The new child object is created at qdev init time and is linked back to the parent (the ethernet device itself) automatically. Stream slave masters differentiate which slave connection they are connected to by linking to the proxy object rather than the parent.
