2012-12-18virtio_console: Add support for remoteproc serialSjur Brændeland2-23/+170
Add a simple serial connection driver called VIRTIO_ID_RPROC_SERIAL (11) for communicating with a remote processor in an asymmetric multi-processing configuration. This implementation reuses the existing virtio_console implementation, and adds support for DMA allocation of data buffers and disables use of tty console and the virtio control queue.

2012-12-18virtio_console: Merge struct buffer_token into struct port_bufferSjur Brændeland1-76/+53
Refactoring the splice functionality by unifying the approach for sending scatter-lists and regular buffers. This simplifies buffer handling and reduces code size. Splice will now allocate a port_buffer and send_buf() and free_buf() can always be used for any buffer.

2012-12-18virtio-mmio: Fix irq parsing in command line parameterPawel Moll1-9/+17
When the resource_size_t is 64-bit long, the sscanf() on the virtio device command line paramter string may return wrong value because its format was defined as "%u". Fixed by using an intermediate local value of a known length. Also added cleaned up the resource creation and added extra comments to make the parameters parsing easier to follow.

2012-12-18virtio_console: Use kmalloc instead of kzallocSjur Brændeland1-1/+1
Avoid the more cpu expensive kzalloc when allocating buffers. Originally kzalloc was intended for isolating the guest from the host by not sending random guest data to the host.

2012-12-18virtio-net: correct capacity math on ring fullMichael S. Tsirkin1-5/+4
Capacity math on ring full is wrong: we are looking at num_sg but that might be optimistic because of indirect buffer use. The implementation also penalizes fast path with extra memory accesses for the benefit of ring full condition handling which is slow path. It's easy to query ring capacity so let's do just that. This change also makes it easier to move vnet header for tx around as follow-up patch does. Signed-off-by: Michael S.

time. Git commit 30106c174311b8cfaaa3186c7f6f9c36c62d17da ("x86, hotplug: Support functions for CPU0 online/offline") alters what the call to smp_store_cpu_info() does. For BSP we should use the smp_store_boot_cpu_info() and for secondary CPU's the old variant of smp_store_cpu_info() should be used. This fixes the regression introduced by said commit.
