Pull virtio update from Rusty Russell: "Some nice cleanups, and even a patch my wife did as a "live" demo for Latinoware 2012. There's a slightly non-trivial merge in virtio-net, as we cleaned up the virtio add_buf interface while DaveM accepted the mq virtio-net patches." * tag 'virtio-next-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rusty/linux: (27 commits) virtio_console: Add support for remoteproc serial virtio_console: Merge struct buffer_token into struct port_buffer virtio: add drv_to_virtio to make code clearly virtio: use dev_to_virtio wrapper in virtio virtio-mmio: Fix irq parsing in command line parameter virtio_console: Free buffers from out-queue upon close virtio: Convert dev_printk(KERN_ to dev_( virtio_console: Use kmalloc instead of kzalloc virtio_console: Free buffer if splice fails virtio: tools: make it clear that virtqueue_add_buf() no longer returns > 0 virtio: scsi: make it clear that virtqueue_add_buf() no longer returns > 0 virtio: rpmsg: make it clear that virtqueue_add_buf() no longer returns > 0 virtio: net: make it clear that virtqueue_add_buf() no longer returns > 0 virtio: console: make it clear that virtqueue_add_buf() no longer returns > 0 virtio: make virtqueue_add_buf() returning 0 on success, not capacity. virtio: console: don't rely on virtqueue_add_buf() returning capacity. virtio_net: don't rely on virtqueue_add_buf() returning capacity. virtio-net: remove unused skb_vnet_hdr->num_sg field virtio-net: correct capacity math on ring full virtio: move queue_index and num_free fields into core struct virtqueue. ...

We simplified virtqueue_add_buf(), make it clear in the callers. Signed-off-by: Rusty Russell

tools:virtio: fix compilation warning

2012-12-06T15:09:17Z

We do not allow old-style function definition. Always spell foo(void) if a function does not take any parameters. Signed-off-by: Cong Ding Signed-off-by: Michael S. Tsirkin

tools: Fix pthread flag for Makefile of trace-agent used by virtio-trace

2012-09-28T05:35:13Z

pthread flag should not be -lpthread but -pthread using gcc. The -lpthread links the external multithread library. On the other hand, the -pthread manages both the gcc's preprocessor and linker to be able to compile with pthread. Signed-off-by: Yoshihiro YUNOMAE Signed-off-by: Rusty Russell

tools: Add guest trace agent as a user tool

2012-09-28T05:35:13Z

This patch adds a user tool, "trace agent" for sending trace data of a guest to a Host in low overhead. This agent has the following functions: - splice a page of ring-buffer to read_pipe without memory copying - splice the page from write_pipe to virtio-console without memory copying - write trace data to stdout by using -o option - controlled by start/stop orders from a Host Changes in v2: - Cleanup (change fprintf() to pr_err() and an include guard) Signed-off-by: Yoshihiro YUNOMAE Acked-by: Amit Shah Signed-off-by: Rusty Russell

Make tool build after virtio changes broke it. Signed-off-by: Michael S. Tsirkin

Make the tool build again after virtio changes broke it. Signed-off-by: Michael S. Tsirkin

virtio: rename virtqueue_add_buf_gfp to virtqueue_add_buf

2012-01-12T05:14:42Z

Remove wrapper functions. This makes the allocation type explicit in all callers; I used GPF_KERNEL where it seemed obvious, left it at GFP_ATOMIC otherwise. Signed-off-by: Rusty Russell Reviewed-by: Christoph Hellwig
