This patch-set introduces a new virtio type "rproc_serial" for communicating with remote processors over shared memory. The driver depends on the the remoteproc framework. As preparation for introducing "rproc_serial" I've done a refactoring of the transmit buffer handling. NOTE: These two patches are identical to first two patches of the V8 patch-set, but are rebased to

From: Sjur Br?ndeland <sjur.brandeland at stericsson.com> I thought rebasing rproc_serial to linux-next was going to be trivial. But when starting the merge I realized that I had to refactor the the patches from Masami Hiramatsu. The splice support has the same issue as I faced, with different type of buffers in the out_vq. So I ended up refactoring the splice functionality. The code size

Hi All, The following patch set provides a low-overhead system for collecting kernel tracing data of guests by a host in a virtualization environment. A guest OS generally shares some devices with other guests or a host, so reasons of any problems occurring in a guest may be from other guests or a host. Then, to collect some tracing data of a number of guests and a host is needed when some
