Hi Rusty, These are a few fixes for the virtio-rng driver. These were tested using the not-yet-upstream virtio-rng device patch to qemu: http://thread.gmane.org/gmane.comp.emulators.qemu/152668 Please apply. Amit Shah (5): virtio ids: fix comment for virtio-rng virtio: rng: allow tasks to be killed that are waiting for rng input virtio: rng: don't wait on host when module is going

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

If the architecture has DMA support and this feature bit is set, the virtio data buffers will be allocated from DMA memory. If the device requests the feature VIRTIO_CONSOLE_F_DMA_MEM, but the architecture don't support DMA the driver's probe function will fail. This is needed for using

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

This patch-set introduces the CAIF Virtio Link layer. The purpose is to communicate with a remote processor (a modem) over shared memory. Virtio is used as the transport mechanism, and the Remoteproc framework provides configuration and management of the Virtio rings and devices. The modem and Linux host may be on the same SoC, or connected over a shared memory interface such as LLI. Zero-Copy
