[PATCHv7 0/4] virtio_console: Add rproc_serial driver
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
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.

[PATCHv6 0/3] virtio_console: Add rproc_serial device
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

[PATCHv2] virtio_console: Add support for remoteproc serial
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
Add a simple serial connection driver called
VIRTIO_ID_RPROC_SERIAL (0xB) 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

[RFCv2 1/2] virtio_console: Add support for DMA memory allocation
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
Add feature VIRTIO_CONSOLE_F_DMA_MEM. 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.

[PATCH V2 0/6] virtio-trace: Support virtio-trace
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

[PATCH 0/6] virtio-console: spec compliance fixes
Turns out virtio console tries to take a buffer out of an active vq.
Works by sheer luck, and is explicitly forbidden by spec. And while
going over it I saw that error handling is also broken -
failure is easy to trigger if I force allocations to fail.
Lightly tested.
Michael S. Tsirkin (6):
virtio_console: don't tie bufs to a vq
virtio: add ability to iterate over vqs
