Question regarding Virtio Console and Remoteproc
Hi Amit and Rusty,
I've been looking into the possibility of using the Virtio Console
Driver together with the remoteproc framework to communicate with
ST-Ericsson modem over shared memory.
It seems like Virtio Console would be a good fit, except for a issue
with buffer allocation. Due to HW limitations the STE-Modem cannot
access kernel memory (no IOMMU and limited address range). Instead

[PATCHv3 vringh] caif_virtio: Introduce caif over virtio
From: Erwan Yvin <erwan.yvin at stericsson.com>
Add the CAIF Virtio shared memory driver for talking
to a modem.
This CAIF Link layer communicates to the modem over
shared memory. It is implemented as a virtio_driver.
The underlying virtio device is managed by the remoteproc
framework. The Virtio queue is used for transmitting data
to the modem, and the new vringh is used for receiving

[RFC virtio-next 0/4] Introduce CAIF Virtio and reversed Vrings
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.

[PATCHv2] virtio: Introduce vringh wrappers in virtio_config
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
Add wrappers for the host vrings to support loose
coupling between the virtio device and driver.
A new struct vringh_config_ops with the functions
find_vrhs() and del_vrhs() is added to the virtio_device
struct. This enables virtio drivers to manage virtio
host rings without detailed knowledge of how the
vrings are created and

[PATCHv2 vringh 0/3] Introduce CAIF Virtio driver
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
This driver depends on Rusty's new host virtio ring implementation,
so this patch-set is based on the vringh branch in Rusty's git.
Changes since V1:
- Use the new iov helper functions, and simplify iov handling.
However this triggers compile warnings, as it takes struct iov
while kernel api uses struct kiov
- Introduced

Unexpected ISDN hangup on outbound call
We have setup an asterisk box to let everybody call into the university
internal network, but I get unexpected hangups when doing an outbound call
from SIP to the ISDN interface, and it happens from 20 seconds to some minutes into the
call.

[RFC] remoteproc: Add support for host-side (reversed) vrings
From: Sjur Br?ndeland <sjur.brandeland at stericsson.com>
Hi Ohad, Ido and Rusty.
Rusty has implemented host-side virtio ring. I will be using vringh
for the caif_virtio driver. But we need to figure out how to
integrate the vringh into remoteproc. Below is my initial stab on this.
This code is completely untested, but I'd love to get some initial
feedback on this.

Error: NA/NaN/Inf in foreign function call (arg 1)
Hi,
I have a huge data table with several variables containing missing values. I
want to make a simple scatter plot (Mass, HSI) and draw a smooth regression
on it.
Here are the summaries of these two variables:
