TODO list for qemu+KVM networking performance v2
As I'm new to qemu/kvm, to figure out how networking performance can be improved, I
went over the code and took some notes. As I did this, I tried to record ideas
from recent discussions and ideas that came up on improving performance. Thus
this list.
This includes a partial overview of networking code in a virtual environment, with
focus on performance: I'm only interested in sending

[PATCH v4 0/6] Suppor for various power sensors on GF100+
This is a complete rework from the first version I sent out.
Now the implementation is more centered around the power_rails we find in the
SENSE table instead of extdev centered. This makes the implementation a lot
easier and straightforward.
I've added support for the INA219, INA209 and INA3221 sensors found on multiple
Fermi and Kepler cards.
The power consumption is also exported via

[PATCH 4/6] staging: hv: Removed TODO for VMBUS, it mirrors HYPER-V behavior to closely
From: Hank Janssen <hjanssen at microsoft.com>
Removed TODO for VMBUS, it mirrors HYPER-V behaviour to closely and does not really share any
usable functionality of the Linux kernel facilities. There is not really an easy way to combine functionality.

virtio over PCI
...also got started with the alacrityvm project, developing a driver for
their virtualization framework. That project is nowhere near finished.
The virtualization folks basically told GHaskins (alacrityvm author)
that alacrityvm wouldn't ever make it to mainline Linux.

Unfortunately, I've been pulled onto other projects for the time being.
However, I'd really like to be able to use a virtio-over-PCI style
driver, rather than relying on my own custom (slow, unoptimized) network
driver (PCINet).

[PATCH 0/2] Support for INA3221 power sensor
The INA3221 is usually found on mid and high end kepler+ gpus
Marins Patch implements the new iccsense subdev and all needed bits for the
INA3221 power sensor.
My Patch implements the hwmon power1 interface to expose the current power
consumption through hwmon (and can be read out via sysfs or the sensors tool)
Please test these patches for Fermi+ GPUs, that nothing gets messed up and

[PATCH RFC 0/7] vhost: cross-endian support (vhost-net only)
Hi,
This series allows QEMU to use vhost with legacy virtio devices when
host and target don't have the same endianness. Only network devices
are covered for the moment.
I had already posted a series some monthes ago but it never got reviewed.
Moreover, the underlying kernel support was entirely re-written and is still
waiting to be applied by Michael. I hence post as RFC.

tws bug ? (LSI SAS 9750)
Hi,
I have been trying out a nice new tws controller and decided to enable
debugging in the kernel and run some stress tests. With a regular
GENERIC kernel, it boots up fine. But with debugging, it panics on
boot. Anyone know whats up ? Is this something that should be sent
directly to LSI ?
