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

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

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. Signed-off-by:Hank Janssen <hjanssen at microsoft.com> Signed-off-by:Haiyang Zhang <haiyangz at microsoft.com> ---

...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. http://www.mmarray.org/~iws/vbus/ 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). If you get something mostly working (and mostly agreed upon...

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 works as

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. The corresponding

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 ? pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0 pci0: <ACPI PCI bus> on pcib0

Hi to all. I'm experimenting with running a https://www.zotac.com/us/product/graphics_card/geforce%C2%AE-gt-710-1gb-pcie-x-1 card on an Nvidia Jetson TX2 arm64 device. Possible? Linux kernel aarch64 5.6.10. Because Nvidia did not list drivers for this architecture, I'm experimenting with a nouveau driver. The Jetson TX2 has a default driver for the host1x framebuffer for output from the
