This is similar to the recent --no-sr option - it's a change that is unlikely to ever be used except by someone testing whether a client is compliant to the protocol, but in that niche case, it can be quite handy (it's a lot nicer to be able to purposefully cripple a server from the command line than from a one-off compile, when testing if a client's fallback for a spec-compliant but

The attached patches allow the pciback module to perform a reset whenever a PCI device is: - attached to the pciback module, as so: echo "0000:01.07.0" > /sys/bus/pci/devices/pciback/bind - detached from the pciback module, as so: echo "0000:01.07.0" > /sys/bus/pci/devices/pciback/unbind - and when the guest is done with (internally when the guest is not using

Memory fragmentation introduced by ballooning might reduce significantly the number of 2MB contiguous memory blocks that can be used within a guest, thus imposing performance penalties associated with the reduced number of transparent huge pages that could be used by the guest workload. This patch-set follows the main idea discussed at 2012 LSFMMS session: "Ballooning for transparent huge

Hi Dan, Jérôme and Jason, below is a series that cleans up the dev_pagemap interface so that it is more easily usable, which removes the need to wrap it in hmm and thus allowing to kill a lot of code Note: this series is on top of Linux 5.2-rc5 and has some minor conflicts with the hmm tree that are easy to resolve.

Hi all, The series is a draft of generic MSI driver that supports PCI and Non-PCI device which have MSI capability. If you're not interested it, sorry for the noise. The series is based on Linux-3.16-rc1. MSI was introduced in PCI Spec 2.2. Currently, kernel MSI driver codes are bonding with PCI device. Because MSI has a lot advantages in design. More and more non-PCI devices want to use
