“Fast symbol resolution:
“Alan Jenkins has been doing some great work on the Linux Kernel
Module (LKM) module loader and tools over the past few years. I
have had the privilege to work with him a number of times in my
capacity as maintainer of some of those tools, and am always
impressed by his work. The latest patches add support for a binary
searchable kernel symbol index, generated during the kernel
compilation and used by the running kernel for more expediently
resolving symbols needed by modules. With this work, the kernel
takes even less time to boot on modern netbook systems like
his.“KVM para-virtualisation improvements:
KVM (Kernel-based Virtual Machine) enables users to exploit modern
hardware virtualisation features available on Intel-compatible
systems. The (optional) para-virtualisation features go a stage
further by allowing virtualisation-aware guests’ operating systems
running under KVM to take advantage of improved performance
optimisations. For example, a recent modification to KVM allows for
para-virtualised guests experiencing a page fault (due to memory
being temporarily in on disk swap space) to suspend only the
faulting guest OS process and not the entire guest. The guest is
then free to continue running other processes while the host
machine running KVM completes the faulting in of the necessary
data.”
