Windows uses a per-vCPU vector, and it's delivered via the local APIC basically like an MSI (with associated EOI) unlike the traditional guest-wide vector which is just magically asserted by Xen (and in the KVM case by kvm_xen_has_interrupt() / kvm_cpu_get_extint()). Now that the kernel is able to raise event channel events for itself, being able to do so for Windows guests is also going to be useful.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
