Allow userspace to change the guest-visible value of the register with some severe limitation: - No changes to features not virtualized by KVM (AMU, MPAM, RAS) - Short of full GICv2 emulation in kernel, hiding GICv3 from the guest makes absolutely no sense. - FP is effectively assumed for KVM VMs. Signed-off-by: Jing Zhang <jingzhangos@google.com> [oliver: restrict features that are illogical to change] Reviewed-by: Marc Zyngier <maz@kernel.org> Link: https://lore.kernel.org/r/20231003230408.3405722-9-oliver.upton@linux.dev Signed-off-by: Oliver Upton <oliver.upton@linux.dev>
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.
