Implement the SVE save/restore for nVHE, following a similar logic to that of the VHE implementation: - the SVE state is switched on trap from EL1 to EL2 - no further changes to ZCR_EL2 occur as long as the guest isn't preempted or exit to userspace - ZCR_EL2 is reset to its default value on the first SVE access from the host EL1, and ZCR_EL1 restored to the default guest value in vcpu_put() Acked-by: Will Deacon <will@kernel.org> Signed-off-by: Marc Zyngier <maz@kernel.org>
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.
