Similarly to handling the physical timer accesses early when FEAT_ECV causes a trap, we try to handle the physical counter without returning to the general sysreg handling. More surprisingly, we introduce something similar for the virtual counter. Although this isn't necessary yet, it will prove useful on systems that have a broken CNTVOFF_EL2 implementation. Yes, they exist. Acked-by: Oliver Upton <oliver.upton@linux.dev> Link: https://lore.kernel.org/r/20241217142321.763801-7-maz@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 reStructuredText 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.
