In an ideal world, CNTFRQ_EL0 always contains the timer frequency for the kernel to use. Sadly, we get quite a few broken systems where the firmware authors cannot be bothered to program that register on all CPUs, and rely on DT to provide that frequency. So when trapping CNTFRQ_EL0, make sure to return the actual rate (as known by the kernel), and not CNTFRQ_EL0.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
