If CNTVCT or CNTPCT are read while they are updated with the lower 32bits rolled-over, it is possible to read a wrong value(both AArch32 or AArch64). So if the low 32 bits are set, we need to reread the counter. Change-Id: Ifd9720c8ff6d0622610b8f53d029635b3130280a Signed-off-by: Cong Zhang <congzhan@codeaurora.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.
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.
