The hardware alarm only supports one-minute accuracy which is coarse and disables UIE usage. Use the 1-second interrupt to achieve per-second accuracy. It is activated once we hit the per-minute alarm. The new feature is optional. When there is no 1-second interrupt, old behaviour with per-minute accuracy is used as before. With this feature, all tests of 'rtctest' are successfully passed.

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.
