With the new SBI PMU event info function, we can query the availability of the all standard SBI PMU events at boot time with a single ecall. This improves the bootime by avoiding making an SBI call for each standard PMU event. Since this function is defined only in SBI v3.0, invoke this only if the underlying SBI implementation is v3.0 or higher.

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.
