Some of the bits in the event code is reserved for specific platforms. Event code bits 52-59 are reserved in power9, whereas in power10, these are used for programming Monitor Mode Control Register 3 (MMCR3). Bit 9 in event code is reserved in power9, whereas it is used for programming "radix_scope_qual" bit 18 in Monitor Mode Control Register 1 (MMCR1). Testcase to ensure that using reserved bits in event code should cause event_open to fail.

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.
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.
