Testcase to ensure that using invalid event in generic event for PERF_TYPE_HARDWARE will fail. Invalid generic events in power10 are: - PERF_COUNT_HW_BUS_CYCLES - PERF_COUNT_HW_STALLED_CYCLES_FRONTEND - PERF_COUNT_HW_STALLED_CYCLES_BACKEND - PERF_COUNT_HW_REF_CPU_CYCLES Invalid generic events in power9 are: - PERF_COUNT_HW_BUS_CYCLES - PERF_COUNT_HW_REF_CPU_CYCLES Testcase does event open for valid and invalid generic events to ensure event open works for all valid events and fails for invalid events.

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.
