The Topdown metrics events were added as 'perf stat' default events since commit 42641d6f4d15e6db ("perf stat: Add Topdown metrics events as default events"). However, the perf attr tests were not updated accordingly. The perf attr test fails on the platform which supports Topdown metrics. # perf test 17 17: Setup struct perf_event_attr :FAILED! Add Topdown metrics events into perf attr test cases. Make them optional since they are only available on newer platforms.

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.
