For PERF_SAMPLE_BRANCH_STACK sample type, different branch_sample_type, ie branch filters are supported. All the branch filters are not supported in powerpc. Example, power10 platform supports any, ind_call and cond branch filters. Whereas, it is different in power9. Testcase checks event open for invalid and valid branch sample types. The branch types for testcase are picked from "perf_branch_sample_type" in perf_event.h Signed-off-by: Athira Rajeev <atrajeev@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/20220610134113.62991-13-atrajeev@linux.vnet.ibm.com
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.
