The ins_lat of PERF_SAMPLE_WEIGHT_STRUCT stands for the instruction latency, which is only available for X86. Add a X86 specific test for the ins_lat and PERF_SAMPLE_WEIGHT_STRUCT type. The test__x86_sample_parsing() uses the same way as the test__sample_parsing() to verify a sample type. Since the ins_lat and PERF_SAMPLE_WEIGHT_STRUCT are the only X86 specific sample type for now, the test__x86_sample_parsing() only verify the PERF_SAMPLE_WEIGHT_STRUCT type. Other sample types are still verified in the generic test. $ perf test 77 -v 77: x86 Sample parsing : --- start --- test child forked, pid 102370 test child finished with 0 ---- end ---- x86 Sample parsing: Ok Signed-off-by: Kan Liang <kan.liang@linux.intel.com> Cc: Athira Jajeev <atrajeev@linux.vnet.ibm.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Sumanth Korikkar <sumanthk@linux.ibm.com> Cc: Sven Schnelle <svens@linux.ibm.com> Cc: Thomas Richter <tmricht@linux.ibm.com> Cc: Vasily Gorbik <gor@linux.ibm.com> Link: http://lore.kernel.org/lkml/1614787285-104151-2-git-send-email-kan.liang@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.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.
