aux-output events need to have an AUX area event as the group leader. However, grouping events does not allow the AUX area event to be given an address filter because the --filter option must come after the event, which conflicts with the grouping syntax. To allow filtering in that case, automatically create a group since that is the requirement anyway. Example: (requires Intel Tremont) perf record -c 500 -e 'intel_pt//u' --filter 'filter main @ /bin/ls' -e 'cycles/aux-output/pp' ls Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Link: http://lore.kernel.org/lkml/20210121140418.14705-1-adrian.hunter@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.
