Linux kernel commit 00facc760903 ("perf jevents: Switch build to use
jevents.py") switched to auto-generation of arch-specific PMU events
using python script. Now custom PMU events for different platforms of
the selected target architecture are not embedded into perf binary if
an appropriate host python interpreter is not present. In practice it
means that perf is successfully built, but 'perf list pmu' will show
no custom events on a target platform even if those events are supported
and properly defined in tools/perf/pmu-events/arch/<target arch>
directory in the kernel source tree.
Since building host-python3 is not instantaneous, add a config option,
like we have in the kernel for a bunch of host packages, to id=ndicate
that host-python3 is required, and only add the dependency in that case.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
