Hello,
changes since (implicit) v1 available at
https://lore.ptxdist.org/ptxdist/ZjtM5u8mjdcZjx-B@pengutronix.de/:
- split in two patches (suggested by Michael Tretter)
- drop commented out targets (suggested by Michael Tretter)
- install plugin libraries
- comment about unset meson config options
Michael requested that I explicitly set all configuration options to
their default value. This felt wrong as most of them don't matter when
documentation is disabled (which is the case here). So as a suggested
compromise I explicitly listed the unset options.
Best regards
Uwe

This is required for perf (PTXCONF_KERNEL_TOOL_PERF) to work with
tracepoints and enable the subcommands kmem, kwork, lock, sched and
timechart.

This makes it possible to use with tracepoints and enable the
subcommands kmem, kwork, lock, sched and timechart.
