Linus,

Note, the biggest change here is the restructuring of the Makefiles to
warn about missing libraries that you asked us to do last merge window.
It follows perf in which you don't have the libraries, you now get:
Auto-detecting system features:
... libtraceevent: [ OFF ]
... libtracefs: [ OFF ]
libtraceevent is missing. Please install libtraceevent-dev/libtraceevent-devel
libtracefs is missing. Please install libtracefs-dev/libtracefs-devel
]
Updates to tools/tracing and verification for 6.9:
Tracing:
- Update makefiles for latency-collector and RTLA, using tools/build/
makefiles like perf does, inheriting its benefits. For example, having a
proper way to handle library dependencies.
- The timerlat tracer has an interface for any tool to use. rtla timerlat
tool uses this interface dispatching its own threads as workload. But,
rtla timerlat could also be used for any other process. So, add 'rtla
timerlat -U' option, allowing the timerlat tool to measure the latency of
any task using the timerlat tracer interface.
Verification:
- Update makefiles for verification/rv, using tools/build/ makefiles like
perf does, inheriting its benefits. For example, having a proper way to
handle dependencies.

Lovely. Now it all worked for me, and gave me the legible
Auto-detecting system features:
... libtraceevent: [ on ]
... libtracefs: [ OFF ]
libtracefs is missing. Please install libtracefs-dev/libtracefs-devel
Makefile.config:29: *** Please, check the errors above.. Stop.
and after installing libtracefs-devel as suggested it finished cleanly.
Let's see if it works for others too,
