[rt-tests v2 v2 00/20] rt-numa.h cleanups

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This series cleans up the rt-numa.h header.

As we have a hard dependency on libnuma we can simplify the code in
cyclictest. This allows remove all the small helpers in rt_numa.h. And
with this we can remove the header and reduce the confusion with
rt-numa.h

While at it, I simplified the --smp vs --affinity vs --threads
logic. There is no need for additional variables to keep state. With
this we also make --affinity to behave as with the rest of
rt-tests. That is a plan -a will be the same as with -S. There is no
need for -S anymore but I think we should leave it in place for
backwards compatibility. I suspect, there must be a lot of muscle
memory out there :)

Since signaltest has the same code as cyclictest, cleanup this tool as
well.

With all those cleanups in cyclictest and signaltest, rt-numa.h
contains only a three functions. The final part of the series is to
remove unnecessary function arguments (max_cpus). This also fixes the
theoretical problem that a sparse cpumask would not be handled
correctly.

changes v2:
  - added more cleanup patches (7-20)
