Hi
Currently I'm using Xenomai-2.5.6. Now I need to do some tests on the
most recent repository version.
Previously I was using the option --enable-arm-tsc in the configuration
step. In Xenomai-2.6 this options seems still to be present, however it
behaves like the old option --enable-arm-arch. I think this behavior is
wrong.
In addition I'd like to know if --enable-arm-tsc is selected
automatically of if it is still necessary to use this option.
Best regards,
Michael

You probably do not need --enable-arm-tsc. For more details, see
README.INSTALL.

--enable-arm-tsc DOES NOT behave like the old option --enable-arm-arch.
Hence the rename.

For me, doing the transition form Xenomai-2.5 to 2.6, it was just
confusing that --enable-arm-tsc has exactly the same help text as the
old --enable-arm-arch. It would be probably good to add an additional
sentence to explain why one has to select the architecture for this
option. Something like this:
"To enable the correct TSC user-space implementation, select for which ..."

Right. But --enable-arm-tsc does not enable the correct TSC user-space
implementation. It is an option only useful for old I-pipe patches that
did not support the "kuser" tsc implementation. So, using this option
with Xenomai 2.6.0 is probably not what you want to do.
