[Xenomai-help] problem with testsuite/latency

[Nicola Pezzotti]

Hi.

	I also have some problem with Xenomai.

I solve the kernel's compilation problem and I compile Xenomai

(Kernel 2.6.16 Xenomai 2.2.0)

Now I trying to launch the testsuite's latency program but I have this 
problem:


Xenomai: incompatible feature set
(required="sep tsc", present="sep", missing="tsc").


Someone can give my an hint?

thanks

Your kernel is lacking TSC support. Either enable it there (check if you
picked the right CPU type) or switch it off for user-space (configure
--disable-x86-tsc).

[We should make that message above a bit more expressive: Missing...
where? Also, could someone write an entry for TROUBLESHOOTING?]

Your kernel config says that your x86 CPU does not provide any
time-stamp counter, but the user-space programs ask for it. If the
kernel config is right (i.e. the CPU selection is correct), then you
need to switch off the TSC requirement [which defaults to on] when
configuring the user-space Xenomai support: e.g.

.../configure --disable-x86-tsc

$ make clean install 

README.INSTALL has more on feature selection, and explains why we must
enforce it.
