Hi,
I am using kernel 2.6.15.7 <http://2.6.15.7/> and Xenomai 2.1
While writing this mail I noticed the probable reason.
parameter
#define CONFIG_X86_TSC 1 should be
#define CONFIG_XENO_X86_TSC 1
I changed this in src/include/xeno_config.h
After recompile testsuit worked.
I changed the same in
src/include/xeno_config.h.in
original line
#undef CONFIG_X86_TSC
changed to.
#undef CONFIG_XENO_X86_TSC
Then normal ./configure ... make etc.
It worked.
By luck since you only circumvented the proper checks, unfortunately.
The variables as defined in the configure script are perfectly ok,
CONFIG_X86_TSC is the right option to set.
The message you got initially told you that a discrepancy between the
CPU selected at kernel level and the user-support has been detected. To
fix this, you need to select a x86 CPU supporting a timestamp counter
when configuring your kernel, since by default, the configure script
assumes --enable-x86-tsc.
In any case, keep in mind that updating the configure script output
(xeno_config.h) by hand is always the wrong way to fix an issue.
Thanks,

I get following error while running test suit.
Xenomai: incompatible feature set
(required="sep tsc", present="sep", missing="tsc").
I configured the xenomai with
./configure --enable-x86-tsc --enable-x86-sep
config.log file entries

cat /proc/cpuinfo shows sep and tsc.
