[Xenomai-help] Error while running test suit (required="sep tsc", present="sep", missing="tsc").

Hi,

I am using kernel 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.

Thanks,

Deepak Joglekar

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

configure:20569: checking for x86 TSC support
configure:20579: result: y
#define CONFIG_X86_TSC 1

configure:20556: checking for x86 SEP instructions in syscalls
configure:20566: result: y
#define CONFIG_XENO_X86_SEP 1


cat /proc/cpuinfo shows sep and tsc.

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.

No, the issue is that you enable usage of tsc in user-space by
passing the --enable-x86-tsc to configure, whereas you choosed, in
kernel configuration, a processor without tsc enabled.

For the Record, can you post your actual error messages, in context,
so that folks who search the ML (gasp) for the "exact error message string"
will find it in your post ?

And it would be good to post the answer youve recieved also.

Hi,

For record complete results.

1. Initally I chose i686 processor family in kernel config. and followed
instructions for kernel and xenomai compile and install.
My processor is Pentium IV on build system. My Target processor will be AMD
Geode.

I was getting following error message while running xeno-test.
-----------------------------------------------------------
Xenomai: incompatible feature set
(required="sep tsc", present="sep", missing="tsc").
-----------------------------------------------------------

I checked /proc/cpuinfo
--------------------------------
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca
cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm pni
monitor ds_cpl est cid cx16 xtpr
--------------------------------

Then I was bit confused.

Gilles Chanteperdrix correctly pointed out error.

You should have "CONFIG_X86_TSC=y" in kernel ".config" file.  It will be
selected automatically based on the Processor selected for kernel
compilation.

If you don't have this line in ".config" then one should configure the
Xenomai as
-----------------------------------
./configure --disable-tsc
-----------------------------------

When CONFIG_X86_TSC is available in kernel then on "./configure" will work
for Xenomai.

Thanks.
