Hello
I'm using xenomai in a qemu setup.
My final goal is to use xenomai to port extisting pSOS application to the
linux platform.
The first step I did was building a kernel with the pSOS skin enabled. These
traces are generated at kernel startup:
[ 0.212363] I-pipe: Domain Xenomai registered.
[ 0.212363] Xenomai: hal/i386 started.
[ 0.212363] Xenomai: scheduling class idle registered.
[ 0.212363] Xenomai: scheduling class rt registered.
[ 0.246987] Xenomai: real-time nucleus v2.5.4 (Sleep Walk) loaded.
[ 0.246987] Xenomai: debug mode enabled.
[ 0.274658] Xenomai: starting native API services.
[ 0.274658] Xenomai: starting POSIX services.
[ 0.296357] Xenomai: starting RTDM services.
[ 0.296357] Xenomai: registered exported object RN#0 (regions)
[ 0.296357] Xenomai: starting pSOS+ services.
[ 0.305601] HugeTLB registered 4 MB page size, pre-allocated 0 pages
This is the example application:
#include <psos+/psos.h>
void task2_func(u_long a,u_long b,u_long c,u_long d)
{
while (1) {
tm_wkafter(1000);
}
}
int main(int argc, char **argv)
{
unsigned long tid;
unsigned long args[4] = {0,0,0,0};
t_create("TEST",10,160000,160000,0,&tid);
t_start(tid,0,task2_func,args);
while (1) {
sleep(100);
}
}
The command line used during compilation is:
/home/meeusr/repo/xenomai-configs/buildroot-output/staging/usr/bin/i686-unknown-linux-uclibc-gcc
-Os -pipe -Os -mtune=i686 -march=i686 -D_LARGEFILE_SOURCE

-lxenomai -lpthread -lpsos -Xlinker -rpath -Xlinker
/home/meeusr/repo/xenomai-configs/buildroot-output/target/usr/xenomai/lib
-lrtdk -o rtprint_ronny
When I try to run the application I get (first time):
# ./rtprint_ronny
Xenomai pSOS skin init: t_shadow() failed, status -14#
#
The second time I get
# ./rtprint_ronny
[ 145.049826] Xenomai: FAILED to register object MAIN (unknown type),
status -17
Xenomai pSOS skin init: t_shadow() failed, status -17#
#
I already read somewhere that the -14 and -17 error codes (negative values)
indicate that there is a problem in the nucleus
Can somebody tell me what I do wrong?
Best regards,
Ronny

I'm unsure whether the code above is actually the one which issues the
output mentioned below. I see no t_shadow call, and no status printout
there.

Assuming your code does call t_shadow, the behavior you see is caused by
a regression in the pSOS skin. Please apply:
http://git.xenomai.org/?p=xenomai-rpm.git;a=commit;h=55c1b958c6bd11068cacb6258c7a957ab581ce73

> #
This was a consequence of the previous bug; the shadowing call would
raise a fault causing the calling task to die, but the cleanup code
could not run as expected, leaving a stale "MAIN" task entry in the
internal registry. This would in turn cause -EEXIST to be sent for any
attempt to create a "MAIN"-labeled task again. The patch mentioned above
should prevent this situation to occur.

Nothing. The pSOS emulator code was wrong.

Maybe the auto-shadowing of the main thread?

Correct. I did not recall we had auto-shadowing in place for pSOS
actually.

After applying the patch the problem is resolved.
Thank you very much for the quick support.
Best regards,
