I am glad to hear from you.
Thank you for your prompt reply.
It does not work well.
For detials, see below.
~/linux-4.9.38$ grep -nr COBALT | grep sched_yield
kernel/xenomai/posix/syscall_entries.h:38:
__COBALT_CALL_ENTRY(sched_yield) \
kernel/xenomai/posix/syscall_entries.h:137:
__COBALT_MODE(sched_yield, primary) \
~/linux-4.9.38$ #log ends
I have found some clue in the comments at
xenomai-3.1/kernel/cobalt/posix/syscall.c.
For your convinence, the comments mentioned above is listed in this
email.
As the last email shows, I could not loate the right source code
either while grep for cobalt_sched_yield .
/* sc_cobalt_sched_yield - which do not require any thunk -
* would also appear twice, but both entries would point at the native
* syscall implementation:
*
* [sc_cobalt_sched_yield] = cobalt_sched_yield,*/
Best regards.
