Re: [Xenomai-core] posix: only use rt_printf when in primary mode
Hi Gilles, dynamic printf backend selection is a suboptimal idea when you want chronological output (not that uncommon during debugging). The native printf may actually hit the screen (or the log file) before some earlier queued rt_printf message because the dump thread is busy or has a lower priority. It's ok to do native printf for non-shadows. But once a thread was mapped, printf needs to go through the rt queue, even in secondary mode.

Oh, I missed the buffer flush - that should work. Sorry for the noise.

It does that without issuing a warning message if the check fails - in contrast to do_hisyscall_event. As user space may call this cleanup service even for non-shadow threads (e.g. after shadow creation failed), we better silence this warning. Signed-off-by: Jan Kiszka jan.kis...@siemens.com Jan, I have a branch here, which allocates u_mode in the shared heap, so, this syscall is about to become unnecessary.
