Subject: [Xenomai-help] Detecting switch to secondary mode
Date: Thu, 6 Jul 2006 13:43:51 +0200	[thread overview]
Message-ID: <20060706134351.2e582664@domain.hid> (raw)

Hello,

I have written a xenomai application (posix-skin) with several tasks. All of them should normally use primary mode (SCHED_FIFO). While some are allowed to switch to secondary mode for stuff like I/O and memory allocation others must not switch due to hard realtime constraints. 

Is there a way to check if and how often a thread has switched to secondary mode and maybe even what system call caused the switch? While a test from within the program itself would be great some information from /proc/xenomai would also do.

Thanks,
	Jens
