Hi All,
Is there any synchronization calls like semaphore/mutex for the real
time threads ? . I could n't find anything related to synchronization in
the listed RT-Linux API's.
Thanks in advance!!

Mani.

What's the details of the crash? Is it repeatable?

I think that there are ways of adding new entries to the list in

Hi!
Programming a DA-Converter I have a time sorted linked list in which output
values and corresponding times are stored.
A realtime-Thread released via the one shot timer outputs the
entries of this list at their according time and removes the entries from
the list.

Within Simulink -as I remember-
I found, that too many rtl_printf() within a short period
can crash the kernel.
Why?
Is there any automatic mechanism to prevent this?
I have a 19200 bps serial console on a 100MHz 486 machine.
RTL version is 2.2.
CONFIG_RTL_SLOW_CONSOLE=y
