Hello RTers
I did not get a response to this question a few days ago so I
thought I would try again. Is RTAI or RTLinux being run on
handheld PCs. If so which handhelds are best suited for RT
applications (Yopy, Compaq, etc)?
Also does anyone have a good link to

On an x86 (for example), if an RT task programs a clock timer does it

Looking at some of the examples, it appears that an RT interrupt handler
can invoke the RT scheduler (by calling pthread_wakeup_np, sem_post,
etc). And it looks like the scheduler is going to swap in a runnable
task when this happens.
This doesn't seem safe... I'm still thinking about it...

Hi,
I've been looking over the kernel patch and the rtl module code trying
to figure out what needs to be done for an ARM port. I've been focusing
on the 2.4 version where the patch is concerned. I'm using rev 3 of RTL.
I have some questions.
A. Does the MIPS version really work?
