Hi,
thank you for your message. I find it VERY usefull! I have many
questions:
1-- Keep in mind that I need the processor for a period of 100
milisecond ONLY. After that, my process can be off for 10 seconds or
more... Between the 'critical sections', there is p
Alain, I think I got a personal mail from you, but I deleted it before I

Could you resend it on the list?

Depends. Here[tm] it's still just about 100 I/O-cycles.

Basically, for x86 the "cli" and "sti" asm instructions do disable/
enable interrupts, but read about it before you try.
Currently, I do such stuff only inside a driv

Well, 200 ms is abo
Hi,
would someone know how to execute: spin_lock spin_lock_init and
spin_unlock
I just want to disable the interrupts for 200 miliseconds maximum! This
is not too long and hopefuly, my system will not crash...
Does someone has any experience with this kind of situation.
