What is XT-PIC-XT???

webquinty · 07-27-2011, 08:07 AM

Hello,

Install my kernel in a new board, 2.6.24.7-rt26 and now I would like to setup a irq as rise or fall trigger.

Then, I have created a kernel driver to request a irq but return me a error or message:

Why can not setup IRQF_TRIGGER in my irqs??

What is the difference between XT-PIC-XT and IO-APIC-EDGE?

best regards

Different hardware designs use different interrupt controllers. My understanding is that PIC is the older of the two.

"Use the Source, Luke!" The best way to resolve questions like these, other than "Google It," is to grep the kernel source-tree looking for message fragments.

Yes, you are right.
I have downloaded specifications of interrupt controller of my board (8259A) and it is possible to setup positive edge or positive level, but no more.
The new interrupt controller is better, because it has more options to setup, like positive or negative edge, etc etc.

Thank you very much.
