Title: Xbox Irqls (interrupt Request Levels)?
Post by: _zlinky on August 27, 2007, 12:32:00 AM
Hey, does anybody have a list of all of the Xbox's IRQLs?  A list similar to this?

http://en.wikipedia....terrupt_request (x86 IRQs)

Are the PC's and Xbox's IRQLs the same?  Thanks.

If I remember well (you can see that in src/hal, in openxdk source files)

Irq 1 = USB (see input.c)
Irq 2 = Hard disk? (pure guess, unused by openxdk I think)
Irq 3 = GPU (see video.c, also pbKit will override openxdk's control over it)
Irq 4 = Network (see pktdrv.c, xbox1 network driver for openxdk)
Irq 5 = Sound? (I don't remember well, unused so far in openxdk -chat?-)
Irq 6 = Sound (see audio.c)


Alright, that sheds alot more light on things,  thanks alot.  I'm sure with a little more work I could find out the unknowns.
