Reassigning IRQs?

Storm16 · 05-26-2006, 10:29 PM

1.2 GHz Athlon on a DFI AM75 mainboard, I have what appears to be too many devices on IRQ 5:

Code:

           CPU0       
  0:    1858309          XT-PIC  timer
  1:         40          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  5:     214270          XT-PIC  uhci_hcd:usb1, uhci_hcd:usb2, Bt87x audio, bttv0
  7:          2          XT-PIC  parport0
  8:          4          XT-PIC  rtc
 10:     645510          XT-PIC  ESS Maestro, nvidia
 11:       5940          XT-PIC  acpi, eth0
 12:       5402          XT-PIC  i8042
 14:      67093          XT-PIC  ide0
 15:      17187          XT-PIC  ide1
NMI:          0 
LOC:          0 
ERR:          0
MIS:          0

It is affecting video and audio processes when polling the printer. There does not appear to be a way to force an IRQ in bios (the only option is to use an IRQ or not), is there a way to do so in Linux?

Thanks,

Not sure if the bios supports it but maybe you can define IRQ as a Legacy ISA and then it might redistrubute the others.
