IRQ splitting

[Jan Engelhardt]

Hello list,



let's take the following /proc/interrupts dump (CPU2,CPU3 trimmed)...

           CPU0       CPU1
  0:   37041766   37038991  IO-APIC-edge  timer
  1:         10          2  IO-APIC-edge  i8042
  8:          0          0  IO-APIC-edge  rtc
  9:          0          0  IO-APIC-level  acpi
 12:        114          0  IO-APIC-edge  i8042
 14:      25219    5800049  IO-APIC-edge  ide0
201:     260381     238454  IO-APIC-level  aacraid
209:          0          0  IO-APIC-level  ohci_hcd:usb1
217:          0          0  IO-APIC-level  ehci_hcd:usb2
225:   57531742          0  IO-APIC-level  eth0,radeon@pci:0000:03:00.0
233:         26          0  IO-APIC-level  eth1
NMI:       1661       1397
LOC:  147579966  147579949
ERR:          0
MIS:          0

My question is whether it is possible that eth0's interrupts go to CPU0
and radeon's to CPU1, and if so, how I would enable that. Alternatively,
is it possible to just move eth0 or radeon to a different interrupt?
