I just tried to submit this on bugzilla, but couldn't: kept getting
interal server errors. I'll try again later. For now, has anyone seen
anything like this? This is with kernel-smp-2.4.21.0.13mdk-1-1mdk.
IO-APIC is enabled on my system, however all interrupts are routed to
CPU0. This didn't used to be the case, and I see a *drastic*
performance hit because of this (for instance, using mencoder to
capture real-time TV I used to get 35fps, now I can't even get 20fps).
However, if I reset all the /proc/irq/x/smp_affinity's, interrupts
immediately begin being routed to both CPUs as they should.
Before doing anything special on boot:
$ cat /proc/interrupts

$ cat /proc/irq/0/smp_affinity
ffffffff
This indicates that the irq's should be shared... but it's not happening
unless I write something to smp_affinity.
$ echo 3 > /proc/irq/0/smp_affinity
(repeated for each /proc/irq/[0 .. 15]/smp_affinity)
(this actually works as expected if I write 1 (only goes to CPU0) or 2
(only goes to CPU1) or f or ffffffff (shares properly); it seems to be
the *writing* that wakes it up and makes it work =)
