Re: [Mesa3d-users] mach64 kernel modules for 2.6.29 WORKS but...

[c3kkos <c3...@ho...>]

I know i'm filling up your mailboxes but this is now n open challenge for me.

Here i have cat'ed my /proc/interrupts:

           CPU0       
  0:      11869    XT-PIC-XT        timer

----------------------------------------------------------

it's now clear that i'm facing a irq problem. indeed the drm module does not
like sharing the bus with
the audio data trunks. I think trying to have a different pci latency
timings setup is a waste of time. The bios does not have any option to
manipulate the plug-n-play system..

IRQ 5 is bound to the SOLO-1 at boot time and is bound again to the
drm/mach64 when xorg load up his modules.

I've to find out how i can modify the solo-1 irq assignment via software..
cause the other way is the old "jumpers way" but since i'm using a
notebook.. i can hardly think there're some upon my hardware..

any suggestions? i've looked for a script set called rtirq that maybe can be
useful but it can be used, as the name already tells, with the real-time
kernels..

Ahuuuuuu!!!!!!!!
