<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I have a framebuffer driver for the
Fujitsu CoralP that registers fine with the PCI bus and operates for my new arch=powerpc
2.6.24 build. The only thing that failed when jumping from arch=ppc on my
2.6.16 kernel to my new 2.6.24 kernel is the interrupt request. While testing
other functionality I simply compiled-out the interrupt request because it is
not always critical for basic frame buffer operation. I’m back to wanting
the interrupt.<o:p></o:p></span></font></p>

board in both cases (2.6.14 and 2.6.24 kernels). Under the old ppc scheme I obtained

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Under my new powerpc kernel 2.6.24 I
obtain irq=0 and the subsequent interrupt request fails. Also, a hard-coded
irq=1 fails too. I know this is an issue with NOT querying the device tree, but
I’m not sure what to specify in lite5200b.dts, or what property I need to
query to get the correct pci interrupt.<o:p></o:p></span></font></p>

is all the info I need already in there, or do I need to add my pci device? I’ve
done some mucking around in the dts file but I’m not a pci expert so I am
a bit confused.<o:p></o:p></span></font></p>
