I'm using polling mechanism and not interrupts in my driver. Although I'm
not using polling I see strange behavior When I do lspci -v I don't see any
interrupts being allocated to PCI device behind PCI bridge !!!! But when I use
same card directly on primary bus I do see interrupt being allocated to PCI
device. Any advise why IRQ's being not allocated in case its attached
to PCI bridge ?</FONT></DIV>

Do I need to take care of any extra configuration in case of PCI card is
attached to PCI bridge ?</FONT></DIV>

<DIV dir=ltr><FONT face=Arial color=#000000 size=2>Yaa you are correct I
shouldn't use CONFIG_85xx_PCI2</FONT></DIV>

<P><FONT size=2>Rajan> I have
written PCI driver which works fine along with<BR>MPC8347 and two
PCI<BR>Rajan> card connected in a single PCI bus. When I try to
communicate<BR>same PCI card<BR>Rajan> using PCI bridge ( PCI2050B ), Linux
does detect PCI card on<BR>Secondary bus<BR>Rajan> but same driver doesn't
work !!!!<BR><BR>PCI interrupt for secondary bus set up
properly?<BR> <BR>Rajan>
Do I need to enable support for second PCI host controller<BR>at kernel level
to<BR>Rajan>make it work? Or I need to do something else ? I tried
compiling<BR>PPC-linux kernel<BR>Rajan> after enabling CONFIG_85xx_PCI2
kernel doesn't compile it gives<BR>me error while<BR>Rajan>compiling
"arch/ppc/syslib/ppc83xx_setup.c" Kernel version I'm<BR>using is
2.6.13.<BR><BR>Why you enable CONFIG_85xx_PCI2 in kernel? It is for 85xx, but
you are<BR>using 8347
