[ath9k-devel] PCI IRQ Pins

[Karl Hiramoto <karl@hiramoto.org>]

Hi,

I'm using wireless testing with a mini-pci AR5416 on an arm xscale 
ixp4xx.  It seems the IRQ always comes on IRQ Pin A.     Is there a way 
to force the atheros AR5416 to use Pin B of the mini-pci?  I don't have 
access to a AR5416 datasheet to actually know if the chip has more than 
one IRQ line.  I'm not sure if this is possible to do in PCI or the 
kernel either.

This Pin A line is shared with a IDE htp371N chip which only has one IRQ 
line.  Sometimes (randomly) during boot i get the "IRQ X  Nobody cared" 
message.   This usually happens right when the BLK_DEV_HPT366  or  ath9k 
driver is loaded.


There seems to be some kind of race.  If I have both the AR5416 and 
HPT371N, loaded, and after the board has booted(everything is 
configured), the "IRQ X  Nobody cared" never occurs.   If i remove 
AR5416 mini-pci,  I also never get the "IRQ X  Nobody cared".

Thanks..
