Subject: no map ! Using irq line 0 from PCI config
Date: Thu, 28 Sep 2006 15:53:47 -0500 [thread overview]
Message-ID: <451C365B.8090300@freescale.com> (raw)
I'm having a problem with a SATA PCI device on an 8349E board. The SATA driver is timing out when trying to query the drive. I believe this is happening because interrupts aren't being routed correctly.
My assumption is that there's something wrong with my DTS file. Unfortunately, despite pouring over document and code all week, I really don't understand how the interrupt-type stuff in the DTS file is supposed to work. Is there anyone on this list who can help me?
When I boot my kernel with the debug messages, I get this output:
Found MPC83xx PCI host bridge at 0x00000000e0008500. Firmware bus number: 0->0

The SATA controller (SIL 3114) is the only device on PCI 1.
Here's my DTS file. I think the problem is in the interrupt-map section of pci@8500"
