I have a Sequoia board (440EPx) with kernel 2.6.27.9. I've recently
plugged in a PLX adapter board to convert one of the PCI connectors
on the Sequoia to PCIe.
When the kernel boots, I get the following error messages regarding
mem resource allocation. Device 0000:00:0c.0 is the PCI<->PCIe bridge,
and device 0000:01:00.0 is an FPGA PCIe evaluation board.
PCI host bridge /plb/pci@1ec000000 (primary) ranges:

Plain PCI cards plugged directly into the Sequoia work fine. Is there
something I have to add to the .dts file to represent the PCI<->PCIe
bridge?
Thanks,
Steve

Please enable DEBUG in arch/powerpc/kernel/pci-common.c and pci_32.c and
send us a full log. It might also be useful to do that on top of 2.6.28
in case some of the changes that went in after .27 make a difference.
I think I'll turn those DEBUG into something that can be enabled from
the kernel command line one of these days :-)
Cheers,
Ben.

Here is a complete startup log, with debug turned on as you requested.
This is still against 2.6.27.9, as it will take me a little time to
build 2.6.28. Hopefully, this log will be useful in the meantime.

I've repeated the experiment with 2.6.28. There is no improvement; I'm
still getting the "can't allocate mem resource" messages.
I've included the log below, with debug turned on in the specific pci
files you mentioned, and with the debug flag passed to the kernel. At
the end of the log, I did an lspci, and also looked at /sys/bus/pci.
As you will see, the resources are all zero.
I can also try again with one of the "master" or "next" trees. If you
think that would be helpful, just let me know what tree you would like
me to try.
Thanks again for helping with this.
Steve

I saw a recent post from Anton talking about U-Boot configuring PCI. That
got me wondering if U-Boot has anything to do with the problem I've
reported. So, I turned on debug in uboot's pci_auto.c, and added another
DEBUGF like so:
if (addr - res->bus_start + size > res->size) {
DEBUGF("address=0x%lx bus_start=%lx size=%x limit=%lx\n",
addr, res->bus_start, size, res->size);
DEBUGF("No room in resource");
goto error;
}
When starting U-Boot, I get a "No room in resource" message. Will this
affect Linux, or is it just a U-Boot warning?

Time to answer my own questions. U-boot is missing a setting for
CFG_PCI_MEMSIZE in the sequoia.h file. Four 256MB TLBs are reserved,
but since CFG_PCI_MEMSIZE is not set, the size defaults to 256MB,
rather than the 1GB that is allocated.
So, I added:
#define CFG_PCI_MEMSIZE 0x40000000 /* 1GB */
to sequoia.h. Now U-boot uses all four TLBs, and that error message
goes away.
But this has no effect on Linux. So, I also changed the sequoia.dts
to make the outbound range larger, and now Linux is happy too. I now
have ranges for the device:
# cat 0000:01:00.0/resource
0x0000000190000000 0x000000019007ffff 0x0000000000020200
0x0000000180000000 0x000000018fffffff 0x0000000000020200

So your problem is fixed ? I didn't have a chance yet to look at your
logs, but it could just have been that you didn't have enough space
allocated to PCI for your card...
Cheers,
Ben.

That appears to be the problem. Apparently the PCI/PCIe bridge requests
in excess of 256 MB of space, but the default in the sequoia .dts file is
"only" for 256 MB, so the request fails.
I'm not sure if this should be changed in the mainline. This card works
out of the box when used with a generic x86 PC, but not when used with
a sequoia. But, maybe it's just me climbing the PPC learning curve.

Nah, I think 256M is ridiculously small :-) I think the .dts for that
board should be changed, there is plenty of physical address space
available on those chips since it's using a 36-bit bus.
Cheers,
Ben.

Sheepish grin: I did more checking, and the current mainline actually has
this set to 1 GB.
The .dts I'm using dates back to 2.6.25. I had started modifying it for some
custom peripherals we have hacked onto a Sequoia, and I missed the changes
that were made between .25 and .28.
If you think 1 GB is a suitable default, then no further changes are needed.
If you think it should be bigger than 1 GB, then I could submit a patch.

Depends how many PCI busses thing thing have... 1GB should get most
people going tho.
