[Bjorn: I stuck your name in the "To" list as Jesse told me that you
know all about this code]
My shiniest, newest, ia64 development system used to work fine. But
in 2.6.31 the USB keyboard and mouse on the console stopped working.
Console log sprouted a new error message:
ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
ehci_hcd 0000:00:1a.7: device not available because of BAR 0 [0x58328000-0x583283ff] collisions
ehci_hcd 0000:00:1d.7: device not available because of BAR 0 [0x58324000-0x583243ff] collisions
which explains why USB is broken. Somebody bisected the .30 to .31 transition
and found this commit as the culprit:

commit 1d89b30cc9be41af87881682ec82e2c107849dbe

ia64: Fix resource assignment for root busses
ia64 was assigning resources to root busses after allocations had
been made for child busses. Calling pcibios_setup_root_windows() from
pcibios_fixup_bus() solves this problem by assigning the resources to
the root bus before child busses are scanned.
--------------------------------------------------------------------------
and indeed reverting that patch from the latest kernels does get
rid of the ehci messages, and the USB keyboard/mouse work again.
BUT ... with the patch reverted I lose some other devices:
ata_piix 0000:00:1f.2: version 2.13
ata_piix 0000:00:1f.2: device not available because of BAR 0 [0x4138-0x413f] collisions

ata_piix: probe of 0000:00:1f.5 failed with error -22
and also:

uhci_hcd 0000:00:1d.2: device not available because of BAR 4 [0x4020-0x403f] collisions
some more bisection showed that this followup commit is responsible
for not allowing the reversion of willy's commit to fix things:

commit 79896cf42f6a96d7e14f2dc3473443d68d74031d
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date: Sun Aug 2 14:04:19 2009 -0700
Make pci_claim_resource() use request_resource() rather than insert_resource()
This function has traditionally used "insert_resource()", because before
commit cebd78a8c5 ("Fix pci_claim_resource") it used to just insert the
resource into whatever root resource tree that was indicated by
"pcibios_select_root()".
So there Matthew fixed it to actually look up the proper parent
resource, which means that now it's actively wrong to then traverse the
resource tree any more: we already know exactly where the new resource
should go.
And when we then did commit a76117dfd6 ("x86: Use pci_claim_resource"),
which changed the x86 PCI code from the open-coded
pr = pci_find_parent_resource(dev, r);
if (!pr || request_resource(pr, r) < 0) {
to using
if (pci_claim_resource(dev, idx) < 0) {
that "insert_resource()" now suddenly became a problem, and causes a
regression covered by
http://bugzilla.kernel.org/show_bug.cgi?id\x13891
which this fixes.
--------------------------------------------------------------------------
The code now appears to walk ACPI looking for _CRS methods to find out
which resources are attached to which busses. When drivers are paired
up with devices later, we check to make sure that the device has a
correct parent. For my system this seems to fail because the _CRS walk
only turns up some IO resources and no MEM resources. So the echi
(which wants mem 0x58328000 and mem 0x58324000) is out of luck and
denied.
Here's some output showing what _CRS found:
ACPI: PCI Root Bridge [PCI0] (0000:00)
pci_acpi_scan_root: allocated controller e000000303340b00 <<<< my debug printk
Count of _CRS items for this controller = 2 <<<< my debug printk
pci_root PNP0A08:00: host bridge window [io 0x0000-0x0cf7]
pci_root PNP0A08:00: host bridge window [io 0x1000-0x8fff]
Walked _CRS and assigned 2 windows for 'PCI Bus 0000:00' <<<< my debug printk
and
ACPI: PCI Root Bridge [PCI1] (0000:80)
pci_acpi_scan_root: allocated controller e000000303343380 <<<< my debug printk
Count of _CRS items for this controller = 1 <<<< my debug printk
pci_root PNP0A08:01: host bridge window [io 0x9000-0xfffe]
Walked _CRS and assigned 1 windows for 'PCI Bus 0000:80' <<<< my debug printk
Is this a correct understanding of what the Linux pci code now expects
to find? Which bit of the ACPI spec should I use to beat the BIOS
engineers over the head to point out the error of their ways?
Are there some options for a quirk, or some other workaround to get my
system up and running on latest kernels (since I'm sure that getting
a fix to the BIOS will be a long, slow process)?

On ia64, we've always used _CRS to find the resources for host bridges
(though we only recently started printing out the windows), and PCI
has always relied on what we find. But if we only find I/O port
ranges, something is seriously wrong.
It's possible we're seeing something new in _CRS that we don't handle
correctly, e.g., maybe resource_to_window() is incorrectly rejecting
something.
I'd start with a patch like this (just the rsutils.c piece):
http://bugzilla.kernel.org/attachment.cgi?id\x16776
If you can post the output with that patch, we can manually decode the
_CRS buffer straight from ACPI, so we can at least figure out whether
to look at Linux or the BIOS.
If this is really a BIOS issue, I would expect Windows to fail
miserably as well.

Here's the dmesg output with that patch applied (rsutils.c has been
moved since that patch was written - I applied the hunk to the new
location: drivers/acpi/acpica/rsutils.c)

I don't see the connection between the commits you identified and
the fact that we don't find any host bridge memory windows.
The problem I see is that the PNP0A08:00 host bridge has a bunch
of memory resources that are marked as "Consumer," which means the
bridge doesn't forward those regions downstream. It's normal for
a bridge to have a couple things like that, e.g., 0xcf8, which the
bridge consumes and turns into config space accesses downstream,
but most of these are huge regions that are obviously supposed to
be Producer, not Consumer.
That would certainly explain why the downstream devices don't work,
but it doesn't explain why they worked prior to 2.6.31. We've been
checking that Producer/Consumer bit since 463eb297401e in 2005.
Are you sure there wasn't a BIOS change at the time things broke?
I guess if you bisected it, there shouldn't be a BIOS change in the
middle, but I just don't see how this could ever have worked with
the _CRS we're getting from the BIOS.

Byte 4 (0x0d) has bit 0 set, which means this device consumes this
range but does not produce it, i.e., the device (the host bridge)
responds to this region but does not forward transactions to any
downstream devices. This is in Table 6-42 of the ACPI 4.0 spec.
In the two WORD I/O descriptors preceeding this, bit 0 of byte 4
is clear, which means the bridge *does* forward that range downstream.
resource_to_window() ignores consumer-only resources, which explains
why we aren't treating these memory descriptors as host bridge windows.

Bjorn,
Thanks for the help on this. There was a BIOS change, but I don't
think that it is connected to this. I don't have any old boot logs from
the old BIOS, but I can definitely build & boot old kernels like
2.6.29 on the new BIOS and see all the devices.
One theory for how old kernels managed to work is that when
pci_create_bus() is called it initially sets resource[0] to map
all possible IO space, and resource[1] to map all MEM space.
In the current kernel these get overwritten with the actual
windows before we do anything with them. But perhaps in
the old kernel (before Willy changed the ordering) we might
have accepted by ehci devices while the bus apparently mapped
everything?

I commented out that check in resource_to_window() ... and
my system booted with a lot more windows reported, and
all the devices working. So a good theory for what is wrong
is that the BIOS has all the right windows listed in _CRS, but
it just has the wrong flags on some/all of them. But in particular
this one:

I'll see if I can find the BIOS people for this platform and ask
them if they can change the 'd' to a 'c'.

Maybe so. All HP ia64 boxes have multiple host bridges, so it
seems like using those default IO and MEM resources would have
broken any Linux resource assignments, like for hotplug and option
ROM mapping. But those haven't been tested very much, so maybe we
just didn't notice. Anyway, I don't have a better idea.

I would expect the incorrect flags to break Windows as well.
HP host bridges are ACPI devices, not PCI devices, and they have
both consumer resources (for configuration of the host bridge
device itself) and producer resources (windows that are forwarded
downstream). If we ignored the flag, we'd treat those bridge
configuration resources as windows, which would be wrong.
