Hi Dave,

Looking, thanks for the report and sorry for the inconvenience.

Here's the dmesg diff that looks relevant to me:

-pci_bus 0000:00: root bus resource [io  0x0000-0x0cf7]
-pci_bus 0000:00: root bus resource [io  0x0d00-0xffff]
-pci_bus 0000:00: root bus resource [mem 0x000a0000-0x000bffff]
-pci_bus 0000:00: root bus resource [mem 0x000c0000-0x000dffff]
-pci_bus 0000:00: root bus resource [mem 0xfed40000-0xfed44fff]
-pci_bus 0000:00: root bus resource [mem 0x7ff00000-0xfebfffff]
+pci_bus 0000:00: root bus resource [io  0x0cf8-0x0cff]
+pci_bus 0000:00: root bus resource [io  0x0000-0x0cf7 window]
+pci_bus 0000:00: root bus resource [io  0x0d00-0xffff window]
+pci_bus 0000:00: root bus resource [mem 0x000a0000-0x000bffff window]
+pci_bus 0000:00: root bus resource [mem 0x000c0000-0x000dffff window]
+pci_bus 0000:00: root bus resource [mem 0xfed40000-0xfed44fff window]

What's interesting is:

* v3.19 ignored [io  0x0cf8-0x0cff], but v4.0 includes it.  I think
it's wrong to include it because that's the configuration space
address/data registers, so it's consumed by the host bridge and not
produced on the downstream side.

* v3.19 includes [mem 0x7ff00000-0xfebfffff], but v4.0 does not.  This
is what's screwing up the devices.

I think all the windows should be marked as ACPI_PRODUCER in _CRS
since the space is "produced" on the downstream side of the bridge.
The [io  0x0cf8-0x0cff] region should probably be marked
ACPI_CONSUMER, and maybe that accounts for why v3.19 ignores it.  But
I haven't found the code that does that yet.

I suspect this is all related to the ACPI resource parsing rework.  I
looked through that briefly, but no issues jumped out at me, so this
is just a heads-up in case it is obvious to you guys.

Dave, it'd be useful if you could collect an acpidump so we can look
at the _CRS data in more detail.

acpidump fails here with a /dev/mem warning in the kernel,

now I'm not near the machine again until next week most likely, so I
only have ssh for now,
and the kernel it is running for which I don't have the source anymore!

is there any of tables from /sys I can grab instead?

Dave.

Also I'm wondering if reverting commit 2ea3d266bab3 (ACPI: Translate
resource into master side address for bridge window resources) makes
any difference?

Hi,

I have the same problem with a Asrock Q1900B-ITX mainboard with 
a Intel Celeron J1900 onboard.

I did a bisect and ended up with:

593669c2ac0fe18baee04a3cd5539a148aa48574 is the first bad commit

commit 593669c2ac0fe18baee04a3cd5539a148aa48574
Author: Jiang Liu <jiang.liu@linux.intel.com>
Date:   Thu Feb 5 13:44:46 2015 +0800

     x86/PCI/ACPI: Use common ACPI resource interfaces to simplify 
implementation


I can revert this quite big commit on current git head (4f671fe) with no 
problems and then everything is fine again.



       Thomas

Thanks for nailing this one!

It really wasn't supposed to make any functional difference, though, so there
must be some subtle mistake that escaped everyone in it.

I'll have a look at that and hopefully Jiang Liu will be able to help in the
meantime too.

Hi all,
	Sorry for slow response, just return from Chinese New Holidays:)
Hi Thomas,
	Could you please help to provide the dmesgs before and after the
revert?
Thanks!

just grab a Minnowboard Max and test this by yourself. It has the same problem. The MAC address is ff:ff:ff:ff:ff:ff with this patch. Once I reverted it, the MAC address is correctly read again.

Marcel

Hi Marcel,
	I have no access to any Minnowboard Max board, so couldn't test
it by myself. Could you please help to forward the two dmesg files you
have sent to Bjorn in the original email?
Thanks!

Hi Thomas,
	I still can't figure out why the last resource entry "pci_bus
0000:00: root bus resource [mem 0x80000000-0xd0716ffe]" gets ignored
by new code. Could you please help to apply these two patches and send
me back dmesg?
Thanks!
Gerry

When parsing resources for PCI host bridge, we should ignore resources
consumed by host bridge itself and only report window resources available
to child PCI busses.

Hi Bjorn,
	We should ignore resources occupied by host bridge itself.
Will work out a patch to fix this issue.

I need more information to figure out why resource [mem
0x7ff00000-0xfebfffff] is ignored by new ACPI parser.
Could you please help to forward the original dmesg attachments?
Regards!

Hi Thomas,
	According to the dmesg, it seems that BIOS reports malformed
ACPI resource descriptors. The new code enforces stricter checks for
ACPI resource descriptors, so it skips some malformed ACPI resource
descriptors. Could you please to try this two patches again?
Thanks!
Gerry

Commit 593669c2ac0f (x86/PCI/ACPI: Use common ACPI resource interfaces
to simplify implementation) causes regression to several platforms,
which is caused by stricter checks in new ACPI resource parsing code
and BIOSes report incorrect ACPI resource descriptors.  So try to relax
the check to avoid regressions.
