[Greg K-H suggested I distribute this more widely]

Hello all,

there appear to be difficulties correctly mapping addresses behind a
PCI Express-to-PCI bridge in kernel 2.6.12-rc5.

Specifically, this occurs on my Acer Travelmate 8100 notebook (Pentium
M, Intel 915M chipset) when it is connected via PCI Express to the
ezDock docking station.

While all of the USB and FireWire devices are visible using config
space reads, they cannot be accessed correctly (all normal reads
appear to return 0xff). After checking the dmesg logs, I find

PCI: Cannot allocate resource region 7 of bridge 0000:02:00.0
PCI: Cannot allocate resource region 8 of bridge 0000:02:00.0

This would confirm my hypothesis, since reads go the route of

Processor
Intel 82801xx ICH6 southbridge
PCI Express port 3 0000:00:1c.2
Intel 6702PXH PCIE-PCI bridge 0000:02:00.0
ezDock-internal PCI bus 0000:03:xx.x
USB
Firewire
...

Since the PCIE-PCI bridge cannot be memory-mapped, the devices behind it
cannot be accessed correctly.

I am no expert on debugging this part of the kernel, but I will gladly
provide additional info to resolve this problem.

For your reference, I have attached a dmesg log with PCI debugging info,
two lspci outputs (-vvt and -vvx), and a dump of /proc/iomem.

Many thanks,
Andreas Koch

Well, that would be right, because the parent of that bridge doesn't seem
to have any resources set up:

0000:00:1c.2 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 3 (rev 04) (prog-if 00 [Normal decode])

Prefetchable memory behind bridge: 0000000000000000-0000000000000000

the "IO/memory behind bridge" things don't seem to be making a lot of
sense.

Hmm. Normally on PC's we let the BIOS worry about PCI bridge resource
setup. The hotplug code knows about the setup-bus stuff too, but the
_normal_ PCI bus resouces are usually left alone. It looks like maybe we
shouldn't do that any more for PCI Express.

Hmm.. Just a wild guess (and this may not work at _all_, so who knows..):
how about adding a

pci_assign_unassigned_resources();

call to the end of "pcibios_init()" in arch/i386/pci/common.c ?

NOTE! In order for that to even link, you need to make sure that you have
CONFIG_HOTPLUG enabled, otherwise x86 won't have even linked in the bus
resource code from drivers/pci/setup-bus.c. And even so, I won't guarantee
that it does anything sane...

(I'm really surprised that we've gone this long without havign x86 do the
bus setup, though. So I'd not be in the least surprised if we need
_something_ like this, I'm just not at all sure that just adding that
single line won't do something disastrously bad..)

As you suspected, it wasn't a panacea: The kernel now panics, with a
call chain of

...
pcibios_init()
pci_assign_unassigned_resources()
pci_bus_assign_resources()
pci_setup_bridge()

I can collect more specific info if necessary.

Thanks for looking into this,

It would be nice to know exactly what it is that panics, I could well
imagine that it's something like the "bus->self" that ends up being NULL
for the root bus or something silly like that, simply because x86 has
never needed to use these functions.

If so, it migth be as easy as just skipping buses that don't have bridge
device associated with them, but this would require that you try to debug
the oops a bit to figure out where it is..

Greg, do you have any PCI Express hw? Although I suspect that the
pci_assign_unassigned_resources() problem probably happens on any PC, I
could try it on my laptop.

Actually, I tried that already. But I didn't get any usable info from
the oops and GDB (`list *pci_setup_bridge+0x1a2' shows an include file,
not a line in the function) . I'll make another attempt tomorrow when
I am more awake :-)

Usually the easiest way to match up things is to just do

I do not :(

I have some motherboards with PCI Express slots, but I haven't been able
to find any Express cards around town anywhere.

Anyone have any pointers to a simple PCI express network card? (no, I
don't want a PCI express video card, although if someone wants to send
me one I will not complain...)

thanks,

Are you connecting it at boot time, or after the box is up and running?

Hm, another idea, can you load the pci express and standard pci hotplug
drivers? You might have to "enable" those slots in order for the pci
core to scan the devices and set everything up properly.

To do this, after loading the modules (pciehp and shpchp), look in
/sys/bus/pci/slots/

If there are any "slots" listed there, go into those directories and
"power them on" by simply writing a "1" to the file 'power' by using
echo.

Let us know if that helps out any or not.

Oh, and this isn't "PCI ExpressCard" type hardware is it (next
generation pcmcia/cardbus evolution.)

thanks,

"simple"? Well, I'm aware of bcm5708 and Michael Chan (Broadcom)
recently posted the bnx2 driver for it. If HP has it, then others
are likely offering it too:

The oops is because we normally don't even assign but->resource[2] for the
root bridge. The following seems to fix the oops, but it makes a normal PC
totally unbootable, so that doesn't help you. I didn't have a serial
console hooked up, so I didn't get the logs. Somebody who has, and enables
CONFIG_PCI_DEBUG, can you send me the output?

OK, here's some more info (now visible on an 80x60 FB console):

1) I can see a couple of messages

PCI: Failed to allocate mem resource #10:2000000@80000000 for 0000:06:09.1
...

followed by

PCI: Bus 7, cardbus bridge: 0000:06:09.0
IO window: 00005000-00005fff
IO window: 00006000-00006fff
PREFETCH window: 80000000-81ffffff
MEM window: 80000000-81ffffff

, repeated for busses 11 and 15 of the cardbus bridge. This is the
notebook-internal cardbus bridge (see lspci in previous mail).

2) The last messages right before the oops are

PCI: Bridge 0000:00:1e.0
IO window 1000-6fff
MEM window: 01000000-0dffffff

This is the Southbridge to the notebook-internal PCI bus 0000:06

3) The oops itself occurs when attempting to setup the PREFETCH window of
that bridge and begins

Unable to handle kernel NULL pointer dereference at virtual address 00000004

Specifically, it is located at the call of

pcibios_resource_to_bus(bridge, &region, bus->resource[2]);

in drivers/pci/setup-bus.c, line 202. I confirmed that
bus->resource[2] is indeed NULL at that time.

Interestingly, the PCI Express-to-PCI bus in the docking station
appears _not_ to be involved in this crash.

As usual, please let me know what additional info would be useful.

The dock is already connected at power-up time.

I have already experimented with compiled-in versions of these drivers
(as well as the ACPI PCI hotplug driver).

I have /sys/bus/pci/slots/, but it is empty. Should I make another
attempt with driver modules instead of the compiled in versions?

Actually, the dock itself has a PCI ExpressCard slot (currently
empty) as one of its peripherals. But my current difficulties are
with the PCI-Express connection between notebook and dock.

Indeed. From your lspci output:


0000:00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev d4) (prog-if 01 [Subtractive decode])

It's the "transparent" bridge. The code in setup-bus.c doesn't handle this
properly.

Please try this patch - it should fix two problems:
- in pci_setup_bridge() use bridge resources directly, instead of
the resource pointers in struct pci_bus (this fixes an oops);
- [ioport,iomem]_resource must not be touched in the bus setup code,
otherwise we screw up the whole resource tree.

With the patch and Linus' modifications, the boot progresses further
than with Linus' mods alone. However, it now fails a bit later when
it comes the CardBus bridge in the docking station (following output
manually typed from the console):

For your reference, at this stage we appear to have a cascade of three
bridges between a potential device (currently empty CardBus slot) and
the CPU

CPU Southbridge -> PCI Express -> PCI -> CardBus

Note that the messages before this log, e.g., from ohci1394, also indicate

Well, the problem is that bridge 1 in this chain is completely unconfigured
(it seems to be in after-reset state), while bridge 2 (PCIE-to-PCI one)
does have reasonable setup. This leads to "successful" resource allocations
on the bus 3, even though these resources are not accessible due to
incorrect setup of the bridge 1.
On the other hand, pci_assign_unassigned_resources() doesn't touch
already allocated resources, probably leaving them outside of bridge windows.

I think the correct behaviour of pcibios_allocate_bus_resources()
(arch/i386/pci/i386.c) should be as follows:
if some bridge resource cannot be allocated for whatever reason,
don't allow any child resource assignments in that range. Just
clear the resource flags - this prevents building an inconsistent
resource tree.

pci_assign_unassigned_resources() should correctly configure bridge 1
and all subordinate stuff then.

I just found the time to test your latest patch (sorry for the delay).
However, it doesn't seem to help.

First of all, I verified that your code is indeed being called. That
does occur. Specifically, resources cannot be allocated for the
following bridges and regions:

0000:00:01.0, region #10
0000:00:1c.0, regions #7,8,9,10
0000:00:1c.1, regions #7,8,9,10
0000:00:1c.2, regions #7,8,9,10
0000:02:00.0, regions #7,8,9,10
0000:03:05.0, regions #7,8,9,10
0000:00:1e.0, regions #7,8,9,10
0000:06:09.0, regions #7,8,9,10
0000:06:09.1, regions #7,8,9,10
0000:06:09.3, regions #7,8,9,10

However, after pci_assign_unassigned_resources() has been called, the
MEM and PREFETCH regions of the bridge 0000:00:1e.0 (bridge 1) _remain_
invalid at 0x00000000.

The boot hangs (as before) when attempting to start the CardBus
controller in the dock.

If you need further info, please let me know.

I believe it was _IO_ and PREFETCH (unused windows of that bridge).
Indeed, IO at 0 is fatal...

Here is additional patch which ensures unused windows of the transparent
bridge are disabled.

I haven't tried the patch yet, but had time to check the debug output
again. And for the bridge 0000:00:1e.0, it definitely lists all
_three_ characteristics (IO, MEM and PREFETCH) as zero. I'll let you
know how the patch turns out.

Hrm... IO at 0 for a P2P bridge is perfectly valid, at least on a number
of architectures... However, testing for region.end < region.start is, I
suppose correct ...

Sure, but on x86 it blocks access to VGA registers and other legacy
stuff. That's why Andreas' machine hangs, I suppose.

So, I managed to test Ivan's latest patch. The machine still hangs,
but a little bit later in the boot process.

Observations thus far:

1) After Ivan's sanity checks in pcibios_allocate_bus_resources get
executed (with the same results I described in a prior mail), I get a
number of messages stating that for the devices on
0000:03:{02,03,04,05}.x, resource regions could not be assigned.
These are the devices in the docking station (behind the PCIE-PCI bridge).

2) Later, I get messages that bogus ressources of 0000:00:1e.0 are ignored

3) Then, the output of pci_setup_bus_bridge begins. It indicates that
for the bridges 0000:00:1c.0, 1c.1 and 1e.0, the characteristics IO,
MEM and PREFETCH are disabled. This is the direct result of Ivan's
latest patch. NOTE: 0000:00:1c._2_, the bridge to the external PCIE,
_does_ appear to have valid data for IO, MEM and PREFETCH.

4) Since the messages of ohci1394 with regard to 0xff reads from the
external FireWire controller persist, I assume that the external
devices can still not be successfully memory mapped.

5) With this latest patch, the boot process proceeds beyond the attempt
of initializing the external CardBus bridge 0000:03:05.0 (which fails
as before `no PCI interrupts. Fish ...' to the initialization of the
internal CardBus bridge. After a `socket status: 3000006' and ACPI PCI
interrupt assignment messages, the machine hangs with no further output.

I regret that I cannot be more specific. But since this machine's
serial port is _on the external dock_, I cannot even provide full logs
obtained by SERIAL_CONSOLE. If you want me to look for specific things in
the output (that I can capture by inserting loop-based pauses at specific
places in in the boot process), I'll gladly do so.

I did some more experimentation, and to my great the surprise, the
serial port on the dock _is_ functioning, even when the rest of the
dock is dead. So, I managed to capture a full log using the serial
console. I sure hope that we can get to the bottom of this now :-)

I wonder whether the bridge is effectively a negative decode thing, and
the only "real" problem is that because the kernel doesn't know that, it
doesn't know that it can allocate just about any resource at all on the
other end..

It would be pretty strange, since the PCI spec (afaik, and for pretty
obvious reasons) disallows two negative bridges on the same bus (and you
already have the other mobile bridge there), but it's technically possible
if they just have different priorities for how fast they react to a PCI
address cycle and claim it.

Ivan, can you cook up some silly patch that just marks that one device
transparent, and see if that "just fixes it".

Note that, after further checking, I discovered that the very
low-speed ports on the dock (serial, PS/2, parallel) are _not_
interfaced via PCI Express (as the USB and FireWire ports are). Thus,
the fact they do work does not help us in deducing the cause of the
bridging issues.

No, I'm 99% sure it's not. Otherwise the damned thing would work without
any patches, since all devices in the dock have reasonable addresses.
It's just one bridge in the middle that hasn't.

True, especially since it's possible to have a lot of devices including
bridges on a single chip, so that limitations mentioned in the PCI spec
do not work anymore. But I hope hardware engineers are sensible enough
not to break rules...

Appended, but hopefully not quite silly. :-)
Though, the reason why the devices in the dock are still inaccessible
is indeed ridiculous - pci_enable_bridges() doesn't work on i386.
It ends up calling pcibios_enable_resources(), which only test first 6
resources and therefore ignores bridge resources completely.
So, even if the bridge ranges have been assigned correctly (according to
Andreas' dmesg), we left the bridge with IO and MEM enable bits
turned off...

The patch applies to clean 2.6.12-rc6. It includes 2 patches from
gregkh-2.6 tree (to pci.h and probe.c). Initially these patches were
intended for ACPI and "cardbus behind subtractive bridge" improvements,
but as it turns out they make setup-bus.c code a lot more happier with
transparent bridges, so many of previous hacks aren't needed.

I'm still not sure if it boots though...

Ivan.

It does :-))

And the devices on the dock appear to be working, too! I could only test the
USB ports (my wife has currently taken posession of our FireWire MP3 player),
but according to the attached log, the mappings look sensible.
If you'd like me to perform other tests, let me know.

As an aside, hotplugging the dock doesn't work, even though I have compiled in
pciehp and shpchp: /sys/bus/pci/slots/ stays empty. The same with the ACPI
hotplug driver. I do get some messages during boot.

...
Evaluate _OSC Set fails. Status = 0x0005


pciehp: add_host_bridge: status 5
pciehp: Fails to gain control of native hot-plug

...

When I attach the device, nothing happens in dmesg.

In my daily usage, that's fine (I didn't plan on hotplugging the dock anyway).
But if you want me to run more tests and try other patches on that aspect,
I'm game.

Many thanks for the quick help to all of you!

Andreas

I have been following this thread with some interest for the last couple
of days. I am experiencing a similar(but not identical) issue with my
ASUS K8N-DL mobo.

I seem to have no ability to access the onboard ethernet, sound or USB
controller on the machine, and I see some interesting output that looks
an awful lot like the issue Mr. Koch has been investigating. Here is
the output of "dmesg"(Search down for :DMESG) and "lspci -vvt"(Search
down for :LSPCI) for your review.

I have used the latest patch that Mr. Kokshaysky provided against
2.6.12-rc6 with todays "git4" patch. The system always boots, but seems
to be unable to access some of the devices that are on-board.

The on-board Broadcom adapter shows some additional information
in /var/log/messsages when I attempt to DHCP an IP address. I have
placed that log snippet at the end of this message(Search down
for :BROAD).

In order to get on the network to glean some data off of it, I placed a
PCI ethernet card in (Intel 10/100).

Actually, that's not possible, because no difference is permitted.

When the initiator drives an address, there are 4 cycles during which
a targer can assert DEVSEL# to indicate that it will claim the bus
cycle. The first three are known as "fast", "medium", and "slow", and
are for normal devices.

The fourth cycle us reserved for subtractive decode. A subtractive decode
devices must assert DEVSEL# on this cycle and no other. (If and only if
no other device has claimed it by asserting DEVSEL# already.)

On the fifth cycle, the initiator is permitted to perform a master abort
and fail the operation. Because the initator could be any random bus master
card, cards are going to be installed in a system, you can't rely on it
giving a bridge any longer to assert DEVSEL#.

Not possible on only on _real_ PCI bus.

Example: virtually every laptop has mobile bridge and ISA/LPC/whatever
bridge on the same bus segment. Both are subtractive decode devices -
impossible situation from classic PCI point of view. But it's just
happens because it's _not_ PCI but some proprietary bus, even if it looks
like PCI from software point of view. And sort of priority decode is
certainly takes place there.

I'm actually having similar issues to Sean. I have a system with 3 GPUs
(don't ask..) and only one of them seems to be configured correctly. The
others seem to have very strange bar settings...

Just for the record Peter, what motherboard r u using?

On my ASUS K8N-DL, the USB Controller, Sound and Broadcom Ethernet
adapter seem to be inaccessible or unavailable for some reason.

This is a custom motherboard that we've developed in house :-(

It is based on the nforce4 chipset.

Looking at what I see in our lspci output we get strange values for the
bars of the ATI device and the second Nvidia GPU, ie large negative
values. The addresses for these devices also look strange and overlap.

I tried applying the patches from this thread. They change the behaviour
for the configuration of the BARs, but not actually the PCI addresses
for these devices...

I have a bunch more information on this if anyone is willing to take a look.

Actually this might be good news -- you have a chance at fixing your
BIOS to set up the PCI buses sanely, which will probably help Linux out.

basically this works under windows (not a good answer i know...)

my impression from talking to the bios guys it is okay for them not to
configure the non-primary video adapter (read they won't do it).

we do something similar for IB. the IB attached to the master nforce4 is
configured by the bios and the other 3 are not. Each of these IB devices
are configured by Linux correctly.

Similarly when the ATI is the primary graphics adapter it is sanely
configured and the other GPUs are not.

What's wrong with these addresses? They are all unique, AFAIKS.

Sorry, I guess i didn't send that info on. When I have the resources printed out
from dmesg i get:

I can send on the full dmesg if you think it'd be useful.

Ivan:

I tried the patch that seems to work for Andreas. It does not appear to
change the behavior of my machine in the slightest.


And on my ASUS board(2.6.12-rc6 w/git8 and ur patch), I get the
following:

PCI: Cannot allocate resource region 0 of device 0000:02:00.0

PCI: Cannot allocate resource region 3 of device 0000:04:00.0
PCI: Failed to allocate mem resource #3:1000000@fe000000 for


PCI: Bridge: 0000:00:0e.0

Where 02:00.0 is the USB controller, 04:00.0 is the sound card and
00:0e.0 is the bridge for the Broadcom ethernet adapter.

I posted the entire lspci, dmesg and a barf from the tg3 module in the
following post:
http://lkml.org/lkml/2005/6/10/211

I have contacted ASUS for more assistance, but like their web site, it
is intermittent at best.

What can be done at this point?

For entertainment(and learning), I booted my machine with some kernel
command line arguments(pci=routeirq, apic=debug, acpi=verbose). It
yielded information that I am sure most of you folks understand, but it
is all new to me. I have attached the output of dmesg for your review.
