Hi,
I'm using RHEL4 kernel (2.6.9), and am trying to make PCI Express
Native Hot-plug driver (pciehp) work on my system (My system has two
hot-pluggable PCI Express slots). I am facing following problem, and
would really appreciate if any one can provide any info regarding this
problem.
When I disable the ACPI support in my kernel configuration, the
("non-acpi") pciehp driver inserts successfully and I see the
following two entries appearing in my /sys/bus/pci/slots:
drwxr-xr-x 2 root root 0 Sep 2 14:28 10
drwxr-xr-x 2 root root 0 Sep 2 14:28 11
However, when I enable the ACPI support in the kernel, the controller
initialization fails giving me following error (excerpts):
......
......
pciehp: pfar:cannot locate acpi bridge of PCI 0xb.
pciehp: pciehprm_find_available_resources = 0xffffffff
pciehp: unable to locate PCI configuration resources for hot plug add.
......
......
pciehp: pfar:cannot locate acpi bridge of PCI 0xe.
pciehp: pciehprm_find_available_resources = 0xffffffff
pciehp: unable to locate PCI configuration resources for hot plug add.
......
......
I am attaching both the logs (The one with ACPI enabled and giving
this error, the other - ACPI disabled and displaying the slot
entries). I am not sure where the problem lies. But the fact that the
entries are appearing correctly when I disable ACPI, combined with
above error messages, I suspect that there is a problem with ACPI
namespace (probably the resources cannot be found using ACPI).
I have two questions:
1) How can I go about tackling this problem? The possibility of BIOS /
Hardware being faulty cannot be ruled out. But then what exactly is
missing and how can that be solved?
2) If the resources are actually missing, then how does the driver
find the required resources when I disable the ACPI from kernel?
Even if no body had faced this problem before, I would really
appreciate if any one can provide ANY kind of pointers / information
regarding this (As I am willing to explore and solve this, no matter
what :-))
TIA

Sorry I forgot to attach the message logs.

Can you try 2.6.13? It is much improved in the pciehp area than 2.6.9.

Hello,
Would you be willing to test the mainline kernel (2.6.13) to see if you
have the same problem with the most recent version of the driver? And
attach the logs again please.
Thanks,

Thanks, for the inputs. I will test it with 2.6.13 and get back.

Hi,
I'm using stock kernel 2.6.13 on RHEL4 Distribution, and am trying to
make PCI Express Native Hot-plug driver (pciehp) work on my system (My
system has two hot-pluggable PCI Express slots). I am facing following
problem, and would really appreciate if any one can provide any info
regarding this problem. (I had earlier tried RHEL4 kernel, but as
suggested by list, have tried with 2.6.13. but to no avail).
When I disable the ACPI support in my kernel configuration, the
("non-acpi") pciehp driver inserts successfully and I see the
following two entries appearing in my /sys/bus/pci/slots:
drwxr-xr-x 2 root root 0 Sep 2 14:28 10
drwxr-xr-x 2 root root 0 Sep 2 14:28 11
However, when I enable the ACPI support in the kernel, the controller
initialization fails giving me following error (excerpts):
......
......
pciehp: pfar:cannot locate acpi bridge of PCI 0xb.
pciehp: pciehprm_find_available_resources = 0xffffffff
pciehp: unable to locate PCI configuration resources for hot plug add.
......
......
pciehp: pfar:cannot locate acpi bridge of PCI 0xe.
pciehp: pciehprm_find_available_resources = 0xffffffff
pciehp: unable to locate PCI configuration resources for hot plug add.
......
......
I am not sure where the problem lies. But the fact that the entries
are appearing correctly when I disable ACPI, combined with above error
messages, I suspect that there is a problem with ACPI namespace
(probably the resources cannot be found using ACPI).
I have two questions:
1) How can I go about tackling this problem? The possibility of BIOS /
Hardware being faulty cannot be ruled out. But then what exactly is
missing and how can that be solved (I can tell my BIOS provider /
hardware provider to correct the problem, but I need to pinpoint the
problem). Is some thing missing in the AML?
2) If the resources are actually missing, then how does the driver
find the required resources when I disable the ACPI from kernel?
I am attaching complete logs of both the cases (The one with ACPI
enabled and giving this error, the other - ACPI disabled and
displaying the slot entries) with highlighted error message. I would
really appreciate if any one can provide me any kind of pointers.
TIA,
Rajat

This is saying that the driver's probe function was called for
these pciehp capable bridges, but it didn't find them in the
ACPI namespace.

At init time, the pciehp driver scans the ACPI namespace and tries
to collect resources for all bridges - host as well as PCI. It's
pretty rare for BIOS to describe PCI bridge resources in ACPI
namespace, so that's not unusual. What's unexpected is that these
pciehp bridges weren't even listed in the namespace.
With the pciehp version that has acpi disabled, it's not going to
try to get bridge resources and other information from acpi. In
that case, it simply reads the bridge config space to determine
resource ranges it is decoding. This is what the acpi version of
pciehp also defaults to for PCI bridges that are listed without
resource descriptions in the acpi namespace. So, the error you
are running into is somewhat bogus. The proper long term fix
is to change pciehp to not depend so much on acpi and just use
the pci core for resource management. In the meantime, you should
just use the non-acpi version of pciehp.

Hi Rajesh,
Thanks for the insight. But my doubt is that the PCI Express devices
down the hot-pluggable slots are working fine. i.e. if we forget about
the hot-plugging / unplugging, the bridges and devices are working
fine, even with ACPI enabled.
So is the presence of bridges in ACPI namespace required only for
hot-plugging / unplugging and not for normal operation?
Thanks,
Rajat

Yes, that's correct. The PCI core will correctly scan PCI bridges
independent of their presence in the acpi namespace.
PS: trimming the cc list a bit, as I'm getting rejects due to
too many recipients. pcihp-discuss is the correct list for pciehp
related questions.

Hi Rajesh,
Thanks a lot, for ending my doubts. I am working on a hardware that is
still under development. So the chances of missing certain things in
hardware / BIOS are high. So the solution for this is to ask my
Hardware vendor to provide the information for these bridges into the
ACPI namespace (AML / DSDT?)?
Thanks a ton,
Rajat
