Re: [Pcihpd-discuss] Re: ACPI problem with PCI Express Native Hot-plug driver

[Rajat Jain]

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
