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

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.

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.

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 ^ permalink raw reply [flat|nested] 10+ messages in thread

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.

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?)?

It is much improved in the pciehp area than 2.6.9. thanks, greg k-h - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs ^ permalink raw reply [flat|nested] 10+ messages in thread
