[Xen-devel] InfiniBand device in Xen

[Lukas Hejtmanek <xhejtman@xxxxxxxxxxx>]

Hello,

I'm trying to get working infiniband device in Xen. I have Xen v3 with 2.6.18
kernel. I export PCI device from Dom0 into DomU. I've enabled permisive device
in Dom0.

However, inserting infiniband module results in the following messages (with
little more verbosity which I have added):

pcifront pci-0: Installing PCI frontend
pcifront pci-0: Creating PCI Frontend Bus 0000:08
...
ib_mthca: Mellanox InfiniBand HCA driver v0.08 (February 14, 2006)
ib_mthca: Initializing 0000:08:00.0
PCI: Enabling device 0000:08:00.0 (0000 -> 0002)
PCI: Setting latency timer of device 0000:08:00.0 to 64
ib_mthca 0000:08:00.0: Reset OK!
Go bit val: -1
mthca_cmd_post_hcr: returning EAGAIN
mthca_cmd_box: error -11
ib_mthca 0000:08:00.0: QUERY_FW command failed, aborting.
ib_mthca: probe of 0000:08:00.0 failed with error -11

Do you have any advices what should I try? The device running in Dom0 works as
expected. The problem is in DomU with exported PCI device.

It seems that the iomapped adrea returns all ones instead of reasonable values.

(I'm *not* in the list, please cc me)
