[openib-general] getting LOC_QP_OP_ERR with IPoIB - mstflint question

[Moshe Kazir]

I have tested the mstflint problem with two different ppc64 machines :

- On sles 10 PPC64 PowerMac G5  ->  mstflint -d 0001:07:00.0 q    works
o.k. with and without the ib_mthca loaded

- On s;es10 PPC64 IBM JS21   ->  mstflint -d 0001:07:00.0 q    DOESN'T
work with and without the ib_mthca loaded and I have to use
/proc/bus/pci/.....

Is it time to create a  work arround that opens /proc/bus/pci/ .... And
always work ?

Moshe

correct.

Yes, recent kernels disable device access once driver is unloaded:

mstflint -d 08:00.0 q
*** ERROR *** Read a corrupted device id (0xffff). Probably HW/PCI
access problem
*** ERROR *** Device type 65535 not supported.
*** ERROR *** Can not get flash type using device 08:00.0

mstflint should work without driver using /proc:
mstflint -d /proc/bus/pci/08/00.0 q
Image type:      Failsafe
I.S. Version:    1
Chip Revision:   A0


In gen1 flint had a separate driver which you had to load.
I am not sure whether this would work on 2.6.18

Probably not.
