[openib-general] IB/mthca: question about HCA profile module parameters

[Dotan Barak]

Hi Moni.

I tried to use the mthca module parameter: for example i tried to change 
the number of QPs.

I got several failures when i used the HCA 25204:
* sometimes i got the following error message (when using big values, 
for example 512K QPs):
ib_mthca: 0000:0c: INIT_HCA command failed aborting.
ib_mthca: probe of 0000:0c: failed with error -16
* when i tried to use small amount of QPs (1024) the machine just hanged 
and i noticed a kernel oops message on the console


Did you verify the HCA profile module parameter feature?
Is there is any known limitation for the values that should be used? 
(for example: only values which are power of two)


thanks
Dotan
