Pete -
We stumbled across some hardware issues/limitations with our IB
hardware, and have 'devised' a way of working around these
limitations by increasing the sizes of memory region allocations
inside BMI, currently we're seeing chunks or blocks of 64KB being
allocated on the hardware level (this is what the firmware people
show us is allocated physically)
Is there a way we can tune these allocation calls to the IB drivers,
it should increase our ability to make large pinning requests if we
can use larger than 64KB, they suggest 2MB.
Are you aware of any specific memory region sizes that are allocated
in the BMI-IB layers?
