As stated in APCI spec, the size of the subspace shared memory region may
be different for different types. So it is useful for driver to fill PCC
communication space. But the driver used this PCC channel doesn't know what
is the subspace type of the channel.
So export the PCC subspace type by requesting PCC channel.
I would prefer to avoid this, but please post it with user to get better
understanding of it.
Hi Sudeep,
Thanks for your fast review.
Sorry, I cannot fully understand what you mean. What should I do for it?
Currently, it seems that the subspace type in all drivers used PCC is
fixed and not obtained from their platform.
IMO, PCCT is a best natural way to export it.
