Where does this limit of 4 AFUs come from?
Is this related to CXL_MAX_SLICES?
Should this be a computed value, in case the number of AFUs/slices
is increased at a future date?
The architecture document (CAIA) limits the number of AFUs to 4, though
I don't think anybody as tried with more than 1 so far.
So yes, we could have reused CXL_MAX_SLICES. Since we were just moving
the definition from another file and this is not likely to vary until a
major revision of the architecture, I don't intend to address it in this
patchset, but I've added it to my list of ideas for future cleanup (you
had already mentioned something about hard-coded constants in the
previous series).
memset(0) after kzalloc() is redundant.
yep! Will fix.
