Hi Andre,
I don't understand why it's so difficult to eliminate the 64 CPU limit.
Because bitmap operations are not trivial to be done right (look at
Linux' implementation). I will send a patch later (introducing generic
bitmap operations), but I didn't want to merge this with the NUMA patchset.
I'm willing to take these patches with the limit but I'd like to see the
following:
The -numa stuff needs to be more defensive when -smp > 64.
Specificially, it needs to explicitly check and warn the user if a NUMA
node contains a CPU > 64.
OK, done.
Each patch needs some description of what it's doing. All patches need
a SoB.
Agreed. But git should have already added a SoB line for every patch, no?
Regards,
Andre.
