Hello,
Here are cleanups which try to deobfuscate some magic values used in
the driver and add documentation in the commit logs. The only
significant change is on the size of the VP space which now depends on
the number of EQ descriptors. We have 1M of these and we use 8
priorities per VP. Therefore, our VP space should be limited to 128k.
Tested on a boston with 256 KVM guests each with 4 vCPUS. For the
record, it takes 25s for all to reach login.
Thanks,
C.
