Subject: [PATCH 0/1] KVM: PPC: Increase memslots
Date: Wed, 04 Nov 2015 09:03:47 +0000 [thread overview]
Message-ID: <1446627828-3347-1-git-send-email-thuth@redhat.com> (raw)
Now that the patch from Nikunj to support the KVM_CAP_NR_MEMSLOTS
capability on powerpc has been merged to kvm/next, we can/should
increase the amount of memslots on ppc, too.
Since nobody else sent a patch yet (as far as I can see), I'd like
to suggest to increase the slot number to 320 now. Why 320? Well,
x86 uses 509 (+3 internal slots), to give enough space for
256 pluggable DIMMs and 253 other slots (for PCI etc.).
On powerpc, QEMU only supports 32 pluggable DIMMs, so I think we
should be fine by using something around 253 + 32 slots + some few
extra ... so 320 sounds like a good value to me for the time
being (but in the long run, we should really make this dynamically
instead, I think).
