From 955a3fc6d2a1c11d6d00bce4f3816100ce0530cf Mon Sep 17 00:00:00 2001 From: Linu Cherian Date: Wed, 8 Mar 2017 11:38:35 +0530 Subject: [PATCH] KVM: arm64: Increase number of user memslots to 512 Having only 32 memslots is a real constraint for the maximum number of PCI devices that can be assigned to a single guest. Assuming each PCI device/virtual function having two memory BAR regions, we could assign only 15 devices/virtual functions to a guest. Hence increase KVM_USER_MEM_SLOTS to 512 as done in other archs like powerpc.
