Subject: [PATCH] arm64: KVM: Increase max VCPUs per-Guest to 8
Date: Wed, 11 Sep 2013 18:32:32 +0530 [thread overview]
Message-ID: <1378904552-29347-1-git-send-email-anup.patel@linaro.org> (raw)
Current max VCPUs per-Guest is set to 4 which is preventing
us from creating a Guest (or VM) with 8 VCPUs on Host (e.g.
X-Gene Storm SOC) with 8 Host CPUs.
The correct value of max VCPUs per-Guest should be same as
the max CPUs supported by GICv2 which is 8 hence this patch
increases KVM_MAX_VCPUS to 8.
