Subject: [PATCH 0/5] KVM: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS and re-purpose it on x86
Date: Thu, 11 Nov 2021 17:27:41 +0100 [thread overview]
Message-ID: <20211111162746.100598-1-vkuznets@redhat.com> (raw)
This is a comtinuation of "KVM: x86: Drop arbitraty KVM_SOFT_MAX_VCPUS"
(https://lore.kernel.org/kvm/20211111134733.86601-1-vkuznets@redhat.com/)
work.
1) Enforce KVM_CAP_NR_VCPUS <= KVM_CAP_MAX_VCPUS rule on all
architectures. [Sean Christopherson]
2) Make KVM_CAP_NR_VCPUS return num_online_cpus() and not an arbitrary
value of '710' on x86.
Everything but x86 was only 'eyeball tested', the change is trivial
but sorry in advance if I screwed up)
