[PATCH 0/5] KVM: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS and re-purpose it on x86

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is a comtinuation of "KVM: x86: Drop arbitraty KVM_SOFT_MAX_VCPUS"
(https://lore.kernel.org/kvm/20211111134733.86601-1-vkuznets@xxxxxxxxxx/)
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)
