This is a comtinuation of "KVM: x86: Drop arbitraty KVM_SOFT_MAX_VCPUS" (https://lore.kernel.org/kvm/[email protected]/) 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) Vitaly Kuznetsov (5): KVM: arm64: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS KVM: MIPS: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS KVM: PPC: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS KVM: RISC-V: Cap KVM_CAP_NR_VCPUS by KVM_CAP_MAX_VCPUS KVM: x86: Drop arbitraty KVM_SOFT_MAX_VCPUS arch/arm64/kvm/arm.c | 7 ++++++- arch/mips/kvm/mips.c | 2 +- arch/powerpc/kvm/powerpc.c | 4 ++-- arch/riscv/kvm/vm.c | 2 +- arch/x86/include/asm/kvm_host.h | 1 - arch/x86/kvm/x86.c | 2 +- 6 files changed, 11 insertions(+), 7 deletions(-) -- 2.33.1
