[PATCH v4 0/3] KVM/ARM: Fix >256 vcpus

2019-10-03 Thread Eric Auger
Since 4.18, KVM/ARM exposes a KVM_MAX_VCPUS equal to 512. However it was reported [1] that a VM with more than 256 vcpus cannot be launched. 5.4 fixes the situation with 2 patches: - one upgrade of the KVM_IRQ_LINE API [2] supporting a vcpu id encoded on 12 bits, - the reduction of KVM IO devices
