Subject: [PATCH 0/2] arm: add kvm-psci-version vcpu property
Date: Thu, 11 Sep 2025 16:49:21 +0200	[thread overview]
Message-ID: <20250911144923.24259-1-sebott@redhat.com> (raw)

This series adds a vcpu knob to request a specific PSCI version
from KVM via the KVM_REG_ARM_PSCI_VERSION FW register.

Note: in order to support PSCI v0.1 we need to drop vcpu
initialization with KVM_CAP_ARM_PSCI_0_2 in that case.
Alternatively we could limit support to versions >=0.2 .
