Currently, KVM ARM/ARM64 only provides in-kernel emulation of Power State and Coordination Interface (PSCI) v0.1.
This patchset aims at providing newer PSCI v0.2 for KVM ARM/ARM64 VCPUs such that it does not break current KVM ARM/ARM64 ABI. Also, the patchset provides emulation of only few PSCI v0.2 functions such as PSCI_VERSION, CPU_ON, and CPU_OFF. Emulation of other PSCI v0.2 functions will be added later.
This doesn't seem to be true any longer does it?
Copy-Paste Error !!!!
I will correct this.
The user space tools (i.e. QEMU or KVMTOOL) will have to explicitly enable KVM_ARM_VCPU_PSCI_0_2 feature using KVM_ARM_VCPU_INIT ioctl for providing PSCI v0.2 to VCPUs.
Besides the stuff you already added, I think you need to also add returning ALREADY_ON for the CPU_ON call if the VCPU requested is already on.
OK, I will add it. Thanks for pointing.
