[PATCH v14 07/10] arm64/kvm: Add hypercall service for kvm ptp.

2020-09-04 Thread Jianyong Wu
ptp_kvm will get this service through smccc call. The service offers wall time and counter cycle of host for guest. caller must explicitly determines which cycle of virtual counter or physical counter to return if it needs counter cycle. Signed-off-by: Jianyong Wu --- arch/arm64/kvm/Kconfig
