Hi Marc, -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Marc Zyngier Sent: Thursday, August 6, 2020 1:57 AM To: Paolo Bonzini <[email protected]> Cc: Peng Hao <[email protected]>; [email protected]; [email protected]; Will Deacon <[email protected]>; Catalin Marinas <[email protected]>; Alexander Graf <[email protected]>; [email protected]; [email protected] Subject: [PATCH 47/56] KVM: arm64: timers: Move timer registers to the sys_regs file
Move the timer gsisters to the sysreg file. This will further help when they are directly changed by a nesting hypervisor in the VNCR page. This requires moving the initialisation of the timer struct so that some of the helpers (such as arch_timer_ctx_index) can work correctly at an early stage.

As in my ptp_kvm implementation I need get VCNT offset value separately not just give me a result of VCNT.
