KVM: arm64: arch_timer: Remove VGIC initialization check

2020-12-23T16:43:12Z

kvm_timer_enable() is called in kvm_vcpu_first_run_init() after kvm_vgic_map_resources() if the VGIC wasn't ready. kvm_vgic_map_resources() is the only place where kvm->arch.vgic.ready is set to true. For a v2 VGIC, kvm_vgic_map_resources() will attempt to initialize the VGIC and set the initialized flag. For a v3 VGIC, kvm_vgic_map_resources() will return an error code if the VGIC isn't already initialized. The end result is that if we've reached kvm_timer_enable(), the VGIC is initialzed and ready and vgic_initialized() will always be true, so remove this check.

KVM: arm64: timers: Move timer registers to the sys_regs file

2020-07-07T08:28:38Z

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. Signed-off-by: Marc Zyngier

KVM: arm64: timers: Rename kvm_timer_sync_hwstate to kvm_timer_sync_user

2020-07-07T08:28:38Z

kvm_timer_sync_hwstate() has nothing to do with the timer HW state, but more to do with the state of a userspace interrupt controller. Change the suffix from _hwstate to_user, in keeping with the rest of the code. Signed-off-by: Marc Zyngier

Merge tag 'kvmarm-5.8' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD

2020-06-01T08:26:27Z

KVM/arm64 updates for Linux 5.8: - Move the arch-specific code into arch/arm64/kvm - Start the post-32bit cleanup - Cherry-pick a few non-invasive pre-NV patches

KVM: arm64: Simplify __kvm_timer_set_cntvoff implementation

2020-05-16T14:04:18Z

Now that this function isn't constrained by the 32bit PCS, let's simplify it by taking a single 64bit offset instead of two 32bit parameters. Signed-off-by: Marc Zyngier

KVM: arm64: Move virt/kvm/arm to arch/arm64

2020-05-16T14:03:59Z

Now that the 32bit KVM/arm host is a distant memory, let's move the whole of the KVM/arm64 code into the arm64 tree. As they said in the song: Welcome Home (Sanitarium). Signed-off-by: Marc Zyngier Acked-by: Will Deacon Link: https://lore.kernel.org/r/20200513104034.74741-1-maz@kernel.org
