arm: Remove 32bit KVM host support

2020-03-24T10:56:04+00:00

That's it. Remove all references to KVM itself, and document that although it is no more, the ABI between SVC and HYP still exists.

arm/arm64: KVM: Allow a VCPU to fully reset itself

2019-02-07T11:44:13+00:00

The current kvm_psci_vcpu_on implementation will directly try to manipulate the state of the VCPU to reset it. However, since this is not done on the thread that runs the VCPU, we can end up in a strangely corrupted state when the source and target VCPUs are running at the same time. Fix this by factoring out all reset logic from the PSCI implementation and forwarding the required information along with a request to the target VCPU.

KVM: arm/arm64: Move timer IRQ default init to arch_timer.c

2017-06-08T14:59:56+00:00

We currently initialize the arch timer IRQ numbers from the reset code, presumably because we once intended to model multiple CPU or SoC types from within the kernel and have hard-coded reset values in the reset code. As we are moving towards userspace being in charge of more fine-grained CPU emulation and stitching together the pieces needed to emulate a particular type of CPU, we should no longer have a tight coupling between resetting a VCPU and setting IRQ numbers. Therefore, move the logic to define and use the default IRQ numbers to the timer code and set the IRQ number immediately when creating the VCPU.

KVM: arm/arm64: timer: Allow the timer to control the active state

2015-08-12T10:28:26+00:00

In order to remove the crude hack where we sneak the masked bit into the timer's control register, make use of the phys_irq_map API control the active state of the interrupt. This causes some limited changes to allow for potential error propagation. Reviewed-by: Christoffer Dall Signed-off-by: Marc Zyngier
