Subject: [PATCH v2 0/4] KVM: arm64: Don't perform vgic-v2 lazy init on timer injection
Date: Wed, 22 Apr 2026 11:02:06 +0100	[thread overview]
Message-ID: <20260422100210.3008156-1-maz@kernel.org> (raw)

This is the second version of this series aiming at fixing issues
with vgic-v2 being initialised from non-preemptible context.

* From v1 [1]:

  - Repaint kvm_timer_irq_can_fire() to kvm_timer_enabled()

  - Drop duplicate kvm_timer_update_status() call

  - Force lazy init on the irqfd slow-path for SPIs

  KVM: arm64: timer: Repaint kvm_timer_{should,irq_can}_fire() to
    kvm_timer_{pending,enabled}()
  KVM: arm64: timer: Kill the per-timer level cache
  KVM: arm64: vgic-v2: Force vgic init on injection outside the run loop
  KVM: arm64: vgic-v2: Don't init the vgic on in-kernel interrupt
    injection
