Subject: [PATCH 3/9] target/arm: hvf: instantiate GIC early
Date: Fri, 25 Jul 2025 10:34:25 +0200	[thread overview]
Message-ID: <20250725083431.91450-4-mohamed@unpredictable.fr> (raw)
In-Reply-To: <20250725083431.91450-1-mohamed@unpredictable.fr>

While figuring out a better spot for it, put it in hv_arch_vm_create().
