Subject: [PATCH 4/4] target/i386: move accel_cpu_instance_init to .instance_init
Date: Fri, 11 Jul 2025 02:06:03 +0200 [thread overview]
Message-ID: <20250711000603.438312-5-pbonzini@redhat.com> (raw)
In-Reply-To: <20250711000603.438312-1-pbonzini@redhat.com>
With the reordering of instance_post_init callbacks that is new in 10.1
accel_cpu_instance_init must execute in .instance_init as is already
the case for RISC-V. Otherwise, for example, setting the vendor
property is broken when using KVM or Hypervisor.framework, because
KVM sets it *after* the user's value is set by DeviceState's
intance_post_init callback.
