Subject: [PATCH v24 02/18] cpu: call AccelCPUClass::cpu_realizefn in cpu_exec_realizefn
Date: Fri, 26 Feb 2021 10:49:23 +0100
Message-ID: <20210226094939.11087-3-cfontana@suse.de> (raw)
In-Reply-To: <20210226094939.11087-1-cfontana@suse.de>

move the call to accel_cpu->cpu_realizefn to the general
cpu_exec_realizefn from target/i386, so it does not need to be
called for every target explicitly as we enable more targets.
