Subject: [RFC v11 46/55] target/arm: cpu-sve: split TCG and KVM functionality
Date: Tue, 23 Mar 2021 16:46:30 +0100 [thread overview]
Message-ID: <20210323154639.23477-39-cfontana@suse.de> (raw)
In-Reply-To: <20210323151749.21299-1-cfontana@suse.de>
put the KVM-specific and TCG-specific functionality
in the respective subdirectories kvm/ and tcg/
