Subject: [PATCH v1 3/5] target/arm: make psci call can be used by kvm
Date: Mon, 26 Jun 2023 02:49:07 -0400	[thread overview]
Message-ID: <20230626064910.1787255-4-shahuang@redhat.com> (raw)
In-Reply-To: <20230626064910.1787255-1-shahuang@redhat.com>

Now the psci call can only be used when tcg_enabled, we want to reuse it
when kvm_enabled, which will be used in subsequent patch which enable
the psci handling in userspace.
