Subject: [PATCH 4/4] hw/intc/aplic: refine kvm_msicfgaddr
Date: Mon, 17 Feb 2025 16:19:26 +0800	[thread overview]
Message-ID: <20250217081927.10613-5-yongxuan.wang@sifive.com> (raw)
In-Reply-To: <20250217081927.10613-1-yongxuan.wang@sifive.com>

Let kvm_msicfgaddr use the same format with mmsicfgaddr and smsicfgaddr.
