Subject: [PATCH v2 07/14] target/i386/hvf: provide and use simulate_{wrmsr, rdmsr} in emul_ops
Date: Fri, 7 Mar 2025 11:55:18 -0800 [thread overview]
Message-ID: <1741377325-28175-8-git-send-email-liuwe@linux.microsoft.com> (raw)
In-Reply-To: <1741377325-28175-1-git-send-email-liuwe@linux.microsoft.com>
Change the first argument's type to be CPUState to match other hooks.
