Subject: [PATCH v10 12/18] x86/sev: Enable NMI support for Secure AVIC
Date: Thu, 28 Aug 2025 16:43:15 +0530 [thread overview]
Message-ID: <20250828111315.208959-1-Neeraj.Upadhyay@amd.com> (raw)
In-Reply-To: <20250828070334.208401-1-Neeraj.Upadhyay@amd.com>
From: Kishon Vijay Abraham I <kvijayab@amd.com>
Now that support to send NMI IPI and support to inject NMI from
the hypervisor has been added, set V_NMI_ENABLE in VINTR_CTRL
field of VMSA to enable NMI for Secure AVIC guests.
