Subject: [RFC PATCH V4 17/17] x86/sev: Remove restrict interrupt injection from SNP_FEATURES_IMPL_REQ
Date: Mon, 3 Apr 2023 13:44:05 -0400 [thread overview]
Message-ID: <20230403174406.4180472-18-ltykernel@gmail.com> (raw)
In-Reply-To: <20230403174406.4180472-1-ltykernel@gmail.com>
From: Tianyu Lan <tiala@microsoft.com>
Enabled restrict interrupt injection function. Remove MSR_AMD64_
SNP_RESTRICTED_INJ from SNP_FEATURES_IMPL_REQ to let kernel boot
up with this function.
