Subject: [PATCH v2 05/14] KVM: arm64: Advertise NV2 in the boot messages
Date: Thu, 20 Feb 2025 13:48:58 +0000 [thread overview]
Message-ID: <20250220134907.554085-6-maz@kernel.org> (raw)
In-Reply-To: <20250220134907.554085-1-maz@kernel.org>
Make it a bit easier to understand what people are running by
adding a +NV2 string to the successful KVM initialisation.
