Subject: [PATCH hyperv-next v5 05/11] arm64: hyperv: Initialize the Virtual Trust Level field
Date: Fri, 7 Mar 2025 14:02:57 -0800 [thread overview]
Message-ID: <20250307220304.247725-6-romank@linux.microsoft.com> (raw)
In-Reply-To: <20250307220304.247725-1-romank@linux.microsoft.com>
Various parts of the hyperv code need to know what VTL
the kernel runs at, most notably VMBus needs that to
establish communication with the host.
Initialize the Virtual Trust Level field to enable
booting in the Virtual Trust Level.
