Subject: [PATCH v0 2/6] Hyper-V: Add two new hypercall numbers to guest ABI public header
Date: Wed, 3 Sep 2025 19:10:13 -0700 [thread overview]
Message-ID: <20250904021017.1628993-3-mrathor@linux.microsoft.com> (raw)
In-Reply-To: <20250904021017.1628993-1-mrathor@linux.microsoft.com>
In preparation for upcoming crashdump patches, this commit copies two new
hypercall numbers to the guest ABI header published by Hyper-V. One to
notify hypervisor of an event that occurs in the root partition, other
to ask hypervisor to disable the hypervisor.
