Subject: [PATCH v8 1/2] Drivers: hv: Export some symbols for mshv_vtl
Date: Mon, 13 Oct 2025 06:03:52 +0000 [thread overview]
Message-ID: <20251013060353.67326-2-namjain@linux.microsoft.com> (raw)
In-Reply-To: <20251013060353.67326-1-namjain@linux.microsoft.com>
MSHV_VTL driver is going to be introduced, which is supposed to
provide interface for Virtual Machine Monitors (VMMs) to control
Virtual Trust Level (VTL). Export the symbols needed
to make it work (vmbus_isr, hv_context and hv_post_message).
