Subject: [PATCH v7 4/5] Drivers: hv: Enable vmbus driver for nested root partition
Date: Thu, 1 Dec 2022 11:03:38 +0000 [thread overview]
Message-ID: <85c3aa671e52fe0f58bcd30c37bd4f60b8bcd14a.1669788587.git.jinankjain@linux.microsoft.com> (raw)
In-Reply-To: <cover.1669788587.git.jinankjain@linux.microsoft.com>
Currently VMBus driver is not initialized for root partition but we need
to enable the VMBus driver for nested root partition. This is required,
so that L2 root can use the VMBus devices.
