Subject: [PATCH v5 08/43] hw/cxl/device: Add cheap EVENTS implementation (8.2.9.1)
Date: Wed, 2 Feb 2022 14:10:02 +0000	[thread overview]
Message-ID: <20220202141037.17352-9-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20220202141037.17352-1-Jonathan.Cameron@huawei.com>

From: Ben Widawsky <ben.widawsky@intel.com>

Using the previously implemented stubbed helpers, it is now possible to
easily add the missing, required commands to the implementation.
