From f432fdfa1215bc3a00468b2e711176be279b0fd2 Mon Sep 17 00:00:00 2001 From: Minwoo Im Date: Sun, 28 Feb 2021 17:51:02 +0900 Subject: hw/block/nvme: support changed namespace asynchronous event If namespace inventory is changed due to some reasons (e.g., namespace attachment/detachment), controller can send out event notifier to the host to manage namespaces. This patch sends out the AEN to the host after either attach or detach namespaces from controllers. To support clear of the event from the controller, this patch also implemented Get Log Page command for Changed Namespace List log type. To return namespace id list through the command, when namespace inventory is updated, id is added to the per-controller list (changed_ns_list). To indicate the support of this async event, this patch set OAES(Optional Asynchronous Events Supported) in Identify Controller data structure.
