Subject: [ndctl PATCH v4 07/17] libcxl: add GET_HEALTH_INFO mailbox command and accessors
Date: Thu, 7 Oct 2021 02:21:29 -0600 [thread overview]
Message-ID: <20211007082139.3088615-8-vishal.l.verma@intel.com> (raw)
In-Reply-To: <20211007082139.3088615-1-vishal.l.verma@intel.com>
Add libcxl APIs to create a new GET_HEALTH_INFO mailbox command, the
command output data structure (privately), and accessor APIs to return
the different fields in the health info output.
