Subject: [PATCH v4 20/25] nvdimm/ocxl: Add an IOCTL to request controller health & perf data
Date: Fri, 27 Mar 2020 18:11:57 +1100	[thread overview]
Message-ID: <20200327071202.2159885-21-alastair@d-silva.org> (raw)
In-Reply-To: <20200327071202.2159885-1-alastair@d-silva.org>

When health & performance data is requested from the controller,
it responds with an error log containing the requested information.

This patch allows the request to be issued via an IOCTL, the data
can later be collected in userspace via the error log IOCTL introduced
in a previous patch. Userspace will be notified of pending error
logs via an event.
