When connectivity with a controller is lost, the driver will keep trying to reconnect once every 10 sec. When connection is restored, user-space apps need to be informed so that they can take proper action. For example, TP8010 introduces the DIM PDU, which is used to register with a discovery controller (DC). The DIM PDU is sent from user-space. The DIM PDU must be sent every time a connection is established with a DC. Therefore, the kernel must tell user-space apps when connection is restored so that registration can happen. The uevent sent is a "change" uevent with environmental data set to: "NVME_EVENT=connected".

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
