Description:
This file contains the number of virtual PTP clocks in

the corresponding number of virtual clocks and causes
the physical clock to become free running. Setting the
value back to 0 deletes the virtual clocks and
switches the physical clock back to normal, adjustable
operation.

TODO(brendanhiggins@google.com): There are various issues with UML and

need some investigation.
.. note::
TODO(brendanhiggins@google.com): for recent versions of Linux
(5.10-5.12, maybe earlier), there's a bug with gcov counters not being
flushed in UML. This translates to very low (<1%) reported coverage. This is
related to the above issue and can be worked around by replacing the
one call to ``uml_abort()`` (it's in ``os_dump_core()``) with a plain

IMX8 glue layer controller, NXP imx8 families support Synopsys MAC 5.10a IP.
This file documents platform glue layer for IMX.
Please see stmmac.txt for the other unchanged properties.
The device node has following properties.
Required properties:
- compatible: Should be "nxp,imx8mp-dwmac-eqos" to select glue layer
and "snps,dwmac-5.10a" to select IP version.
- clocks: Must contain a phandle for each entry in clock-names.
- clock-names: Should be "stmmaceth" for the host clock.
Should be "pclk" for the MAC apb clock.
Should be "ptp_ref" for the MAC timer clock.
Should be "tx" for the MAC RGMII TX clock:
Should be "mem" for EQOS MEM clock.
- "mem" clock is required for imx8dxl platform.
- "mem" clock is not required for imx8mp platform.
- interrupt-names: Should contain a list of interrupt names corresponding to
the interrupts in the interrupts property, if available.
Should be "macirq" for the main MAC IRQ
Should be "eth_wake_irq" for the IT which wake up system
- intf_mode: Should be phandle/offset pair. The phandle to the syscon node which
encompases the GPR register, and the offset of the GPR register.
- required for imx8mp platform.
- is optional for imx8dxl platform.
Optional properties:
- intf_mode: is optional for imx8dxl platform.
- snps,rmii_refclk_ext: to select RMII reference clock from external.

- reg-io-width : Specify the size (in bytes) of the IO accesses that
should be performed on the device. Valid value for SMSC LAN is
2 or 4. If it's omitted or invalid, the size would be 2.
- smsc,irq-active-high : Indicates the IRQ polarity is active-high

Linux Kernel TIPC
=================
TIPC (Transparent Inter Process Communication) is a protocol that is
specially designed for intra-cluster communication.
Introduction
============
For more information about TIPC, see http://tipc.sourceforge.net.
TIPC (Transparent Inter Process Communication) is a protocol that is specially
designed for intra-cluster communication. It can be configured to transmit
messages either on UDP or directly across Ethernet. Message delivery is
sequence guaranteed, loss free and flow controlled. Latency times are shorter
than with any other known protocol, while maximal throughput is comparable to
that of TCP.
TIPC Features
-------------
- Cluster wide IPC service
Have you ever wished you had the convenience of Unix Domain Sockets even when
transmitting data between cluster nodes? Where you yourself determine the
addresses you want to bind to and use? Where you don't have to perform DNS
lookups and worry about IP addresses? Where you don't have to start timers
to monitor the continuous existence of peer sockets? And yet without the
downsides of that socket type, such as the risk of lingering inodes?
Welcome to the Transparent Inter Process Communication service, TIPC in short,
which gives you all of this, and a lot more.
- Service Addressing
A fundamental concept in TIPC is that of Service Addressing which makes it
possible for a programmer to chose his own address, bind it to a server
socket and let client programs use only that address for sending messages.
- Service Tracking
A client wanting to wait for the availability of a server, uses the Service
Tracking mechanism to subscribe for binding and unbinding/close events for
sockets with the associated service address.
The service tracking mechanism can also be used for Cluster Topology Tracking,
i.e., subscribing for availability/non-availability of cluster nodes.
Likewise, the service tracking mechanism can be used for Cluster Connectivity
Tracking, i.e., subscribing for up/down events for individual links between
cluster nodes.
- Transmission Modes
Using a service address, a client can send datagram messages to a server socket.
Using the same address type, it can establish a connection towards an accepting
server socket.
It can also use a service address to create and join a Communication Group,
which is the TIPC manifestation of a brokerless message bus.
Multicast with very good performance and scalability is available both in
datagram mode and in communication group mode.
- Inter Node Links
Communication between any two nodes in a cluster is maintained by one or two
Inter Node Links, which both guarantee data traffic integrity and monitor
the peer node's availability.
- Cluster Scalability
By applying the Overlapping Ring Monitoring algorithm on the inter node links
it is possible to scale TIPC clusters up to 1000 nodes with a maintained
neighbor failure discovery time of 1-2 seconds. For smaller clusters this
time can be made much shorter.
- Neighbor Discovery
Neighbor Node Discovery in the cluster is done by Ethernet broadcast or UDP
multicast, when any of those services are available. If not, configured peer
IP addresses can be used.
- Configuration
When running TIPC in single node mode no configuration whatsoever is needed.
When running in cluster mode TIPC must as a minimum be given a node address
(before Linux 4.17) and told which interface to attach to. The "tipc"
configuration tool makes is possible to add and maintain many more
configuration parameters.
- Performance
TIPC message transfer latency times are better than in any other known protocol.
Maximal byte throughput for inter-node connections is still somewhat lower than
for TCP, while they are superior for intra-node and inter-container throughput
on the same host.
- Language Support
The TIPC user API has support for C, Python, Perl, Ruby, D and Go.
