Andrew Lunn says: ==================== mv88e6xxx: Add per port devlink regions This patchset extends devlink regions to support per port regions, and them makes use of them to support the ports of the mv88e6xxx switches. root@rap:~# devlink region show mdio_bus/gpio-0:00/global1: size 64 snapshot [] mdio_bus/gpio-0:00/global2: size 64 snapshot [] mdio_bus/gpio-0:00/atu: size 49152 snapshot [] mdio_bus/gpio-0:00/0/port: size 64 snapshot [] mdio_bus/gpio-0:00/1/port: size 64 snapshot [] mdio_bus/gpio-0:00/2/port: size 64 snapshot [] mdio_bus/gpio-0:00/3/port: size 64 snapshot [] mdio_bus/gpio-0:00/4/port: size 64 snapshot [] mdio_bus/gpio-0:00/5/port: size 64 snapshot [] mdio_bus/gpio-0:00/6/port: size 64 snapshot [] mdio_bus/gpio-0:00/7/port: size 64 snapshot [] mdio_bus/gpio-0:00/8/port: size 64 snapshot [] mdio_bus/gpio-0:00/9/port: size 64 snapshot [] mdio_bus/gpio-0:00/10/port: size 64 snapshot [] root@rap:~# devlink region new mdio_bus/gpio-0:00/1/port snapshot 42 root@rap:~# devlink region dump mdio_bus/gpio-0:00/1/port snapshot 42 0000000000000000 4f 1e 3e 20 00 01 01 39 3f 05 00 00 fd 07 00 00 0000000000000010 80 00 01 00 00 00 00 00 00 00 00 00 00 00 00 91 0000000000000020 00 00 00 00 00 00 00 00 00 00 00 00 22 00 00 00 0000000000000030 07 3e 00 00 00 00 00 80 00 00 00 00 00 00 5b 00 In order to support all ports of the switch, a new devlink flavour has been added for unused ports: mdio_bus/gpio-0:00/0: type notset flavour unused splittable false mdio_bus/gpio-0:00/1: type notset flavour cpu port 1 splittable false mdio_bus/gpio-0:00/2: type eth netdev red flavour physical port 2 splittable fae mdio_bus/gpio-0:00/3: type eth netdev blue flavour physical port 3 splittable fe mdio_bus/gpio-0:00/4: type eth netdev green flavour physical port 4 splittable e mdio_bus/gpio-0:00/5: type notset flavour unused splittable false mdio_bus/gpio-0:00/6: type notset flavour unused splittable false mdio_bus/gpio-0:00/7: type notset flavour unused splittable false mdio_bus/gpio-0:00/8: type eth netdev waic0 flavour physical port 8 splittable e mdio_bus/gpio-0:00/9: type notset flavour unused splittable false mdio_bus/gpio-0:00/10: type notset flavour unused splittable false The DSA core now creates the devlink port instances earlier, so that the driver setup function can make use of them. v3: Whitespace cleanup Added justification for devlink unused flavour Added Tested-by, Reviewed-by: ==================== Signed-off-by: David S.

README
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.
