The current code uses diag210 to infer the 3270 geometry from the model number when running on z/VM. This doesn't work well as almost all 3270 software clients report as 3279-2 with a custom resolution. tty3270 assumes it has a 80x24 terminal connected because of the -2 suffix. Use diag 8c to fetch the realy geometry from z/VM. Note that this doesn't allow dynamic resizing, i.e. reconnecting to a z/VM session with a different geometry.

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.
