Linux kernel source tree
fbd3039a64
As per virtio spec the fields cols and rows are specified as little
endian. Although there is no legacy interface requirement that would
state that cols and rows need to be handled as native endian when legacy
interface is used, unlike for the fields of the adjacent struct
virtio_console_control, I decided to err on the side of caution based
on some non-conclusive virtio spec repo archaeology and opt for using
virtio16_to_cpu() much like for virtio_console_control.event. Strictly
by the letter of the spec virtio_le_to_cpu() would have been sufficient.
But when the legacy interface is not used, it boils down to the same.
And when using the legacy interface, the device formatting these as
little endian when the guest is big endian would surprise me more than
it using guest native byte order (which would make it compatible with
the current implementation). Nevertheless somebody trying to implement
the spec following it to the letter could end up forcing little endian
byte order when the legacy interface is in use. So IMHO this ultimately
needs a judgement call by the maintainers.

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 reStructuredText 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.
