Several bugs as outlined in udev-hid-bpf#66 and udev-hid-bpf!198: - pressure curve is far from linear - tilt range is ±60, not ±127 - pressing the second button sets both tip down and barrel switch Fix the second button by adding a Secondary Barrel Switch in the existing padding and check for the tip down/barrel switch down combo. When both values become true at the same time, set the Secondary Barrel Switch instead. Implement a custom pressure curve that maps the hardware range 0-102 linearly to the logical range 0-1224, and maps the hardware range 103-2047 logarithmically to the logical range 1232-2047. This mapping isn’t perfect, but it’s way more natural than the stock configuration.

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.
