[Why]
When x or y is negative we set the x and y values to 0 and compensate
with a positive cursor hotspot in DM since DC expects positive cursor
values.
When x or y is less than or equal to the maximum cursor width or height
the cursor hotspot is clamped so the hotspot doesn't exceed the
cursor size:
if (x < 0) {
xorigin = min(-x, amdgpu_crtc->max_cursor_width - 1);
x = 0;
}
if (y < 0) {
yorigin = min(-y, amdgpu_crtc->max_cursor_height - 1);
y = 0;
}
This incorrectly forces the cursor to be at least 1 pixel on the screen
in either direction when x or y is sufficiently negative.
[How]
Just disable the cursor when it goes far enough off the screen in one
of these directions.
This fixes kms_cursor_crc@cursor-256x256-offscreen.

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.
