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.

There may be a potential integer overflow issue in _dpu_core_perf_calc_clk(). crtc_clk is defined as u64, while mode->vtotal, mode->hdisplay, and drm_mode_vrefresh(mode) are defined as a smaller data type. The result of the calculation will be limited to "int" in this case without correct casting. In screen with high resolution and high refresh rate, integer overflow may happen. So, we recommend adding an extra cast to prevent potential integer overflow.
