In case of panels with low vertical back porch, the prefill bw requirement will be high as we will have less time(vbp+pw) to fetch and fill the hw latency buffers before start of first line in active period. For ex: Say hw_latency_line_buffers = 24, and if blanking vbp+pw = 10 Here we need to fetch 24 lines of data in 10 line times. This will increase the bw to the ratio of linebuffers to blanking. DPU hw can also fetch data during vertical front porch provided interface prefetch is enabled. Use vfp in the prefill calculation as dpu driver enables prefetch if the blanking is not sufficient to fill the latency lines.

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.
