[Why] 1) The current calculations for OTO prefetch bandwidth do not consider the number of DPP pipes in use. As a result, OTO prefetch bandwidth may be larger than the vactive bandwidth if multiple DPP pipes are used. OTO prefetch bandwidth should never exceed the vactive bandwidth. 2) Mode programming may be mismatched with mode support In cases where mode support has chosen to use the equalized (equ) prefetch schedule, mode programming may end up using oto prefetch schedule instead. The bandwidth required to do the oto schedule may end up being higher than the equ schedule. This can cause the required urgent bandwidth to exceed the available urgent bandwidth. [How] Output the oto prefetch bandwidth and incorperate it into the urgent bandwidth calculations even if the prefetch schedule being used is not the oto schedule.

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.
