User applications alert the driver when the Doorbell FIFO reaches the alarm threshold. The driver updates the pacing parameters in the shared page to do the maximum pacing by the application till the DB FIFO congestion reduces to pacing threshold. Driver keeps checking the DB FIFO depth at the pacing interval and gradually adjusts the pacing level. Once the pacing level reaches default values (no congestion in the FIFO) pacing gets completed.

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.
