Linux kernel source tree
f86a1909ea
In several places, a Boolean flag is used in the GSI code to indicate whether the "doorbell engine" should be enabled or not when a channel is configured. This is basically done to abstract this property from the IPA version; the GSI code doesn't otherwise "know" what the IPA hardware version is. The doorbell engine is enabled only for IPA v3.5.1, not for IPA v4.0 and later. The next patch makes another change that affects behavior during channel reset (which also involves programming the channel). It also distinguishes IPA v3.5.1 hardware from newer hardware. Rather than creating another flag whose value matches the "db_enable" value, just rename "db_enable" to be "legacy" so it can be used to signal more than just the special doorbell handling.

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.
