From Documentation/admin-guide/kernel-parameters.txt, specifically the
last sentence:
nohz_full= [KNL,BOOT,SMP,ISOL]
The argument is a cpu list, as described above.
In kernels built with CONFIG_NO_HZ_FULL=y, set
the specified list of CPUs whose tick will be stopped
whenever possible. The boot CPU will be forced outside
the range to maintain the timekeeping. Any CPUs
in this list will have their RCU callbacks offloaded,
just as if they had also been called out in the
rcu_nocbs= boot parameter.
The kernel or-s the nohz_full cpumask into the rcu_nocbs cpumask at
startup, and uses that.

There are two warnings in the VFIO section about limitations of VFIO and
limitations on who can bind/unbind devices. Since these don't actually
describe any unsafe conditions, and are more informational, we can
change these to notes. This also helps emphasise the other warnings in
the documents which flag genuine security concerns.

Rather than having separate sections for VFIO and VFIO no-iommu mode, as
well as a separate section further down the document on troubleshooting
VFIO, we can consolidate all these as subsections into a primary VFIO
section. This section starts with the basics of VFIO use, then covers
no-iommu mode, before moving on to the more advanced topics such as
creating VFs and ending with the troubleshooting subsection.

To further de-emphasise UIO over the alternatives, we can move the UIO

The VFIO section of the page about Linux drivers was rather long and
unstructured. This can be improved by splitting it up into subsections,
to cover the specifics of memory limits and creating VFs. When moving
the various text notes into the relevant subsections, we can drop the
note about kernels earlier than 3.6, since DPDK no longer supports
kernels that old.

While the details of VFIO and UIO may be of interest to some, most users
of the doc are likely primarily interested in how to bind their devices
to the kernel driver and then move on to running the app. Therefore, the
most important part of the "Linux Drivers" section of the GSG is the
subsection on "Binding and Unbinding", so put that first.
Signed-off-by: Bruce Richardson <bruce.richardson@intel.com>
The GSG has a note warning that use of UIO is inherently unsafe due to
lack of IOMMU protection. However, this was only flagged as a "NOTE",
meaning it could easily be missed. Changing the rst tag from "note" to
"warning" and moving it to the top of the UIO subsection makes this a
lot more visible to users.

The "Linux Drivers" section of the GSG already notes that, for use of
UIO, the IOMMU must be disabled or put into pass-through mode.
Therefore, there is no need to duplicate this information in the
"additional functionality" section. Also the kernel configuration
options documented in the section are enabled as standard on all common
distro kernels, so the information should not be needed in a GSG doc.

The KNI library is disabled by default in DPDK and is already documented
in the programmers guide and also in the sample application guide. There
are also in-kernel alternatives to it. Therefore, we can drop the

As best we can tell, the HPET timers are not commonly used, so there is
little need to give extensive detail and commentry on them in the Linux

importance.

Not all directories were given in the GSG document, but many of those
omitted would be of interest to users, e.g. "doc", "license" and
"usertools" directories. Adding these leaves only "devtools", and
"kernel" as the only undocumented directories, so add them in too for
completeness.
When updating the section, add "including" to the line leading up to the
directory list, indicating that, while the list is currently complete,
it is not guaranteed to always be.

When building end-applications linked with DPDK, the only additional
tool needed is pkg-config/pkgconf. However, the standard development
tools meta-packages on most distro's include this as standard, meaning
it does not really require its own section. The one outlier in the
existing text is "alpine" where it is not present when using "libc-dev"
target. However, changing "gcc" and "libc-dev" to "alpine-sdk"
metapackage aligns alpine with the other distros in this regard.

A note about secure boot not allowing UIO is present in both the system
requirements section and the driver binding section. This fits better in
the driver binding section, so the copy in system requirements can be
removed. The document in general now also emphasises VFIO over UIO more
than when this note was first added, reducing the need for this warning
to be repeated.
