Depending on platform configuration, certain VMD devices may have an
additional configuration option which specifies the range of bus numbers
allowed in a VMD PCIe domain. We determine this requirement by checking
the value of two vendor specific config registers in the VMD endpoint:
VMCAP[0] | VMCONFIG[9:8] | Bus Numbers
----------------------------------------
0 | * | 0-255
1 | 00 | 0-127
1 | 01 | 128-255
1 | 10 | 0-255
This feature is also added as a bit in driver_data, to allow future
conforming device ids which support these features to be enabled through
sysfs new_id.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
