Register with Subsystem Device/Vendor ID is at offset 0x2c. Export it via the emulated bridge to enable support for the Subsystem Device/Vendor ID - by reading it in the PCI controller config space and storing it in the emulated bridge control structures, so that it is exposed in the respective PCI capability. After this change Subsystem ID is visible in lspci output at line: Capabilities: [40] Subsystem Link: https://lore.kernel.org/r/20220711225915.13896-1-pali@kernel.org Signed-off-by: Pali Rohár <pali@kernel.org> Signed-off-by: Lorenzo Pieralisi <lpieralisi@kernel.org>
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.
