Some TI KeyStone C667X devices do not support bus/hot reset. The PCIESS automatically disables LTSSM when Secondary Bus Reset is received and device stops working. Prevent bus reset for these devices. With this change, the device can be assigned to VMs with VFIO, but it will leak state between VMs. Reference: https://e2e.ti.com/support/processors/f/791/t/954382 Link: https://lore.kernel.org/r/20210315102606.17153-1-antti.jarvinen@gmail.com Signed-off-by: Antti Järvinen <antti.jarvinen@gmail.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Kishon Vijay Abraham I <kishon@ti.com> Cc: stable@vger.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.
