Writing the 0x1704 (BUS_BAR1_BLOCK) register causes the GPU to probe the memory region at the programmed address. The result is an address decode error in the external memory controller because address 0, which is what is written to the register, is not designated as accessible to devices. Avoid triggering DMA from the GPU by removing teardown of the BAR1. Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com> |

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.
