When switching to new GPU index after hibernation and then resume, VRAM offset of each VRAM BO will be changed, and the cached gpu addresses needed to updated. This is to enable pdb0 and switch to use pdb0-based virtual gpu address by default in amdgpu_bo_create_reserved(). since the virtual addresses do not change, this can avoid the need to update all cached gpu addresses all over the codebase.

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 reStructuredText 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.
