Debug VRAM access through SDMA has several broken parts resulting in silent MMIO fallback. BO kernel creation takes the location of the cpu addr pointer, not the pointer itself for address kmap. drm_dev_enter return true on success so change access check. The source BO is reserved but not pinned so find the address using the cursor offset relative to its memory domain start.

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.
