When creating a user-mode SDMA queue, CP FW expects driver to use/set virtual SDMA engine id in MAP_QUEUES packet instead of using the physical SDMA engine id. Each partition node's virtual SDMA number should start from 0. However, when allocating doorbell for the queue, KFD needs to allocate the doorbell from doorbell space corresponding to the physical SDMA engine id, otherwise the hwardware will not see the doorbell press.

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.
