Older HW only supports debugging on a single process because the SPI debug mode setting registers are device global. The HWS has supplied a single pinned VMID (0xf) for MAP_PROCESS for debug purposes. To pin the VMID, the KFD will remove the VMID from the HWS dynamic VMID allocation via SET_RESOUCES so that a debugged process will never migrate away from its pinned VMID. The KFD is responsible for reserving and releasing this pinned VMID accordingly whenever the debugger attaches and detaches respectively.

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.
