powerpc/powernv/npu: Add a debugfs setting to change ATSD threshold
The threshold at which it becomes more efficient to coalesce a range of ATSDs into a single per-PID ATSD is currently not well understood due to a lack of real-world work loads. This patch adds a debugfs parameter allowing the threshold to be altered at runtime in order to aid future development and refinement of the value.

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. See Documentation/00-INDEX for a list of what is contained in each file. 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.
