For CPX mode, each KFD node has interrupt worker to process ih_fifo to send events to user space. Currently all interrupt workers of same adev queue to same CPU, all workers execution are actually serialized and this cause KFD ih_fifo overflow when CPU usage is high. Use per-GPU unbounded highpri queue with number of workers equals to number of partitions, let queue_work select the next CPU round robin among the local CPUs of same NUMA.

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.
