Dump Copy Engine source and destination ring addresses. This is useful information to debug firmware crashes, assertes or hangs over long run assessing the Copy Engine Register status. This also enables dumping CE register status in debugfs Crash Dump file. Screenshot: ath10k_pci 0000:02:00.0: simulating hard firmware crash ath10k_pci 0000:02:00.0: firmware crashed!

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
