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.

This patch adds support for doing various on-the-fly reset of Goya. The driver supports two types of resets: 1. soft-reset 2. hard-reset Soft-reset is done when the device detects a timeout of a command submission that was given to the device. The soft-reset process only resets the engines that are relevant for the submission of compute jobs, i.e. the DMA channels, the TPCs and the MME. The purpose is to bring the device as fast as possible to a working state. Hard-reset is done in several cases: 1. After soft-reset is done but the device is not responding 2. When fatal errors occur inside the device, e.g. ECC error 3. When the driver is removed Hard-reset performs a reset of the entire chip except for the PCI controller and the PLLs. It is a much longer process then soft-reset but it helps to recover the device without the need to reboot the Host. After hard-reset, the driver will restore the max power attribute and in case of manual power management, the frequencies that were set. This patch also adds two entries to the sysfs, which allows the root user to initiate a soft or hard reset. Reviewed-by:Mike Rapoport <rppt@linux.ibm.com> Signed-off-by:
