This patch fix a bug in the driver, where if the TPC or MME remains in non-IDLE even after all the command submissions are done (due to user bug or malicious user), then future command submissions will fail in the context-switch stage and the driver will remain in "stuck" mode. The fix is to do a soft-reset of the device in case the context-switch fails, because the device should be IDLE during context-switch. If it is not IDLE, then something is wrong and we should reset the compute engines. Signed-off-by: Oded Gabbay <oded.gabbay@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
