We cannot call kthread_park() from softirq context, so let's avoid it entirely during the reset. We wanted to suspend the signaler so that it would not mark a request as complete at the same time as we marked it as being in error. Instead of parking the signaling, stop the engine from advancing so that the GPU doesn't emit the breadcrumb for our chosen "guilty" request. v2: Refactor setting STOP_RING so that we don't have the same code thrice Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: Michałt Winiarski <michal.winiarski@intel.com> CC: Michel Thierry <michel.thierry@intel.com> Cc: Jeff McGee <jeff.mcgee@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180516183355.10553-8-chris@chris-wilson.co.uk |

README
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.
