If we enter i915_handle_error() a second time and a global reset is already in progress, we can simply wait for completion of the first reset. Currently we exit early prior to the actual reset being performed -- the worst of both worlds! v2: Plug into the existing reset_queue, and remember that kselftests is playing games with I915_RESET_BACKOFF to prevent hangcheck from screwing up. v3: Rename to i915_reset_device to fit in better with i915_reset_engine Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Cc: Michel Thierry <michel.thierry@intel.com> Reviewed-by: Michel Thierry <michel.thierry@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/20170620095751.13127-2-chris@chris-wilson.co.uk
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.
