On schedule-out (CS completion) of a banned context, scrub the context image so that we do not replay the active payload. The intent is that we skip banned payloads on request submission so that the timeline advancement continues on in the background. However, if we are returning to a preempted request, i915_request_skip() is ineffective and instead we need to patch up the context image so that it continues from the start of the next request. v2: Fixup cancellation so that we only scrub the payload of the active request and do not short-circuit the breadcrumbs (which might cause other contexts to execute out of order). v3: Grammar pass Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20191023133108.21401-3-chris@chris-wilson.co.uk
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.
