Trust that we now have adequate protection over the low level structures via the engine->active.lock to allow ourselves to capture the GPU error state without the heavy hammer of stop_machine(). Sadly this does mean that we have to forgo some of the lesser used information (not derived from the active state) that is not controlled by the active locks. This includes the list of buffers in the ppGTT and pinned globally in the GGTT. Originally this was used to manually verify relocations, but hasn't been required for sometime and modern mesa now has the habit of ensuring that all interesting buffers within a batch are captured in their entirety (that are the auxiliary state buffers, but not the textures). A useful side-effect is that this allows us to restore error capturing for Braswell and Broxton. v2: Use pagevec for a typical arbitrary number of preallocated pages Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190722222847.24178-1-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.
