Rather than addressing subdevs by a unique index, we give each subdev a type and instance id, and replace the use of bitfields tied to subdev index with other methods. Notable changes: - replace subdev index with subdev type + instance id - engines that turn out to be fused-off (can't detect until later in init) no longer leave dangling pointers around - new subdev/instance additions no longer need to be made in multiple places - ampere engine topology is now being parsed Signed-off-by: Dave Airlie <airlied@redhat.com> From: Ben Skeggs <skeggsb@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/CACAvsv4c_Y923ng0rT1y23wktHHyjEMsusb0=9Z7kQaVbxyPyQ@mail.gmail.com
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.
