Gen12 has subtle changes in the reg state context offsets (some fields are gone, some are in a different location), compared to previous Gens. The simplest approach seems to be keeping Gen12 (and future platform) changes apart from the previous gens, while keeping the registers that are contiguous in functions we can reuse. v2: alias, virtual engine, rpcs, prune unused regs v3: use engine base (Daniele), take ctx_bb for all Bspec: 46255 Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Michel Thierry <michel.thierry@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Tested-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> [ickle: Tweaked the GEM_WARN_ON after settling on a compromise with Daniele] Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190906122314.2146-2-mika.kuoppala@linux.intel.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.
