Right now RESET_PCH_HANDSHAKE_ENABLE is enabled all the times inside of intel_power_domains_init_hw() and if PCH is NOP it is unsed in i915_gem_init_hw(). So making skl_pch_reset_handshake() handle both cases and calling it for the missing gens in intel_power_domains_init_hw(). Ivybridge have a different register and bits but with the same objective so moving it too. v2(Rodrigo): - handling IVYBRIDGE case inside intel_pch_reset_handshake() v4(Rodrigo and Ville): - moving the enable/disable decision to callers Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20180918204714.27306-2-jose.souza@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.
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.
