Subject: [PATCH 09/10] drm/i915: extract gem/i915_gem_stolen.h from i915_drv.h
Date: Thu,  8 Aug 2019 16:42:48 +0300	[thread overview]
Message-ID: <0141b4e1f1bf2deb65730ce6973863a3a16ab38f.1565271681.git.jani.nikula@intel.com> (raw)
In-Reply-To: <cover.1565271681.git.jani.nikula@intel.com>

It used to be handy that we only had a couple of headers, but over time
i915_drv.h has become unwieldy. Extract declarations to a separate
header file corresponding to the implementation module, clarifying the
modularity of the driver.

Ensure the new header is self-contained, and do so with minimal further
includes, using forward declarations as needed. Include the new header
from i915_drv.h to avoid sprinkling includes all over the place; this
can be changed as a follow-up if necessary.

No functional changes.
