[2/7] drm/i915/debug: add new i915_debug.h for debug asserts

Message ID 46e237c35203fd07f9c28afd33de8b5cfbfe2d71.1654261471.git.jani.nikula@intel.com (mailing list archive)

Series drm/i915: i915_drv.h & i915_gem.h header refactoring | expand

Commit Message

Jani Nikula June 3, 2022, 1:05 p.m. UTC 
Move the various GEM_BUG_ON(), GEM_WARN_ON(), etc. debug macros to a
dedicated i915_debug.h file.

Unfortunately, the i915_debug.h needs to be included from some headers
that get included from i915_drv.h, so we don't really get much build
benefits here, other than getting rid of superfluous i915_gem.h
includes.
