-----Original Message----- From: dri-devel dri-devel-bounces@lists.freedesktop.org On Behalf Of Andi Shyti Sent: Tuesday, December 14, 2021 11:34 AM To: Intel GFX intel-gfx@lists.freedesktop.org; DRI Devel dri-devel@lists.freedesktop.org Cc: Winiarski, Michal michal.winiarski@intel.com; Andi Shyti andi@etezian.org; De Marchi, Lucas lucas.demarchi@intel.com; Chris Wilson chris@chris-wilson.co.uk; Andi Shyti andi.shyti@linux.intel.com Subject: [PATCH v8 11/16] drm/i915/gem: Use to_gt() helper for GGTT accesses
From: Michał Winiarski michal.winiarski@intel.com
GGTT is currently available both through i915->ggtt and gt->ggtt, and we eventually want to get rid of the i915->ggtt one. Use to_gt() for all i915->ggtt accesses to help with the future refactoring.
