From: Imre Deak Date: Tue, 19 Jan 2016 13:26:32 +0000 (+0200) Subject: drm/i915: Move stolen memory initialization earlier during loading X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a4eba47b25c7077b5b1473b950ae2ff9bcf19fd5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Move stolen memory initialization earlier during loading The only device specific dependency of the stolen memory setup is the MMIO mapping and the stolen memory size. Both are already available in i915_gtt_init(), so move the stolen initialization to there. The clean-up code for i915_gtt_init() is in i915_global_gtt_cleanup(), so move the stolen memory clean-up code there too. This will be needed by an upcoming patch that needs the details of the memory we reserve, but the change is also part of our generic goal to move the initialization of resources with no or little dependencies on other device specific resources towards the beginning of the init sequence.
