From 80197d2c9daa8e2320cc0b15741904eb3c1b9ba7 Mon Sep 17 00:00:00 2001 From: Konsta Holtta Date: Mon, 5 Jun 2017 17:40:44 +0300 Subject: gpu: nvgpu: split vidmem_is_vidmem As the vidmem_is_vidmem flag has got two separate meanings in one bit, split it in two bits into the enabled() API: Add NVGPU_MM_HONORS_APERTURE bit, which is the same as vidmem_is_vidmem with its original meaning, and use it to test which aperture bits to write to hardware. Add NVGPU_MM_UNIFIED_MEMORY bit, which has the opposite meaning: that the GPU shares the SoC memory. When this flag is false, the GPU has its own local video memory.
