From 8f3875393e7a6bd0fc03afdb1fa99b7e33b71576 Mon Sep 17 00:00:00 2001 From: Konsta Holtta Date: Tue, 14 Mar 2017 13:47:04 +0200 Subject: gpu: nvgpu: abstract away dma alloc attrs Don't use enum dma_attr in the gk20a_gmmu_alloc_attr* functions, but define nvgpu-internal flags for no kernel mapping, force contiguous, and read only modes. Store the flags in the allocated struct mem_desc and only use gk20a_gmmu_free, remove gk20a_gmmu_free_attr. This helps in OS abstraction. Rename the notion of attr to flags. Add implicit NVGPU_DMA_NO_KERNEL_MAPPING to all vidmem buffers allocated via gk20a_gmmu_alloc_vid for consistency. Fix a bug in gk20a_gmmu_alloc_map_attr that dropped the attr parameter accidentally.
