From 35ae4194a05d47aa6d79353428f81f2ca47ce90f Mon Sep 17 00:00:00 2001 From: Alex Waterman Date: Thu, 16 Nov 2017 12:56:53 -0800 Subject: gpu: nvgpu: Add translation for NVGPU MM flags Add a translation layer to convert from the NVGPU_AS_* flags to to new set of NVGPU_VM_MAP_* and NVGPU_VM_AREA_ALLOC_* flags. This allows the common MM code to not depend on the UAPI header defined for Linux. In addition to this change a couple of other small changes were made: 1. Deprecate, print a warning, and ignore usage of the NVGPU_AS_MAP_BUFFER_FLAGS_MAPPABLE_COMPBITS flag. 2. Move the t19x IO coherence flag from the t19x UAPI header to the regular UAPI header.
