From b3446bc0b6fca6cb992667f80a95f8503b6a652a Mon Sep 17 00:00:00 2001 From: Alex Waterman Date: Thu, 7 Sep 2017 15:27:55 -0700 Subject: gpu: nvgpu: Move dma_buf usage from mm_gk20a.c Move most of the dma_buf usage present in the mm_gk20a.c code out to Linux specific code and some commom/mm code. There's two primary groups of code: 1. dma_buf priv field code (for holding comptag data) 2. Comptag usage that relies on dma_buf pointers For (1) the dma_buf code was simply moved to common/linux/dmabuf.c since most of this code is clearly Linux specific. The comptag code was a bit more complicated since there is two parts to the comptag code. Firstly there's the code that manages the comptag memory. This is essentially a simple allocator. This was moved to common/mm/comptags.c since it can be shared across all chips. The second set of code is moved to common/linux/comptags.c since it is the interface between dma_bufs and the comptag memory. Two other fixes were done as well: - Add struct gk20a to the comptag allocator init so that the proper nvgpu_vzalloc() function could be used. - Add necessary includes to common/linux/vm_priv.h.
