From 3fdb6d2e31389db65a71cad25ba907a1306e052b Mon Sep 17 00:00:00 2001 From: Alex Waterman Date: Wed, 25 Oct 2017 09:41:52 -0700 Subject: gpu: nvgpu: Remove Linux headers from mm_gk20a.h Delte the Linux headers and make some modifications to get rid of the minor compilation issues that resulted. - Add to os_linux.h - Delete #if 0 code that "flushed" a buffer in gr_gk20a.c - Delete FLUSH_CPU_DCACHE() macro - Move the cache flush definitions to and include this header in sim_gk20a.c. This file will not be used by QNX so this should be fine. - Add to gp106/bios_gp106.c and gp106/mclk_gp106.c. - Move function to common/linux/dmabuf.h since it is a dmabuf related function and uses a struct device pointer as an argument.
