From b42fb7ba26b565f93118fbdd9e17b42ee6144c5e Mon Sep 17 00:00:00 2001 From: Deepak Nibade Date: Tue, 14 Nov 2017 06:43:28 -0800 Subject: gpu: nvgpu: move vgpu code to linux Most of VGPU code is linux specific but lies in common code So until VGPU code is properly abstracted and made os-independent, move all of VGPU code to linux specific directory Handle corresponding Makefile changes Update all #includes to reflect new paths Add GPL license to newly added linux files Jira NVGPU-387 Change-Id: Ic133e4c80e570bcc273f0dacf45283fefd678923 Signed-off-by: Deepak Nibade Reviewed-on: https://git-master.nvidia.com/r/1599472 GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom Reviewed-by: mobile promotions Tested-by: mobile promotions --- drivers/gpu/nvgpu/vgpu/dbg_vgpu.c | 216 -------------------------------------- 1 file changed, 216 deletions(-) delete mode 100644 drivers/gpu/nvgpu/vgpu/dbg_vgpu.c (limited to 'drivers/gpu/nvgpu/vgpu/dbg_vgpu.c') diff --git a/drivers/gpu/nvgpu/vgpu/dbg_vgpu.c b/drivers/gpu/nvgpu/vgpu/dbg_vgpu.c deleted file mode 100644 index 4879c2eb..00000000 --- a/drivers/gpu/nvgpu/vgpu/dbg_vgpu.c +++ /dev/null @@ -1,216 +0,0 @@ -/* - * Copyright (c) 2015-2017, NVIDIA CORPORATION.
