From 536ec21b565ab1368b53a26d6ec7ed05857f0775 Mon Sep 17 00:00:00 2001 From: Debarshi Dutta Date: Mon, 13 Nov 2017 13:51:48 +0530 Subject: gpu: nvgpu: remove dependency on linux header for regops_gk20a* This patch removes the dependency on the header file "uapi/linux/nvgpu.h" for regops_gk20a.c. The original structure and definitions in the uapi/linux/nvgpu.h is maintained for userspace libnvrm_gpu.h. The following changes are made in this patch. 1) Defined common versions of the NVGPU_DBG_GPU_REG_OP* definitions inside regops_gk20a.h. 2) Defined common version of struct nvgpu_dbg_gpu_reg_op inside regops_gk20a.h naming it struct nvgpu_dbg_reg_op. 3) Constructed APIs to convert the NVGPU_DBG_GPU_REG_OP* definitions from linux versions to common and vice versa. 4) Constructed APIs to convert from struct nvgpu_dbg_gpu_reg_op to struct nvgpu_dbg_reg_op and vice versa. 5) The ioctl handler nvgpu_ioctl_channel_reg_ops first copies from userspace into a local storage based on struct nvgpu_dbg_gpu_reg_op which is copied into the struct nvgpu_dbg_reg_op using the APIs above and after executing the regops handler passes the data back into userspace by copying back data from struct nvgpu_dbg_reg_op to struct nvgpu_dbg_gpu_reg_opi.
