* gpu: nvgpu: Remove TSG required flagTerje Bergstrom2018-01-02
| | | | | | | | | | | | | | | | | | Remove nvgpu internal flag indicating that TSGs are required. We now require TSGs always. This also fixes a regression where CE channels were back to using bare channels on gp106.

* gpu: nvgpu: remove dependency on linux header for sim_gk20a*Debarshi Dutta2017-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes linux dependencies from sim_gk20a.h under gk20a/sim_gk20a.h. The following changes are made in this patch. 1) Created a linux based structure sim_gk20a_linux that contains a common sim_gk20a struct inside it. The common struct sim_gk20a doesn't contain any linux specific structs. 2) The common struct sim_gk20a contains an added function pointer which is used to invoke gk20a_sim_esc_readl() method. 3) sim_gk20a.c is moved to nvgpu/common/linux along with a new header sim_gk20a.h that contains the definition of struct sim_gk20a_linux. 4) struct gk20a now contains a pointer of sim_gk20a instead of the entire object. The memory for this struct is allocated and initialized during gk20a_init_support() and freed during invocation of gk20_remove_support(). 5) We first obtain the pointer for struct sim_gk20a_linux from the pointer of sim_gk20a using the container_of method in order to work on the struct.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
