* gpu: nvgpu: Return gr_ctx_resident from NVGPU_DBG_GPU_IOCTL_REG_OPSAnup Mahindre2018-09-09
| | | | | | | | | | | | | | | | | | NVGPU_DBG_GPU_IOCTL_REG_OPS currently doesn't return if the ctx was resident in engine or not. Regops are broken down into batches of 128 and each batch is executed together. Since there only 32 bits were available in IOCTL args, returning is ctx was resident isn't possible for all batches. Hence return if the ctx was resident for the first batch.

| | | | | | | | | | | | | | | | In the current code, gk20a.h includes io.h which gets directly included in a lot of other files. io.h contains methods which uses a struct gk20a as a parameter leading to a circular dependency between io.h and gk20a.h.

* gpu: nvgpu: remove dependency on linux header for regops_gk20a*Debarshi Dutta2017-11-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* gpu: nvgpu: cleanup of dbg_gpu_gk20aDebarshi Dutta2017-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | This change contains a generic cleanup of linux dependent parts of the dbg_gpu_gk20a.* files. The following changes have been made 1) Moving methods into ioctl_dbg.* inside common/linux/ 2) The structures dbg_session_gk20a and dbg_session_channel_data have been split into two parts. struct device *dev is removed from struct dbg_session_gk20a and instead packed into struct dbg_session_gk20a_linux alongwith dbg_session_gk20a and is moved into ioctl_dbg. dbg_session_gk20a is now rid of any linux dependencies and remains in dbg_gpu_gk20a. Similarly, struct file is removed from struct dbg_session_channel_data and is now packed into struct dbg_session_channel_data_linux alongwith dbg_session_channel_data and is moved into ioctl_dbg. struct dbg_session_channel_data is now rid of linux dependencies and remains in dbg_gpu_gk20a. 3) A callback function is added in order to release the dbg_session_channel_data.
