In DRIVE 6.0, NvGPU is allowed to report only 32-bit metadata to Safety_Services. So, there is no need to have distinct APIs for reporting errors from units like GR, MM, FIFO to SDL unit. All these error reporting APIs will be replaced with a single API. To meet this objective, this patch does the following changes: - Replaces nvgpu_report_*_err with nvgpu_report_err_to_sdl. - Removes the reporting of error messages. - Replaces nvgpu_log() with nvgpu_err(), for error reporting. - Removes error reporting to Safety_Services from nvgpu_report_*_err. However, nvgpu_report_*_err APIs and their related files are not removed. During the creation of nvgpu-mon, they will be moved under nvgpu-rm, in debug builds. Note: - There will be a follow-up patch to fix error IDs. - As discussed in https://nvbugs/3491596 (comment #12), the high level expectation is to report only errors.
