Create new dev nodes for device and context profilers. Example of dev nodes on iGPU /dev/nvhost-prof-dev-gpu - device scope profiler /dev/nvhost-prof-ctx-gpu - context scope profiler Add below APIs to open/close above dev nodes : nvgpu_prof_dev_fops_open() nvgpu_prof_ctx_fops_open() nvgpu_prof_fops_release() Add common API nvgpu_prof_fops_ioctl() to handle IOCTL call on these dev nodes. Add IOCTL NVGPU_PROFILER_IOCTL_BIND_CONTEXT to bind the TSG to profiler objects. Add nvgpu_tsg_get_from_file() to retrieve TSG struct pointer from file descriptor. Also store profiler object pointer into TSG struct. Enable NVGPU_SUPPORT_PROFILER_V2_DEVICE capability on gv11b and tu104. Note that this is not yet enabled for vGPU. Keep NVGPU_SUPPORT_PROFILER_V2_CONTEXT capabiity disabled since this will take longer to support. Add new IOCTL NVGPU_PROFILER_IOCTL_UNBIND_CONTEXT so that userspace can explicitly unbind the context and release the resources before closing the profiler descriptor. Add context_init flag to profiler object for book keeping.
