gpu: nvgpu: Enabling/disabling FECS trace support
- To enable FECS trace support, nvgpu should set the MSB of the read pointer (MAILBOX1). - The ucode will check if the feature is enabled/disabled before writing a record into the circular buffer. If the feature is disabled, it will not write the record. - If the feature is enabled and the buffer is not allocated, HW will throw a page fault error.
