455  * struct guc_log_buffer_state - GuC log buffer state
456  *
457  * Below state structure is used for coordination of retrieval of GuC firmware
458  * logs. Separate state is maintained for each log buffer type.
459  * read_ptr points to the location where i915 read last in log buffer and
460  * is read only for GuC firmware. write_ptr is incremented by GuC with number
461  * of bytes written for each log entry and is read only for i915.
462  * When any type of log buffer becomes half full, GuC sends a flush interrupt.
463  * GuC firmware expects that while it is writing to 2nd half of the buffer,
464  * first half would get consumed by Host and then get a flush completed
465  * acknowledgment from Host, so that it does not end up doing any overwrite
466  * causing loss of logs. So when buffer gets half filled & i915 has requested
467  * for interrupt, GuC will set flush_to_file field, set the sampled_write_ptr
468  * to the value of write_ptr and raise the interrupt.
469  * On receiving the interrupt i915 should read the buffer, clear flush_to_file
470  * field and also update read_ptr with the value of sample_write_ptr, before
471  * sending an acknowledgment to GuC. marker & version fields are for internal
472  * usage of GuC and opaque to i915. buffer_full_cnt field is incremented every
473  * time GuC detects the log buffer overflow.
