| /** |
| * DOC: KTrace version history, CSF variant |
| * |
| * 1.0: |
| * First version, with version information in the header. |
| * |
| * 1.1: |
| * kctx field is no longer a pointer, and is now an ID of the format %d_%u as |
| * used by kctx directories in mali debugfs entries: (tgid creating the kctx), |
| * (unique kctx id) |
| * |
| * ftrace backend now outputs kctx field (as %d_%u format). |
| * |
| * Add fields group, slot, prio, csi into backend-specific part. |
| * |
| * 1.2: |
| * There is a new class of KCPU traces; with this, a new KCPU column in the |
| * ringbuffer RBUF (mali_trace) between csi and info_val, which is empty |
| * for non-kcpu related traces, and usually displays the KCPU Queue ID and |
| * an extra information value. ftrace also displays these KCPU traces. |
| * |
| * 1.3: |
| * Add a lot of extra new traces. Tweak some existing scheduler related traces |
| * to contain extra information information/happen at slightly different times. |
| * SCHEDULER_EXIT_PROTM now has group information |
