2009-02-26 | tracing: implement trace_clock_*() APIs | Ingo Molnar | 1 | -0/+19 | |
Impact: implement new tracing timestamp APIs Add three trace clock variants, with differing scalability/precision tradeoffs: - local: CPU-local trace clock - medium: scalable global clock with some jitter - global: globally monotonic, serialized clock Make the ring-buffer use the local trace clock internally.
