[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 16/19] tools: tracing: deal with new Credit2 events
more specifically, with: TICKLE_NEW, RUNQ_MAX_WEIGHT,
MIGRATE, LOAD_CHECK, LOAD_BALANCE and PICKED_CPU, and
in both both xenalyze and formats (for xentrace_format).
