This will be used by the accounting code to obtain statistics such as the min / max / average latency of I/O commands. This is based on Benoît's code, originally written last year. Regards, Berto Alberto Garcia (3): timer: Move NANOSECONDS_PER_SECONDS to timer.h timer: Use a single definition of NSEC_PER_SEC for the whole codebase util: Infrastructure for computing recent averages hw/ppc/ppc.c | 2 - hw/ppc/spapr_rtc.c | 3 +- hw/timer/mc146818rtc.c | 1 - hw/usb/hcd-ehci.c | 2 +- include/qemu/throttle.h | 2 - include/qemu/timed-average.h | 58 ++++++++++++ include/qemu/timer.h | 2 + tests/Makefile | 4 + tests/rtl8139-test.c | 10 +-- tests/test-throttle.c | 8 +- tests/test-timed-average.c | 89 ++++++++++++++++++ tests/wdt_ib700-test.c | 15 ++-- util/Makefile.objs | 1 + util/throttle.c | 4 +- util/timed-average.c | 208 +++++++++++++++++++++++++++++++++++++++++++ 15 files changed, 382 insertions(+), 27 deletions(-) create mode 100644 include/qemu/timed-average.h create mode 100644 tests/test-timed-average.c create mode 100644 util/timed-average.c -- 2.1.4
