Date: Sun, 4 Mar 2007 20:14:53 +0100 (MET) From: Patrick McHardy <kaber@...sh.net> To: netdev@...r.kernel.org Cc: Patrick McHardy <kaber@...sh.net>, shemminger@...ux-foundation.org Subject: [RFC IPROUTE 00/08]: Time cleanups + nano-second clock resolution support This patchset consists of four parts: - minor TBF time conversion fix - consolidation of time calculations: consolidate commonly used expressions with the goal of making it easier to audit for integer overflows when increasing the internally used clock resolution. - support for detecting the clock resolution used by the kernel and converting time values as necessary. - finally, increase the internally used clock resolution to nano-seconds These patches have been tested (well, TBF and HFSC) with both old kernels and patched kernels using nano-second resolution. tc/m_estimator.c | 4 +-- tc/m_police.c | 2 - tc/q_cbq.c | 15 +++++++------ tc/q_hfsc.c | 18 +++++++-------- tc/q_htb.c | 4 +-- tc/q_netem.c | 14 +++--------- tc/q_tbf.c | 22 +++++++++---------- tc/tc_cbq.c | 8 +++---- tc/tc_core.c | 61 ++++++++++++++++++++++++++++++++++++++---------------- tc/tc_core.h | 13 +++++++---- tc/tc_estimator.c | 2 - tc/tc_red.c | 2 - tc/tc_util.c | 40 ++++++++++++++++++++++------------- tc/tc_util.h | 7 +++--- 14 files changed, 125 insertions(+), 87 deletions(-) Patrick McHardy: [IPROUTE]: tbf: fix latency printing [IPROUTE]: Use tc_calc_xmittime() where appropriate [IPROUTE]: Introduce tc_calc_xmitsize and use where appropriate [IPROUTE]: Introduce TIME_UNITS_PER_SEC to represent internal clock resolution [IPROUTE]: Replace "usec" by "time" in function names [IPROUTE]: Add sprint_ticks() function and use in CBQ [IPROUTE]: Handle different kernel clock resolutions [IPROUTE]: Increase internal clock resolution to nsec - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
