From c25048bd05a319511aa7386f75e1fae2b2a623c4 Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Wed, 29 Jan 2020 18:05:24 -0500 Subject: vppinfra: improve clocks_per_second convergence Apply exponential smoothing to the clock rate update calculation in clib_time_verify_frequency(), with a half-life of 1 minute and a sampling frequency of 16 seconds. Within 5 minutes or so, the calculation converges With each rate recalculation: reset total_cpu_time based on the kernel timebase delta since vpp started, and the new clock rate Improve the "show clock [verbose]" debug CLI command. BFD echo + echo fail tests marked off until the BFD code can be reworked a bit.
