Itcollects detailed information about software execution and records it as"events" in highly compressed format into DRAM. The events cover informationabout control flow changes of a program, whether branches taken or not,exceptions taken, timing information, cycles elapsed and more. This allowsto reconstruct entire program flow of a given application.This comes with separate machine-dependent tracing backends for tracecollection, trace decoder libraries and an instrumentation tool.Reviewed by: kib (sys/kern bits)Sponsored by: UKRIDifferential Revision: https://reviews.freebsd.org/D40466 List of files: /freebsd/sys/modules/hwt/Makefile Thu, 03 Jul 2025 15:10:45 +0200 Ruslan Bukin <br@FreeBSD.org>
