a. 对应项目所有的dtsi文件(arch\arm64\boot\dts\qcom)
b. 使能内核dynamic debug log, 抓取kernel log（需要在debug版本上才能抓dynamic
debug log)。
echo ‘file msm-tsens.c +p’ > /sys/kernel/debug/dynamic_debug/control
echo ‘file battery_current_limit.c +p’ > /sys/kernel/debug/dynamic_debug/control
echo ‘file msm_thermal.c +p’ > /sys/kernel/debug/dynamic_debug/control
echo ‘file thermal_core.c +p’ > /sys/kernel/debug/dynamic_debug/control
echo 'file tsens2xxx.c +p' > /sys/kernel/debug/dynamic_debug/control
c. 使能如下trace event, 提供ftrace log
echo thermal:* >> /sys/kernel/debug/tracing/set_event

This document describes a methodology named Hazard Modes & Risk Mitigation Analysis or HMRMA which is based on three principles

Abstract- As the demand for low-cost electronic systemsncreases, increasing wiring density/reducing printed circuiboard (PCB) laver count becomes inevitable. This reality limitsthe PCB routing layer options of high-speed input/output (/O)signals, making it Iore difficult to Ieet the next-generationproduct's performance targets. For example, using denselywired Inicrostrip routing on a PCB helps reduce laver count. bumicrostrip routing suffers from perforinance degradation dueto increased far-end crosstalk(FEXT)."Tabbed lines"havebeen proposed to reduce or eliminate FEXT. In this paper wewill present an introduction fo tabbed lines and their applicationto crosstalk mitigation and impedance management. Followingthat, simulation results are presented showing improvednemory bus performance on densely routed Microstripchannels implemented with tabbed lines
