Debugging the PRM

Purpose

Use the provided KTrace and BTrace macros to debug your PRM implementation.

Introduction

These kernel services allow you to generate and capture trace information in a manner designed to minimise the impact on a running system.

Using KTrace

Use the KTRACE macro with KRESMANAGER for debug print messages in the code.

__KTRACE_OPT(KRESMANAGER,Kern::Printf(">DH4PowerResourceController::DoInitController\n”))

Using the kernel trace tool

The BTRACE category, TCategory::EResourceManager, and a number of sub categories are defined and used to trace the progress of all operations on the PRM. All tracing sub categories are wrapped with a macro definition. Implement macro definitions in e32\include\drivers\rescontrol_trace.h to replace BTrace with other tracing methods.
