Testing +the PRM PSL

Purpose

Use this test suite to ensure that your +Power Resource Manager implementation runs correctly.

Introduction

T_PRMACCTST is +a test application that verifies the resources registered with the PSL of +the PRM. For more information refer to the description of individual test +cases in e32test/resourceman/acctst/t_prmacctst.cpp.

The +following tasks are preformed by the test suite:

enumerate all registered +resources,
check that resources +behave consistently with their properties,
ensure that resources +are reset to their default level when not in use,
ensure all actual resources +dependencies have been declared (only the extended version of the PRM allows +dependencies).

To ensure that single-user resources are available to the test application, T_PRMACCTST is +coupled with a kernel extension, D_PRMACCTST that takes control +of such resources immediately after the PRM has been initialised. It then +releases the resources when the test application ends.

Using the test suite

The instructions to run the +PRM acceptance test suite are as follows:

build the test code +in e32test/resourceman/acctst,
build a rom for H4HRP +of type prmacctst in e32/rombuild:

rom +-v=h4hrp -I=armv5 -b=urel -t=prmacctst

This command generates +a self-starting ROM. The test output is captured from the default debug port +of the device.

To build a manual test ROM (so the test application does not run +automatically), use the -d=MANUALROM option. The usual ESHELL +command prompt will be displayed and the test application can be run by calling T_PRMACCTST.

Note: +This test must be run with minimal required components because the test driver +is a kernel extension and takes control of all single-user resources during +its entry point. This test randomly changes the state of all the resources +between a minimum and maximum value. If there are any restrictions on a resources +state change (i.e. the resource state can be only be changed to a certain +value) then that resource should not be registered while running this test.
