the PRM PSL</title><shortdesc>This document describes using the test suite for the PRM. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<section id="GUID-A009D3D3-BD1B-40B8-B39D-8F35AD5FCF1E"><title>Purpose</title> <p>Use this test suite to ensure that your

Power Resource Manager implementation runs correctly. </p> <p><b>Introduction</b> </p> <p> <codeph>T_PRMACCTST</codeph> 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 <filepath>e32test/resourceman/acctst/t_prmacctst.cpp</filepath>. </p> <p>The

following tasks are preformed by the test suite: </p> <ul>

<li id="GUID-86D22263-7F34-5F98-A673-909C64F1B929"><p>enumerate all registered

resources, </p> </li>

<li id="GUID-82F19722-C930-55CA-B7DF-B10F23660F5E"><p>check that resources

behave consistently with their properties, </p> </li>

<li id="GUID-37BA8D2B-E226-55EE-99DE-B0DA34D2CD1C"><p>ensure that resources

are reset to their default level when not in use, </p> </li>

<li id="GUID-6A399DB5-996B-503D-AE5B-F89797FB6722"><p>ensure all actual resources

dependencies have been declared (only the extended version of the PRM allows

dependencies). </p> </li>

</ul> <p>To ensure that single-user resources are available to the test application, <codeph>T_PRMACCTST</codeph> is

coupled with a kernel extension, <codeph>D_PRMACCTST</codeph> that takes control

of such resources immediately after the PRM has been initialised. It then

releases the resources when the test application ends. </p> </section>

<section id="GUID-99C0A3AE-5C14-4B6E-9623-FE536E259D08"><title>Using the test suite</title> <p>The instructions to run the

PRM acceptance test suite are as follows: </p> <ol id="GUID-2C3603D2-1CFD-55AF-B2D1-9532A09FA6A3">

<li id="GUID-90FBCCDF-C195-5007-AB19-C2910D7CD1AB"><p>build the test code

in <filepath>e32test/resourceman/acctst</filepath>, </p> </li>

<li id="GUID-5DA609A8-64D1-5533-820D-2115B0412D8A"><p>build a rom for H4HRP

of type <codeph>prmacctst</codeph> in <filepath>e32/rombuild</filepath>: </p> <p><userinput>rom

-v=h4hrp -I=armv5 -b=urel -t=prmacctst</userinput> </p> <p>This command generates

a self-starting ROM. The test output is captured from the default debug port

of the device. </p> </li>

</ol> <p>To build a manual test ROM (so the test application does not run

automatically), use the <codeph>-d=MANUALROM</codeph> option. The usual ESHELL

command prompt will be displayed and the test application can be run by calling <codeph>T_PRMACCTST</codeph>. </p> <p> <b>Note</b>:

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. </p> </section>
