What you can learn

How to define a policy to control the events in PSP, so that only interested events are forwarded to Application and unintended events are discarded.

The example code containing Application and CM-Policy is available in PSP/src/example

Usage of CM-Plugin

The policy to control the events are defined in cmPolicy.c and is available in location: \CmPlugin\src\app\common\plugins\cmPolicy.c in specified example.

cmPolicy.c
ClRcT HpiEventFilter(SaHpiSessionIdT session, SaHpiEventT* event, SaHpiRdrT* rdr, SaHpiRptEntryT* rpt) { /* Define the policy to Allow, Block or Change the events here */ if ( /* For Specific condition of Event Ex: event->Severity==SAHPI_MAJOR */) { /* Change the event to required form */ /* event->Severity=SAHPI_MINOR; */ } return CL_OK; }

• HpiEventFilter() will be contain the details of specific event to be handled and specific modification for that event.
