<div dir="ltr">Ok.<br>I don't know how to handle that in x86. You should run the POK handler in supervisor mode and then decrease the permission level, when you run the RTEMS handler, to guarantee segregation. You may have to change the interrupt so that instead of calling the RTEMS handler, it returns into it. This will depend on the x86 interrupt model that I don't know (mainly on how you change processor state and how you return from interrupt). Maybe Dr.Joel or Julian can help you with that. <div>
