Thus the EF bit in place at the time of the FP switch may -indicate that FP operations are disabled. This occurs on certain task -switches, when the EF bit will be 0 for the outgoing task and thus a fault -will be generated on the first FP operation of the FP context save. - -The remedy for this is to enable FP access as the first step in both the -save and restore of the FP context area. This bit will be subsequently -reloaded by the integer context switch. - -Two of the scenarios which demonstrate this problem are outlined below: - -1. When the first FP task is switched to. The system tasks are not FP and -thus would be unable to restore the FP context of the incoming task. - -2. On a deferred FP context switch.
