WebAlso, update the heartbeat to allow such a long pre-emption delay in the final heartbeat period. v2: Add clamping helpers. v3: Remove long timeout algorithm and replace with hard coded value (review feedback from Tvrtko). Also, fix execlist selftest failure and fix bug in compute enabling patch related to pre-emption timeouts. WebMost systems default to the wanted configuration, with the noticeable exception of the STM32 driver library. If you are using an STM32 with the STM32 driver library then ensure all the priority bits are assigned to be preempt priority bits by calling NVIC_PriorityGroupConfig ( NVIC_PriorityGroup_4 ); before the RTOS is started.
