ChibiOS Free Embedded RTOS

Hi,
is there a possibility to set the Interrupt Priority Grouping via a definition to enable the subpriorities for interrupt tail chaining?

I did not see any call to NVIC_SetPriorityGrouping (core_cm4.h).

Thanks

Sub priorities are not used by default, the NVIC is initialized in the port layer or in the OSAL, not necessarily using a CMSIS function.
