minifilter callbacks and thread/process/object creation callbacks highest IRQL ?

Hi everyone,

What is the highest possible IRQL that my minifilter callbacks such is IPR_MJ_CREATE callback, and also the thread/process/object creation callbacks, can be called, in a simple non hardware WDM driver?

for example, we know that driverEntry and driverUnload will be called at PASSIVE_LEVEL, and know that dispatch functions can be called at high as DISPATCH_LEVEL. so what about minifilter callbacks and creation callbacks? I am not using WDF.
