I need to allocate synch objects in non paged pool, create them on driver load and delete them during unload. What is the best way to do it?

Use Device Extension

From DDK:

For most intermediate and lowest-level drivers, the device extension is the most important data structure associated with a device object. Its internal structure is driver-defined, and it is typically used to:

— Maintain device state information.
— Provide storage for any kernel-defined objects or other system resources, such as spin locks, used by the driver.
— Hold any data the driver must have resident and in system space to carry out its I/O operations.
