[haiku-development] VMWare Graphics Driver Synchronization Needed?

Hi!
The VMWare graphics driver reads and writes ports in device.c.
I am wondering if there is any synchronization code needed?
Is it sufficient to synchronize the code within the functions ReadReg
and WriteReg with a spinlock or should the entire case-blocks that read
and/or write registers within function ControlHook be protected with
a spinlock?
Regards,
Michael
