Hi all, can someone please show me which is the best practice to lock a read/write to a hardware register. In other words if, in a driver, I want to modify a bit in a HW register, I have to read the register, set/reset the relevant bit and write back the reg. But what can I do to be sure that no other code modifies the register between my read and write? Is spin_lock() suitable for this purpose? Thanks Best regards Luca
