The ~s command sets which processor is debugged on a multiprocessor system.

In kernel mode, ~s changes the current processor. Do not confuse this command with the ~s (Set Current Thread) command (which works only in user mode), the |s (Set Current Process) command, the ||s (Set Current System) command, or the s (Search Memory) command.

Syntax

~Processor s 

Parameters

Processor

Specifies the number of the processor to debug.

Environment

Comments

You can specify processors only in kernel mode. In user mode, the tilde (~) refers to a thread.

You can immediately tell when you are working on a multiple processor system by the shape of the kernel debugging prompt. In the following example, 0: means that you are debugging the first processor in the computer.

0: kd>

Use the following command to switch between processors:

0: kd> ~1s
1: kd>

Now the second processor in the computer that is being debugged.
