[mdb-discuss] A question about ::regs

[Oliver Yang]

Hi,

I have a question about how to get registers' value on a MP system.

Now, I have 2P system, and I want to get registers' value for each of 
CPU.  But  you know, ::regs  just can get only 1 CPU's general register 
value. How can I get another CPU's register value?
