So each AP has some part of RAM to copy the buffer to?
the way SMP works, the BSP sets up its ram. At that point, the APs can use the BSP ram.
For Opterons where each node has its own RAM this is a little bit more complex, right?
but each AP has access to the BSP ram, or at least that is how I read the code.
I was wondering how you make the APs not conflict in the part of RAM they copy their buffers to. I was also wondering how it would affect interleaving, etc. That kind of thing seems difficult to debug, and is the reason I'd want to see the APs messages.
you give each AP a seperate stack. All that code is in there already.
