What do BSP and AP mean in DMESG?

Hi -

When looking at a dump from DMESG on a board with dual CPUs, it shows
that CPU0 = BSP and CPUs 1-3 = AP.  

Does anyone know what those stand for?

Thank you -
Maximus...

AFAIK these terms are Intel's terminalogy for multi processor stuff.
BSP is something like Base System Processor, which is the processor
which booted the machine, AP is Application processor - which are
the processors which get turned on later. It seems strange that you
have 3 APs in a dual processor system!
