I am running an ARM cpu and linux kernel during kernel init on SMP enabled (running with single core in DT) sends SGI to itself while SMP disabled does not. Am puzzled why it does that? AFAIK there is no hyper threading on ARM On Wed, Apr 9, 2014 at 4:51 PM, Kristofer Hallin <kristofer.hallin@gmail.com> wrote:
Using SMP would let your system take advantage of HyperThreading. If you have a fairly decent CPU there is a good chance that your single core have support for HyperThreading which will improve parallelization.
