  Természetesen támogatja, fut rajtuk. Ez a kernel része, abba kell SMP támogatást fordítani.
  
  Linux already supports the Core Duo and the Centrino Duo platform very well.
  
  The kernel recognizes the cores and is capable of scaling the frequency independently for each core, as well as sending the CPU's into C-states independently (aka Deeper Sleep)
  
  The Linux kernel is very efficient at multitasking and can be configured (as is default on several major distributions) to be preemptively multitasking
  
  Parallel boot has been implemented on some degree with every distribution, and more and more distributions are taking advantage of the wonderful tools like Bootchart for analyzing boot time. I work primarily for Ubuntu's community, so I'll speak specifically for Ubuntu but it applies to most distributions: We used Bootchart in our past two releases to identify bottlenecks during bootup, and at this point we are optimized to the point that we are hitting all disk IO bottlenecks. Until the entire init system gets smarter, like with initng, our bootup is optimal. On my core duo, it's 40 seconds from power on to a login screen, and a total of 1 minute to a fully ready GNOME desktop. I think that's fairly impressive -- a lot faster than Windows systems and a handful of seconds slower than OSX's insanely fast bootup.
  
  Most of the Core Duo's battery life improvements are hardware based (i.e. having C-states use less power, lower TDP, etc), so Linux already takes advantage of it by doing everything it's been doing on the Pentium M and similar mobile architectures.
  
  Finally, Ubuntu Linux supports all the hardware on the Centrino Duo platform (including the ipw3945 wireless card) out of the box. Several other distributions do or almost do, too.
