Also, I'm the guy who added support for SandyBrigde (Model 0x2A) and I'm pretty sure uncore support is there (at least for that platform). So, I think it's fair to say "some microarchs lack uncore support" rather than "FreeBSD lacks uncore support".<br /><br />Thanks,<br /><br />DavideDavidehttps://www.blogger.com/profile/02938498639652215650noreply@blogger.com
