    Proposed fix to security flaw

    pquiring

      In wake of the massive Intel security flaw many OSes will now leave the kernel spaces out of the TLB which will result in 30%-50% performance hit.  OUCH!!!

       

      Intel should design a new CPU arch where one core is dedicated to kernel and others are user apps.  Then create an inter-core interrupt or something (SMP extension).  These kernel only core(s) could have reduced instruction sets or something.  Maybe 2 kernel cores, 4 user cores, etc.  If unsupported OS runs on CPU then the kernel cores are just unseen.

       

      Just an idea...
