On a recent -current: this is not needed anymore, it is part of the defaults now. But you may still compile the kernel with "option TCPHPTS" (until it's added to the defaults too). > Is there a method (yet) for enabling this functionality in various > -RELENG > maybe where one can compile in a vm built for that purpose, then > transferring to the production vm? Copy the kernel which was build according to the acticle from klara systems to your target VM. > Would it be expected to work on arm64? Yes (I use it on an ampere VM in the cloud).
