Paul, I thought I said yesterday that i686 PTI was still being developed. First, it has to get to a stage where its developer feels confident it works (his initial post to lkml was when it booted in qemu, at that point he had not tried real hardware). Then it will get reviewed, probably with some changes requested, and eventually it will get into an -rc kernel. After that it can be backported - 4.15 (assuming this all happens before 4.16 is released) and 4.14, then (with luck) backports to 4.9 and 4.4. ĸen -- Truth, in front of her huge walk-in wardrobe, selected black leather boots with stiletto heels for such a barefaced truth. - Unseen Academicals -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
