The 18c & 22c parts are "paired" meaning 2 SMT4 cores share the same L2 & L3, unlike the 4c and 8c which are "unpaired" meaning each core gets the full L2 and L3 to itself. This is not the same as "fused" (i.e. SMT8 cores) but it is quite likely that the fix will also work for "paired" cores as presumably the issue is sharing cacheable/non-cacheable pathways. Good luck!
I think you're right about the terminology, but yeah, I doubt the IBM docs draw a distinction since those docs are exclusively written for SMT8 users.
I've successfully built a PNOR with IBM's patch; it installed without major issues (I accidentally hosed things the first time I installed it due to the BMC running out of RAM -- protip, don't put multiple PNOR images in OpenBMC /tmp/ -- but power-cycling the BMC fixed that). So far it seems stable, I'll be running it for the next month or so to see if any checkstops happen.
Would you be able to provide more details on which patch? Many thanks
This is the hcode branch I used: https://github.com/JeremyRand/hcode/tree/talos-2019-07-25-master-rebased
As you can see, it's simply a copy of Raptor's hcode, rebased against current upstream IBM hcode (there were no rebase conflicts). The specific bugfix commit is this one: https://github.com/JeremyRand/hcode/commit/ca06a0c996e3b48c02cfb3912dddf7ca23ec4202
I've been running it on my DD2.3 2x18-core Talos II for 2 months, and my DD2.2 2x22-core Talos II for 1 month, and I have had no checkstops on either since applying the patch, nor any new issues. At this point I can recommend that Raptor integrate the bugfix into a new PNOR release. Since the rebase had no conflicts, it should be trivially easy for Raptor to do this.
I may have spoke too soonI get no video when I boot into the os, and the boot console spits this out-

So they have solved the problem of Gnome's slow speed finally, let's just hope that this time they keep it in the next versions too. Can't you tell us anything new about Chromium? We still don't have a valid alternative to Firefox when needed unfortunately... On Debian I have both and they work perfectly because if one of the 2 doesn't work well there's the other and even if it's rare but it can happen...
