I edited https://superuser.com/a/1652392/197867 for factual accuracy - specifically that motherboards are the limiting factor behind VT-d and AMD-Vi support nowadays, not processors.
I ultimately disagree that it’s a factual statement that support for VT-d and AMD-Vi is ultimately up to the motherboard firmware. However, I agree it’s a factor that ultimately, determines if it’s supported. Which is something that I ultimately might add to my answer.
One of the comments the author made explicitly asked me to make the edit instead of commenting, which I was initially reluctant to do because of this reason: that it changed the answer too much
Due to the question being a hot network question, for some inexplicable reason, the answer was attracting users who left less than helpful feedback. I was basically waiting until it stopped being a hot network question.
I'm referring to the last comment I made. All the other comments I made were already resolved and are rightfully cleaned up. But the last comment was not resolved yet
I read it and I disagree with the statement you made. The comment was flagged as unnecessary (since the author of the answer had read it) and since there had already been 46 comments submitted to the answer it was deleted by a moderator.
I made edits (a, b) to reflect this, but it was either reverted or rejected by the author.
I never actually rejected your edits. The community explicitly rejected your edit, I choose NOT, to change the outcome of that particular edit. Although I would have if the community improperly approved that first edit. I explicitly choose to edit the answer after the community approved the second edit, to change one of the statements to my own word, but accepted part of your edit as it was an improvement.
I also made comments instead to point out the inaccuracy (as it appears the author disagrees), but the comments have been mysteriously disappearing (among with a bunch of other comments pointing out inaccuracies in the post).
What's going on?
A question that had no business whatsoever became a hot network question, then several users made inaccurate commentary that spanned dozens of comments, and after that happened the third time I just began to flag any comment that wasn’t explicitly feedback about the answer.
So “what’s going on” is that comment section is a discussion forum and a 46 comment long discussion about a topic is ridiculous and was stopped by the moderators.
I should have just asked for the answer to be frozen from the start, but that would have prevented my ability, to actually improve the answer after it stopped getting attention from users outside of Super User.
While certainly discontinued the list you provided, to conclude VT-d is supported by nearly all processors, is incomplete since my own processor doesn’t support it. It’s only been recently has it started to struggle with the largest AAA games and that is only due to the GPU in that particular system.
Which is the entire reason I will not accept any edit that says the processor supporting (VT-d or AMD-Vi) isn’t at least a factor.
