Intel FUBAR ... again - Kernel memory leak in nearly every Intel CPU of the last decade (Spectre hits everyone, Meltdown still Intel exclusive)

#1221

Either can’t be bothered, or paid intel sponsorship. I’m not even kidding.

I try to call it out. If AMD (or ARM/Apple/Commodore64/etc.) may be impacted, sure - say they MAY be impacted. Don’t imply otherwise (i.e., “suspect” they are impacted) without any facts or architectural discussion (that AMD or someone more knowledgable could directly respond to or validate) to back it up.

If anything, i’d give AMD the benefit of the doubt, because thus far they’ve shown to be slightly less retarded than intel regarding the performance vs security stuff as demonstrated by meltdown.


#1222

I try not to go conspiracy routes, normally things are just dumb f*cking luck / coincidence.

What I do know is that this suspicion will be harming Amd adoption in data center and it works to intels advantage as it sand bags the opponent.

If there was no ‘suspicion’ then amd would be the cure, but with the suspicion there… people are going to think that swapping platforms doesnt really matter from a security standpoint.

That is why all these articles that use the suspicion word, with no evidence ever presented to back up that suspicion… annoy the f*ck out of me.


#1223

AMD is always called out. Not sure why. So far I see this.


#1224

Periodic reminder that this is a newly discovered class of attacks that have not been considered and new specific exploits of similar general variety will keep coming out because CPUs are staggeringly complex. Don’t expect the end to be in sight.

So seems like intel CPU’s with Hyperthreading is taking a big hit in performance with the 4.20 kernal due to new mitigation. Threadripper looking even better now.


#1226

20+ years of intel sitting on arse with security paying off.


#1227

If only Threadripper will solve the IOMMU situation with the chipset. I want to be able to use separate NICs for each VM.


#1228

If only Threadripper would be more flexible when it comes to choice of o/s instead of catering to Win 10 the way it does.


#1229

Be more specific? Performance gains in the 2990WX are up to 2x windows performance when running Linux.


#1230

I have what some might call an old PC. I can run Win 7, Win 8, even Win XP on it if I wanted to and all 64 bit versions of these at that. Yes, I also run Linux on it and I find that old triple boot comes in handy from time-to-time. I like my options but I don’t like Windows 10. I could run that abomination on this build too but for me, that would be like putting Wallmart budget tires on an old Ferrari. Ain’t gonna happen. So why would I put 'em on a brand new Porsche? Windows 10 or Linux. Those are my choices? Surely AMD can do better than this. A work station should include the ability to use optional operating systems of all kinds, in my opinion.


#1231

Threadripper can run Hackintosh with a Clover patch.

And my way of dealing with Windows 10 is to sandbox it’s networking by running it in a VM and a pfsense VM at the same time, with only the pfsense VM having access to the physical NIC. There’s no use editing the hosts file, there’s hosts definitions hard-coded into the kernel. Using pfsense to block connections is pretty much the only assured way.


#1232

Sure because pumping money into a soon-to-be-EOL OS that doesn’t even get real support from its developers (which BTW need to patch the kernel in the first place, and not AMD) is a smart business choice.

CPUs like this didn’t even really exist in the enterprise when 7 was current, nevermind consumer space where 7 was targeted.

It’s not AMDs job to make every OS to work on it. Sure they will provide support if they are asked for it, but they can hardly contribute kernel code to a closed OS, can they…


#1233

This.

@CHESSTUR, hardware doesn’t support software. It’s the other way around.
Also OT…


#1234

Yeah, okay. So let’s all jump on the Windoze 10 band wagon then coz it’s the only o/s Threadripper will work with. NOT I’m sure there are enough Windoze people out there to make AMD’S BROWN NOSING venture worthwhile but I’m not one of them. Looks like I’m stuck with Spectre/Meltdown until something decent manifests in the realm of hardware.


#1235

I still don’t know how you come to the conclusion TR wouldn’t be Linux compatible.


#1236

I’m not sure I came to that conclusion. In fact, I asked in an earlier post if my only options were Linux or Windows 10. To be honest I’d be happier if I learned that Linux were my only option than seeing AMD embrace Windoze 10 but AMD is no different than Intel… They are there for profit like any other company. I can’t knock them for that. I’m just surprised at how NON-FLEXIBLE TR is. Also if you read the specs by manufacturers who have made boards for TR the only o/s they will say works with the board is Windows 10. Most of them won’t even mention Linux.


#1237

TR is no different to any other CPU in terms of application support.

It’s a new architecture and support will depend on the OS vendor. Very few motherboards explicitly list linux support whether they’re intel, amd or whatever.

As a matter of fact, threadripper runs better on linux than it does on Windows due to scheduler brain damage in windows. But even a brief search with google would have told you that.


#1238

No shit. You know what happens when a publicly traded company is not out for profit, right?

But then:


In what way is it non-flexible?

Because then they would have to provide official support, which a lot of companies just cant considering the sheer amount of distributions.


#1239

I’m starting to wonder if you even own threadripper. It’s fine if you don’t, but maybe make a dedicated thread and address your needs in there if you want an answer. Threadripper can operate in Numa mode, Uma mode, it can overclock higher than first Gen Ryzen, and it’s got 16 cores. Don’t start with me on the non-flexible shit.

Now on to windows 10. Microsoft is in a support cycle for older versions of windows. That means it will make sure your existing system keeps working, but it will not add new features, which includes support for new architectures.

Linux is one of two options here. You’re just being childish.


Windows 10 is not that bad. You must have been watching too much lunduke. Sure it’s got its problems, but it’s actually a pretty solid os.

If you have specific questions or concerns that are productive, I’m happy to help address them.


#1240

Well I would still like my 5Ghz 28 core CPU this year. None of the motherboards have been reviewed either :frowning:
Happy new years eve from Australia :slight_smile:
