Intel cpu bug. Os patch might reduce perf up to 30% - Page 3

deadite_9 · Jan 4, 2018, 01:44 PM

For those wondering why they're not seeing the update, it supposedly won't install/even be offered if your AV hasn't marked itself compatible by setting a certain registry key.

Quote:

To help prevent stop errors caused by incompatible anti-virus applications, Microsoft is only offering the Windows security updates released on January 3, 2018 to devices running anti-virus software from partners who have confirmed their software is compatible with the January 2018 Windows operating system security update.

If you have not been offered the security update, you may be running incompatible anti-virus software and you should follow up with your software vendor.

Note: Customers will not receive these security updates and will not be protected from security vulnerabilities unless their anti-virus software vendor sets the following registry key:

THis looks very similar to Volkswagen dieselgate ...

Code:

2) Namespace

   Several people including Linus requested to change the KAISER name.

   We came up with a list of technically correct acronyms:

     User Address Space Separation, prefix uass_

     Forcefully Unmap Complete Kernel With Interrupt Trampolines, prefix 
****wit_

   but we are politically correct people so we settled for

    Kernel Page Table Isolation, prefix kpti_

   Linus, your call :)

Insider trading much? So intel knew about this in June, and then he "legally" sells 80% of his holdings just before the news broke. Yeah, that's 100% legit.

Quote:

Some interesting details on the sale now also make sense - Intel CEO Brian Krzanich sold the maximum amount of shares in the company he could, keeping only the mandatory 250,000 minimum shares that come with his position at Intel. In total, Brian Krzanich's sold shares totaled 245,743 shares of stock he owned outright, and 644,135 shares he got from exercising his options. So, the man sold around 80% of his Intel shares while the company (and he himself, surely) knew the flaw would become public knowledge soon enough. There's not even a vestige of shadiness in this whole issue, for sure.

Yes...yes it did. We'll see once the dust has settled and all updates have been rolled out. In the meantime, enjoy those additional 2 frames.

The timeframe is as follows:

June 2017 - Google informs Intel of the flaw.

October 2017 - Intel's CEO draws up new rules regarding selling stocks / ethical bullshit. In regards to offloading stock if something should happen with the company.

November 2017 - Intel's CEO dumps his stock.

January 2018 - Mankind is informed of the greatest security flaw of all time.

It's was 5 months after they were informed. Would it take 5 months for them to realize the severity of the problem? Possibly, but it would seem far more suspicious if Intel's CEO dumps his stock say in June/July.

He's smart waiting those 5 months as to not seem suspicious at the time. It will all come down to what the SEC discovers.

I doubt anything will happen.

Stocks are affected when things go public. Hence, selling stocks off just before being announced.

The sinking will come in two waves, first will be the lawsuits filed against intel, let it be class action or individual business' suing them. And it will probably cost Intel a huge amount of money to settle.

Second will be the CEO being caught up with insider trading. As this will cost the company if it decides to defend the CEO.

Good luck with that. Intel's processors work as intended; it's the OS kernel that is using the processor in an insecure manner to boost performance.

KAC · Jan 5, 2018, 09:09 AM

I don’t always patch bugs on my processors but when I do I make sure AMD is screwed. Love it.

I didn't see the fix in Windows Update on Windows 7, so I had to manually go into my Avira anti-virus software, update it, and then re-check Windows Update to see the January security role-up (KB4056894). The January security role-up patch includes the meltdown fix.

Just wanted to share in case anyone else hits the same snag.

Not overly surprising; unless you are frequently hitting kernel functions and thus suffering the pain of the cache miss/reloads the fix requires you aren't going to notice anything negative; in fact you now have more TLA/page cache space for your process which increases the chances of the VA being in the cache to be translated.

So pretty much what I said earlier ¯\_(ツ)_/¯

KAC · Jan 5, 2018, 11:17 AM

Installed the fix. Still faster than all the bullshite AMD processors.

pax · Jan 5, 2018, 12:11 PM

We wont know the perf hit until intel releases firmware on the 9th. Its still most likely to hit servers/cloud vs desktops tho.

I understand your love for AMD in every thread but if Via pulls a 8 core CPU faster than Intel Coffee lake will you buy it? Will you take a guineea pig / adventurer path .?

Imo the mentality from manageament will take them so far.I feel intel this year at least had so many controversial decisions that i wonder how much the public will swallow.I mean KAC will still buy their CPU's but is "only" 400$ and will not save intel ...

Via is partnering with the Chinese government to develop indigenous processors without NSA backdoors. Which means not one shred of originality as the Chinese only steal technology. No way it's faster than existing designs.

Skynet · Jan 5, 2018, 02:09 PM

Intel is not exactly known for innovation either. In fact their sloppy implementation of AMD64 looks like it could be responsible for the mess they have themselves in.

As for VIA making a competitive processor I'll believe it when it happens.
