Linus Torvalds, founder of Linux, scolded Intel: “It’s better to face the problem than to do pr.

Linus Torvalds, the founder of Linux, responded that Intel’s processor bugs were not unique to its products. “I think someone inside Intel should have faced up to the problem and worked on it for a long time and admitted that they had a problem with their CPU, instead of confusing it in a pr press release and saying that their product worked as designed.”


Here are some of Linus’ criticisms of Intel:

“A good CPU engineer can ensure that all protected domains do not have such accidents when speculating. Perhaps the instructions for level 1 caching are also typed through CPL. ”


I think someone inside Intel should have faced up to their problem and worked on it for a long time, admitting that they had a CPU problem, rather than blurting out in pr that their products worked as designed.


. This does mean that you should keep in mind when writing these mitigation patches that not all cpus are junk.


Or is Intel saying, “We won’t solve the problem by promising to sell you junk forever?”


If so, maybe we should spend more time with ARM64 people in the future.


Please talk to the management. Because I really only see two possibilities:


1) Intel is never going to solve a problem


2) Fire these people


Which is more likely?

In fact, Linus used to be a fan of the Intel and x86 architectures, which he said were stable, worked well, and, unlike ARM, didn’t need to adapt code for different devices. But Linus has been angered by the recent disclosure of security flaws in Intel processors, Meltdown and Spectre. While it’s fair to say that some of ARM’s chips will also be affected by the ghost, Linus says it’s time to seriously consider switching to ARM architecture.

Intel x86 chips have bugs that support Speculative Execution while running ‘Speculative Execution,’ where ‘disasters’ and’ ghosts’ intrudes to steal user accounts, passwords and other information from memory.

This bug is serious and affects tens of millions, if not billions, of devices. The problem was first identified by Google as “JavaScript code running in the browser can be exploited and intruders can illegally gain access to memory and read user information.” Microsoft said in a blog post.

In tests, researchers have successfully used personal computers’ browsers to hack into user content. In addition, many programs and virtual software, including CHIPS from AMD and ARM, will also be affected. Software providers, chip and cloud companies have issued notifications and patches to remind users of the updates.

It’s unclear how big an impact the bug will have, but it has been shown to reduce device performance by 5% to 30%.

“I think someone inside Intel should have faced up to their problem and worked on it for a long time, and admitted that they had a CPU problem, rather than trying to get it mixed up in pr that their products worked as designed.” Torvalds wrote.
