Intel Issues New CPU Microcode for New, Undisclosed Security Updates
- mjevans 3y agoIt's been long enough, can we please just have Intel (YEAR) CPU as a reference rather than the eternally opaque codenames? https://en.wikipedia.org/wiki/Coffee_Lake https://en.wikipedia.org/wiki/Coffee_Lake Intel 2017+ CPUs (Coffee Lake+).
- wtallis 3y agoGoing by year doesn't help when they have more than one microarchitecture in their product line at a time. If their naming conventions were a bit cleaner and they didn't rebadge older chips to prevent the appearance of having holes in their product lineup, then we could almost go by model numbers, but that's definitely not viable. As difficult as they may be to remember, the microarchitecture codenames are the most concise way to unambiguously specify the affected chips.
- scrubs 3y agoAbsolutely. And have you run across the phrase "previously called xxxlake?" [1] was all I could lay my hands on quickly. It's confusing when for ex. you're trying to figure out Intel pmu msr addresses. https://ark.intel.com/content/www/us/en/ark/products/codename/37572/products-formerly-skylake.html https://ark.intel.com/content/www/us/en/ark/products/codenam...

- johnklos 3y agoFor the BSDs and Linux, microcode updates can be loaded by the OS. What about Windows? Are microcode updates made available via Windows, or only via BIOS updates if the system manufacturer decides to make updates? If the latter, what do people do when their system manufacturer doesn't provide updates?
- flangola7 3y agoI don't expect an OS to be able to update hardware

- Khoth 3y agoYes, microcode updates are distributed as part of Windows Update
- usr1106 3y agoPhoronix certainly has strong technical background. However, I am not friend of their sometimes dramatic writing style. I call them the Linux yellow press :) Let's wait and see whether that SA comes and whether it brings something big.
- itvision 3y agoPhoronix is where AMD is infallible and Intel/NVIDIA are evil incarnates. And that results in news pieces like this.
- usr1106 3y agoAh, I don't read it frequently enough to have noticed such bias.
- nebulousthree 3y agoGiven the Linux bent, it makes sense considering AMD's relationship with the open source community relative to Intel's, and to an even greater extent NVIDIA's. You already know this clip: https://www.youtube.com/watch?v=iYWzMvlj2RQ https://www.youtube.com/watch?v=iYWzMvlj2RQ
- ruik 3y agoA nice test would be to compare a "cpuid -1 -r" before and after applied microcode updates. To check if new bit(s) is set somewhere. Worth might be to check if IA32_ARCH_CAPABILITIES contain new bits set as well on some platforms which would indicate they are not affected. Via the NO_xxx flag.
