Would be nice of them to provide downloadable firmware updates as they are marked "production". Probably they see that working with motherboard vendors to deploy new microcode via bios updates as the fastest way to mitigate Spectre for the big cloud boys. Quote Link to comment

JorgeB Posted March 29, 2018 Share Posted March 29, 2018 FYI Supermicro just released bios with updated CPU microcode to address ‘Spectre’ variant 2 for most X11 boards. 1 Quote Link to comment
pwm Posted April 6, 2018 Share Posted April 6, 2018 Intel have now announced that they will not (or can not) fix Spectre and Meltdown for a lot of older chips that they had earlier indicated they would release fixes for. Lots of good unRAID chips will not get fixes - Core, Core 2, Bloomfield, Bloomfield Xeon, Clarksfield, Gulftown, Harpertown, Jasper Forest, ... http://newsroom.intel.com/wp-content/uploads/sites/11/2018/04/microcode-update-guidance.pdf http://arstechnica.com/gadgets/2018/04/intel-drops-plans-to-develop-spectre-microcode-for-ancient-chips/ http://www.theregister.co.uk/2018/04/04/intel_spectre_microcode_updates/ Quote Link to comment

It's mainly the big cloud providers with the biggest headaches. Quote Link to comment
pwm Posted May 5, 2018 Share Posted May 5, 2018 As I noted in January when the first Meltdown/Spectre reports were published, I don't think this can be stopped. There have existed side-band attacks just listening to the sound of the power supply - how can a general-purpose processor manage to not leak side-band information unless all speculation is removed? There will always be new statistical methods that can analyze branch prediction/cache misses/... and make deductions about what the CPU is doing or on what data. This is a genie that just can't be put back in the bottle. I think we will need new processors where more sensitive operations are either offloaded to custom hardware or where the processor can turn off the performance mode for critical computations. But that means that in "safe" mode, we'll get glorified 386 chips running way slower than normal mode. Turning off branch-prediction and hiding cache misses means a "safe" processor will have to spend most time stalled. Quote Link to comment

This is one is pretty bad as the only way to fix it for now is to disable hyper-threading. Quote Link to comment

That's a pretty good (and honest) article. FTA: Quote It must be said that no malware, to the best of our knowledge, is exploiting the related Meltdown and Spectre flaws, nor the aforementioned speculative-execution vulnerabilities – partly because mitigations are rolling out across the industry, and partly because there are easier ways to hack people.

chrispeddler Posted June 18, 2019 Share Posted June 18, 2019 Having second thoughts about purchasing Intel. Besides AMD have been catching up and made good processors specially for gaming. Quote Link to comment
