Bios lvl code is merely a ucode patch to expose more core functionality to be used by programs to mitigate Spectre attacks. And part of the issue with Spectre is that you pretty much have to have every piece of software that hosts other software updated.
Its not just layered defense. Any application that can run 3rd party code is at risk of Spectre based attacks from said code so long as that code can do simple things like get timings for code sections, etc. Bios/OS patches aren't sufficient to prevent that. It requires any potentially...
Actually it isn't really nefarious. Win10 codebase has much more significant support for PCID AND VPCID that significantly mitigate many of the performance impacts of both Spectre and Meltdown fixes.
This is categorically false. Literally the only modern OOO processor that apparently isn't susceptible to meltdown is Zen because of a power saving feature (aka literally no one figured out the issue before it went through Project Zero). Power? Meltdown. Sparc? Meltdown. AMD processors not...
All browsers are updating with mitigation patches against JS exploitation of Spectre/Meltdown exploits. The content of these patches is basically massive increases to the best case timer granularity along with making setting up the attacks more difficult by disabling various call functions...
Um, they don't allow lower privileged processes to access higher privileged data. If they did, a side channel attack wouldn't be required. This definitely falls into the exploit category and not the bug category.
Both Meltdown and Spectre are exploits that target speculative execution...
No, there are multiple chips from multiple vendor using multiple ISA that are vulnerable to at least all three major exploits that have been published.
Problem is that with EPYC, you are limited to VMs of 4 CPUs max. Not just that, allocation boundaries matter a lot too. Basically, you need the workload to fix inside of a CCX, if it doesn't, it takes a significant performance hit.
oh cut the BS. HEDT is literally snake oil to for ignorant people with too much money and not enough sense. The fraction of the market that can actually derive any actual benefit from HEDT is astonishingly small. Esp considering for the same cost you can get a Xeon-D and a 7700k or equiv...
Never confuse a filed patent with an actual product plan. Companies the size of Intel file hundreds to thousands of patents each year only a small number of which have any relation to any product. Companies routinely file patents just to have it published and public, etc.
No, Intel is a...
