Perhaps not at the hardware level, I'm not sure. I downloaded InSpectre (a windows application) which informs me that I had been protected against Spectre and Meltdown attacks through Windows updates. I also used the option to disable the protection, which is how I figured out how much of a performance hit I was taking.
- jcranmer 7y agoThe hardware mitigation at this point is disabling some of the advanced indirect branch prediction in some circumstances (I don't remember the exact set of circumstances). It is nowhere close to disabling all speculative execution.
- gpderetta 7y agoThat's probably meltdown and spectre V2 (i.e. cross process poisoning of indirect branch predictor). There is no hardware/firmware fix yet (and possibly ever) for spectre v1, only software mitigations.
