Re: [coreboot] When does AMD release the fam15 spectre microcode updates?

Maybe it just AMD's microcode versioning got messed up and this is indeed the latest microcode despite its' lower number, but the only way to check it - is to test both microcodes for their degree of vulnerability to the Spectres. It does not make much sense to release an outdated microcode,

Hi Rudolf, Please could you try contacting this AMD person again, regarding the problems with this recent microcode update? Because it looks like he noticed your messages since he at least tried to fix, but haven't noticed mine for some reason (regarding the lack of updated 16h microcode; why

Re: [coreboot] When does AMD release the fam15 spectre microcode updates?

If I understood all this correctly, the updated microcodes should be forcing the CPU to do these MSR writes (or the low level action which stands behind them) by default. So that, when you got this updated microcode on your CPU, its already fixed and no further operations are necessary! At the

Hi, I found new microcode here [1], I used cpu00610F01_ver0600111F_2018-03-05_AC55EB96.bin as a microcode for my Trinity family15h CPU. I hacked together a new microcode header which contains the equivalence table etc to be able to load this microcode into the CPU from Linux. dd

Hi, What do you want to protect? If you want to protect the kernel, retpolines are OK on AMD. And you don't need any microcode update. Your CPU needs to have SMEP, otherwise you would need to clear RSB on CPL change (the paper on mentined page says that you need to do that always, but at least

Maybe its' a good idea to write to AMD support regarding this question - please share a reply if you would get an answer. I'm curious about other fam15 CPUs as well, e.g. A10-5750M microcode update would be nice, maybe a request could be more general, e.g. : what is the estimated release date for
