Loads fine on the 2nd gen i5, Sandy Bridge. Nothing new in the intel release for that CPU as of yet. I think they are focussing on vulns in much newer processors at this point. Mitigation on my hardware running a 64b 5.3.10 kernel in the current LxPupSc remains at:

Code: Select all

l1tf:Mitigation: PTE Inversion
mds:Mitigation: Clear CPU buffers; SMT vulnerable
meltdown:Mitigation: PTI
spec_store_bypass:Mitigation: Speculative Store Bypass disabled via prctl and seccomp
swapgs barriers and __user pointer sanitization
spectre_v2:Mitigation: Full generic retpoline, IBPB: conditional, IBRS_FW, STIBP: conditional, RSB filling
Thanks,
Pups currently in kennel :D Older LxPupSc and X-slacko-4.4 for my users; LxPupSc, LxPupSc64 and upupEF for me. All good pups indeed, and all running savefiles for look'n'feel only. Browsers, etc. solely from SFS.

If I understand correctly this microcode update only works on 64-bit kernels.
To use this on a 32-bit linux build would require a kernel change to a 64-bit kernel?
Just wondering.

Edit: Not wondering any more. See below.

Ozsouth already answered this - so for anyone thats wondering.
