When the microcode update for the 2nd generation and 3rd generation Intel Core (Sandy Bridge/Ivy Bridge) processors for patching the Spectre and Meltdown vulnerabilities will be available?
Microcode update is required for branch target injection mitigation (Spectre).
Moreoover, for example the Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz (2nd Gen - Sandy Bridge) has also PCID capability, therefore the PCID performance optimization for Meltdown may be applicable.
