I'd like to ask you (and all CCed) if it would be possible to explain a bit the goal / functionality behind these patches. By reading the commit descriptions and code, I can understand code-wise what's going on and how this will message the FW on SMT changes. What I couldn't parse is the purpose of this, or in other words, what does it gain for us? Also, why only on Vangogh? Since I don't have the spec I couldn't read and learn myself - apologies if this is somewhat a silly question. Also, if for some reason you cannot respond (like a HW "NDA"), it's fine too. Thanks in advance, Guilherme
