I understand that this means that Qubes already deals automatically with all available microcode updates and I do not have to worry about that, which is extremely good. Many thanks!
But another question arises from this very long and interesting thread:
I have three corebooted computers:
KCMA-D8 with Opteron 4284
W520 with Ivy-Bridge
X230
Do you know which one received more microcode updates from Qubes or has less vulnerabilities, so that it can be considered reasonably safer?
Many thanks for reading
