Do you have lore links for these handy? I'm not sure exactly what to look at. https://lore.kernel.org/linux-pci/?q=s%3A%22Enable+LTR+for+endpoints+behind+VMD%22 didn't find anything. https://lore.kernel.org/linux-pci/?q=s%3A%22Enable+ASPM+for+links+under+VMD+domain%22 found https://lore.kernel.org/linux-pci/20200821123222.32093-1-kai.heng.feng@canonical.com/t/#u, but it's four years old.
