Thanks. > Kind of unrelated to this specific patch, but what's our opinion on > turning on pf-fixup by default before the release? As far as the patch here goes, the relationship is very tight. I came to make this patch only while investigating whether we couldn't have Dom0 report the resource (MMIO) ranges early enough for us to not even need such fixing-up. Sadly, as per [1] that turned out pretty much impossible. Which means that while I'm still pretty hesitant of us doing something like this by default, I can't currently see a way around doing so. Hence perhaps yes, we may want (or even need) to turn this on by default. Jan [1] https://lists.xen.org/archives/html/xen-devel/2025-07/msg00446.html
