Due to the wide range of topics covered, the notes got sparser towards the end of the session. I've tried to attribute names against comments but have very likely got things mixed up. Apologies in advance.Was curious if any discussions happened on the RC Emu (config space emulation) as per slide 18 https://schd.ws/hosted_files/xendeveloperanddesignsummit2017/76/slides.pdfPart of this is already posted on the list (ATM for x86 only) but the PCI specification (and therefore the config space emulation) is not tied to any arch: https://lists.xenproject.org/archives/html/xen-devel/2017-06/msg03698.html From the summary, I have a questions on " - Roger: Registering config space with Xen before device discovery will allow the hypervisor to set access traps for certain functionality as appropriate" Traps will do emulation or something else ? Is the config space emulation only for DomU or it for Dom0 as well ? Slide 18 shows only for DomU ? -manish Roger. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx https://lists.xen.org/xen-devel
