Adding your patch on top of Julien Grall's patch appears to push the Xen boot of my target device (Raspberry PI 4B with Tianocore) further. Still yet to see any output attributable to the Domain 0 kernel though.

The line, "Loading d0 DTB to 0x0000000028000000-0x0000000028000273" seems rather suspicious as I would expect Domain 0 to see ACPI tables, not a device tree. Your (Masami Hiramatsu) patch seems plausible, but things haven't progressed enough for me to endorse it. Looks like something closer to the core of ACPI still needs further work, Julien Grall? -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | ehem+sigmsg@m5p.com PGP 87145445 | ) / \_CS\ | _____ -O #include O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445
