Stefano Stabellini, how much of the Raspberry PI 4B hardware have you observed being operational under Linux on Xen? In particular, have you ever observed operational graphical output from a Raspberry Pi 4B running Xen? Presently I'm using a 5.8 kernel with your patches and haven't seen graphical output under Xen with either boot stack. I've confirmed fully operational graphics without Xen on Tianocore, I've confirmed operational virtual terminals with U-Boot and not Xen. I had been planning to wait a bit before moving to 5.9, but if that is the crucial ingredient I'll move early. -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | ehem+sigmsg@m5p.com PGP 87145445 | ) / \_CS\ | _____ -O #include O- _____ | / _/ 8A19\___\_|_/58D2 7E3D DDF4 7BA6 <-PGP-> 41D1 B375 37D0 8714\_|_/___/5445
