This is the full command line I'm using for virt-9.2 (urls sanitized): ~/qemu/build/qemu-system-aarch64 -m 4g,maxmem=8G,slots=8 -monitor stdio -no-reboot -bios ~/emulator/QEMU_EFI-silent.fd -kernel ~/kernel/arm64_build/arch/arm64/boot/Image.gz -device pcie-root-port,id=root_port1 -device virtio-blk-pci,drive=hd -device virtio-net-pci,netdev=mynet,id=bob -drive if=none,file=~/emulator/debian.qcow2,format=qcow2,id=hd -object memory-backend-ram,size=4G,id=mem0 -netdev type=user,id=mynet,hostfwd=tcp::5555-:22 -qmp tcp:localhost:4445,server=on,wait=off -M virt-9.2,nvdimm=on,gic-version=3,ras=on -cpu max -smp 4 -numa node,nodeid=0,cpus=0-3,memdev=mem0 -append 'earlycon nomodeset root=/dev/vda1 fsck.mode=skip tp_printk maxcpus=4' And this is for virt-9.1: ~/qemu/build/qemu-system-aarch64 -m 4g,maxmem=8G,slots=8 -monitor stdio -no-reboot -bios ~/emulator/QEMU_EFI-silent.fd -kernel ~/kernel/arm64_build/arch/arm64/boot/Image.gz -device pcie-root-port,id=root_port1 -device virtio-blk-pci,drive=hd -device virtio-net-pci,netdev=mynet,id=bob -drive if=none,file=~/emulator/debian.qcow2,format=qcow2,id=hd -object memory-backend-ram,size=4G,id=mem0 -netdev type=user,id=mynet,hostfwd=tcp::5555-:22 -qmp tcp:localhost:4445,server=on,wait=off -M virt-9.1,nvdimm=on,gic-version=3,ras=on -cpu max -smp 4 -numa node,nodeid=0,cpus=0-3,memdev=mem0 -append 'earlycon nomodeset root=/dev/vda1 fsck.mode=skip tp_printk maxcpus=4' I opted to use a shorter version just bolding the difference, as the above are a lot harder to see the differences. > > > > > --- > > > > v2: > > - some whitespace and comment changes > > - patch 3/6 (acpi/ghes: rename the function which gets hw error offsets) > > was merged on the cleanup series. > > > > Mauro Carvalho Chehab (5): > > acpi/ghes: Prepare to support multiple sources on ghes > > acpi/ghes: add a firmware file with HEST address > > acpi/ghes: Use HEST table offsets when preparing GHES records > > acpi/generic_event_device: Update GHES migration to cover hest addr > > acpi/generic_event_device: add logic to detect if HEST addr is > > available > > > > hw/acpi/generic_event_device.c | 30 +++++++ > > hw/acpi/ghes.c | 156 +++++++++++++++++++++++++++++---- > > hw/arm/virt-acpi-build.c | 33 ++++++- > > hw/core/machine.c | 2 + > > include/hw/acpi/ghes.h | 23 +++-- > > 5 files changed, 216 insertions(+), 28 deletions(-) > > > Thanks, Mauro
