Title:
qemu-system-aarch64: Windows 10 ARM64 BSoD on boot while using
virt-3.0
Status in QEMU:
New
Bug description:
When I emulate a virt-3.0 machine, Windows 10 BSoD on boot, with the
error code being ACPI_BIOS_ERROR(0x000000A5), virt-2.12 boots fine.
Windows Build: 10.0.17134.1
QEMU version: 3.0.0
Commandline: qemu-system-aarch64 -M virt -accel tcg,thread=multi -cpu
cortex-a57 -smp 2 -m 2048 -bios QEMU_EFI.fd -device ramfb -device nec-usb-xhci
-device usb-kbd -device usb-tablet -hda disk.vhd -vnc :0
By the way, the patch to add DBG2 table discussed here
https://lists.gnu.org/archive/html/qemu-devel/2015-09/msg01719.html
works (although minor change is required to adapt to the qemu 3.0.0
code), the table is accepted by Windows (Windows require both DBG2 and
SPCR to be valid for serial kernel debugging to work), so it may help
further diagnosing this issue.
