Description of problem

Steps to reproduce

1. build qemu: ./configure --prefix=/usr --disable-werror --disable-gtk --target-list="loongarch64-softmmu"
   --enable-debug make -j32

2. get bios and qcow2: wget https://mirrors.wsyu.edu.cn/loongarch/archlinux/images/QEMU_EFI_7.2.fd wget http://pkg.loongnix.cn/loongnix/isos/Loongnix-20.4/Loongnix-20.4.cartoon.gui.loongarch64.en.qcow2

3. start Loongnix ./build/qemu-system-loongarch64
   -m 8G
   -cpu la464
   -machine virt
   -smp 16
   -bios ./QEMU_EFI_7.2.fd
   -serial stdio
   -device virtio-gpu-pci
   -net nic -net user
   -device nec-usb-xhci,id=xhci,addr=0x1b
   -device usb-tablet,id=tablet,bus=xhci.0,port=1
   -device usb-kbd,id=keyboard,bus=xhci.0,port=2
   -device virtio-blk-pci,drive=test -drive if=none,id=test,file=./Loongnix-20.4.cartoon.gui.loongarch64.en.qcow2

4. VNC connect

5. use the system login loongson/Loongson20

6. qemu coredump
