-QEMU 9.2.0 hangs with 100% CPU when using `-vnc` on Loongarch (3A6000 and 3C6000)
-Description of problem:
-When launching VMs with the `-vnc` parameter (generated by `<graphics type='vnc'>`) on a Loongarch (Loongson 3A6000 or Loongson 3C6000) machine. QEMU process hangs indefinitely with 100% CPU usage, no VNC output.
-Steps to reproduce:
-1. Create a VM using libvirt (Cockpit-Machines or virt-manager).
-2. Configure VNC graphics as follows in libvirt XML, which is provided by Cockpit-Machines by default.
-```xml
-<graphics type='vnc' port='-1' autoport='yes' listen='127.0.0.1'>
-  <listen type='address' address='127.0.0.1'/>
-</graphics>
-```
-3. Start the VM: QEMU process hangs indefinitely with 100% CPU usage, no VNC output.
-Additional information:
-- Removing the `-vnc` parameter from the QEMU command line (via removing <graphics ... In libvirt XML) resolves the issue.
-- The issue appears to stem from changes introduced after QEMU 9.0.1, as downgrading resolves the problem.

-- Full Libvirt VM XML: https://aosc.io/paste/detail?id=6bff0fed-d805-4c36-afb7-d14f29d6313b
-- No activity in `strace` during the hang.
-- GDB backtrace shows the process stuck in `ppoll` (full trace below):
