Dear Linux folks,
All the way up to QEMU emulator version 5.2.0 (Debian 1:5.2+dfsg-5) and Linux 5.10.13, Linux logs the warning below:
acpi PNP0A03:00: fail to add MMCONFIG information, can't access extended PCI configuration space under this bridge.
One way to reproduce it:
qemu-system-x86_64 -enable-kvm -m 2G -hda /dev/shm/debian.img -kernel /boot/vmlinuz-5.10.0-3-amd64 -initrd /boot/initrd.img-5.10.0-3-amd64 -append root="/dev/sda1 console=ttyS0,115200" -serial stdio
Please find more details and the full log in the Bugzilla issue #211765 [1].
Kind regards,
Paul
