[Qemu-discuss] MMCONFIG on q35 (qemu 4.0.0)

[Narendra Acharya]

Hi all, I am trying to get the standard q35 machine booting latest alpine linux 
and accessing a PCIe device hooked up to the system.I can get the device 
detected and basic enumeration done by linux but not able to get to the 
extended config space of the device.From what I have read, MMCONFIG is supposed 
to enabled in latest qemu.I am using qemu version 4.0.0, guest linux version is 
4.19.18, alpine x86_64.Are there any switches or options needed to enable 
MMCONFIG on the default q35 host-bridge? The cmd line I am using to start qemu 
is: qemu-system-x86_64 -m 4096 -machine q35 -hda $QCOW_IMG -boot c -D qemu.log 
-display sdl 
Thanks,NMA
