[Qemu-devel] [PATCH 0/4] ARM: Add support for a generic PCI Express host bridge

[Alexander Graf]

Linux implements a nice binding to describe a "generic" PCI Express host bridge
using only device tree.

This patch set adds enough emulation logic to expose the parts that are
"generic" as a simple sysbus device and maps it into ARM's virt machine.

With this patch set, we can finally spawn PCI devices on ARM VMs. I was able
to have a fully DRM enabled virtual machine with VGA, e1000 and XHCI (for
keyboard and mouse) up and working.

It's only a small step for QEMU, but a big step for ARM VM's usability.


Happy new year!
