From: Marcel Apfelbaum
Subject: [Qemu-devel] [PATCH RFC 0/3] qdev: order devices by priority before creating them
Date: Mon, 9 May 2016 20:47:33 +0300

This series aims to allow more devices to be used with '-device'
by sorting the devices based on a predefined creation order flag
before creating them.

Devices like IOMMU need to be created before others, so they can leverage
the DeviceCreationPriority flag introduced by the first patch to DeviceClass.

The second patch sorts the devices by their DeviceCreationPriority
before creating them.

Finally, the last patch demonstrates how it can be used to ensure
the creation of host-bridges before the pci-bridges and pci-bridges before
the others.

I preferred to combine all the priorities into a single enum
to better manage the creation order.

This is an RFC because I only wanted to know if it seems like the right way to 
Comments are appreciated,


Marcel Apfelbaum (3):
  qdev: add device creation priority flag
  vl.c: create devices by their creation priority flag
  hw/pci-bridge: add the corresponding creation priority flag
