[Qemu-devel] [PATCH 0/7] hw/pci-bus: Fix PCI bus regression on several archs

[Marcel Apfelbaum <marcel@redhat.com>]

Commit b86eacb (hw/pci: delay bus_master_enable_region initialization) delayed
enabling the 'bus-master' region for PCI devices until 'machine-done' event.
The event registration happens in the PCIBus realize function, however
the PCI bus is not 'realized' *at all* for some machines.

It appears to be a hidden issue revealed by the above commit.
Thanks Mark Cave-Ayland and Leon Alrae for reporting it!

For all the series:

Patch 1: Increase the timeout for the prom-env-test since I encountered random failures.
Patch 2-7: Separate fix for each arch so it will be easier for maintainers to ack.

Thanks,
Marcel
