Subject: [Qemu-devel] [PATCH 0/7] hw/pci-bus: Fix PCI bus regression on several archs
Date: Thu, 14 Jul 2016 16:43:39 +0300 [thread overview]
Message-ID: <1468503826-10617-1-git-send-email-marcel@redhat.com> (raw)
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:
Reported-by: Leon Alrae <leon.alrae@imgtec.com>
Reported-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>
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
