Hi Hanjun,

Thanks for your hard work on ARM64 PCI host bridge/root complex so far!

The latest version (v7) of the ACPI PCI root common code consolidation
series was posted by Gerry (Jiang Liu) yesterday:

https://lkml.kernel.org/g/1444804182-6596-1-git-send-email-jiang.liu@linux.intel.com

This got me wondering what the status is of the ARM64 specific
hostbridge patch series that has a dependency upon the former. Are you
planning to wait for that series to be accepted or post a newer rebased
version for additional review, or something else?

Thanks very much in advance! :)

Jon.

Sorry for top posting. Can you summarize the OperationRegion issue? I am aware of a few early firmwares that effectively had the producer/consumer type for bridge resources the wrong way around but not of the specific issue. If ASWG confidential I can take it over there.

Tomasz and Lorenzo are discussing about the PCI config based
OperationRegions, which still have no conclusion yet, Lorenzo
started a discussion on ASWG and hope can get some feedback.

Other than that, Tomasz volunteered to cleanup this patch set, I
think we need to rebase on Jiang's v7 patchset which was accepted
By Rafael, of course I will work with Tomasz to prepare those
patches.

Thanks
Hanjun
