Subject: [RFC 0/5] PCI: Use the private field of pci_host_bridge for ACPI device
Date: Wed, 11 Aug 2021 23:36:14 +0800	[thread overview]
Message-ID: <20210811153619.88922-1-boqun.feng@gmail.com> (raw)

Hi Lorenzo,

As our previous discussion, I make a patchset showing the required
effort if we want to use ->private in pci_host_bridge to store ACPI
device pointer on ARM64. This patchset is mostly for discussion purpose.

This patchset is based onto the v5 of my Hyper-V PCI on ARM64 patchset:

	https://lore.kernel.org/lkml/20210726180657.142727-1-boqun.feng@gmail.com/

, and I've tested it with other code under development to fully enable
Hyper-V virtual PCI on ARM64.

Regards,
Boqun
