Hi,
This is the first part for virtual PCI support of Hyper-V guest on ARM64. The whole patchset doesn't have any functional change, but only refactors the pci-hyperv.c code to make it more arch-independent.
Previous version: v1: https://lore.kernel.org/lkml/20200121015713.69691-1-boqun.feng@gmail.com/ v2: https://lore.kernel.org/linux-arm-kernel/20200203050313.69247-1-boqun.feng@gmail.com/
Changes since v2:
* Rebased on 5.6-rc1
* Reword commit logs as per Andrew's suggestion.
* It makes more sense to have a generic interface to set the whole msi_entry rather than only the "address" field. So change hv_set_msi_address_from_desc() to hv_set_msi_entry_from_desc(). Additionally, make it an inline function as per the suggestion of Andrew and Thomas.
* Add the missing comment saying the partition_id of hv_retarget_device_interrupt must be self.
* Add the explanation for why "__packed" is needed for TLFS structures.
I've done compile and boot test of this patchset, also done some tests with a pass-through NVMe device.
Suggestions and comments are welcome!
Regards, Boqun
