Subject: [PATCH v3 0/3] PCI: hv: Generify pci-hyperv.c
Date: Mon, 10 Feb 2020 11:39:50 +0800
Message-ID: <20200210033953.99692-1-boqun.feng@gmail.com> (raw)

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
