Ping ;-) Any suggestion or plan on this patchset? Thanks and Regards, Boqun On Mon, Feb 10, 2020 at 11:39:50AM +0800, Boqun Feng wrote:
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/ (local) v2: https://lore.kernel.org/linux-arm-kernel/20200203050313.69247-1-boqun.feng@gmail.com/ (local) 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!
