I'll work on improving it and I'll send the V2.
If you have some feedback of the things/fields/structs you think should
remain private to vfio-pci-core please let us know.
Thanks for the effort in the review,

Hi! Abhishek,
My bad! I should check the code base is the latest and follow it.
I'll submit the v2 patch. Thanks for your review.

i will use vfio_pci_core to register to vfio
subsystem and also use the generic PCI functionality exported from it.
Additionally it will add the needed vendor specific logic for HW
specific features such as Live Migration.

This is a preparation patch for separating the vfio_pci driver to a
subsystem driver and a generic pci driver. This patch doesn't change any

changes to the subsystem must be defined as a pre-condition for
this work, we've decided to split the submission for now.

mainly on simulators, but also on FPGA boards (e.g. on KC705 we
can use all of the 1GB onboard DRAM).
In the last few years we've had a few support requests for linux on
xtensa cores with MMU, but AFAICT none of them had to deal with
more than 512MB of onboard memory.

I didn't find the creation of leaf platform devices, maybe I can find
the answer in the missing Patch #5?
Leaf driver is children of partition driver. They are created in

Hi Moritz,
I manually fixed some line breaks. Not sure why outlook is not doing it
properly.
Let me know if it still looks bad to you.

Thanks to Max that started this work! I took his patches and extended a bit.
As Jason suggested, I simplified the "vdpa: split vdpasim to core and
net modules" patch, moving some changes out in small patches.
