Didn't you forgot to mention something important:

Christian König (4):
PCI: Add PCI resource type mask #define
PCI: Add resizable BAR infrastructure
PCI: Add pci_resize_resource() for resizing BARs
x86/PCI: Enable a 64bit BAR on AMD Family 15h (Models 00-1f, 30-3f, 60-7f)

Matching amdgpu patch will come when that one is merged.

What's a BAR in this context?

BARs are PCI resources (memory mapped registers, framebuffer, etc.).

Hello Christian. ;-)))

Can't wait to see it.

Good work!

PS Maybe I find some time (over Christmas) to get some Intel (Nehalem) going.

Sehr nuetzlich fuer nuetzel.
I'm not sure if I have to translate foreign-language to English in order to adhere to the forum rules or abstain from using non-English to begin with at all costs

Offset, stride, and VF device ID are now exposed via sysfs for SR-IOV.

For some reason I thought sysfs was only relevant for Legacy items. Now I gotta reevaluate my understanding of procfs vs. sysfs.
Update: It's a good thing I did, because I had that backwards, kind of ; at least based on my understanding of https://unix.stackexchange.com/quest...ocfs-and-sysfs
