I encountered a problem that I have on my system, where I cannot resize
the bar because one of the bridges has a
If I take a look at the topology, the GPU shares the memory region with a bridge,
+-[0000:64]-+-00.0-[65-68]----00.0-[66-68]--+-01.0-[67]----00.0
The specific bridge likely causing a failure is:
65:00.0 PCI bridge: Intel Corporation Device e2ff (rev 01) (prog-if 00 [Normal decode])
Flags: bus master, fast devsel, latency 0, IRQ 32, IOMMU group 1
Memory at 382400000000 (64-bit, prefetchable) [size=8M]
....
Which causes upstream bridge 64:00.0 initially to allocate the region
[38fe0000000-38ff0000000) for the GPU, and [382ff0000000..382ff07fffff]
for the bridge device.
Bridge 64 is big enough for 1 BMG with a 32 GB bar and the second 8 MB allocation:
pci_bus 0000:64: resource 9 [mem 0x382000000000-0x382fffffffff window] (64GB window)
The reason for failure is that bridge 65 has a 8 MB memory region assigned,
and previously it was ignored when reallocating.
Failing case:

I'm not 100% this is the correct fix, I don't know why the bridge itself has
a memory region, why the kernel allocates it and when it's supposed to
be used. Not a PCI expert. :-)

You're missing words from here. But I can guess you've that extra BAR on
in-card the bridge.

What does this mean? I don't think it was ever ignored while
reallocating??
Note that kernel has become much more verbose in explaining why things
fail so perhaps the added message is confusing you (they won't appear in
the old kernels).

I don't know why it is there either. Nothing in the portdrv really uses it
for anything. There is patchset somewhere lying around which adds a quirk
that releases the "extra" BAR.

This should check if the bridge window is the same or not.
But it may not be wise to do this for any bridge without any
discrimination.

Thank you, I've taken a look at that patch series. It looks like patch 1/2
would help a lot.
I'm wondering if it will completely fix the issue, it is still possible
that in the same config I have 2 identical cards, where resizing might
work, but when GPU1's VRAM BAR is already bound, it might be unable
to resize GPU2's VRAM BAR for the same reason as this patch.
What would be the best way to handle this case?
Kind regards,
~Maarten Lankhorst

I should one day find time to finish that series, Bjorn didn't like how
the code didn't "disable" BAR.
I did some (unset) work towards placing the BARs outside the bridge
window but my algorithm was quite basic (just found min & max window
addresses and put BAR outside of that range but then I thought maybe I
should add the possiblity for placing the BAR into the gap in the middle to
allow placement of a large BAR in cases where 32-bit mmio blocks low-end +
64-bit mmio range blocking the top of the address space.

It is always possible to find cases where a sibling pins the shared bridge
window in place.

The best way is to size them into the largest possible sizes right from
the beginning. But when doing that, nothing must break (introducing
regressions is not okay) so it kernel must be able to graciously fallback
to smaller sizes when there isn't enough space available for the largest
size.
What makes it complicated is that sizing and assignment are done very much
separately, so retrying with a smaller size is complicated. I'm working
toward this kind of solution but there are various things that have to be
fixed first.

How feasible would it be to add a quirk to resize the bar (or reserve enough
space for max) very early before any allocations are done?
I doubt any user of resizable bar is going to hotplug their GPU's.

I don't think that is viable.
Resizing is way more complicated than touching a single BAR because how
the bridge windows work and how resource sizes interact.
No solution is allowed to cause regressions which could easily happen
_much later_ into the resource allocation (very much after the quirk has
finished). How'd you rollback the size changes the quirk caused at that
point???
What such a quirk would effectively do is make rolling back the size
changes an intractable problem, so any regression would be unfixable
except by piling in more and more hacks which isn't viable way forward.

eGPUs connected over Thunderbolt are hotpluggable (whether the
hotpluggability occurs in practice in those cases is another question
though, or if the eGPU just sits there always connected).
