There's an optimisation in the PE setup which skips performing DMA
setup for a PE if we only have bridges in a PE. The assumption being
that only "real" devices will DMA to system memory, which is probably
fair. However, if we start off with only bridge devices in a PE then
add a non-bridge device the new device won't be able to use DMA because
we never configured it.

Fix this (admittedly pretty weird) edge case by tracking whether we've done
the DMA setup for the PE or not. If a non-bridge device is added to the PE
(via rescan or hotplug, or whatever) we can set up DMA on demand.

This also means the only remaining user of the old "DMA Weight" code is
the IODA1 DMA setup code that it was originally added for, which is good.

Alexey, do we need to have the IOMMU API stuff set/clear this flag?

So hotplug does not work on powernv then, right? I thought you tested it
a while ago, or this patch is the result of that attempt? If it is, then

Is ditching IODA1 in the plan? :)

I'd say no as that API only cares if a device is in a PE and for those
the PE DMA setup  optimization is skipped. Thanks,

It mostly works. Just the really niche case of hot plugging a bridge,
then later on hot plugging a device into the same bus which wouldn't
work.

That or separating out the pci_controller_ops for IODA1 and IODA2 so
we can stop any IODA2 specific changes from breaking it. For the most
part keeping around IODA1 support isn't hurting anyone, but I wanted
to re-work how the BDFN->PE assignment works so that we'd delay
assigning a BDFN to a PE until the device is probed. Right now when
we're configuring the PE for a bus we map all 255 devfn's to that PE.
This is mostly fine, but if you do a bus rescan and there's no device
present we'll get a spurious EEH on that PE since the PHB sees that
there's no device responding to the CFG cycle. We stop the spurious
EEH freeze today by only allowing config cycles if we can find a
pci_dn for that bdfn, but I want to get rid of pci_dn.

Mapping each BDFN to a PE after the device is probed is easy enough to
do on PHB3 and above since the mapping is handled by an in-memory
table which is indexed by the BDFN. Earlier PHBs (i.e. IODA1) use a
table of bask & mask values which match on the BDFN, so assigning a
whole bus at once is easy, but adding individual BDFNs is hard. It's
still possible to do in the HW, but the way the OPAL API works makes
it impossible.

Do not you have to have a slot (which is a bridge) for hotplug in the
first place, to hotplug the bridge?

Is IODA1 tested at all these days? Or, is anyone running upstream
kernels anywhere and keeps shouting when it does not work on IODA1? Thanks,

As discussed elsewhere, I missed that it is a non bridge device on the
same bus with previously plugged bridge. Now it all makes sense and

I could but can we fix the issue below before I reboot ?  I don't have a

Firmware is :

I rather not change it if possible.

Do you know when that started happening? I don't think anything
console related has changed in a very long time, but we probably
haven't tested it on p7 in even longer.

5.0.16-100.fc28.ppc64 and 5.4.0-4-powerpc64 have the issue, 
4.16.0-1-powerpc64 doesn't. 

Anyhow, I gave the patchset a try. Here are the kernel logs.

PCI looks fine. System could boot but there are some others
errors.
