Sure, here's the original log from at the time when I made the patch. I think it's as verbose as you can get; there's no way I could have used it for the change description. Also I doubt it should matter, but if you need a fresh log instead from 5.17, then I can make one too, but that will take a bit. Let me know if you need me to try anything else too. Thanks, Maciej LILO 22.8 boot: bisect Loading bisect...........................................................

What is the antecedent of "this"? Just the fact that we restore firmware assignments? I think 58c84eda0756 ("PCI: fall back to original BIOS BAR addresses"), which you already reference, is enough to explain that part. Here we just need to explain that we know assigning a BAR that's not inside an upstream bridge's window cannot work, so we might as well fail so we can try something else. > This may work for a device directly on the root bus decoded by the host > bridge only, but for a device behind one or more PCI-to-PCI (or CardBus) > bridges those bridges' forwarding windows have been standardised and > need to be respected, or leaving whatever has been there in a downstream > device's BAR will have no effect as cycles for the addresses recorded > there will have no chance to appear on the bus the device has been > immediately attached to. > > Make sure then for a device behind a PCI-to-PCI bridge that any firmware > assignment is within the bridge's relevant forwarding window or do not > restore the assignment, fixing the system concerned as follows: > > pci_bus 0000:00: max bus depth: 4 pci_try_num: 5 > [...] > pci 0000:06:08.0: BAR 4: no space for [io size 0x0020] > pci 0000:06:08.0: BAR 4: failed to assign [io 0xfce0-0xfcff] > pci 0000:06:08.1: BAR 4: no space for [io size 0x0020] > pci 0000:06:08.1: BAR 4: failed to assign [io 0xfce0-0xfcff] > [...] > pci_bus 0000:00: No. 2 try to assign unassigned res > [...] > pci 0000:06:08.0: BAR 4: no space for [io size 0x0020] > pci 0000:06:08.0: BAR 4: failed to assign [io 0xfce0-0xfcff] > pci 0000:06:08.1: BAR 4: no space for [io size 0x0020] > pci 0000:06:08.1: BAR 4: failed to assign [io 0xfce0-0xfcff] > [...] > pci_bus 0000:00: No. 3 try to assign unassigned res > [...] > pci 0000:06:08.0: BAR 4: assigned [io 0x2000-0x201f] > pci 0000:06:08.1: BAR 4: assigned [io 0x2020-0x203f] I don't think the failures add to the understanding here. > and making device 06:08.0 work correctly. > > Cf. <https://bugzilla.kernel.org/show_bug.cgi?id=16263> > > Signed-off-by: Maciej W.

They've been there since 58c84eda0756, when we didn't look for a parent resource. 351fc6d1a517 ("PCI: Fix starting basis for resource requests") added the pci_find_parent_resource() call, and I think that *should* find the root bus resources if the device is on the root bus. And the root bus resources should already include ioport_resource and iomem_resource if we don't have anything better. So I wonder if we should just always return failure when we don't find a parent resource? Bjorn

My understanding is this is the whole point of this code and said commit. If you look at PR16263 and e.g. comment #12, then you'll see that the case was that we have a PCI-to-PCI bridge device on the root bus (00:04.0) that decodes outside the root bus resource for the purpose of forwarding to its secondary bus and it works. It is fine presumably because the host bridge does additional decoding outside the root bus resource and doesn't tell us about it. However when we try to squeeze device 00:04.0 into space within the root bus resource as we know it, we overrun it and fail the assignment. So the fallback is to revert to what the firmware has left in the BARs, which is outside any PCI resource, causing `pci_find_parent_resource' to fail. But to do such an assignment within our infrastructure, we need to allow assigning outside the root bus resource, which the reference to either `ioport_resource' or `iomem_resource' serves as required. Now that only works for devices on the root bus and not ones behind PCI-to-PCI bridges, where we do have to respect the parent's resource, because a PCI-to-PCI bridge is not allowed to randomly decode ranges beyond ones programmed in standard bridge BARs. > 351fc6d1a517 ("PCI: Fix starting basis for resource requests") added > the pci_find_parent_resource() call, and I think that *should* find > the root bus resources if the device is on the root bus. And the root > bus resources should already include ioport_resource and > iomem_resource if we don't have anything better. Now the description of this commit doesn't really explain (to me anyway) why it is needed or what scenario it addresses that commit 58c84eda0756 didn't by itself handle correctly. My understanding is `pci_find_parent_resource' is expected to always fail in this path as otherwise there shouldn't have been the need to revert to firmware settings and this function wouldn't have been called in the first place. This is because if there indeed is a parent resource the original firmware settings are supposed to fit, then our resource allocator would have found them and used them (or similar ones) rather than failing. So I really do not understand what case this commit is supposed to address. So much for terse change descriptions without actual details of the case addressed! If you are able to infer more or track down an actual discussion with extra information around this commit, then I'm all ears. > So I wonder if we should just always return failure when we don't find > a parent resource? IIUC it would defeat the purpose of commit 58c84eda0756 and is therefore a no-no AFAICT. If you agree with my interpretation, then I'll trim down the change description as you requested (but please bear in mind then it's better to have a little too much information rather than not enough or someone else may end up scratching their head over this change ten years from now just as I do over commit 351fc6d1a517 here) and repost the patch with the code update proper unchanged. Let me know if you have any further questions or comments. Thank you for your review. Maciej

Consequently when the device driver tries to access 06:08.0 according to its designated address range it pokes at an unassigned I/O location, likely subtractively decoded by the southbridge and forwarded to ISA, causing the driver to become confused and bail out: uhci_hcd 0000:06:08.0: host system error, PCI problems? uhci_hcd 0000:06:08.0: host controller process error, something bad happened! uhci_hcd 0000:06:08.0: host controller halted, very bad! uhci_hcd 0000:06:08.0: HCRESET not completed yet! uhci_hcd 0000:06:08.0: HC died; cleaning up if good luck happens or if bad luck does, an infinite flood of messages: uhci_hcd 0000:06:08.0: host system error, PCI problems? uhci_hcd 0000:06:08.0: host controller process error, something bad happened! uhci_hcd 0000:06:08.0: host system error, PCI problems? uhci_hcd 0000:06:08.0: host controller process error, something bad happened! uhci_hcd 0000:06:08.0: host system error, PCI problems? uhci_hcd 0000:06:08.0: host controller process error, something bad happened! [...] making the system virtually unusuable. This is because we have code to deal with a situation from PR #16263, where broken ACPI firmware reports the wrong address range for the host bridge's decoding window and trying to adjust to the window causes more breakage than leaving the BIOS assignments intact. This may work for a device directly on the root bus decoded by the host bridge only, but for a device behind one or more PCI-to-PCI (or CardBus) bridges those bridges' forwarding windows have been standardised and need to be respected, or leaving whatever has been there in a downstream device's BAR will have no effect as cycles for the addresses recorded there will have no chance to appear on the bus the device has been immediately attached to. Make sure then for a device behind a PCI-to-PCI bridge that any firmware assignment is within the bridge's relevant forwarding window or do not restore the assignment, fixing the system concerned as follows: pci_bus 0000:00: max bus depth: 4 pci_try_num: 5 [...] pci 0000:06:08.0: BAR 4: no space for [io size 0x0020] pci 0000:06:08.0: BAR 4: failed to assign [io 0xfce0-0xfcff] pci 0000:06:08.1: BAR 4: no space for [io size 0x0020] pci 0000:06:08.1: BAR 4: failed to assign [io 0xfce0-0xfcff] [...] pci_bus 0000:00: No. 2 try to assign unassigned res [...] pci 0000:06:08.0: BAR 4: no space for [io size 0x0020] pci 0000:06:08.0: BAR 4: failed to assign [io 0xfce0-0xfcff] pci 0000:06:08.1: BAR 4: no space for [io size 0x0020] pci 0000:06:08.1: BAR 4: failed to assign [io 0xfce0-0xfcff] [...] pci_bus 0000:00: No. 3 try to assign unassigned res [...] pci 0000:06:08.0: BAR 4: assigned [io 0x2000-0x201f] pci 0000:06:08.1: BAR 4: assigned [io 0x2020-0x203f] and making device 06:08.0 work correctly.
