Hello,
When upgrading from kernel 5.16.2 to a newer version (tried 5.16.3 and
5.16.10 with unchanged .config), the Kernel fails to detect both my
installed mPCIe WiFi cards in my Turris Omnia (newer version, silver
case, GPIO pins installed again).
I have two Mediatek MT7915 based cards installed. I also tried with one
Atheros at9k and one ath10k based card, yielding the same result. On a
Kernel version newer than 5.16.2, all cards aren't getting recognized
correctly.
Before 5.16.3 I also had to disable PCIe ASPM via boot aragument,
otherwise the WiFi drivers would complain about weird device behaviors
and failing to initialize them, but re-enabling it does not yield any
different results.
I am running Arch Linux ARM, but having compiled those kernels for
myself in order to enable the mt76 driver.
Looking at the boot log, it seems to be related to failing setting up
PCI BAR space:

Hi,
I think you need to include the linux-pci mailing list in your report -
from a quick look at the differences between the two boot logs, this
looks like some generic changes in the PCI layer could be responsible.
Thanks.

FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!

Adding linux-pci as this seems to be a problem in the kernel's PCI layer
as being told on linux-arm-kernel.

Please try this commit, which is headed to mainline today:
https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/commit/?h=for-linus&id=c49ae619905eebd3f54598a84e4cd2bd58ba8fe9
This commit should fix the PCI enumeration problem. If you still have
to disable ASPM, that sounds like a separate problem that we should
also try to debug.

This is different and known issue and **not** related to ASPM. I spend
some time on it, initially I thought it is bug in Atheros cards, but now
I'm in impression that this is issue in Marvell PCIe HW that link
retraining (required step of ASPM) triggers either Link Down or Hot
Reset which triggers another Atheros issue (this one is already
documented in kernel pci quirks code).
I will try to implement some workaround for this but requirement is to
have all new improvements in pci-mvebu.c + pci-aardvark.c drivers... and
review process is slow. So it would not be before all those changes are
reviewed and merged.

Removing "pcie_aspm=off" works for my MT7915E based cards, having had no
issues so far. So it doesn't seem to be an issue with the Marvell
hardware itself at least.
Regarding Atheros cards: I disabled it back then for my Atheros AR9582 &
QCA9880 cards and never re-enabled it when I switched to the MT7915E
cards, which I forgot to mention in my first mail, sorry!
I put those two cards back into the device to test it, and the same
problem occurs why I disabled it back then. The router completely
freezes while booting with this as the last log lines (gathered via serial):
[ 10.400986] ath9k 0000:02:00.0: can't change power state from D3cold
to D0 (config space inaccessible)
[ 10.466924] ath10k_pci 0000:03:00.0: can't change power state from
D3cold to D0 (config space inaccessible)

This seems to be another topic however. I'd be glad to test and try to
debug fixes and / or gather additional information on my hardware
regarding this problem.

That is probably because MT7915E card does not trigger that issue. But
I think issue is really in Marvell hardware.

At this stage there is no link with the card. But kernel does not know
it as there is missing implementation for DLLSC interrupt in pci-mvebu.c
driver. We need DLLSC support for debugging this issue.
For another Marvell driver (pci-aardvark.c) there is already pending
patch for review which adds DLLSC interrupt support:
https://lore.kernel.org/linux-pci/20220220193346.23789-9-kabel@kernel.org/
So on Armada 3720 platforms it is possible to start debugging it.
I have (experimental) DLLSC support prepared also for pci-mvebu.c but it
depends on summary interrupt which is in missing in irq-armada-370-xp.c:
https://git.kernel.org/pub/scm/linux/kernel/git/pali/linux.git/log/?h=pci-mvebu
So without that summary interrupt in irq-armada-370-xp.c driver it is
not possible to get information about it in pci-mvebu.c driver.

That is probably because MT7915E card does not trigger that issue. But
I think issue is really in Marvell hardware.

At this stage there is no link with the card. But kernel does not know
it as there is missing implementation for DLLSC interrupt in pci-mvebu.c
driver. We need DLLSC support for debugging this issue.
For another Marvell driver (pci-aardvark.c) there is already pending
patch for review which adds DLLSC interrupt support:
https://lore.kernel.org/linux-pci/20220220193346.23789-9-kabel@kernel.org/
So on Armada 3720 platforms it is possible to start debugging it.
I have (experimental) DLLSC support prepared also for pci-mvebu.c but it
depends on summary interrupt which is in missing in irq-armada-370-xp.c:
https://git.kernel.org/pub/scm/linux/kernel/git/pali/linux.git/log/?h=pci-mvebu
So without that summary interrupt in irq-armada-370-xp.c driver it is
not possible to get information about it in pci-mvebu.c driver.
