When inserting an SD7.0 card to Realtek card reader, it can trigger PCI
slot Link down and causes the following error:

This happens because scheduled pm_runtime_idle() is not cancelled.
So use pm_runtime_barrier() to ensure all devices on the bus stops
runtime power management actions.

This looks like pcr->remap_addr is accessed after it has been iounmap'ed
in rtsx_pci_remove() or before it has been iomap'ed in rtsx_pci_probe().
Is the card reader itself located below a hotplug port and unplugged here?
Or is this about the card being removed from the card reader?
Having full dmesg output and lspci -vvv output attached to a bugzilla
would help to understand what is going on.
Thanks,
Lukas

Ricky, do you know the reason why Link Down happens?

I don't have the hardware so we need Ricky to provide more information here.
Regardless of the cardreader issue, do you have any concern on the patch itself?

Because SD7.0 card is use pcie-nvme driver, reader need to re-link then just do the pcie channel

I don't quite follow. I don't see a pcie-nvme driver in Linus'
current master branch. Which driver are you referring to?
What does "re-link" mean? Rebind to a different driver?

Yes, my concern is that this might be the wrong approach. I would like
to understand what is going on, hence my questions above.

Yes it is card reader unplug itself, because sd7.0 card is not used rtsx_pcr, it use nvme driver

I can only guess here as the dmesg and lspci output I requested
hasn't been provided:
I assume that this card reader may contain a PCIe switch with a
regular SD card reader below a first Downstream Port (which is
hotplug-capable). If an SD express card is inserted, the regular
SD card reader disappears from the Downstream Port and the
inserted card appears as an NVMe drive (possibly below a
second Downstream Port, or below the first Downstream Port).
The commit message is somewhat misleading in that it links the
unhandled page fault to card insertion. That may be the trigger,
but the root cause appears to be that a runtime PM request is
performed asynchronously after the SD card reader has iounmap'ed
pcr->remap_addr.
If that is indeed the root cause (as I suspect), the fix needs to
be placed somewhere else.
pciehp is only one of several hotplug drivers and fixing this only
in pciehp may leave the other hotplug drivers vulnerable to the same
issue.
Unfortunately the information provided so far is insufficient to
recommend a better fix. It would be necessary to debug why the
asynchronous RPM request is not canceled even though rtsx_pci_remove()
runtime resumes the device before iounmap'ing pcr->remap_addr.
Perhaps there's a bug in runtime PM code that causes asynchronous
requests to not be canceled upon a pm_runtime_get_sync()?
Or perhaps a wmb() is necessary in pci_device_remove() after setting
pci_dev->driver = NULL?
Thanks,
Lukas

Card reader replaced with NVMe SSD, third time.
So it took three tries to reproduce the page fault.
Thanks for the log, the issue is a little less murky now.
But it's still unclear what the root cause is and thus
what the proper solution is. I think this needs more
in-depth debugging, see my previous e-mail.
Hope that helps! Thanks,
Lukas

My bad. The pm_runtime_barrier() should be called earlier.
Can you please give the following a try:
