Q: state of pci express hotplug

Q: state of pci express hotplug

[Eric W. Biederman]

Trying to use the current pciehp code, on real hardware in an 
interesting topology (more later) I'm not finding it very satisfactory
at all.  I am up to at least three show stopper bugs and the code
is not doing what I really need it to do, so I am looking at a significant
rewrite patch effort to make this code usable.

Am I unique in thinking there is a lot that needs to be done?
Is there current work in progress to make the pci hotplug work better?

I would like to avoid duplicate work if I can.

I've recently send some fixes against the PCIe port driver which is used by
PCIe hotplug.  In particular, there's a fix that should make the thing work
with MSI-X.

Are your fixes specific to the hotplug driver or do they also affect the PCIe
port driver?

In my personal opinion, there are at least the following items need to
be done for pciehp.

o Possible bugs
  -Current pcie_isr function (interrupt service routine of pciehp) has
   a possibility to get into endless loop in the case that bits in Slot
   Status register is set again immediately after cleared. According to
   the past discussion in the pcihpd-discuss ML, this can happen on the
   power fault detected bit on some platforms.

  -Current pciehp disables software notification of adapter presence
   changed event and MRL changed event when slot is turned off. Because
   of this, there is no way to detect those events on empty slots in the
   current pciehp implementation.

o Missing Features
  -Current pciehp doesn't support Data Link Layer State Changed event
   software notification.
  -No event notification mechanism to userland.
  -When hot-removal request is initiated through the Attention Button
   press, there is no chance to prepare hot-removal (unmount for example).
  -Userland utilities.

o Cleanups
  -slot list is not needed because there is only one slot under the
   switch downstream port.
  -hpc_ops is redundant.
  -some fields in the struct controller, struct slot are redundant.

o Misc
  -I don't think power fault management routines are well tested.
  -I don't think EMI management routines are well tested.

Not sure if this is a bug or error on my part:

a) Cold plug of the PCI express card looks ok ( the devices show up is the sysfs ). 
b)
However hotplug of the same device does not work (it won't show up in
the sysfs and uevents are not sent to udev ). Same issue when ACPI is removed from the kernel build and
modprobe pciehp pciehp_force=1

Posted some details in (can send in more details if needed) :

In the beginning, I'd like to know which hotplug controller driver
manages your hotplug slots. Could you tell me which hotplug controller
drivers add the directories under /sys/bus/pci/slots, with the following
steps?

  (1) Build all your hotplug drivers as kernel modules.
  (2) Modprobe hotplug drivers one by one, and check which drivers add
      directories under /sys/bus/pci/slots. Before trying the next driver,
      please rmmod the previous driver, because there are hotplug slots
      that can be managed by the several drivers. Note that you don't need
      to try fakephp this time. 

Here is an example. My machine has four hotplug slots and those can be
handled by acpiphp or pciehp. I tried acpiphp, pciehp and shpchp on that
machine.

# ls /sys/bus/pci/slots/
# /sbin/modprobe acpiphp
# ls /sys/bus/pci/slots/
1  2  3  4
# /sbin/rmmod acpiphp
# ls /sys/bus/pci/slots/
# /sbin/modprobe pciehp
# ls /sys/bus/pci/slots/
1  2  3  4
# /sbin/rmmod pciehp
# ls /sys/bus/pci/slots/
# /sbin/modprobe shpchp
# ls /sys/bus/pci/slots/

Thanks,
Kenji Kaneshige

Thanks much for the exact steps. Here are the results. Pls let me know if you want me to run them on a different branch or other steps.

Re: Q: state of pci express hotplug

[Kenji Kaneshige]

Hi,

Thank you for sending the information. I understood your
hotplug slot can be handled by acpiphp or pciehp.

Could you give me the following additional information?

o My understanding about the problem is:
  - Bad IRQ happen when you hot-add the device,
  - and the device is not found in the lspci output
  - and the device didn't show up under sysfs
  Am I correct?

o Details about the steps to reproduce the problem.

o Does the problem happen with both acpiphp and pciehp?

o The pciehp's debug output. We can get this as follows.

  # /sbin/modprobe pciehp pciehp_debug
  # dmesg | grep pciehp

Thanks,
Kenji Kaneshige

Tested this with 2.6.28.3 and details below:

   I don't see bad IRQ stack trace anymore, based on the steps you suggested. May be this is because I did not have hotplug driverloaded (and diff kernel build config) ?
  
>  - and the device is not found in the lspci output

   YES

>  - and the device didn't show up under sysfs
>  Am I correct?

   YES
 
> o Details about the steps to reproduce the problem.

  - boot the box with 2.6.28.3
  -   # /sbin/modprobe pciehp pciehp_debug
  - lspci 
  - Insert the PCI express card on the hot swap slot and wait for 2 mins
  - lspci <-- this does not show the PCI express device 
  (The same device shows up in lspci and sysfs during cold boot ) 

> o Does the problem happen with both acpiphp and pciehp?

   That is correct.

Does it behave better with the pciehp_force=1 option?

   modprobe  pciehp pciehp_force=1

Hm, this is merely an observation, but the slot number here seems
wacky compared to the one that acpiphp reports later below.

Did we ever get a dmidecode from this machine?

Also, once you insert the card, what happens if you:

	# echo 1 > /sys/bus/pci/slots/96/power

Does that do anything?

Here we see that ACPI thinks it's slot 2, not 96.

Can you echo a 1 into the power file above?

Could you try below after inserting the device?

With pciehp:

	# echo 1 > /sys/bus/pci/slots/96/power

With acpiphp:

	# echo 1 > /sys/bus/pci/slots/2/power

Thanks,
Kenji Kaneshige

RE: Q: state of pci express hotplug

[Krishna Kothapalli]

Tried  echo power with pciehp, acpiphp. Aslo included dmidecode output. Not much luck yet. Thanks much.

Re: Q: state of pci express hotplug

[Kenji Kaneshige]

Hi,

Thank you for the information. From the information, I understood
both acpiphp and pciehp handles the same slot, and failed powering
on the slot because those drivers detected adapter card didn't
present or MRL opened. But I still don't know why. Could you send
the following addtional information?

(1) The whole 'lspci -vvv' output after booting the system with
    your device inserted (not hot-plugging). Please do it as a
    root user. And please also tell me which entry is corresponding
    to your device in the output.

(2) Try hot-plugging with pciehp again with the following steps
    and give me the result.

    1. # /sbin/modprobe pciehp pciehp_debug
    2. # pr -f /sys/bus/pci/slots/96/*
    3. Insert the adapter card.
    4. # echo 1 > /sys/bus/pci/slots/96/lock
    5. wait for at least 1 second.
    6. # pr -f /sys/bus/pci/slots/96/*
    7. # echo 1 > /sys/bus/pci/slots/96/power
    8. # pr -f /sys/bus/pci/slots/96/*
    9. check if your device is added

Thanks,
Kenji Kaneshige

Apologize for the delay. I tried hotplug of PCI express card on a vendor box (running 2.6.18.x) with PCI express slot.
It looked a lot better. Here is dmesg output as soon a I hotplug and the device shows up in lspci  !!!

So I guess my mother board PCIe slot or BIOS is bad and looking for a looking for a low cost motherboard with working hotplug PCIe slot :)

pciehp: pcie_isr: intr_loc 8
pciehp: pcie_isr: hp_register_read_word SLOT_CTRL with value 28
pciehp: pcie_isr: hp_register_read_word SLOT_STATUS with value 48
pciehp: pciehp:  Presence/Notify input change.
pciehp: Card present on Slot(0003_0003)
pciehp: pcie_isr: Unmask Hot-plug Interrupt Enable

Can you send us some bug reports instead of making us just guess?

I think we all want to help, but that's hard if we don't know
what's broken on your machine.

Thanks.
