[BUGFIX 0/9] Fix bug 59501 and code improvement for dock driver

[Jiang Liu]

Alexander E. Patrakov <patrakov@gmail.com> reports two bugs related to
dock station support on Sony VAIO VPCZ23A4R. Actually there are at least
four bugs related to Sony VAIO VPCZ23A4R dock support.
1) can't correctly detect hotplug slot for dock state
2) resource leak on undocking
3) resource allocation failure for dock devices
4) one bug in intel_snd_hda driver

The first patch fixes issue 1, and the second patch fixes issue 2.
These two patches, if accepted, should be material for stable branches
too.
Patch 3-9 are code improvement for ACPI and dock driver.

I have found the root cause for issue three, but still working on
solutions, and seems can't be solve in short time. So please help 
to review and test patches for issue 1) and 2) first.

Hi Alexander, could you please help to test the whole patchset?

Jiang Liu (9):
  ACPI, DOCK: initialize dock subsystem before scanning PCI root buses
  ACPIPHP: fix device destroying order issue when handling dock
    notification
  ACPI, DOCK: clean up unused module related code
  ACPI, DOCK: avoid initializing acpi_dock_notifier_list multiple times
  ACPI, DOCK: kill redundant spin lock in dock device object
  ACPI, DOCK: mark initialization functions with __init
  ACPI, DOCK: simplify implementation of dock_create_acpi_device()
  ACPI: introduce several helper functions
  ACPI: use new helper functions to simpilify code

[BUGFIX 1/9] ACPI, DOCK: initialize dock subsystem before scanning PCI root buses

[Jiang Liu]

Changeset "3b63aaa70e1 PCI: acpiphp: Do not use ACPI PCI subdriver
mechanism" causes a regression which breaks ACPI dock support,
please refer to https://bugzilla.kernel.org/show_bug.cgi?id=59501

The root cause is that changeset 3b63aaa70e1 changed the relative
initialization order of ACPI dock subsystem and acpiphp driver,
and acpiphp driver has dependency on ACPI dock subsystem's
initialization result, so that acpiphp can't correctly detect ACPI
dock stations now.

On the other hand, ACPI dock is a built-in driver, so we could
explicitly initialize it before the acpiphp driver is used.

[BUGFIX 2/9] ACPIPHP: fix device destroying order issue when handling dock notification

[Jiang Liu]

Current ACPI glue logic expects that physical devices are destroyed
before destroying companion ACPI devices, otherwise it will break the
ACPI unbind logic and cause following warning messages:
[  185.026073] usb usb5: Oops, 'acpi_handle' corrupt
[  185.035150] pci 0000:1b:00.0: Oops, 'acpi_handle' corrupt
[  185.035515] pci 0000:18:02.0: Oops, 'acpi_handle' corrupt
[  180.013656]  port1: Oops, 'acpi_handle' corrupt
Please refer to https://bugzilla.kernel.org/attachment.cgi?id=104321
for full log message.

Above warning messages are caused by following scenario:
1) acpi_dock_notifier_call() queues a task (T1) onto kacpi_hotplug_wq
2) kacpi_hotplug_wq handles T1, which invokes acpi_dock_deferred_cb()
   ->dock_notify()-> handle_eject_request()->hotplug_dock_devices()
3) hotplug_dock_devices() first invokes registered hotplug callbacks to
   destroy physical devices, then destroys all affected ACPI devices.
   Everything seems perfect until now. But the acpiphp dock notification
   handler will queue another task (T2) onto kacpi_hotplug_wq to really
   destroy affected physical devices.
4) kacpi_hotplug_wq finishes T1, and all affected ACPI devices have
   been destroyed.
5) kacpi_hotplug_wq handles T2, which destroys all affected physical
   devices.

So it breaks ACPI glue logic's expection because ACPI devices are destroyed
in step 3 and physical devices are destroyed in step 5.

Tested on top of 3.10-rc5, with no other patches applied.
Unfortunately, lockdep complains on the second docking attempt in the
initially-undocked case. Please see the attached dmesg output.

I have not tested the initially-docked case yet, will do that in 10 minutes.

Can you please send the whole series to linux-acpi next time?

First, because I believe it should go in through the ACPI tree.  Second,
because it is kind of useful to have all of the patches in context.


Thanks,

Tested. The device list is updated as expected if the radeon driver is
blacklisted and there are no open fds to the audio card.

If radeon is not blacklisted, I hit
https://bugzilla.kernel.org/show_bug.cgi?id=59681 , but it is not a
regression.

How exactly does this depend on [2/9]?  If it doesn't at all, it should go
after [1/9].

Don't we actually need the device IDs?

As a cleanup, it definitely makes sense, but does it fix anything?

Again, this is a *cleanup*, not a fix.  Please don't mix cleanups with fixes,
especially with ones you want to go into 3.10, because the cleanups aren't
3.10 material for sure.

Again, this is not 3.10 material.

And you could easily say "three" instead of "several" in the changelog. :-)

Re: [BUGFIX 9/9] ACPI: use new helper functions to simpilify code

Not 3.10 material.

For now, please *only* send the patches from this series that are *necessary*
to fix the regression.  All of the other related stuff should be sent in a
separate series for 3.11, ideally later (hint: when the essential changes have
been tested and approved).

So it looks like we need to focus on [1-2/9] from this series for now.

the 3) is about pci resource allocation?
because pcibios_add_bus is called too early?

If that is case, we should have something like attached patch for it.

With that, we will not need to worry about _OSC set for 3.10 etc.

Do we need that in all of the places pci_bus_add_devices() is called?

It looks like pci_scan_child_bus() might be a better place for adding this,
or am I overlooking something?

acpiphp and acpi_pci_slot used to get attached when pci devices
get enumerated and pci resources get assigned unallocated...

they some kind of pci drivers to pci bus  (comparing with real pci diver to
pci devices).

in dock case, could be, we just got bus, and do not scan pci devices under it.
then we try to scan dock pci devices too early...

Yeah,  if we could move pcibios_fixup_bus to right place, we can move
bus->is_added setting to same place like we set pci_dev->is_added.

So my question is, did we have this problem before commit 3b63aaa70e1?

If we did, then when did it start?  Or was it present forever?

Would not the solution be to modify it so that it didn't spawn the other
task (T2), but removed the affected physical devices synchronously?

Well, let's just say I'm not a fan of recursive locks.  Is that unavoidable
here?

(3) is https://bugzilla.kernel.org/show_bug.cgi?id=56531

> If that is case, we should have something like attached patch for it.

It does not even compile because the argument of pci_bus_add_devices()
points to a const struct. You can't increment a member of it. And even
if you remove the const from both the declaration and the definition
of that function, the patch doesn't help at all.

Hi Yinghai,
    Seems not related to pcibios_add_bus(). According to my
investigation, the issue is caused by difference in PCI resource
assignment between boot time and runtime hotplug. On x86 platforms,
it respects PCI resource assignment from BIOS and only reassign
resources for unassigned BARs. But with acpiphp, it ignores BIOS
resource assignment and reassign all resources by OS.
    If we have enough resources, reassigning all PCI resources should
work too, but may fail if we are under resource constraints. On the
other handle, current PCI IOMM align algorithm may waste huge MMIO
address space if we have some PCI devices with huge IOMM BAR.
    On this Sony laptop, BIOS allocates limited IOMM resources for
the dock station and the dock station has a gfx which has a 256MB
IOMM BAR. So current acpiphp driver fails to allocate resources
for most devices on the dock station.
     Currently I'm trying to change acpiphp to respect BIOS resource 
assignment by calling pcibios_survey_resource_bus(), as in pci_root.c.
The other way is to change the IOMM resource allocation algorithm,
but obviously it's much more risky of regressions if changing the
algorithm.
Regards!
Gerry

Is it a regression?

that is not going to help, need to increase bridge resource.

please check if BIOS have setup option about hotplug MMIO pad size.

Not sure. But a little concern about check_hotplug_bridge(), it treats
dock station and devices on dock station with _EJD as hot-plug-gable
PCI bus and reserve extra resources for possible hot-adding. But I
think we should only reserve extra resource for dock station, and should
not reserve resource for devices on station with _EJD method.

For the first step, I'm trying to make hotplug case work in the same way 
as boot time. Do you think this patch help?

dmesg with the fixed-up patch on v3.10-rc?

After look at the your dmesg v3.10-rc5, we really should move
pcibios_add_bus down.
as we do have children slots under ....

That is should be...

Yes, it should help. but may need to after pcibios_add_bus move down patch.

otherwise, we could enable children slot and survery them and assign
unassigned for them at first
and then go to parent slots.
that will make children slots survey fails, that is too early and
should be done after parent slots.

can not use use pci_assign_unassigned_bus_resources directly. as bus
could have devices that is there already
before this enable_device and could have driver loaded before.

that is why we have checking
    if (PCI_SLOT(dev->devfn) != slot->device)

oh, it seems we should get enable_slot called children slots before parent slots
finished.
so should not need "pcibios_add_bus move down" patch.

Thanks for reminder.
This a quick solution for prove of concept and it should be OK for
this Sony laptop case.
On the other hand, we may need to enhance 
pci_bus_size_bridges(dev->subordinate) and
pci_bus_assign_resources(bus) to support realloc_list.

The patch helped, thanks. Note: I have tested it together with
pci_move_pcibios_add_bus_down.patch, I don't know yet if
pci_move_pcibios_add_bus_down.patch is needed.

The requested information has been added to
https://bugzilla.kernel.org/show_bug.cgi?id=56531

The changes in pci_move_pcibios_add_bus_down.patch are not needed.

The radeon card in the dock station works after docking and restarting
the X server, and its HD audio device works, too. Just for
completeness, I have tested the CD-ROM drive, the USB adapters and the
Ethernet card - they all work. IOW, everything works after docking.

I did not test undocking, as that would surely hit
https://bugzilla.kernel.org/show_bug.cgi?id=59681 and the hda_intel
bug you mentioned in the first mail in this thread.

Note that, for the initial series of patches, I still don't have any
response to the lockdep warnings in
https://lkml.org/lkml/2013/6/13/398

Sorry, I have lost the track of which patches, on top of 3.10-rc5, I
should include in my testing and which I shouldn't. Could you please
restore my understanding? I.e., please provide a full list of LKML or
Bugzilla links to patches which I should test during the next boot of
the laptop.

Thanks in advance.

As far as I'm concerned, please test these two for now:

https://patchwork.kernel.org/patch/2717851/
https://patchwork.kernel.org/patch/2721271/

They are targeted at the ordering problems only, however, so they won't address
the resource allocation issues you're seeing.

There are some other patches Jiang Liu and Yinghai are working on as far as
I can say, but I'm not sure what their status is at the moment.

Thanks,
Rafael

I think this issue should exist before commit "PCI: acpiphp: Do not use
ACPI PCI subdriver mechanism". It may trace back to the changes to kill
acpi_pci_bind()/acpi_pci_unbind().

Yes, that's the way I'm going to fix this issue.

Yeah, you are right, we encounter other deadlock issue here, as reported

It should have similar effect as patch 2/9, and it will encounter the
same deadlock scenario as 2/9 too.

Now dock driver could only be built as built-in, and it doesn't really
bind to ACPI dock devices, so I think the device ids are not used any
more. Not sure whether any userspace tool has dependency on the device
IDs.

And why exactly?

I'm looking at acpiphp_disable_slot() and I'm not seeing where the
problematic lock is taken.  Similarly for power_off_slot().

It should take the ACPI scan lock, but that's a different matter.

The deadlock scenario is the same:
        hotplug_dock_devices()
                mutex_lock(&ds->hp_lock)
                        dd->ops->handler()
				destroy pci bus
                                	unregister_hotplug_dock_device()
                                        	mutex_lock(&ds->hp_lock)

Well, you didn't answer my question.

And this wasn't particularly helpful.

What about mentioning acpi_pci_remove_bus()?  I don't remember all changes
made recently, sorry.

I see the problem.

ds->hp_lock is used to make both addition and removal of hotplug devices wait
for us to complete walking ds->hotplug_devices.  However, if we are in the
process of removing hotplug devices, we don't need removals to block on
ds->hp_lock (in fact, we don't even want them to block on it).  Conversely, if
we are in the process of adding hotplug devices, we don't want additions to
block on ds->hp_lock.

So, why don't we do the following:

(1) Introduce a 'hotplug_status' field into struct_dock station with possible
    values representing "removal", "addition" and "no action" and a wait queue
    associated with it.  We can use ds->dd_lock to protect that field.

(2) hotplug_status will be modified by hotplug_dock_devices() depending on the
    event.  For example, on eject it will set hotplug_status to "removal".
    Then, after completing the walk, it will reset hotplug_status to
    "no action" and wake up its wait queue.

(3) dock_del_hotplug_device() will check if hotplug_status is "removal" or
    "no_action" and if so, it will just do the removal under ds->dd_lock.  If
    it is "addition", though, it will go to sleep (in the hotplug_status' wait
    queue) until hotplug_dock_devices() wakes it up.

(4) Analogously for dock_add_hotplug_device().

For this to work the "addition" and "deletion" of hotplug devices should better
be implemented as setting and clearing a 'hotplug' flag in
struct dock_dependent_device (instead of using ds->hotplug_devices).

Thanks,
Rafael
