[PATCH v1 0/4] Unassigned resource fixes

[PATCH v1 0/4] Unassigned resource fixes

[Bjorn Helgaas]

These are some minor resource fixes related to unassigned PCI BARs.  We
should:

  - Mark BARS as unassigned when we can figure that out
  - Not complain about "overlaps" with unassigned BARs
  - Prevent pci_ioremap_bar() on unassigned BARs
  - Give better error messages when pci_ioremap_bar() fails

I don't think these will actually fix any bugs, other than getting rid of
some annoying messages and improving some others.

Comments welcome.

[PATCH v1 1/4] PNP: Don't check for overlaps with unassigned PCI BARs

[Bjorn Helgaas]

After 0509ad5e1a7d ("PNP: disable PNP motherboard resources that overlap
PCI BARs"), we disable and warn about PNP resources that overlap PCI BARs.
But we assume that all PCI BARs are valid, which is incorrect, because a
BAR may not have any space assigned to it.  In that case, we will not
enable the BAR, so no other resource can conflict with it.

Ignore PCI BARs that are unassigned, as indicated by IORESOURCE_UNSET.

Firmware often leaves PCI BARs unassigned, containing zero.  Zero is a
valid BAR value, so we can't just check for that, but the PCI core can set
IORESOURCE_UNSET when it detects an unassigned BAR by other means.  This
should get rid of many of the annoying messages like this:

  pnp 00:00: disabling [io  0x0061] because it overlaps 0001:05:00.0 BAR 0 [io  0x0000-0x00ff]

[PATCH v1 2/4] PCI: Mark invalid BARs as unassigned

[Bjorn Helgaas]

If a BAR is not inside any upstream bridge window, or if it conflicts with
another resource, mark it as IORESOURCE_UNSET so we don't try to use it.
We may be able to assign a different address for it.

[PATCH v1 3/4] PCI: Show driver, BAR#, and resource on pci_ioremap_bar() failure

[Bjorn Helgaas]

Use dev_warn() to complain about a pci_ioremap_bar() failure so we can
include the driver name, BAR number, and the resource itself.  We could use
dev_WARN() to also get the backtrace as we did previously, but I think
that's more information than we need.

[PATCH v1 4/4] PCI: Fail pci_ioremap_bar() on unassigned resources

[Bjorn Helgaas]

Make pci_ioremap_bar() fail if we're trying to map a BAR that hasn't been
assigned.

Normally pci_enable_device() will fail if a BAR hasn't been assigned, but a
driver can successfully call pci_enable_device_io() even if a memory BAR
hasn't been assigned.  That driver should not be able to use
pci_ioremap_bar() to map that unassigned memory BAR.

This went into Linux tree - and broke my ia64 box in a weird way. It only
sees one of the two disks.  git bisect points to this commit, and reverting
it fixes the problem.

Attached are serial logs from the "bad" boot (tip of Linus tree = b79013b2449c)
and for a "good" boot with this commit reverted.

Thanks for the report, and sorry for breaking you.  I hate to ask for
more after all your work already, but would you mind collecting logs
with "ignore_loglevel"?  We only print the BAR information at
KERN_DEBUG, so it doesn't make it to the console unless you use
ignore_loglevel.

I don't really see how the mptsas device at 83:00.0 worked before;
ACPI didn't tell us about any MMIO apertures in the PCI1 host bridge.
But I'll look closer.

Thanks, Tony.  Can you try with the attached debug patch (old kernel or
new, it doesn't matter)?

We think the host bridge apertures are (note that we didn't find an
MMIO aperture):

  ACPI: PCI Root Bridge [PCI1] (domain 0000 [bus 80-ff])
  pci_bus 0000:80: root bus resource [io  0x9000-0xfffe]
  pci_bus 0000:80: root bus resource [bus 80-ff]

but BIOS set up MMIO windows on the bridges at 80:01.0 and 80:05.0,
and it assigned space for igb and mptsas BARs below those bridges:

  pci 0000:80:01.0: PCI bridge to [bus 81]
  pci 0000:80:01.0:   bridge window [mem 0xa0100000-0xa01fffff]
  pci 0000:81:00.0: reg 0x10: [mem 0xa0160000-0xa017ffff]
  pci 0000:81:00.1: reg 0x10: [mem 0xa0120000-0xa013ffff]

  pci 0000:80:05.0: PCI bridge to [bus 83]
  pci 0000:80:05.0:   bridge window [mem 0xa0000000-0xa00fffff]
  pci 0000:83:00.0: reg 0x14: [mem 0xa0010000-0xa0013fff 64bit]

Prior to c770cb4cb505, we complained about the PCI bridge windows not
being inside a host bridge window, but we enabled the igb and mptsas
devices anyway.  After c770cb4cb505, we don't enable them (you reported
that your disk is broken, and I think those two NICs are also broken).

I don't know whether the BIOS failed to tell us about the MMIO aperture,
or it did tell us and we parsed the _CRS info incorrectly.

Thanks.  Your log shows several descriptors that we currently ignore
because their Producer/Consumer bits are set to "Consumer".   Here's one
that contains the MMIO area used by these igb and mptsas devices:

  host bridge resource 12 length 0x38       ACPI_RESOURCE_TYPE_ADDRESS32
    : 00000000: 00 01 00 01 01 01 00 00 00 00 00 00 00 00 00 00

    : 00000030: 0d 00 00 00 50 00 00 00
  [mem 0xa0000000-0xefffffff]

I think we're about to conclude that the Producer/Consumer bit is useless
and should be ignored.

Can you drop the previous debug patch and try this one?

That producer/consumer thing sounds horribly familiar ... did we venture along
this path before many years ago?

I applied the new patch on top of Linus latest (from this morning
HEAD=6c373ca89399c5a3f7ef210ad8f63dc3437da345) without any
reverts.  System booted OK with both disks online and networking
functional).

New serial log attached.

463eb297401e ("[IA64] respect ACPI producer/consumer flag for PCI root
bridges") from 2005 added this check.  There's also been recent discussion
about Jiang's patches and how to handle that bit in some more generic code
[1].

I think if we strictly follow the spec, it is correct to check the
producer/consumer bit.  If we don't check the bit, we are basically
assuming that all Address Space Resource Descriptors are windows that are
forwarded downstream, and I don't think there's a way for a host bridge to
use those descriptors to describe its own CSR space.

But either we haven't figured out how to interpret producer/consumer
correctly, or BIOSes haven't used it consistently, and we end up with
problems like this one.  So I suspect we'll have to give up and just
ignore the producer/consumer bit.

This looks better ... I think.  Here's the change this patch makes:

   ACPI: PCI Root Bridge [PCI0] (domain 0000 [bus 00-7f])
   acpi PNP0A08:00: host bridge window [io  0x0000-0x0cf7]
   acpi PNP0A08:00: host bridge window [io  0x1000-0x8fff]

   acpi PNP0A08:00: host bridge window [mem 0x50000000-0x9fffffff]
  +acpi PNP0A08:00: host bridge window [mem 0x10000000000-0x100fffffffe]
  +acpi PNP0A08:00: host bridge window [mem 0x10100000000-0x101fffffffe]

  +acpi PNP0A08:00: host bridge window [mem 0x10300000000-0x103fffffffe]

   ACPI: PCI Root Bridge [PCI1] (domain 0000 [bus 80-ff])
   acpi PNP0A08:01: host bridge window [io  0x9000-0xfffe]
  +acpi PNP0A08:01: host bridge window [mem 0xfec40000-0xfec7ffff]
  +acpi PNP0A08:01: host bridge window [mem 0xa0000000-0xefffffff]
  +acpi PNP0A08:01: host bridge window [mem 0x10400000000-0x104fffffffe]
  +acpi PNP0A08:01: host bridge window [mem 0x10500000000-0x105fffffffe]
  +acpi PNP0A08:01: host bridge window [mem 0x10600000000-0x106fffffffe]
  +acpi PNP0A08:01: host bridge window [mem 0x10700000000-0x107fffffffe]

The addition of the [mem 0xa0000000-0xefffffff] window for PCI1, which we
previously ignored, is what makes your igb and mptsas devices work again.

It concerns me a little bit that the BIOS apparently did set the producer
bit for the PCI0 [mem 0x50000000-0x9fffffff] window, but not for any of
the other windows, not even the ones that fit in 32 bits.  But maybe that
inconsistency is just a little BIOS lint that doesn't mean anything.

Anyway, I guess I'll package up this patch and post it.
