[Here's something new, a list of regressions introduced between 2.6.26 and
2.6.27.  We haven't fixed all of them yet and they're still being reported.
Also, they need to be fixed as well as those introduced later (although they
may be considered as "less important").

Quite frankly, I don't know how this is going to work out, but I thought
it's worth trying.  Enjoy! ;-)]

This message contains a list of some regressions introduced between 2.6.26 and
2.6.27, for which there are no fixes in the mainline I know of.  If any of them
have been fixed already, please let me know.

If you know of any other unresolved regressions introduced between 2.6.26
and 2.6.27, please let me know either and I'll add them to the list.
Also, please let me know if any of the entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to
this message with CCs to the people involved in reporting and handling the
issue.

I believe this to be a valid bug report, but there doesn't appear to be
anyone to be interested in working on it.  It can be killed off.
I no longer care about it.

Should be fixed by:

commit fd6149d332973bafa50f03ddb0ea9513e67f4517
Author: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi>
Date:   Thu Oct 23 14:06:35 2008 -0700

    tcp: Restore ordering of TCP options for the sake of inter-operability
    
    This is not our bug! Sadly some devices cannot cope with the change
    of TCP option ordering which was a result of the recent rewrite of
    the option code (not that there was some particular reason steming
    from the rewrite for the reordering) though any ordering of TCP
    options is perfectly legal. Thus we restore the original ordering
    to allow interoperability with/through such broken devices and add
    some warning about this trap. Since the reordering just happened
    without any particular reason, this change shouldn't cost us
    anything.
    
    There are already couple of known failure reports (within close
    proximity of the last release), so the problem might be more
    wide-spread than a single device. And other reports which may
    be due to the same problem though the symptoms were less obvious.
    Analysis of one of the case revealed (with very high probability)
    that sack capability cannot be negotiated as the first option
    (SYN never got a response).

Not sure Rafael -- now Joshua have different type

IIRC, Linus complained that it was ugly and slow to do all those
config space reads, and I have to agree with him.  I'd like it
better if we had some sort of pci_dev "enabled" flag or if we could
make it so the pci_dev resources were invalid when the device is
disabled.

Patch actually seems pretty reasonable to me, though like we discussed
at kernel summit last year, there are places where a 0 resource is
assumed to mean "not assigned".  And clearly we need to do something
here...  Anyone else have better ideas than Bjorn's patch below?

Seems like we do need something, but this patch is kind of a klunky
approach, so I'd like to come up with a better proposal.  I don't
have any better ideas yet, though.

Sorry for having to revive this old thread. In November 2008 I reported
that this issue had been solved for me as a result of 1f98757776ea, but I
now find that was due to faulty testing. (I suspect that changing the BIOS
setting that affects this issue on my Toshiba laptop only takes effect
after a cold boot, not a normal reboot.)

The problem was that with the BIOS setting for "Device config" set to
"Setup by OS", I get 78 messages like:
    pnp 00:08: io resource (0x2e-0x2f) overlaps 0000:00:1f.5 BAR 0 (0x0-0xff), disabling
    pnp 00:08: io resource (0x2e-0x2f) overlaps 0000:00:1f.6 BAR 0 (0x0-0xff), disabling

If the BIOS setting is set to "All Devices", the problem does not occur.

The origin of these messages was bisected to:

    PNP: replace pnp_resource_table with dynamically allocated resources

Below the then proposed patch from Bjorn, rediffed against 2.6.29-rc7.
I've verified that the patch still solves the issue for me. Attached
dmesg output for 2.6.29-rc7 without and with the patch.

Bjorn, could you please consider this patch for inclusion again?

The structural patch for this from Bjorn got NACKed. AFAIK we're still 
waiting for someone (Bjorn?) to decide whether to go with a simpler patch 
from Rene for .27 and to push that.

For me it was possible to work around the issue by changing a BIOS 
setting, but I expect it will still affect others with similar BIOS 
behavior.

cool! Looks like a pretty significant fix, for all sorts of legacy 
devices. Worth backporting?

That seems to nicely match what the BIOS setting does on my laptop.

No problem at all. Works correctly (applied on top of current git).
I don't see any unexpected changes in the dmesg output, so:

The problem seems to be that Frans has some PCI devices that are not
configured by the BIOS, and their BARs contain zero.  A PNP quirk
checks for overlaps of PCI devices and PNP devices, and those zero-
valued BARs of course conflict with the PNP motherboard devices that
describe legacy hardware.

Here's another approach based on section 3.5 of the PCI Firmware spec.
It says:

  Since not all devices may be configured prior to the operating
  system handoff, the operating system needs to know whether a
  specific BAR register has been configured by firmware. The operating
  system makes the determination by checking the I/O Enable, and
  Memory Enable bits in the device's command register, and Expansion
  ROM BAR enable bits. If the enable bit is set, then the corresponding
  resource register has been configured.

So instead of checking whether the BAR contains zero, the patch below
checks the I/O, Mem, and ROM BAR enable bits to determine whether a
BAR is enabled.

Frans, I'm sorry to trouble you again, but could you test this and
make sure it takes care of the "resource overlap" messages you saw?

It should be. The patch listed should be good as far as I'm concerned 
but needs to be pushed by Bjorn as PnP mainatainer. Generally speaking 0 
wouldn't be a _very_ necesarily invalid value it seems so it's maybe not 
very nice.

If someone wants a changelog though, this should do:

===
PNP: avoid checking unitialized BARs for conflicts

Avoid checking a PCI BAR for conflicts if the BIOS left it unitialized.

Reported-by: Frans Pop <elendil@planet.nl>
Signed-off-by: Rene Herman <rene.herman@gmail.com>
===

(Frans: Tested-by?)

Rene.
