Linux 2.6.27-git3: no SD card reader

[J.A. Magallón]

Hi...

More problems with git3. The left SD card reader is not detected on the One.
With a working kernel (distro 2.6.27):

Any ideas ?

-84 is -EILSEQ, which is some kind of bit error. Since you're running a
JMicron controller, I'm guessing that something in your system isn't
handling the higher speed (we forcefully enable highspeed on the
Jmicron controll now).

What machine is this? Have you tested more than one card?

Err, sorry if this is stupid. I can see the card reader even if I don't
load the jmb38x_ms.ko module,just sdhci_pci. I understand that it is needed only if
I want to read memstick type cards. Or not ?
I suppose you refer to 'settings for JMicron hardware in sdhci_pci module'.

I have two (both unknown brands for me, but I write full names fwiw):
- One "MBA Executive HiSpeed SD", 2Gb
- One "takeMS SDHC card Class6",  8Gb

Both give about 10Mb/s on read with hdparm under 2.6.27.

> What machine is this? 

It's an Acer Aspire One. From what I have seen, there are two SD devices.
Both are capable to read SDHC cards, I have switched cards and they work
(or at the moment both are working as backwards-compatible in plain SD
mode, if that even exists...).

I call this half-working because I have to boot with a card inside a slot
to have it detected. If i boot without the card-in, it even dissapears from
lspci. This is just with the left SD inserted:

If I insert a card on the right slot now it has no effect, it does not appear.
I suppose it is PCI hot-plunggin that is not hot nor plugs anything ;).:

The tree after the bridge in 00:1c.0 is gone !!.
I googled about it and someone talked about pciehp_force, but last time
I tried some other devices (ether, could be?) dissapeared.

And now with -git4:

Mmm, looking at the logs I have seen that in 2.6.27 shpchp is loaded
way before sdhci, and in -git4 it loads after it. Can this have
any effect ?

TIA, hope all this gives some light.
If you need full dmesg's, just ask.

I solved this in modprobe.conf:

options sdhci debug_quirks=1

If I uderstood the source, that touches the controller clock on each reset for
the operation to work.

2.6.28-rc2 still doesn't see the card without that option.

And there is another problem, -rc2 doesn't reboot on the One, but that's for
another thread (don't know if it can be related).

That is correct.

Kind of. The JMicron controller supports 50 MHz SD cards, but it
restricted to 25 MHz in the name of higher compatibility.

The SD/SDHC distinction is all software, so the hardware doesn't really
care.

No idea why this occurs. I'd guess some ACPI voodoo. You're going to
have to check with the PCI and/or ACPI guys to figure that part of the
mystery out.

Hmm... I thought you said that it was just the left reader that had
problems? Not both?

Perhaps, but I doubt it. If you rmmod sdhci-pci and modprobe it again
you should have the same behaviour as in .27.

Actually, I think you're just seeing the side effect that the
controller will revert back to the 25 MHz restriction.

This specific problem is what I thought Matthew's acpiphp patch would 
solve - see my comment 
<http://bugzilla.kernel.org/show_bug.cgi?id=11828#c1>.

If I've got this right, then this *specific* issue isnot a regression.

Matthew, if I have confused two similar issues, could you please help by 
explaining the differences?

Thanks
Alan

You're correct. On any released version of Linux, the Aspire One's SD 
slot will only show up if a card was inserted when the machine was 
booted. That's how it's always been. I have code to fix it, which will 
land in the 2.6.29 timeframe with luck.

Thanks for the info. Just a couple questions:

- Is there any pointer to a patch that can be applied to current stable
 (2.6.27.6) ?
- I have tried to load acpiphp on the aspire and it says it has
  'No such device'. Does the patch include something to make it load and
  recognize the Aspire's PCI ? Is this module independent or do I need
  also pciephp or shpchp ?

TIA

http://lkml.org/lkml/diff/2008/11/13/420/1 ought to, with either luck or 
a little massaging.

That patch should be all you need.
