SATA port multiplier(Marvell 6121 with ahci) and Marvell 4140, simg 3726

[KueiHuan Chen]

Hello,

  This is the resent mail, because original one was deny by vger.kernel.org.

  We got some problem while evaluation port multipiler with libata, we
had tested with two sata chip, one is sil-3132, the another is Marvell
6121. And we also have two port multiplie: Marvell 4140 and Sil-3726.
Our kernel version is kernel-2.6.24 with Marvell 5281 platform.

  Testing result:

  Sil 3132 with 3726 and 4140: everything looks like fine.

  Marvell 6121 with 3726 and 4140(using ahci.c): both port multipiler
would got problem. It can't be detected whether hotplug or at boot
time. But the disk detection is fine without port multiplier.
  Because we can't upgrade kernel to latest version so quickly, is
there any hint or solution for us ?

Thanks a lot.

Here is the boot message:

mv PMP support was added very recently.  2.6.26 has it.

Heh.. didn't read the last line.  If you can't upgrade the kernel,
you'll need to backport.  We had to fix core PMP support quite a bit to
get mv working, so you'll need to backport whole libata, which usually
isn't too difficult.  Someone knowledgeable would be able to pull it in
a few days but if you don't know what you're doing it can be pretty
hairy.  :-)

  Thanks your reply Tejun, i would try it  ^__^.

  Before that, Could i ask a question that had you ever try to using
port multiplier(sil 3726 or marvel 4140) with 6121/6145
succefully(with ahci.c) ?

Thanks.

Eh.. another mistake by me.  I was talking about controllers supported
by sata_mv.  Mark Lord worked on it and added PMP support.  AFAIK PMP
support on 6145/6121 is yet to arrive.  Right, Mark?

Thanks.

I have exactly zero documentation on those chips,
but they are supposedly AHCI compliant.

Looking in drivers/ata/ahci.c, one can see that the chips are indeed supported,
and there the AHCI_HFLAG_NO_PMP is *not* set, so one might expect them to work
with a port-multiplier already.  ?

 Thanks for your explaining, i had tried it already.

 Port multiplier of Silicon image 3726 is not supported from 2.6.24 to
2.6.26 with 6121 and 6145 which using ahci.c  : (

 Here is the test envirement:

  Port Multipiler : Silicon image 3726. (Marvell 4140 is not fully
tested, so i don't listed, but it is the same in arm arch.)

 arch/kernel   2.6.24        2.6.25       2.6.26

  arm            Not Work   Not tested   Not tested

  powerpc     Not Work   Not tested   Not tested

  x86_64       Not Work   Not Work     Not Work


 Should we need disable 6121/6145 pmp support in ahci.c until it is
fully supported?

Thanks a lot.
--------------------

  Temporal disable pmp support in 6121/6145 until it is fully supported.

I'd like to find out why it's failing before disabling it.  Can you
please post the failing log from 2.6.26?

Backport libata from 2.6.26 to 2.6.24 is trivial compared
to other stuff I've seen backported. Below is an initial version
someone else did for 2.6.26-rc5 and it seems to be working.
It at least will give you an idea of what changed.

Steps to apply are:
o rm -rf 2.6.24/drivers/ata
o copy 2.6.26/drivers/ata to your 2.6.24/drivers/ata
o apply the following patch and it should at least compile.

hth,

Hi,

  Sorry for delay responding, here is my x86_64 with 2.6.26 dmesg and
lspci.  ^__^

Thanks.

Dmesg: hotplug-in 3726 into 6145 , and the unplug, finally plug again

Heh.. failing PMP READs.  Doesn't look like there's anything else to do
than disabling it.  Will post a patch.

..

No kernel timestamps there, but I do wonder if somehow
the driver is polling too soon for the PMP?
I wonder if a short delay in there, before issuing the PMP read,
might help (or not)?
