Normally we do. But we appreciate the reminder. Particularly since it
reminded me that I need to chase Jeff down about the ibm_newemac patches
that were sent a while ago.

* [PATCH 0/3] Support for Wind River SBC8641D board
From: Paul Gortmaker @ 2008-04-10 23:22 UTC (permalink / raw)
To: linuxppc-dev
The following patches add support for the Wind River SBC8641D board.
I've done it by starting with the current mpc8641_hpcn support and
then making the changes from there, so it should be 1:1 comparable
with the HPCN platform, which aids in tracking/applying future changes.
The SBC8641D support essentially boils down to trimming back stuff
from the HPCN platform, as this board doesn't have the Uli and all
the devices/busses etc. that the HPCN cascades from that. Plus of
course, the dts changes for the localbus specifics.
Patches that aren't included here, but submitted separately are the
support for the Broadcom 5464 quad PHY and the ability to have the
Gianfar TBIPA be auto assigned (since this board puts a PHY at 0x1f).
I expect the defconfig will probably be in an 86xx subdir, based on
what Kumar sent today, but for now it is still in configs. I'm hoping
to see this queued up for 26, if all goes well.
Thanks,
Paul.

* [PATCH 1/3] powerpc: Add support for Wind River SBC8641D board
From: Paul Gortmaker @ 2008-04-10 23:22 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Gortmaker
In-Reply-To: <1207869739-19892-1-git-send-email-paul.gortmaker@windriver.com>
This adds support for the Wind River SBC8641D board, based
largely on the mpc86xx_hpcn support. The biggest difference is
the lack of the Uli and the i8259 cascade, which simplifies things.

* [PATCH 2/3] powerpc: Add device tree source for Wind River SBC8641D
From: Paul Gortmaker @ 2008-04-10 23:22 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Paul Gortmaker
In-Reply-To: <0006b107cbf99a968352d9369a8e26304d4bf13a.1207868891.git.paul.gortmaker@windriver.com>
This adds in the device tree source for the SBC8641D, based
largely on the mpc8641_hpcn.dts. The biggest differences are
the lack of a complex IRQ mapping (since no Uli/i8259 cascade)
and the different layout of devices on the localbus node.

* [PATCH 2/5] gianfar: assign mii_bus value in dev->priv

The gianfar priv struct has an entry for the mii_bus, but it
isn't being populated. Assign a value for it at the same time
as we assign the phydev, so that it can be used in calls like
gianfar_mdio_read/write.

* [PATCH 1/5] phylib: don't create a phydev for ID-less PHYs.

I've tested on 8360, 8540 and 8641D and in all cases, the PHY
ID returned for bus addr 0x1f is all zeros, and not all 0xf.
This means we've been allocating a phydev for this "ghost".
In addition to marking 0x0 as an invalid PHY ID, I've also
changed the existing somewhat useless printk to actually
list the bus IDs where it found a PHY so we get a basic
bus summary.

* [PATCH 4/5] gianfar: dont hog the mii_bus->priv with just the regs.

The gfar was previously using the mii_bus->priv to directly
store the gfar_mii regs, which leaves no room/flexibility to
store anything else there. I believe it makes more sense to
have mii_bus->priv point at a struct gianfar_mdio_data and
then have the regs stored as a field within that. It makes
the code easier to read too.
This isn't in a hot path, so there should be no performance
penalty associated with this.

The gfar_local_mdio_read/write functions were brought in via
extern since they go right at the regs vs. going via the normal
gfar_mdio_read/write functions. With the priv->mii_bus properly
set, we can get rid of the externs, the casts etc. and use the
normal gfar_mdio_read/write. We just need to move the call to the
gfar_configure_serdes down slightly to after where priv->mii_bus
is set to a sane value.

* [PATCH 5/5] gianfar: don't hard code the TBIPA MDIO address

Currently the MDIO address for the gianfar Ten Bit
Interface is hard coded to be 0x1f, which can conflit
with some boards if they happen to put a PHY there.
Previous discussions indicated that the proper approach
here would be to dynamically allocate it, based on
picking the highest MDIO address that is not in use
by a PHY.

I may be missing something, but I don't think this quite right.
If you have a PHY at 0x1f, this patchset will cause no PHY device to
be allocated for that address, and you'll actually end up assigning
TBIPA to be 0x1f again, since there's no PHY there. Right? Were you
able to use this code with a PHY at 0x1f?
I like the idea of passing around priv->mii_bus instead of regs, but I
think it won't work without becoming unnecessarily unwieldy. The
problem is that the TBI PHY is not necessarily accessed through the
same bus as the PHY. Each controller has its own TBI PHY, and that
PHY can only be accessed from *that* controller's MDIO bus. So if you
want to configure TSEC2's TBI PHY, you use TSEC2's MDIO regs. That's
what gfar_local_mdio_* allowed; they write the *local* controller's
MDIO regs. It looks like this code sets up priv->mii_bus to point at
the bus which holds the PHY, but only TSEC0's bus (on most SoCs) is
connected to actual PHYs. So you will only ever be able to configure
the TBI PHY on TSEC0, which will not allow any of the other TSECs to
use an SGMII PHY. Were you able to use other TSECs to connect to an
SGMII PHY?
We could still pass around an mii_bus reference, but this would
require creating an mii_bus instance for every single TSEC, which is a
little heavyweight when we just want to configure the TBI PHY once on
startup.
After some thinking, I went ahead and implemented a patch which isn't
ideal, but should solve the problems your patches set out to solve.
I've sent it in a separate message. If you have some systems with
SGMII and/or a PHY at 0x1f, please test this patch on them. I don't
currently have either.

* [PATCH v2.6.26] gianfar: Determine TBIPA value dynamically
From: Andy Fleming @ 2008-04-10 23:34 UTC (permalink / raw)
To: netdev; +Cc: paul.gortmaker, linuxppc-dev
TBIPA needs to be set to a value (on connected MDIO buses) that doesn't
conflict with PHYs on the bus. By hardcoding it to 0x1f, we were preventing
boards with PHYs at 0x1f from working properly. Instead, scan the bus when
it comes up, and find an address that doesn't have a PHY on it. The TBI PHY
configuration code then trusts that the value in TBIPA is either safe, or
doesn't matter (ie - it's not an active bus with other PHYs).

I think this should go in, but I'd like to see some testing first. I don't
have hardware which is affected by this. I've only confirmed that it doesn't

* [PATCH 1/2] Add thread_info_cache_init() to all archs
From: Benjamin Herrenschmidt @ 2008-04-10 23:36 UTC (permalink / raw)
To: linux-kernel; +Cc: Linux-Arch, linuxppc-dev, takata, linux-m32r, Paul Mackerras
Some architecture need to maintain a kmem cache for thread info
structures. (next patch adds that to powerpc to fix an alignment
problem).
There is no good arch callback to use to initialize that cache
that I can find, so this adds a new one and adds an empty macro
for when it's not implemented.
Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
---
So we have the choice here between:
- the ifdef on the func name that I did, consistent with what
I did before for iomap, which iirc Linus liked
- add some more ARCH_HAS_* or HAVE_* (yuck)
- add an empty definition to all archs .h (pain in the neck but I
can do it, though it will be an annoying patch to keep around)
- do a weak function (will slightly bloat everybody for no good reason)
So unless there is strong complaints, I'd like to stick to my
current approach.
(This one fixes a stupid typo, missing () in the macro def.)

* [PATCH 2/2] [POWERPC] Fix kernel stack allocation alignment
From: Benjamin Herrenschmidt @ 2008-04-10 23:36 UTC (permalink / raw)
To: linux-kernel; +Cc: Linux-Arch, linuxppc-dev, takata, linux-m32r, Paul Mackerras
The powerpc kernel stacks need to be naturally aligned, as they
contain the thread info at the bottom, which is obtained by
clearing the low bits of the stack pointer.
However, when using 64K pages (the stack is smaller than a page),
we use kmalloc to allocate it, which doesn't provide that guarantee.
It appeared to work so far... until one enables SLUB debugging
which then returns unaligned pointers. Ooops...
This patch fixes it by using a slab cache with enforced alignment
for those. It replies on my previous patch that adds a
thread_info_cache_init() callback.

* [PATCH 0/5] dynamic detection of gianfar TPIPA
From: Paul Gortmaker @ 2008-04-10 17:51 UTC (permalink / raw)
To: linuxppc-dev; +Cc: scottwood, linux-net
This patch series consists of some minor cleanups that eventually
allow us to implement a dynamic assignment of the gianfar TBIPA.
This was the implementation that Andy and Scott indicated was
the most desireable solution at the bottom of this discussion:
http://patchwork.ozlabs.org/linuxppc-embedded/patch?id=12902
The lead up patches are as follows:
-dont allocate a phydev for the "ghost" phy that seems to appear
on ID 0x1f of all the MDIO bus scans.
-add in the missing assignment to priv->mii_bus when we assign a
phy to the device.
-cleanup of unnecessary externs that the above change allows us.
-make the mii_bus->priv point to struct gianfar_mdio_data
At this point, we can then actually use the phy_map of the mii_bus
to tell us which MDIO ID we can use for the TBIPA, instead of just
hard coding 0x1f.
Paul.

You need an of_node_put(np) in here somewhere (probably after the mpic_alloc).

No, it doesn't need to change, the current patch is entirely correct,
just a little bit more complicated than it needs to be, and I try
not to have code in anticipation of something getting more complicated
in the future, you can always add the complexity at the point where you

Why not? Unlike the platform_initcall, it wouldn't cost anything and your
current code has the same effect in the end, but in a less obvious way.

This is likely something that has evolved from the original patch which
added a machine_late_initcall(<machine>, ppc44x_idle_init) to every
platform.c file. It made the original patch overly complicated as
opposed to adding a single arch_initcall in a common file. That was
also before we decided to make "wait" the default, which made things
much easier to deal with.
I'll take the blame for the way the minorly suboptimal state the patch
is, as Jerone had to jump through several hoops already at my request.
I agree it's cleaner to do as you suggest in the long run, and may well
make some changes along those lines myself.

Mine did lots of stuff fine.

I had only tested with Linus's tree plus the small handful of post-2.6.25
cleanup patches I've posted in the last few weeks. To be precise it was
9597362d354f8655ece324b01d0c640a0e99c077 plus several of my cleanup patches
(that are probably all in -mm, but I'm not sure off hand).
I'd rebased my tree today to 783e391b7b5b273cd20856d8f6f4878da8ec31b3
anyway. I just tried the new kernel with the sigmask cleanups and only
a few other patches, and have no problems.
The details of your crash make it look pretty unrelated to this code.
Off hand I would guess that it's some other bug from other -mm patches
that just happens only to bite you on powerpc. If the crash is not
intermittent and you bisected it to this one change, then I am at a
loss to see what might be happening. I'd have to leave it to Paul et
al to figure out if there is some strange powerpc juju going on.
Thanks,
Roland

Hi Paul,
A couple issues. (These should be fixed in the mpc86xx_hpcn.c as well.)

Make this function static.

This one too.

"mpc86xx" is too generic. You should make the compatible field
in your devtree something like "WIND,sbc8641d", to differentiate
it from the mpc86xx_hpcn.

Another static function.

It's 100% repeatable and I bisected it to this change.
I expect you could repeat it by applying it to
http://userweb.kernel.org/~akpm/mmotm/ (or to -rc6-mm2, if I ever manage to
get it to boot on something) and using
http://userweb.kernel.org/~akpm/config-g5.txt
