What is the problem? Why is this on wireless? It'd help if you'd make

Hi Petr,
you can clone the Xilinx Linux git tree at:
git://git.xilinx.com/linux-2.6-xlnx.git
The lin26-xlnx branch in the repository is based on 2.6.23 and contains support for the EMACLITE.
Hope this helps,

The patch is orthogonal to your issue.
There is NOT a driver in the kernel tree for the i2c on CPM2 based
parts like the 8248 (from what I can tell).

Since you're using 2.6.23, the IRQ for all devices is specified in the device
tree, not some header file. However, the device tree for the 8641 does not
specify any DMA nodes, so you need to add that. Here are the nodes for the 8610
that I'm going to add:
dma@21300 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "fsl,mpc8610-dma", "fsl,mpc8540-dma";
device-id = <0>;
reg = <21300 4>; /* DMA general status register */
ranges = <0 21100 200>;
dma-channel@0 {
compatible = "fsl,mpc8610-dma-channel",
"fsl,mpc8540-dma-channel";
device-id = <0>;
reg = <0 80>;
interrupt-parent = <&mpic>;
interrupts = <14 2>;
};
dma-channel@1 {
compatible = "fsl,mpc8610-dma-channel",
"fsl,mpc8540-dma-channel";
device-id = <1>;
reg = <80 80>;
interrupt-parent = <&mpic>;
interrupts = <15 2>;
};
dma-channel@2 {
compatible = "fsl,mpc8610-dma-channel",
"fsl,mpc8540-dma-channel";
device-id = <2>;
reg = <100 80>;
interrupt-parent = <&mpic>;
interrupts = <16 2>;
};
dma-channel@3 {
compatible = "fsl,mpc8610-dma-channel",
"fsl,mpc8540-dma-channel";
device-id = <3>;
reg = <180 80>;
interrupt-parent = <&mpic>;
interrupts = <17 2>;
};
};
dma@c300 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "fsl,mpc8610-dma", "fsl,mpc8540-dma";
device-id = <1>;
reg = <c300 4>; /* DMA general status register */
ranges = <0 c100 200>;
dma-channel@0 {
compatible = "fsl,mpc8610-dma-channel",
"fsl,mpc8540-dma-channel";
device-id = <0>;
reg = <0 80>;
interrupt-parent = <&mpic>;
interrupts = <3c 2>;
};
dma-channel@1 {
compatible = "fsl,mpc8610-dma-channel",
"fsl,mpc8540-dma-channel";
device-id = <1>;
reg = <80 80>;
interrupt-parent = <&mpic>;
interrupts = <3d 2>;
};
dma-channel@2 {
compatible = "fsl,mpc8610-dma-channel",
"fsl,mpc8540-dma-channel";
device-id = <2>;
reg = <100 80>;
interrupt-parent = <&mpic>;
interrupts = <3e 2>;
};
dma-channel@3 {
compatible = "fsl,mpc8610-dma-channel",
"fsl,mpc8540-dma-channel";
device-id = <3>;
reg = <180 80>;
interrupt-parent = <&mpic>;
interrupts = <3f 2>;
};
};
};
Please note that there is no support in the kernel for generic PowerPC DMA
transfers, so in addition to adding these nodes, you would also need to write
all the code to do the DMA transfers.

if you are using a bootloader see Documentation/nfsroot.txt in the linux
source tree (a quick example: nfsroot=192.168.0.1:/nfsroot,tcp,no_lock).
if you are using dhcp, then you have to tell your dhcp server to serv
these paramters (for the isc dhcpd: option root-path "/nfsroot,tcp,no_lock").

ERk.
So if I needed to read values from four i2c devices (raw access would be
fine) and I need to get this working in a few days, how would you suggest I
proceed? Kernel = 2.6.23+.
Do I need to start from scratch?
Start by using Jon's patch (or are the 5200 i2c and the cpm2 i2c
completely incompatible?)
What about other cpm2/i2c threads - Did they ever complete?

libhugetlbfs test suite and boot test on iSeries is sufficient in this
case. However, the version I sent would break on IA-64 due to the lack of
a definition for HPAGE_SHIFT when CONFIG_HUGETLB_PAGE is not set. Can you
confirm this patch still fixes the problem please? If it does, I'll send
it to Andrew as a fix for 2.6.24. Whether iSeries is legacy or not, this is
breakage and should be fixed.
Thanks
====
Ordinarily the size of a pageblock is determined at compile-time based on the
hugepage size. On PPC64, the hugepage size is determined at runtime based on
what is supported by the machine. With legacy machines such as iSeries that
do not support hugepages, HPAGE_SHIFT is 0. This results in pageblock_order
being set to -PAGE_SHIFT and a crash results shortly afterwards.
This patch adds a function to select a sensible value for pageblock order by
default when HUGETLB_PAGE_SIZE_VARIABLE is set. It checks that HPAGE_SHIFT
is a sensible value before using the hugepage size; if it is not MAX_ORDER-1
is used.
This is a fix for 2.6.24.
Credit goes to Stephen Rothwell for identifying the bug and testing on
iSeries. Additional credit goes to Andy Whitcroft for spotting a problem
with respects to IA-64 before releasing. Additional credit goes to David
Gibson for testing with the libhugetlbfs test suite.

I'm now running pauilis.git and 2.6.24rc2, along with a new custom
board. I still can't attach to the phy though. I know the phy works
because it works fine in u-boot. Clemens, IIRC you are using the
88e1111 - is that with the gianfar driver? I'm having problems getting
soft reboot to work with pauilis.git from some reason so debugging is
slow going - might someone have some hints?
Thanks,

* [PATCH] [POWERPC] vdso: Fixes for cache line sizes
From: Olof Johansson @ 2007-11-14 19:24 UTC (permalink / raw)
To: paulus; +Cc: dwmw2, linuxppc-dev
[POWERPC] vdso: Fixes for cache line sizes
Current VDSO implementation is hardcoded to 128 byte cachelines, which
only works on IBM's 64-bit processors.
Convert it to get the line sizes out of vdso_data instead, similar to
how the ppc64 in-kernel cache flush does it.

Paul, this is needed to make for example the IBM jvm run on pa6t. Please
include as bugfix for 2.6.24.

Sorry about the confusion I thought the mpc82xx chips had the same i2c
core as the mpc52xx but I was not correct.

I was busy all day long with some other broken hardware stuff.
As I told you yesterday, I was able to boot the mpc8540ads_defconfig
paulus.git tree. I was just able to boot it to see boot messages, where
I stopped yesterday ('cause time squeezes all men under it's foot like a bug).
Today I finished my kernel config and booted up my distro but...
klump... network doesn't work either. Maybe I only got some PHY
addresses wrong (I don't remember).
The 88e1111 works fine, in u-boot, too.
So, we might sit in the same boat again...
I am about to start more debugging...
My current Kernel config is attached.
Any hints are welcome - of course.
Regards,
Clemens Koller

I can also ACK your reboot-problem.
$ shutdown -r now
stops here at:
Restarting system.
IIRC, there were some patches some time ago changing some powerpc
reboot stuff...
Propably, git-bisect will be our friend.
The latest working kernel over here was:
Linux-2.6.21-rc5-g9a5ee4cc with ARCH=ppc
I think it was also from paulus.
Now I am at ARCH=powerpc.

Please call the fields "block size" not "line size". There are subtle
differences and per architecture, it should really be block size.

You have to ask the right person. :-) I've been defacto mainaining
the rpaphp code for unpteen years now. On the other hand, I am also
much, much better at promising than delivering.

I chopped out several hundred LOC from rpaphp a year ago,
and hopefuly that might make furthre simplification easier
someday.

This patch implements exactly what you describe. Boot tested.
I assume you really mean it -- if so, then please review and
ack the patch !?
I have absolutely no clue if this breaks any existing IBM tools.
I'm pretty sure it doesn't ... but attention Mike Strosaker! does it?

I've been asked to post the script again, might as well update with the

See below. I normally use this as:
$ CROSS_COMPILE= ARCH=powerpc TARGET="vmlinux modules" buildall
modules won't build on some of the embedded platforms though, so you'll
have to weed out those build errors by hand, or do:
$ CROSS_COMPILE= ARCH=powerpc TARGET=vmlinux buildall

#export CC="ccache gcc"

* [PATCH v2] [POWERPC] vdso: Fixes for cache block sizes
From: Olof Johansson @ 2007-11-14 21:28 UTC (permalink / raw)

In-Reply-To: <1195072102.28865.41.camel@pasglop>
[POWERPC] vdso: Fixes for cache line sizes
Current VDSO implementation is hardcoded to 128 byte cache blocks,
which are only used on IBM's 64-bit processors.
Convert it to get the blocks sizes out of vdso_data instead, similar
to how the ppc64 in-kernel cache flush does it.

Alright. I've added block sizes since I'm not sure whether the old
systemcfg data is actually line or block sizes, and I guess it's something
we need to stay compatible with. See separate new patch.
Also, ppc64_caches only has line sizes, so fill it with that for now. I'll
submit a separate patch to complete ppc64_caches with block sizes,
but that's a cleanup not a bug fix (i.e. target for that would be 2.6.25).

Me neither, and the fact that the vdso was hardcoded for 128 had
completely passed me by.

Hi, Robert!
Just one more short note...
My good - vs. - bad dmesg output:
good 2.6.21-rc5-git:
> Gianfar MII Bus: probed
> eth0: Gianfar Ethernet Controller Version 1.2, 00:ww:xx:yy:zz:dd
> eth0: Running with NAPI enabled
> eth0: 256/256 RX/TX BD ring size
> eth1: Gianfar Ethernet Controller Version 1.2, 00:ww:xx:yy:zz:dd
> eth1: Running with NAPI enabled
> eth1: 256/256 RX/TX BD ring size
> eth2: Gianfar Ethernet Controller Version 1.2, 00:ww:xx:yy:zz:dd
> eth2: Running with NAPI enabled
> eth2: 256/256 RX/TX BD ring size
> Marvell 88E1101: Registered new driver
> Marvell 88E1111: Registered new driver
> Marvell 88E1145: Registered new driver
(I've wiped out my MAC)
bad 2.6.24-rc2-git:
< Gianfar MII Bus: probed
< eth0: Gianfar Ethernet Controller Version 1.2, 00:00:00:00:00:00
< eth0: Running with NAPI enabled
< eth0: 256/256 RX/TX BD ring size
< eth1: Gianfar Ethernet Controller Version 1.2, 00:00:00:00:00:00
< eth1: Running with NAPI enabled
< eth1: 256/256 RX/TX BD ring size
< eth2: Gianfar Ethernet Controller Version 1.2, 00:00:00:00:00:00
< eth2: Running with NAPI enabled
< eth2: 256/256 RX/TX BD ring size
The MACs are all 00 here.
The PHY drivers don't get registered.
(What happened to CONFIG_NETDEV_1000 in the newer kernels?)
How is your mileage?
Next round... tomorrow,
regards,
Clemens Koller
