In my ignorance, I set KVM=m on a non-44x build, which then failed. This
needs either to depend on 44x, or to be fixed to compile.

The link doesn't seem to be related.
I'll rework the patch to move CPM2 GPIO support to cpm_common.c. Have you
thought about a proper name for the compatible property ?

(blind shot) Maybe this means that some code that is in i2c-core should
be moved to i2c-boardinfo instead? i2c-boardinfo is always built into
the kernel even when i2c-core is modular.

Hi Laurent,

I guess most of this should go to cpm_common.c and should be used for
Port E on CPM1, as well. This port uses the same layout as CPM2 while
Port B uses a different layout. See the discussion in
http://patchwork.ozlabs.org/linuxppc/patch?id=16282

* Xilinx network trouble
From: Guillaume Dargaud @ 2008-04-17 10:04 UTC (permalink / raw)
To: linuxppc-dev
Our network guru is out on vacation, so I'll ask here...
I now have a working Xilinx ML405 board... except the network is flaky to
say the least.
I have tried both with the Emac Lite and the LLTemac IPs.
They both work during the DHCP state of the kernel boot, my target board
gets its IP and network parameters alright from the host DHCP server.
The Emac Lite can ping both ways, but with 500ms and 30% packet loss when
pinging from the host PC and 300ms and 70% packet loss the other way. And it
goes in hiccups: 30s or so with no pings, and then 30s or so with 90%
success... RX/TX LEDs also are dark when there's nothing going on.
When using the LLTemac, ping just doesn't work.
ifconfig shows no drops and no collisions in both cases.
I'm no network specialist so I don't know what kind of tools I can use for
further diagnosis.
Here are some of the relevant kernel options I've set for both
configurations:

This patch implement GPIO LIB support for the CPM2 GPIOs.
The code is based on Jochen Friedrich's patch for the CPM1.

It looks like it. i2c-core needs to be compiled static for the OF bindings to work.
I guess in Kconfig "depends on OF && I2C" must be changed into "depends on OF && (I2C=y)"
On the other hand, i didn't test the patch without the dependent patches, so it might not work as expected:
http://patchwork.ozlabs.org/linuxppc/patch?id=17833
http://patchwork.ozlabs.org/linuxppc/patch?id=17834

Hello,
My apologies for that. The patches that are now in x86#testing were
needed because of changes I introduced. Thomas Gleixner found a
problem with the patches that caused compile problems for basically
all archs with GENERIC_FIND_NEXT_BIT=y, and his fix was to change
asm-generic/bitops/find.h. However, ppc and powerpc did things
differently... (x86 too, but they have special permissions ;) )
(Better late than never) Please consider applying the patch in
http://lkml.org/lkml/2008/4/16/107
as:
[PATCH] powerpc: use asm-generic/bitops/find.h in bitops.h
Powerpc (and ppc) have some code in their bitops.h that is
exacly the same as asm-generic/bitops/find.h. Include this
header instead of the private implementation.
> How come patches to unify x86_32 and x86_64 bitops need to end up
> touching powerpc?
This was not a pure unification. Originally I wanted to convert
both x86_64 and i386 to the existing generic bitops. Andi Kleen,
however, objected because x86_64 would than lose a certain
optimization for small bitmaps. I moved this optimization to
the generic code, and broke non-x86. Everyone except ppc/powerpc
was fixed by Thomas Gleixner (in a generic header file).
http://lkml.org/lkml/2008/4/16/107 just changes ppc/powerpc in
such a way that Thomas' fix works there too.

Alexander

If you look into the function carefully enough, you can find that =
old_serial_port is optional and can be empty. It seems to be some =
leftover to provide backward compatibility when the port structure =
changed.

Hi
I Have the kernel patches , but no one for the USB.
The changes for the USB are integrated in the Kernel.
I am currently looking into the linux BSP for usb
changes , but unfortunately don't find any major
chages.
MPC8641 board have one EHCI controller and 3 OHCI
conroller.
As I am also new to USB , it would be great help, if
someone give me any idea about the changes in new
MPC8641 BSP ?
Does freescale fix the PCI Express issue , that makes
USB works.
I have lots of hope with this forum :-)
With Regards
John

* Mount linux file system from sd card on ml403 board
From: Antoine BRUNET @ 2008-04-17 7:17 UTC (permalink / raw)
To: linuxppc-embedded
[-- Attachment #1.1: Type: text/plain, Size: 922 bytes --]
Hi,
I have a ml403 board. I have connected a SD Card on the GPIOs of one opb_spi IP.
My linux kernel is a secret lab kernel. This kernel start is ok on ml403 with a filesystem on NFS server but I have to boot this kernel with a filesystem on SD CARD.
First question :
What is the command line to boot directly on SD CARD filesystem?
Second question :
There is drivers for sd card on linux kernel. Can I use one driver for my specific application or I have to write a new driver for support sd card from opb_spi IP?
Xilinx says that the opb_spi IP is based on M68HC11. I can't find any driver for M68HC11 on linux.
Thanks

* A question about the 8250/16550 Driver

To: Linu PPC Mail list; +Cc: scottwood
[-- Attachment #1: Type: text/plain, Size: 945 bytes --]
Hello:
I have founded that the serial can't be initialized as the bootting process. My platform is MPC8313 and my kernel version is linux-2.6.23.9. I look though the source code and find that the MPC8313 driver is compatible with 8250/16550. The driver is in the \drivers\serial\8250.c
In the function serial8250_isa_init_ports we should use the structer old_serial_port but i can't find the definition for this struct. I can only find the following senrense in the head of this file
#ifndef SERIAL_PORT_DFNS
#define SERIAL_PORT_DFNS
#endif
static const struct old_serial_port old_serial_port[] = {
SERIAL_PORT_DFNS /* defined in asm/serial.h */
};
i think this is a bug for this driver. Could any one can told me how to define the SERIAL_PORT_DFNS for the MPC8313 system? Hi Scott, Have you ever find this problem and how do you solve it.
Thanks

There shouldn't be any, but if you have a BSP from Freescale you
should have patches to that kernel as well.
We should be using the stock USB driver for the ULI chipset. (I
forget if its ehci/ohci/uchi).

I didn't see this the first time (didn't get cc'd).
It looks mostly okay, but in doesn't have any mutual exclusion which
it probably should have. What are the users of this?
Cheers,

As we didn't get negative feedback yet, could this go into the 2.6.26
merge window?

* [PATCH 3/3] [POWERPC] irqtrace support to 64-bit powerpc
From: Benjamin Herrenschmidt @ 2008-04-17 4:35 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
This adds the low level irq tracing hooks to the powerpc architecture
needed to enable full lockdep functionality
Partly based on Johannes Berg's initial version, removing the asm
trampoline that isn't needed (thus improving perfs) and all sorts
of bits and pieces, reworking most of the assembly, etc...

* [PATCH 2/3] [POWERPC] lockdep stacktrace support
From: Benjamin Herrenschmidt @ 2008-04-17 4:35 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
From: Christoph Hellwig <hch@lst.de>
I recently tried to work on lockdep for powerpc. I have preliminary
version of the stacktrace code, but had to give up on trace irqflags
support because I'm not that knowledgeable on lowlevel ppc details.
Maybe someone more faimilar with the code wants to give it another try?
My stacktrace code is below:

* [PATCH 1/3] [POWERPC] Move stackframe definitions to common header
From: Benjamin Herrenschmidt @ 2008-04-17 4:34 UTC (permalink / raw)
To: Paul Mackerras; +Cc: linuxppc-dev
This patch moves various definitions used all over the place
to parse stack frames to ptrace.h so only one definition is
needed.
