Does it really make sense to do this under a config option? I don't see
why anyone would not want to know that their machine is about to melt.

Tim,
There's also a Linux 2.4 patch provided with the ML403 PPC reference
design on the Xilinx website
(http://www.xilinx.com/products/boards/ml403/reference_designs.htm) that
takes care of a Virtex-4 PPC cache issue (CCR0 register). Have you
applied this?

Subject: Linux on Virtex4
I have been working with a small module made by Memec/Avnet
(FX12MM1-BASE) that has a Virtex-4 FX12 with some DDR SDRAM, a Gigabit
Ethernet PHY, some FLASH, etc. I am using EDK 8.1 and generated the BSP
for MontaVista 3.1 "preview kit" (which is based on the 2.4.20 kernel).
This works, but occasionally panics while booting (doesn't panic all the
time, maybe 1/3 the time). Examples of "good" boot and 2 "crash" boots
below. We are using a root filesystem over NFS, and the panics seem to
always be after the file system is mounted. I'm not sure if it is NFS
related or not.
I have also been working with the paulus 2.6 kernel tree (and I have
tried the MVL linux-xilinx-26 tree), but have not been able to get the
kernel to boot. The primary problem there is that we are using the
uartlite instead of the full uart, and the patches I have found for
uartlite support don't work. I can get the early serial messages to
work, but I don't know enough about the console and serial core to get
everything else working. I am also getting panics that seem to be
non-serial related, but I haven't tracked it down yet.
So two questions:
1) Is there anything obvious from the kernel panics below that I should
be looking for? Just the answer "linux 2.4.20 is really fricken old,
upgrade" is probably the right answer.
2) Does anyone have working UartLite support on a Virtex-4 FX12 design?

You can only have that when running on bare metal. Machines that run
on a hypervisor can't run that code.
It probably makes sense to auto-select that option for CONFIG_CELL_BLADE
though.

Basically, I just brought what was already in ppc over to powerpc.
I didn't really think about it much.

Yeah, that's a better way to do it.
I'll make a new patch.

* help reg: transfer of files to target kernel from host(PC)
From: Viswanatha Reddy @ 2006-06-20 15:22 UTC (permalink / raw)
To: linuxppc-dev
Hi,
We are working on powerPc 405EP taihu board.
Our work is to run the C code and debug the code on taihu board.
for that we istalled ELDK ppc_4xx tools on host system(Which has Fedora
core as OS). We are able to complile C file without board, generated
target file.
We configured NFS server successfully and able to transfer files to target
after U-boot.
Once we entered into the Linux of the kit, We are unable to load the files
from NFS server, we are failed to mount the ELDK tools on Target machine.
When we tried to Ping the server from the target it is pinging.
From the host(PC) we are communicating the target using Telnet.
To mount the files we are using the command:
mount -t nfs 192.168.1.18:/opt/eldk/ppc_4xx /mnt
We are getting the error saying
mount: mounting 192.168.1.18:/opt/eldk/ppc_4xx on /mnt failed no such file
or directory.
please help us regarding this..
Best Regards,
Viswanath..

* OF setprop question
From: Mark A. Greer @ 2006-06-20 17:40 UTC (permalink / raw)
To: linuxppc-dev
What does OF do when you 'setprop' a property that doesn't already exist?
Does OF create it?
What if it exists but the new prop requires more space than the old prop?
Does it make space more space for the new property?
Thanks,
Mark

Well, it's harmless to build it in even on hypervisor systems, right?

Sounds like a reasonable trade-off.

* RE: regarding xilinx system ace in linux-2.6
From: John Bonesio @ 2006-06-20 17:30 UTC (permalink / raw)
To: Jeff Angielski, rahul; +Cc: linuxppc-embedded
Hi,
Xilinx has contracted MontaVista to create an LSP for the ML40x
development boards for MVL Pro 4.0 (which uses the 2.6.10 kernel). This
work is nearing completion. We (Xilinx) have also asked MontaVista to
make those drivers available via open source, and MontaVista has agreed
to this.
The LSP is anticipated to be available sometime before the end of this
month. I'm not sure when the drivers will be made available to open
source.
Hope this helps,
- John

Last I heard was that Xilinx was working on the linux 2.6
implementation. =20
You should contact your Xilinx representative to find out the current
status of that effort and/or where you can get the source code.

Yes sorry about that ...
server crash ... hard ... we kinda lost a lot. Hopefully =20
gitbits.246tNt.com which host the bestcomm stuff is on another server.
I also have a newer / cleaner version of the patch. I've sent it to some
dev (Dale, Andrey & John) for comments (any news on that guys ? or are you
just fine with it ?)
But anyway, it's mainly internal cleanup and adapting drivers
from the public version on my git tree to this newest/cleaner
version is a 15 min work ;)

* RE: xilinx ml403 with 2.6 Kernel
From: John Bonesio @ 2006-06-20 18:42 UTC (permalink / raw)
To: "Karl Prüfer", linuxppc-embedded
Hi,
Support for linux 2.6 from the EDK tools does not yet work. Xilinx has =
contracted MontaVista to create an LSP for the ML40x development boards =
for MVL Pro 4.0 (which uses the 2.6.10 kernel). The LSP is anticipated =
to be available sometime before the end of this month.
The use of xparameters_ml403.h does not provide the complete solution =
for building linux 2.6 on the ml403 board.

Subject: Re: xilinx ml403 with 2.6 Kernel
Hello again!
I had a little mistake in my first mail.
I have copied the whole BSP...
Now i have tried to copy only the xparameters_ml403.h in =
arch/ppc/platforms/4xx/xparameters/ but get the same error!!
I would be more then happy when somebody could help me.
nice greetings Robert

Cool ;) But it's far from being my whole work. The foundation and a good
cleanup pass comes from Dale and Andrey respectiverly.
Be sure to use the latest one I sent you though ;p
BTW, I guess that means your fine with my last modifications ?

Which version of the Linux kernel is this? Make sure to use top of
tree in the git repository.
Alternatively, use ELDK 3.1 1 which is better suited for a 2.4 kernel
tree.

This should not be necessary. If it does help, this means you are
just covering a bug.

If its always built in, then I guess we don't need the conditionals
in cell/setup.c:
+#ifdef CONFIG_CBE_RAS
+ cbe_ras_init();

How's this?

MPC10x-style interrupt controllers have a serial mode that allows
several interrupts to be clocked in through one INT signal.
This patch adds the software support for that mode.

Now that was easy :-)
Just out of interest, what in the wording of the OF spec didn't
make this clear to you? Would be great to improve it ;-)

Sure, that's why we should remove every symbolic constant in every
driver anywhere in the kernel right ? Sure would help.

Well, it's not quite clear yet wether that thing works at all at this
point :) It shuld be a config option (becasue those things don't make
sense on LPAR cells) but maybe not a selectable one ...

* [PATCH] powerpc: disable OProfile for iSeries (take 2!)
From: Kelly Daly @ 2006-06-21 1:51 UTC (permalink / raw)
To: paulus, linuxppc64-dev; +Cc: anton
This patch removes the changes from an earlier patch that disables oProfile for iSeries within the oProfile KConfig (submitted Feb 23, 2006). Checks within the arch init for iSeries, still allowing profiling for timer interrupts.

Hi Xavier,
Just wrapped up efforts to experiment with hard TEMAC support in 2.4 kernel
( previev kit from Montavista ). DENX 2.4 distro should not be different.
Here are my experience with ML403 board:
Configure kernel for only eth driver offered for ML300 / ML403 ( soft EMAC -
10/100Mb on-chip eth ). After updating kernel tree with the BSP using xilinx
patch script for ML403, hard TEMAC driver will end up in
/drivers/net/xilinx_gige ( supported soft MAC driver ends up in
/drivers/net/xilinx_enet ).
>From here 2 options:
a) rename xilinx_gige folder to xilinx_enet and build kernel
b) modify config.in script for kernel network configuration and makefile for
building net driver by addidng new GIGE option
>From my undersanding part of driver code for gige ( adapter.c ) is PHY
specific and supports Marvel's PHY on ML403 board. Never looked more what it
does ( phy interface should be common to all PHYs ? ) but if you use
different PHY maybe you'll have to do some coding here ?!
( look for the comments in the driver )
Oh yes, my tree was missing gmii.h file ( found it throuh google - don't
remember from where - first google hit :) !
Did some test measurement and comparison with soft EMAC against hard TEMAC
+ PLB TEMAC and defualt SG DMA mode (3):
Amazing performance increase: close to 100% on tcp ( netperf and netio shows
over 11000KB/s for max packet size of 32K on 100Mb link )
Hope this helps !
Goran,
Waterloo,Canada

AFAICT that still doesn't let us build a combined kernel, but I haven't
looked at the code.
