* RE: xilinx ml403 with 2.6 Kernel

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

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: 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.

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

Sounds like a reasonable trade-off.

* 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

* 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..

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.

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.

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?

Sent: Monday, June 19, 2006 5:24 PM

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?

* [PATCH 2/3] FS_ENET: use PAL for mii management
From: Vitaly Bordug @ 2006-06-20 14:58 UTC (permalink / raw)
To: Jeff Garzik; +Cc: netdev, linux-kernel, linuxppc-embedded
In-Reply-To: <20060620145825.24807.310.stgit@vitb.ru.mvista.com>
This patch should update the fs_enet infrastructure to utilize
Phy Abstraction Layer subsystem. Inside there are generic driver rehaul,
board-specific portion to respect driver changes (for 8272ads and 866ads).

* [PATCH 1/3] PAL: Support of the fixed PHY
From: Vitaly Bordug @ 2006-06-20 14:58 UTC (permalink / raw)
To: Jeff Garzik; +Cc: netdev, linux-kernel, linuxppc-embedded
This makes it possible for HW PHY-less boards to utilize PAL goodies.
Generic routines to connect to fixed PHY are provided, as well as ability
to specify software callback that fills up link, speed, etc. information
into PHY descriptor (the latter feature not tested so far).

* [PATCH 3/3] FS_ENET: phydev pointer may be dereferenced without NULL check
From: Vitaly Bordug @ 2006-06-20 14:58 UTC (permalink / raw)
To: Jeff Garzik; +Cc: netdev, linux-kernel, linuxppc-embedded
In-Reply-To: <20060620145825.24807.310.stgit@vitb.ru.mvista.com>
When interface is down, phy is "disconnected" from the bus and phydev is NULL.
But ethtool may try to get/set phy regs even at that time, which results in
NULL pointer dereference and OOPS hereby.

Whats interesting is that bad_page_fault should have walked the
exception tables and recovered, considering we have a __get_user call in
show_instructions.
While we should really understand why this failed, I suspect we should
be tighter with our checking. It looks like __kernel_text_address()
does what we want. Untested patch below.
Anton
Use __kernel_text_address when validating instruction addresses in the
Oops code.

Hello chen,
that's how we do it on our boards (a couple of 405GP(r) based adapters).
We normally hide the top meg's of RAM so that it is not used by Linux.
We setup the PLB side of the bridge to point to this RAM so that it is
accessable from the PCI side.

Thank you for the hint, i tested it and the results are deflating:
Most values are the same, but the communication bandwidths are worse
with the L3 cache enabled? Therefore i think that my L3CR settings are
wrong.

Hi there,
I remember similar problems. It all had to do with full or half duplex
ethernet.

Try adding the ",tcp" to the kernel's "nfsroot=..." parameter, i.e. use
commandline "root=/dev/nfs rw nfsroot=10.3.67.98:/opt/eldk_4_0/ppc_6xx,tcp
ip=10.3.67.99:10.3.67.98:10.3.67.1:::eth0:off panic=1".
I recall having similar problems when connecting through an 100/10Mbit switch
and in our case, the ",tcp" switch did the trick.
Cheers,
Kimmo Surakka

* RE: Exceptions during PCI initialization at u-boot

To: Liu Dave-r63238, linuxppc-embedded
Hi Dave,
Thanks for prompt response, it's really helped.=20
By reading ESR (error status register) I found that machine check
exception is coming because of "PCI parity error received on a write"
bit 7 of ESR is getting set.
Can you tell me reason and the possible solution for this one.

Hi Prabhat,
Be careful the register endian, these registers are little endian.
I suggest you do clearing the bit before pci_hose_scan.
I suspect the traps code have one bug inside of u-boot-1.0.0.

* RE: Exceptions during PCI initialization at u-boot
From: Prabhat_Singh @ 2006-06-20 9:58 UTC (permalink / raw)
To: Liu Dave-r63238, linuxppc-embedded
Hi Dave
Thanks for you comments.
I tried clearing 'PCI No response' as follows :
Unsigned int* EMR=3D( Unsigned
int*)0xf0010888;
Unsigned int* ESR=3D( Unsigned
int*)0xf0010884;
Before pci_hose_read_config_byte function I cleared the
the 'PCI No response' bit.
*EMR &=3D0xFFFFFFF7;
*ESR |=3D0x00000008;
Now it's getting reset and machine check exception coming all the time
continuously and board is not booting up.
I am clueless please advice what to do?
Regards
Prabhat

Subject: RE: Exceptions during PCI initialization at u-boot
Hi Prabhat,
Did you clear the 'PCI No response' in the error mask register
before you do PCI configuration read? If you didn't, machine check
will arise when PCI scan unpopulated PCI slot.
I notice that the MSR[12] is set, but the trap codes haven't
detect that, what is your toolchain?
Regards,

-----Original Message-----
Hi all
I am getting two exceptions, that you will find in log, at the
pci_hose_read_config_byte memory is crashing that's I found in
System.map. after second exception its boots properly. I have no clue
whats happening. And why I am not able to read Configuration space of
pci.=20
>From where this exception is coming?
Please help me out. What else I can check?

Could you also allow the regular "timebase-frequency" property
to consist of two cells, with the same semantics? That's what
some other systems do. Hey, it'd simplify this code, if anything :-)
In fact, some kernel code already does this if I'm not mistaken
(the Cell port, perhaps?)

I have a 2.6.17 kernel compiling and booting but still have little pb
with initrd attachement...
here is my .config file : you should modify it a little ml300 -> ml400
and modify your xparameters_ml400.h according to the hardware you
difined in xps or ise... You should also modify the kernel argument line
according to what you need root nfs or whatever you use...
