Hi Sudheer,
    Sorry, I ate my words there. I meant - I shall soon be posting a
patch that contains my port of the SystemAce driver for 2.6 kernel.

Re: Xilinx SystemACE driver for 2.6

[Ming Liu]

Hi friend,
I have tried your patch for SystemACE. Unfortunately, it looks that I got 
some problem. I applied the patch and compile the kernel. There are some 
XPAR_... parameters defination missing. So I include the xpamameters header 
file( I use the xparameters_ml300 which was generated by EDK and rename it 
as xparameters_ml403.). Then I compiled out the kernel and change it into 
.ace file. When I want to boot the kernel from SystemACE, there is no 
information to say that the linux is booting. So I think the problem is 
still on the driver of SystemACE. My linux version is 2.6.16-rc5. And I 
applied the Xilinx Temac patch in it. So could you please give me some 
detailed guidance on how to successfully apply the driver for SystemACE? 
Thanks a lot in advance.

Regards
Ming

Do you have a Xilinx ML403 board?

Does your kernel boot (show messages) without the SystemACE driver? Try
that first. It should boot and panic at the point where it tries to find
the root fs. Once you have reached this stage, you can then include the
SysAce driver.

> My linux version is 2.6.16-rc5. 
I don't think there is any issue with your kernel version apart from the
fact that 2.6.16- series posed considerable problem for me when trying
to configure a serial shell. The serial driver is BUGGY. So I use
2.6.17.1 (latest release).

Is it possible for you to send me this Temac patch?

So could you please give me some

I am in the process of publishing a detailed article/tutorial on
compiling 2.6 kernel for the Xilinx MLxxx boards. Will send you the link
shortly!

Re: Xilinx SystemACE driver for 2.6

[Ming Liu]

Hello Ameet,

>Do you have a Xilinx ML403 board?

Yes, I have ML403 board. The reason why I rename the xparameters_ml300 as 
xparameters_ml403 is that EDK generates the driver for ML300(the xparameter 
header file is xparameters_ml300).

I did try that. There is also no information. At that time, I guessed that 
it was because of the missing of SystemACE driver.Do you think is that the 
problem of others, for example the kernel? Before I use 2.6 version, I have 
successfully booted a linux 2.4 from CF card.

I use this version only because I want to implement the Temac driver in the 
link of 
http://ozlabs.org/pipermail/linuxppc-embedded/2006-March/022365.html It 
looks that the patches are specific for that version.

There is nothing special in the TEMAC driver that binds it to 2.6.16-rc5.
The patch was generated against and tested with that kernel version. That's all.
The patch will probably not apply cleanly to the more recent kernels. But
otherwise it should work.

In other words, feel free to use that TEMAC patch with the recent kernel.

Thanks,
Andrei

    I am trying to get a local link version of the hard TEMAC that is
part of the V4 FX FPGA working against a 2.6 Kernel. Would this be an
appropriate patch for that ?
    Is it even close ?

    There are so many different Xilinx (and other) TEMACs floating
around and so many permutation of those that my head is fogged in.

Quick comment on your article; unless you're using a microdrive;
*PLEASE* don't recommend using compact flash as swap space.  Flash
technology has limited write cycles (on the order of 100k to 1M cycles
per block).  Using it as swap is a great way to kill the lifecycle of
your device.

(the ML300 ships with a microdrive; the ML40x ships with a regular CF card)

I know the previous article also recommends a swap partition, but
Linux will happily run without swap.

Cheers,
g.

Yes. I noticed that in the original demo Linux of MontaVista shipped by

Re: Xilinx SystemACE driver for 2.6

[Ameet Patil]

Hi Grant,
    I totally agree with you. What you say is correct. It will 
definitely kill the CF card. I use a XUPV2PRO board which doesn't come 
with a microdrive and for my research SWAP is a must. :-)

However, I shall add a NOTE in the article mentioning the same.

Thanks a lot,

Xilinx BSP for linux 2.6

[Ming Liu]

Dear Ameet,
Now I am using your patch for SystemACE in Linux 2.6. My linux version is 
2.6.16-rc5 and I have applied the patch for SystemACE and Temac. 

When I generate BSP in EDK, how can I implement it in my linux kernel? I 
know the EDK BSP is for Linux 2.4 and the directory stucture is the same as 
2.4(e.g. arch/ppc/platform/xilinx_ocp/......) But in 2.6, the directory 
tree is different and I cannot simply copy and replace the original files 
there. Also, there is a file called xparameters_ml403.h in Linux kernel but 
in BSP there is only xparameters_ml300.h. Shall I rename the 
xparameters_ml300 as ml403, or configure the board as ml300 in menuconfig? 
In these xparameters files, the peripheral addresses are defined. How can I 
include these xparameters defination in the kernel? It looks complicate and 
you didn't mention how to replace these files in your article. So if you 
can provide some guidance, I will appreciate a lot because it will save me 
much time. 

By the way, I am still waiting for the last part of your article. Where are 
they? :)

Thanks for your help.

Regards
Ming

Re: Xilinx BSP for linux 2.6

[Ameet Patil]

Hi Ming,
  I DONOT have a ML403 with me. But does Xilinx EDK generate
xparameters_ml300.h in the BSP instead of xparameters_ml403.h for the
ML403 board?

Anyway, for linux 2.6 theres no xilinx_ocp directory in the code tree.
You need to just copy the xparameters_ml300.h file (if that is what
xilinx EDK generates) as xparameters_ml403.h in
arch/ppc/platforms/4xx/xparameters/ folder. Configure the kernel as ML403.

Like I said to you before, if you want to get started quickly and
without much headache.. then please go step-by-step. Try the things I
mention in the article PART I without applying any patches.

http://www.linux.get2knowmore.com/2006/06/30/quick-guide-linux-26-on-xilinx-virtex-ii-pro-boards-part-i/

Then if your kernel boots and shows some messages, it would be much
easier to relate to problems after applying patches.

Please DONOT hesitate to ask further clarifications!

Xilinx SystemACE driver for 2.6

[G.Muruganandam]

[-- Attachment #1: Type: text/plain, Size: 479 bytes --]


Hello g,

I am looking for the answer to your question regarding the System ACE 
driver under 2.6
posted in the linuxppc-embedded@ozlabs.org.

Pl let me know whether it is ported to 2.6.

If yes, Would it be possible to share the source code?

Looking forward to hear from you.

Thanks
G.Muruganandam

Has anybody ported the SystemACE driver from 2.4 to 2.6 yet?  If so,
where can I pull a patch from?  Otherwise I'll start work on it.

Thanks,

Along these lines, has anybody done any work to improve the overall
performance of the driver?

What kind of throughput are you seeing on your systems?
