Compile time error, compiling Xilinx Linux 2.6 for XPS LLTEMAC

All,

that should be a small problem, and i think that its solution should be simple,

I generate a base system using EDK 9.2.02 , the base system contains XPS_LL_TEMAC , MPMC and other components,
I generate the software libraries and copy xparameters file into proper kernel folder. I configure that kernel and add kernel support for XPS_LL_TEMAC.

while doing make I encounter this error:

arch/ppc/syslib/virtex_devices.c:455: error: 'XPAR_LLTEMAC_0_LLINK_CONNECTED_FIFO_INTR' undeclared here (not in a function)

I think that this definition should be available in xparameters_ml403.h file but i see that there is no such definition. 
I added a dummy definition for myself there to complete kernel compilation, don't know the correct value for it of course.

thanks

That interrupt is defined if you build a xps_ll_temac with the
xps_ll_fifo interface. Since you already stated that you're using the
mpmc, I'm going to assume that you have it connected to a SDMA
controller on the mpmc. As such the driver should be looking for that
definition, and not the FIFO interrupt. I don't have your version of the
virtex_devices.c to have a reference as to how the platform device is
being defined, so hopefully either Stephen N can chime in w/ more
information, or point me to the version of the virtex_devices.c that
you're using and I can try to provide some more assistance.

Ah, thanks mike...  you knocked the answer loose out of my brain...

In EDK 9.2., the ll_temac generates either SDMA or FIFO defines, as necessary.
The platform data structure contains entries for both, with the correct ones being ignored.  In order to get the code to compile, there are some defines in xparameters.h which have:

#ifndef XPAR_LLTEMAC_0_LLINK_CONNECTED_FIFO_INTR
#define XPAR_LLTEMAC_0_LLINK_CONNECTED_FIFO_INTR 0xdeadbeef
#endif
#ifndef XPAR_LLTEMAC_0_LLINK_CONNECTED_DMATX_INTR
#define XPAR_LLTEMAC_0_LLINK_CONNECTED_DMATX_INTR 0xdeadbeef
#endif
#ifndef XPAR_LLTEMAC_0_LLINK_CONNECTED_DMARX_INTR
#define XPAR_LLTEMAC_0_LLINK_CONNECTED_DMARX_INTR 0xdeadbeef
#endif

after including xparameter_ml403.h 

I'm guessing maybe you overwrote the xparameters.h file and got rid of these redefines?  You can define it to be whatever you want, since the value will be ignored if you are using SDMA.

In EDK 10.1, the BSP generator will always generate all the defines (even ones which are not sensible in the current configuration), which avoids the above annoyances.

Ok, thanks for guidance,

by the way it is interesting for me to hear about EDK 10.1 from u steve, 
EDK 9.2 has been around just for a little time and you are going to 10.1?

What about future plan of xilinx about Virtex-5 FX? does this tool consider that? 
the future plan is really important for our development team. let me give a simple example, our dev team worked on the design of our system based on PLB and OPB buses for some thing near 6 month, just then EDK 9.2.02 released and suddenly we forced to change all of the designs and to define new activities specially focusing on MPMC. we did never consider MPMC before, but the release of EDK 9.2 changed every thing. 

Now, that would be nice, if we can know your future plan a little, that would help us to generate correct and real gant charts. and to assign human resources correctly. this is also true for the project budget. We know that Virtex-5 devices are really capable of doing better things than Virtex-4, specially the PCI express option is great and very usable for us, but we have not moved to virtex-5 yet, because there is no FX series or at least we do not know your plan about it. Our managers we seriously asking us if we have to move to Virtex-5 soon, we did not have any reasonable answer for them because we do not have any info from u at all.

thanks

You should be able to contact your Xilinx sales rep for details on
Virtex-5 FX as well as roadmap information.  The Virtex-5 FXT product is
coming soon and should be announced within the next month or so.  I
can't provide details, but your technical sales contact should be able
to give you more info on timelines etc...

 

As for EDK releases, Xilinx typically releases two per year (e.g., EDK
9.1 and 9.2 were both released in 2007).  EDK 10.1 is scheduled for
release before summer, and should be the only release in 2008 (with some
service packs throughout the year).   There shouldn't be any major
differences from EDK 9.2.02 regarding IP/drivers.

 

-Rick

Xilinx Linux 2.6 for XPS LL_TEMAC and LL_FIFO problem

[Mirek23]

Dear All,

I have done a design using EDK 8.2 using Hard_Temac IP component. In the EDK
9.2 there is a new idea to use ll_temac in conjunction with ll_fifo or
ll_dma. So far I was using happily the linux kernel by Grant Likey.
Unfortunately it does not deal with ll_temac. I have download the kernel
from git.xilinx.com.

I have tried to build the kernel 2.6.26  (by xilinx) but it seems to be that
it is not well prepared for ll_fifo.
I have noticed that in drivers/xilinx_common there are files related to
ll_fifo but in the drivers/Makefile there is no rule to build ll_fifo. The
same refers to the file arch/ppc/syslib/virtex_devices.c ->  there are no
entries for LL_FIFO. I have the impression that one can use only LL_DMA but
not LL_FIFO.

Does anybody has modified the kernel to deal with LL_TEMAC together with
LL_FIFO?
I will be grateful for any hint.

Best Regards

Mirek

[Koss, Mike (Mission Systems)]

Mirek,

I'm currently using the driver (CONFIG_XILINX_LLTEMAC) with the DMA
portion with no problem, which is what you kind of eluded to. From what
I've seen, the drver source does support the FIFO portion. It just
relies on having the proper definition for the TEMAC in either the DTS
or the xparameters.

I'm currently using the 2.6.26-rc8 kernel (HEAD?) from git.xilinx.com as
well, and mine builds with no problem for arch/ppc. Yes, I still have
not moved to arch/powerpc. I will be moving to the new arch in the very
near future. (My current test system is actually a mish-mash of 2.6.22
w/ the driver from xilinx-2.6.26 tree).=20

Are you using arch/powerpc or arch/ppc? Are you generating your DTS from
your MHS file using the bsp generator for EDK on git.xilinx.com? Is this
for one of the reference boards (ML403, ML405, etc)? What is the problem
that you're having with the build of the kernel?

Dear All,

I have done a design using EDK 8.2 using Hard_Temac IP component. In the
EDK
9.2 there is a new idea to use ll_temac in conjunction with ll_fifo or
ll_dma. So far I was using happily the linux kernel by Grant Likey.
Unfortunately it does not deal with ll_temac. I have download the kernel
from git.xilinx.com.

I have tried to build the kernel 2.6.26  (by xilinx) but it seems to be
that it is not well prepared for ll_fifo.
I have noticed that in drivers/xilinx_common there are files related to
ll_fifo but in the drivers/Makefile there is no rule to build ll_fifo.
The same refers to the file arch/ppc/syslib/virtex_devices.c ->  there
are no entries for LL_FIFO. I have the impression that one can use only
LL_DMA but not LL_FIFO.

Does anybody has modified the kernel to deal with LL_TEMAC together with
LL_FIFO?
I will be grateful for any hint.

Best Regards

Mirek

RE: Xilinx Linux 2.6 for XPS LL_TEMAC and LL_FIFO problem

Hi Mirek,

We are not currently testing the LL TEMAC driver with the LL FIFO. We
only test with the DMA configuration. I also realize this may not be
documented that well and we may need to work on that.

Our reasoning is that in the Virtex5 FXT devices the DMA is hard so that
it does not cost any more LUTs to use the DMA and most people want the
performance. =


Is there a specific reason you're wanting to use the LL FIFO rather than
DMA as this information might help us in the future?

We would welcome any patches to the driver if LL FIFO is a needed
feature.  Patches can be sent to git@xilinx.com.

Thanks,
John

RE: Xilinx Linux 2.6 for XPS LL_TEMAC and LL_FIFO problem

[Mirek23]

Hi John and Mike,

Thank you for your reply. We have modified out FPGA design and now we have
LL_TEMAC with LL_DMA component connected instead of the LL_FIFO. Before
building linux kernel we have tried to build the u-boot (downloaded from the
xilinx-git tree).

It was relatively easy to build u-boot which has the ll_temac with ll_dma
support.

next we have tried to run u-boot on our ppc (virtex-4 FX12). All went fine
till the moment to establish the communication with the network.

I put some debug messages to the xilinx ll_dma and ll_temac drivers and we
have found that u-boot hangs 
during dma initialisation:

more specifically in the function calls :
       XLlDma_Initialize(XLlDma * InstancePtr, u32 BaseAddress) 
               XLlDma_Reset(XLlDma * InstancePtr) 
                         XLlDma_mBdRingSnapShotCurrBd(TxRingPtr);

Do you have any idea what could be wrong with dma initialization?

Best Regards

Mirek

{resend as I forgot to send to the mailing list)

Hi Mirek,

Since this is a u-boot issue, we can move this conversation off this
list.

The u-boot that is in the git repository has not been tested on the
Virtex4 platform.

I have only tested on the ML507, Virtex 5 platform.

There's not a ML403/ML405 board supported in our git tree, so I'm
curious what you did to try to build it for V4.

There are differences between V4 and V5 with the DMA as it's hard in V5
and hangs off the DCR bus of the processor.

The kernel itself is running on both the ML405 and the ML507, but not
yet with u-boot.

Thanks,
John
