Xilinx XPS_LL_TEMAC vs PLB_TEMAC

[Mohammad Sadegh Sadri]

[-- Attachment #1: Type: text/plain, Size: 500 bytes --]


Hi All,

As you know Xilinx PLB TEMAC is a module which connects Hard TEMAC in Virtex-4 FX devices to PLB bus,
now, in the new release of EDK , EDK 9.2 Xilinx has added a new interface core , which is called XPS_LL_TEMAC and has a different structure than normal PLB TEMAC. spacially it has some additional data transfer buses. 

Now the question is,... is there any linux driver available for this new core?

thanks

Yes there is, but I had to use the git sources at:

git.xilinx.com

thanks for you reply david,

As far as I know the Linux driver for Xilinx PLB TEMAC was two parts : 1- adapter.c and 2- the rest of the driver files

Only adapter.c was really a linux related file and the rest of the files were Xilinx generic driver code for PLB TEMAC.

correct?

then now, I know EDK 9.2 generates the needed Linux support package and needed related files, so if this is the case can we use these files as the needed driver in our linux kernel?

by the way, i did never hear about this git repository before...can you describe us, where is it and how we can access it and which projects are now hosted by it?


thanks

In case anyone is interested, I'm currently working on an
almost-kernel-ready version that will be self-contained based on the
LL-DMA version (the native MPMC port, not the PLB). It's based upon the
old adapter from MontaVista, that I originally ported to 2.6 and the
MPMC2. Unfortunately, it won't be ready for another few weeks since I'm
working on hardware images currently.

RE: Xilinx XPS_LL_TEMAC vs PLB_TEMAC

[Stephen Neuendorffer]

Basically, git.xilinx.com has a tree with most of the xilinx-related
support already integrated and ported forward to a current kernel.  It
also includes ongoing work to unify microblaze and powerpc device
drivers through flat device trees.

See:
http://www.mail-archive.com/linuxppc-embedded@ozlabs.org/msg28690.html

To use the git.xilinx.com tree you should *not* generate the driver code
directly into the Linux tree.  Instead, you should generate the driver
code in a dummy directory and copy
arch/ppc/platforms/4xx/xparameters_ml*.h into the kernel tree.

The BSP generation process is designed older 2.6.10-era kernels and will
not work with recent kernels. =20

Hi

Well, As you know, we now need a PLB version, XPS_LL_TEMAC is connected to PLB not MPMC2...yes I remember those days of Xilinx GSRD and MPMC2 however it seems that the current architecture has slight changes. 

about the git repository of Xilinx, Although I do not believe on it, I'll give it a try...thanks for info.

well, what about Grant Likely... and his git tree?

Actually, with the MPMC3 the XPS_LL_TEMAC still can directly connect to
the MPMC. You set one of the ports' type to SDMA and it instantiates
what is similar to the old CDMAC.

So, in this case, our base system, created with EDK 9.2 will not be the same as previous systems, as shown in 
http://www.xilinx.com/esp/wired/optical/xlnx_net/mpmc.htm
PLB and OPB usage is limited to a small area of design...

RE: Xilinx XPS_LL_TEMAC vs PLB_TEMAC

[Stephen Neuendorffer]

The LL_TEMAC can be connected in two topologies.  One connects the
locallink directly to the SDMA port of the MPMC3.  The other topology
connects to a PLB46 bus using an XPS_LL_FIFO, which (most likely)
connects to the plb bus port of the mpmc.  The easiest way to decipher
the connection pattern is to use Base System Builder in EDK to generate
both topologies (which is determined by the 'use DMA' parameter when
selecting the LL_TEMAC device.  The Linux driver in git.xilinx.com
supports both topologies.

USB device for ppc440epx

[Leonid]

Hi:

does somebody have code example for USB 2.0 device implementation for
ppc440epx, preferably Mass Storage device, but any will do.

If not for ppc440epx (Sequoia board), ppc440ep (Yosemite) code will also
help (according to CPU user manual USB device interface is practically
the same).

If this is already present in Linux kernel tree (from what version?),
where it is located?=20

Thanks,

Leonid.

USB mass storage works on 440EP already.  It'll be in 2.6.25 in
arch/powerpc.  I would suspect 440EPx works as well.

BTW, it's considered impolite to hijack a thread to ask a completely
unrelated question.

Hi, Josh:

Ooops, I didn't notice I have hijacked someone's thread, I thought I
created a new one. I am very sorry if I have done so, I'll be more
careful.

Regarding USB Mass Storage there are device drivers (Host side) of
course. However I am asking regarding USB device implementation itself.
Can you point me to source files where this implementation is present
for 440ep/epx?

Linux has several examples of devices (like Zero Gadget) and I have used
it with ARM CPUs. But I am not sure it is working on 440epx also.

Thanks,

Leonid.=20
