Xilinx XPS_LL_TEMAC vs PLB_TEMAC

[Mohammad Sadegh Sadri]

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...

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.

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?

  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.

  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
