Xilinx XPS_LL_TEMAC vs PLB_TEMAC

[Koss, Mike (Mission Systems)]

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
