Ming/Rick,

I tried setting the speed to 1000 as below, but it did not change the
result.  I also tried Rick's new adapter.c with the same results.  Changing
the hard_temac_v3_b to hard_temac_v3_a was the change I needed.
Unfortunately, the speed of the network is much slower now.  I switched to
DMA and then changed the Linux drivers for the DMA & TEMAC v2 to v3.

I have my own program to test performance.  It seems everything is so slow
it does not every complete to give me the statistics.  My ping are also
slower.  I used to be able to ping my computer and get 0.6-0.7 ms times.
With the DMA and TEMAC v3 I am now getting 1.8 ms times.

I am now not sure if it is my build or my PPC design.  For the PPC design I
have a minimum PPC with OPB-RS232, PLB-DDR, and PLB-TEMAC.  I use all the
defaults from BSB except I check use interrupt on the RS232 and TEMAC.

Any suggestions?

Thanks,
Glenn

In fact, the old cores of TEMAC(plb_temac 2.00 & hard_temac 1.00) also
support DMA. But of course the 3.00 cores are prefered because of other
improved features.

I also had such a problem before. To solve such a problem most quickly, you
can just specify a fixed speed (like 1000Mbps) in adapter.c file. In this
file, after the line of "/* Get current link speed */ (around L378) and
"phylinkspeed = (RegValue & MARVELL_88E1111_LINKSPEED_MARK)>>
MARVELL_88E1111_LINKSPEED_SHIFT;", I just add and specify the speed as
"phylinkspeed = MARVELL_88E1111_LINKSPEED_1000M;" Of course with this
method, the speed cannot be auto-negotiated any more.

Another hints: I remember that there is another post from Rick on the
updated "adapter.c" a few days ago. Maybe that could solve your problem. I
didn't try that before. So if you will try, pls let us know the result. :)

BR
Ming

* Linux w/ML403 PLB TEMAC

I am trying to get Linux up on my ML403 board with the PLB TEMAC with
SGDMA.  I am almost there and am not sure where to go now.  I have seen
many posts on this from Robert, Ming, and Rick.  Hopefully somebody know
the answer.  Since I am going to detail how I got to where I am it can be
somewhat of a guide for others (unless I am doing something really wrong).

1.  I started with Linux 2.6.19 from kernel.org.  I copied over the
xparameters_ml40x.h file to xparameters_ml403.h in
arch/ppc/platforms/4xx/xparameters.  Setting up my kernel configuration and
downloading to the board everything worked OK.  ** I did not have the TEMAC
configured or as part of my PPC project.

2.  Next I created a new PPC with the PLB TEMAC and applied all four kernel
patches from PAULUS
(http://source.mvista.com/~ank/paulus-powerpc/20060309/).  A couple of the
files did not patch completely, so I had to do it by hand.  Recompiling the
kernel (with the TEMAC configured to on) I now had network support.

3.  The speed of the network was very poor.  I wanted to implement DMA for
the TEMAC.  I created a new PPC with BSB using DMA on the TEMAC.  Kernel
recompilied without a problem, but upon starting the kernel I got:

Going back through previous posts I found that I need to upgrade the kernel
driver for the DMA and TEMAC to V3.

4.  From EDK 8.2.02i  SP2.4+0 I copied the files from the BSP to the kernel
using the following steps.
      a.  Copied the files from linux\drivers\net\xilinx_temac of the BSP
to drivers/net/xilinx_temac of the kernel preserving the Makefile from the
kernel.
      b.  To adapter.c I remove the #include xilinx_devices.h and added
#include linux/platform_devices.h and #include platforms/4xx/virtex.h
      c.  To adapter.c I changed all instances of CHECKSUM_HW to
CHECKSUM_PARTIAL
      d.  To the Makefile in linux/drivers/net/xilinux_temac I added
xtemac_stats.o
      e.  I removed the #include xparameters.h from xtemac.h

      f.  Copied the files from linux\drivers\xilinx_common of the BSP to
drivers/xilinx_edk of the kernel.
      g.  In the drivers/xililnx_edk Makefile I removed the line containing
xdma_channel.o xdma_channel_sg.o
      h.  In the drivers/xililnx_edk Makefile I commented out the line with
xlinx_syms.o

5.  Recompiled the kernel I everything was OK.  Starting the kernel
everything looked OK:
[    3.758994] XTemac: using sgDMA mode.
[    3.803211] XTemac: using TxDRE mode

[    4.153560] eth0: XTemac id 1.0f, block id 5, type 8

6.  I am using busybox 1.2.1 which worked fine previously configuring the
network.  Now when I execute ifconfig I get the following problem:
[   12.228721] eth0: XTemac: Options: 0xb8f2

Anybody have an suggestions?
