Hi all,
does anyone have working driver for xps_ll_temac unsing sg dma and checksum=
offload on rx and tx ??
I use the xlnx kernel with ARCH=3Dpowerpc and a device tree generated with=
the gen_mhs_devtree under EDK 10.1
I don't know what's wrong but i can't get or send anything even the speed =
is only 10 Mb/s !
that's what i get when the kernel starts...

Hi Simon,
I have not done testing of this driver with checksum offload. I do test
the driver in an automated test, but not in checksum offload mode, I
need to add that test. =
I did receive the following patch and applied it to the Git server so I
think Johann did some testing with checksum offload. That may have been
with arch/ppc rather than arch/powerpc, not sure.
I noticed that you have uboot working with LL TEMAC and it must be using
DMA SG as it's running on the same h/w. I just got thru hacking together
a rough polled mode LL TEMAC driver to support uboot and it's working,
but not cleaned up. Just curious on your experience in that area.
Thanks,
John Linn

Subject: [PATCH] Xilinx: LL TEMAC: Fix checksum offload
The LL TEMAC is generating the wrong checksum when TX hardware checksum
is enabled. This is mainly due to two issues:
- CHECKSUM_COMPLETE can only be used on RX PATH, CHECKSUM_PARTIAL must
be used instead.
- Checksum index offsets are being calculated wrong.

Hi John,
I found a driver in the uboot ml from Yoshio Kashiwagi (Thanks :)
link:
http://www.nabble.com/Xilinx-PowerPC-XPS_LL_TEMAC-driver-td16893860.html#a1=
6908888
i didn't know how it works but it uses memcpy on tx and NetReceive() from u=
boot net.c ...
I have to achieve an average speed of 20 MB/s. I hope it works ! Have you g=
ot some facts ?
So, i don't know what i should do. I thought that xilinx drivers suppots th=
ere hw ! Should i try to integrate xilinx EDK generated drivers into xlnx k=
ernel tree ? and how ?
My computer and the temac are connected to a 1Gb switch and the led is blin=
king when the temac send something but not the led of my computer! as if th=
e switch does not his job ! invalid frames ? is possible ? (i should have a=
break...)
best regards,
Simon

Hi Simon,
With EDK10.1, xps_ll_temac, ARCH=powerpc, I've reached ~17Mo/s with netperf
(UDP) and ~30 Mo/s in raw packet mode.
Are you using Xilinx evaluation board? If not pay attention to the PHY
controller. (you may not use MARVELL_88E1111_PHY define)
To check if you have some issues with checksum offload, you can use
Wireshark (network analyzer). With this tool you will see your frames and if
they are sent properly.
Best regards,

I have to achieve an average speed of 20 MB/s. I hope it works ! Have you

So, i don't know what i should do. I thought that xilinx drivers suppots

kernel tree ? and how ?
My computer and the temac are connected to a 1Gb switch and the led is
blinking when the temac send something but not the led of my computer! as if
the switch does not his job ! invalid frames ? is possible ? (i should have

Hi Simon,
I have not done testing of this driver with checksum
offload. I do test
the driver in an automated test, but not in checksum
offload mode, I
need to add that test.
I did receive the following patch and applied it to the Git
server so I
think Johann did some testing with checksum offload. That
may have been
with arch/ppc rather than arch/powerpc, not sure.
I noticed that you have uboot working with LL TEMAC and it
must be using
DMA SG as it's running on the same h/w. I just got thru
hacking together
a rough polled mode LL TEMAC driver to support uboot and
it's working,
but not cleaned up. Just curious on your experience in
that area.
Thanks,
John Linn

Subject: [PATCH] Xilinx: LL TEMAC: Fix checksum offload
The LL TEMAC is generating the wrong checksum when TX
hardware checksum
is enabled. This is mainly due to two issues:
- CHECKSUM_COMPLETE can only be used on RX PATH,
CHECKSUM_PARTIAL must
be used instead.
- Checksum index offsets are being calculated wrong.

Hi all,
does anyone have working driver for xps_ll_temac unsing sg
dma and
checksum offload on rx and tx ??
I use the xlnx kernel with ARCH=powerpc and a device tree
generated
with the gen_mhs_devtree under EDK 10.1
I don't know what's wrong but i can't get or
send anything even the
speed is only 10 Mb/s !
that's what i get when the kernel starts...
