RE: question about Linux 2.6 with Xilinx ML-403

[Martin, Tim]

Grant,

I know I could probably figure this out by looking at the GIT tree
directly (which I'm planning to do) but could you summarize how much
(which devices) of the ML-403 is supported by your patches?

Serial? (which Xilinx core)

Ethernet? (Hard-Core PLB TEMAC?, Soft-Core PLB EMAC? Localink TEMAC? Is
10/100/1000 supported, or is there only 1 rate e.g. 1000 supported?)

Anything else (GPIO buttons/switches?)

Thanks,
Tim

No.  I've ported the 2.4 driver, but I haven't got permission to
release it yet.  (I'm a contractor; I don't own any of the work I do)

I checked both Torvalds' tree and Paul's tree. I see the defconfig file
for both ml300 and ml403, but I don't see any source files related to
either ml300 or ml403 under the <platforms> subdirectory. Have you done
a complete BSP for either ml300 or ml403?

Yes, we have a driver for the PLB TEMAC (different than the GSRD LL
TEMAC) for Linux 2.4 (MontaVista Linux 2.4.20) that's shipped in EDK
8.1.1, and MontaVista is on the verge of publishing a driver for PLB
TEMAC for Linux 2.6. (I believe it came across this mailing list a few
weeks ago)

The montavista softcore driver.  Has someone written a driver for the
TEMAC yet?

Hey cool!  Yeah I just found it now.  I haven't been following the
list very closely the last month or so.  I'll try it out in short
order.

Thanks Rick!

Which 2.4 driver - there's the "Montavista" one for the softcore PLB
EMAC, and there's also one for the hardcore PLB TEMAC that gets
distributed with the GSRD.

I believe they are now in Linus' mainline git tree.  If not, they are
in Paul's powerpc git tree.

BTW, please CC the linuxppc-embedded mailing list when emailing me directly=

Hi, Grant,

Thanks for the information.

I just checked out Linus's GIT tree from
rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
linux-2.6.

Where is the location for Paul's GIT tree ? Just curious ...

HI, Grant,

I downloaded Paul's git tree as you suggested.

It seems that the defconfig for ML-403(in Patch [9/9]:
http://patchwork.ozlabs.org/linuxppc/patch?id=4226 ), the tri-mode
Ethernet MAC on Virtex-4 FX12 on the ML-403 board was disabled.

Is this Ethernet device supported by this patch ?

Thanks.

No, sorry.  I'm still trying to get permission to release it (it's

Re: question about Linux 2.6 with Xilinx ML-403

[-- Attachment #1: Type: text/plain, Size: 1431 bytes --]

HI, Grant,

It looks like that the patch for ML-403 in Linux 2.6.17 kernel(I
downloaded from Linus git tree) does not have the directory :
./arch/ppc/platform/4xx/xilinx_ocp like the one in the 2.4.30 kernel.

And also, I saw this thread: "Migrate Xilinx Vertex support from the OCP
bus to the platfom bus"

    http://patchwork.ozlabs.org/linuxppc/patch?id=3933

Does it mean all of onchip peripherals for Virtex-4 FX must reside on
the PLB bus instead of OPB (OCB) bus ?
(i.e. during the process of creating the ref design for Linux using
Xilinx Platform studio, I have to select PLB peripherals instead of OPB
peripherals. Is is correct ?)

BTW, do you have a sample ref design for ML-403 board for Xilinx
Platform studio ?

Thanks for the help.

That's right.  AFAIK, The 2.6 kernel is not yet supported by the
Xilinx EDK tools; and so it cannot generate a 2.6 BSP.  If you want to
use the generated BSP; use the montavista 2.4 kernel.

No.  Platform bus is a Linux construct to make it simpler to handle
"directly attached" devices.  ie. Anything that the processor can
access directly w/o PCI et all.  OPB and PLB devices are both
'platform' devices in Linux 2.6 terminology.

No, use whatever peripherals you want (either PLB, or OPB).  Just be
prepared to port device drivers for anything beyond a serial port.

Why not use the ref design that Xilinx provides?  (I have a number of
designs that work; but most of the time I use the ML403 ref design
because I know it's proven)
