Announcement: MPHY now supported in mpc860sar

[Alex Zeffertt]

Just a quick note to say that multi-phy is now supported by the
mpc860sar ATM driver, thanks to a patch by Rodolfo Giometti.

This is very exciting news! (well, for me it is)

How many PHY's in parallel are we talking about here?

Thanks,
Gilad.

[Alex Zeffertt]

It is currently only supported in SAR mode, and in that mode there is an
upper limit of 4 UTOPIA phys.  However, there's no reason that support
can't be added for MPHY in ESAR mode - in which the limit is 31 phys.  I
suspect that adding such support would be easier now that Rodolfo has
done most of the work.

PS I'm not the expert on this.  Rodolfo's sourceforge username is
"zaigor".

Okay. Thanks.

And now for my next question - Do you think the driver
should run on the 82xx family of chips? (e.g. 8260 and the likes)
these guys have 2 Utopia-II ports with support for up to 31 devices
per port. Coupled with this software, it could make for a highly
efficient DSLAM.

All I know  is that it won't run on the 8260 "as-is".  Sorry, you'll
have to RTFM.  (The chapter on ATM is only ~180 pages :-).

Quick ad-hoc question?

[Zoran Stojsavljevic]

Hi to everyone,

On our ADSL project we are using GlobeSpan Octane chipset. If anybody
uses Octane, did you ever try to set up some loopback inside Octane's DSP?

If yes, the question is how to do this (via GS APIs, but which)?

Looking for quick answers...

[Zoran Stojsavljevic]

Quick question to you all... I walked through Pete's 8260 ATM driver,
and I saw (as far as I can understand) that Pete's driver is set to
support single PHY mode.

So, the question here is: do we need Rodolfo Giometti's patch to be
applied to mpc8260 ATM driver?

It is obvious that different set-up should be applied for mpc8260 ATM
driver MPHY mode anyway...

Thank you for answers in advance.

Zoran

I wouldn't imagine that the patch would apply to the mpc8260 driver and
work.  However, it would probably be useful to look at it for pointers
if you were thinking of porting MPHY support to the mpc8260.

BTW, to get the patch try

cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/mpc860sar checkout -A atm  # Top of tree is now MPHY
cd atm
cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/mpc860sar diff -u -r single-utopia-phy  # compare with SPHY branch

Re: Announcement: MPHY now supported inmpc860sar

[Zoran Stojsavljevic]

Antonio,

Thank you for your reply... Just In Time... I needed somebody to verify
my thoughts. :)

For the future users... Few thoughts...

About I/Os...
Just to recap few things about MPC8250 ATM driver... Under
CONFIG_ATM_VADS there are port A, C and D pin definitions, relevant for
Utopia L2 interface (I think, file is utopia.c) ... So these must be
carefully considered, when connecting with the PHY... The best is to use
generic VADS phy. FCC1 is used, and port pins are set for 8 bit Utopia
I/F, although remaining 8 bits Utopia remains set, I cleared them.

The additional things to consider is which BRG to use as internal, and
which as external. You might need to redefine BRG accordingly!

Regards,
Zoran

MPHY supported in mpc8260sar

[Zoran Stojsavljevic]

Hello to all,

I finally achieved multiphy mpc8260sar (with some limitations).
The driver is able to support 8 PHYs (one PHY per unique priority).
The driver is developed out of Peter's McCormick single PHY version.

For some unknow reason I could NOT achieve MPHY support with
only one priority (for example highest PRIority 0). In order to make
MPHY to work correctly I assigned a unique priority per PHY. With
8 PHYs the mapping looks like: PHY0/PRIO0, PHY1/PRIO1...
PHY7/PRIO7, eg. PHYx/PRIOx, where x is in range [0..7]!

The another limitation is that I did NOT fix the VP range, eg. I am using
only VP0 (one VP) with different VCs, where least three (3) significant
bits of each VC assume the selected PHY. In other words, I am using
8 nas interfaces, and VCs (decimal radix) from 40 (0x28) to 47 (0x2F),
where VC 40 is attached to PHY0, VC 41 to PHY1... VC47 to PHY7.
While issuing ATM xmit command I am deriving least three significant
bits of currently processed VC and I'm putting them to the
COMM_INFO words (offset 0x86, field PHY#), described in section
30.14 of MPC8260 PowerQUICC II Family Reference Manual
(Revision 1, date 05/2003).

If you all find this info of (some) interest, I can do the patch (against
latest
version in CVS) so we can store this limited edition of the MPHY version
under the mpc8260sar driver project.
