Intel-e1000 for Linux 2.0.36-pre14

Intel-e1000 for Linux 2.0.36-pre14

[Ofer Fryman]

I managed to compiled e1000 for Linux 2.0.36-pre14, I can also load it
successfully. 
With the E1000_IMS_RXSEQ bit set in IMS_ENABLE_MASK I get endless interrupts
and the computer freezes, without this bit set it works but I cannot receive
or send anything.

Does any one have a clue?.
Thanks
Ofer

Intel refuses to provide complete documentation for any of their ethernet
cards.  I recommend purchasing alternative products from vendors like 3com
and National Semiconduct who are cooperative in providing data needed by
the development community.

Well Intel has been a continual contributor to Linux and BSD. Somebody
is not getting to the right person. There are lazy people at all
companies. 

Here is a compressed `grep` of linux-kernel mail headers from Intel
who had something useful to say during the past year. Maybe you
can ask one of them for the information you need? You just need to
find an advocate at a big company.

Sorry, I don't believe that that this is correct in this case. I spoke on the
telephone with the "Manager for Open Source Systems", and the concept of
releasing documents to that a driver could be written whose source would be
available was a concept too far. He kept on asking about NDAs- I kept on
saying, yes, I'll sign an NDA (presumably so knowledge of advanced features,
such as VLAN taggging, e.g., would not be released if they did not want it to
be)- but the basic driver source would have to be OPEN! (this was for *BSD,
but that's the same as linux in this case- we *all* want the damned source
open). No meeting of minds. I have been trying this on and off for two years
so that I can properly support the Wiseman && Livengood chipsets in *BSD. No
luck, ergo, reverse engineering of what little they release with the Linux
driver is the order of the day still. The Linux driver, btw, is pretty clearly
a port of an NT driver- which is quite amusing.

FWIW.....I just think that the overall company policy within Intel, much like
that of NetApp and others, is, "Open Source? Well, maybe, err,umm.. "...  It's
just not that important to them (as a company, they think). That said- if you
can get access to said documentation (which I understand comes in a certain
notebook that indicates releasing outside of Intel is a firing offense)- more
power to you!

The way I've gotten so-called proprietary information in the past is
to let the world know that "boneserver.analogic.com" 204.178.40.210 is
an open ftp site in which I don't even log what's uploaded and downloaded.

I check it once or twice a week to see if somebody has sent me anything
of interest. Sometimes, persons unknown to me, have deposited information
that I need. 

Now I seem to need some programming information on the Intel e-1000.
I'll keep you informed if anything turns up.

I need a giga fiber PMC cards for linux2.0.36-pre14, the only cards I know
are either Intel based or level-one lxt-1001 card, the level-one lxt-1001
has very bad performance so I cannot use it.

Thanks,
Ofer

Well, 2.0 kernels are sufficiently old that there's little likelyhood of
newer gige drivers supporting them unless you do the work yourself.  My
personal recommendation would be moving to a 2.2 or 2.4 kernel and using
an Acenic.

I'd recommend you to upgrade to at least 2.2.x, the scalability of
2.0.x means there is really no good reason to spend time porting GigE
drivers to it.

I am upgrading to 2.2.x, but mean while I need e1000 driver to run on 2.0.x,
I'm sure that others might need it too.

Some more info:
I compiled it with support for IANS and without, but I get the same outcome,
only setting E1000_IMS_RXSEQ will cause endless interrupts that cannot be
stopped not with int_disable and not with cli(), so I guess there must be a
bug somewhere, so I activated it on 2.2.x and surprisingly it works ok.

Another thing is that without E1000_IMS_RXSEQ, I can see that the interrupt
handler is being evoked, but the driver does not try to receive or send
although I try pinging in and out of my machine.

RE: Intel-e1000 for Linux 2.0.36-pre14

[Ofer Fryman]

I finally managed to get the interrupt handler running successfully. The
problem was, if you run the driver in debug mode, the interrupt handler goes
crazy, this also happened to me on 2.2.x.

Now the driver appears to be running successfully, but I still cannot pass
traffic through, any clue of where to start looking?.

Finally e1000 works on linux2.0.x kernel. If only I had the specs a couple
of days ago...

RE: Intel-e1000 for Linux 2.0.36-pre14

[Ofer Fryman]

I meant that if I had the specs I would have finished the driver sooner,
unfortunately I do not have them, but I am eager to get them in order to
improve performance on the card.

You are right there are no specs on Intel's web site, nor did anyone in
Intel answered any of my e-mails or returned any of my calls.

Heh! 


Well- at least you have it working! Good!
