Re: Fixes for Tyan s2880

[YhLu]

Eric,

I have made two changes in raminit.c
1. csbase counting
2. fill_last to make sure kernel to scan NUMA successfully.

For s2880 it can work with 4*1G+2*256M RAM, and doesn't work with
4*1G+2*512M or 4*1G+2*1G.

I would try to substitute raminit.c with hardcode one to test for 6G, if it
can help.

Please advise.

Regards

Yinghai Lu

Hi,

does the Solo need any special init for the onboard winbond chip? I
got the solo target to compile again today, but all I get is
reeeaaallyyy slooooow output of the setting up default resources and
node1 before it just hangs.

if so, this is a good time to get the newconfig stuff up for solo.

Stefan, I plan to try the new config commands to get your desired topology 
working. I'll let you know.

Last I checked the Solo has an undocumented PNC chip.  But
it didn't need anything special to initialize the serial port.

Hmm.  Is this perhaps running at 9600 baud.

I believe the speed problem is that the XIP defines have not been
picked up in the new configuration stuff.  Anyway that is where I
would look first for speed problems.

There are enough hard codes in the code at the moment that are smp specifc
that we may have a bug there, that can explain the crash.

Hello from Gregg C Levine
Now you've got my curiosity on active. Whose motherboard, is this? Is
it a Tyan job? Where can I get one?

oh ho. What XIP defines are needed? I'll put them in but can't test until 
monday.

two current motherboards working that you can buy are the Arima HDAMA and 
the Tyan s2880

Nope, don't think so. I have my terminal program running at 115200bps
and i get text through, always some bytes at once, then it lags, then
some more bytes and so on...

This happened with the old config method.

I basically took the hdama code and stripped it down to fit, but i
might very well have missed something.

There has been enough code churn that my head is still spinning in
trying to get in sync with the main tree.

I have updated raminit.c so that it now handles the case of each
memory controller starting from 0 cleanly, and I have updated
cpufixup.c so that we are handling > 4GB of memory properly.  TOP_MEM2
was not getting set to the proper value.

fill_last was pretty much a duplicate of route_dram_access except
different assumptions were made, so I have removed fill_last again.

If you have memory that doesn't get setup properly now holler.

So we should be pretty close.  Before I can go much farther I need a
test for pre rev c0 cpus.  Because a lot of the remaining memory code
needs to be conditional on it.

I am in the last stages of stabilizing an internal version to
be used in large scale testing to search for hardware
incompatibilities.

I also have a the links width and speed being automatically setup
properly.  But the way I discover the links is still kind of
nasty, so I am not quite ready to push the code back yet.

I should be switching over to the new configuration system on Monday
and once that is sorted out quite I can start putting hard codes
where they belong in the board specific configuration.

good timing, I'm back then.

Greg has further ideas and we need to keep talking as we converge. I will 
try hard to get the cpu stuff in before monday.

Note that V2 is now supporting PPC and K8. I am going to use the AMD SC520 
for the third architecture test, then it's on to Elan for the fourth.
