[9fans] Successful install+update?

[9fans] Successful install+update?

[Thomas Miller]

Hello, 

Maybe I successfully updated and recompiled a 
plan9 system which was installed today from an 
install cd burned back in August 2003.  I had to
resolve a couple of minor problems which I will 
mention briefly.  I have some questions too. 

I used the August 2003 install cd to put a kfs 
file system on an x86 box.  I got a sources 
account, and the pulls seemed to work fine.  

My "mk all" in /sys/src didn't complete until
after I removed an empty directory called 
/sys/src/cmd/rtstats.  The rstats directory 
existed on my system, but was not on sources.  

When I installed and rebooted, however, the system
got only as far as "dossrv: serving #s/dos," 
followed repeatedly by "fifo stat 0 scrio d6000000 
scr 802b2028 pc 8017094E" (copied by hand).  

I reinstalled from the cd, repulled, rebuilt, and 
reran "mk install."  After looking around, I 
guessed that the kernel needed to be rebuilt too.  
I rebuilt and reinstalled 9pcdisk, and the machine
now seems to boot and run fine. 

Logs made with "| tee logfilename" are available 
at ftp://insolvencyhelp.org/pub/.  The logs are
for a pull a few days ago, a second pull today 
just prior to today's first build, and the "mk 
all," the "mk install," and the kernel "mk"  
from today's second build.  

I'd be grateful if one of you guys who actually 
know something could please warn me if I wasn't as 
succesful as I think.  Maybe I somehow shot myself 
in the foot in a way I do not yet realize.  

Also, I'd like to know if there was an easy way 
I could have fixed the kernel problem without 
re-installing from the cd.  

Would anybody care to explain why the old kernel
didn't work? 

Thanks to everybody responsible for making plan9 
and for making plan9 available to me.  

Kindest regards, 

Tom

I saw that on some of our machines and I think it has
to do with changes in the nvidia driver that don't fit
well with our cards. Going back to the driver version as of
some days go fixed this.

(IIRC it's /sys/src/cmd/aux/vga/nvidia.c and 
/sys/src/9/pc/devnvidia.c; although I'd also go back to
the /lib/vgadb of the same date just for sanity).

I don't understand why this did fix your problem; although
I'd like to. Maybe I'm wrong regarding the nvidia thing.

vganvidia.c was updated on the 6th (or 7th) of April and the 'fifo
stat...' message disappeared from it:

/n/dump/2004/0415/sys/src/9/pc/vganvidia.c:385,458 c /n/dump/2004/0407/sys/src/9/pc/vganvidia.c:263,264

so your troublesome kernels must be older ones...  i haven't
recompiled since (though i must now, to get geoff's ipv6 changes in)
so i don't know whether my cards will experience any problems with the
changed vganvidia.c...

I see. Actually we had both a cursor/speed problem and the
message. But I now see how the message went away.

thanks
