apologies for not being there. I tried but couldent. Somehow, people
here in spain think that chats are evil and I couldn´t convince them to
let me use it. I´m now back in town, so I hope there´ll be no problem to
join the next one.

[9fans] rdbfs

2005-08-24 Thread Brantley Coile
I'm having trouble getting rdbfs to work.  I start the rdbfs as follows:

term% rdbfs -p 1000 /mnt/consoles/bertha

(I've imported the console to bertha from the console server.)

I then run db 

db -k /386/9satabwctst 1000

which sends the following out the serial line

R0030 4c ca 00 80
R0038 a0 58 10 80
R801058a0 83 c4 08 c3
R801058a1 c4 08 c3 83
cpu0: registers for genrandom 2
FLAGS=10086 TRAP=E ECODE=0 PC=80105855 SS=58A2 USP=80200DE5
  AX 080058A2  BX 8021554C  CX 080058A2  DX 
  SI 080058A2  DI 0010  BP 0010
  CS 0010  DS 0008  ES 0008  FS 001B  GS 001B
  CR0 80010039 CR2 080058a2 CR3 2000 CR4 00d0
  MCA  MCT 
  ur 8000c938 up 8022e9c0

As you can see, I get a trap when trying to access 080058a2?  I'm puzzled by 
the 0800
instead of 8010.

What am I doing wrong?

It doesn't look like the kernel is managing to read the
serial input correctly.  Maybe it's coming in too fast?

 could it be that some other process is stealing bytes
 out of the uart?  how do i make sure that's not happening?

that's really unlikely given that the kernel is splhi
looping to poll the uart.

I don't think another process is stealing bytes but I do sympathize
with anybody having uart problems.  I couldn't read all the bytes
off a GPS when it's baud rate was set higher than 4800.

2005-08-24 Thread Russ Cox
 i seem to have it working somewhat now.  i'm just not sure how much i
 can do with it.  it doesn't seem to have a stack to backtrace.  does
 anyone use this rdb?

i used to use it all the time.  i expect it should still work.
perhaps you're not invoking acid with -k?

A while back there was a bug where hardware flow control wasn't turned
on, so characters would get dropped.  Is that in good working order now?

 I don't think you can run xen inside Windows. Xen is always in control of

I've been wondering if the techniques that colinux uses to run Linux
inside windows could also be used to make Xen in Windows possible.

However, I have no real details about what exactly those techniques are,
so this is pure speculation!

I'm sure you could take the xen dom0-domU interface and use
it to allow domU's to be run on top of win32 (or the NT kernel, or
any other kernel, for that matter).  If you didn't want to interpret
the cpu instructions you would need a little hook in the native kernel
to catch trap instructions and handle page faults.  If you wanted to
emulate the cpu (ie. bochs/flex86/qemu) you could directly provide
a xen machine.  Definitely not a trivial undertaking, though.
