[MTL] picked up a fistful of blank 27C256 EPROMs from [DAV] today. We
successfully read the snack machine original and burnt a duplicate which
the snack machine happily ran on.

Next up:
 * networking the DOS PC with the EPROM burner;
 * assembling a replacement ROM;
 * running serial cables to the snack machine for testing - the
   "printer" port and the possibly dead coin mechanism.

Nick.

It's arrived! It's got a basic Debian install and is sitting in the
rack under hydra. Possible fiddling with VLANs tomorrow, in conjunction
with olive, the Cisco 2924XL and later bertoli, the 2912? .

When will the next bunch of work be done on the snack machine?  Is there
any stuff I can do towards the ROM image in the meantime?

The new ROM image needs to be modified to use the inbuilt serial
port to chat (instead of the hypothetical 16550 that it's been
taught to use).

Code is in CVS.

My exams finish in about 2 weeks, so I'll be back on it then.

Damn, those schematics are huge.  What is the part number of the IC (main
processor?) with the serial port in it?

How did the VLAN stuff go?  Roughly what can those two Cisco devices do?
Are they routers, swiches, fibre mulitplexers or something completely
different?

Switches. IIRC bertoli only does ISL (Cisco proprietary FLAN stuff), not
802.1q or whatever. Could be wrong, someone'll correct me if I am.

Yeah, that's right. Stuff mostly works again now, the main problem I had
was olive (the 2924) not liking the uplink unless it was in trunked mode
(which the uplink isn't at the moment), and then trying to deconfigure the
accelar gracefully. So the uplink now goes to eth1 (the e100), eth0
(e1000) goes to olive with vlans 2 and 3 being machineroom and clubroom
respectively. bertoli needs to be connected up and taught about vlans.
Magic IPs, loft vlan etc still need to be set up, but tftpd and mop work.
Appletalk requires a recompile of the kernel. meito and other things on
the cisco now have working waix again.

I apologise for not compiling in AppleTalk, I didn't actually remember
it. You should just be able to compile 2.6.6 using the current config
and appropriate extra bits.
If you get bored, add the IPX modules as well, in case we feel like
adding IPX routing at some point (*evil smirk*).

They are Catalyst switches, support 10/100 ethernet.
One is a Catalyst 2900 series (Grahame says it is infact not a 2912). It
can speak ISL vlans. The other is a Catalyst 2924XL it speaks 802.1Q and
ISL. I _think_ it can map between the two, allowing us to run a .1Q
trunk into the router from the 2924 and have it fed as an ISL trunk to
the 2900.

AFAIK they both run IOS (rather then CatOS) although I don't know what
version.

Ideally at some point, we want to get another Catalyst, probably a 2950
with GigE module that we can connect to the router over a gig trunk.
Then run bonded 200 (or whatever) trunks to the other two switches. But
that is something for the future.

It's some breed of HC12. I don't remember off hand. It's on the
schematics though which are about somewhere (possibly in the
machine?)

2.4.26 patch: http://dagobah.ucc.asn.au/fpu-bugfix-2.4.26.diff

It's a port of Andi Kleen's 2.6 patch, which he says doesn't catch
all cases, but it's the best thing yet.

I was having a quick gawk at the machines. They are running 2.4.24-grsec
with random things turned on that shouldn't be. I'm sure this can't help
us much. The UniSFA machine is running 2.6.3 and seems to be a lot more
stable. At some point I will build them a copy of 2.6.6 (without crack
like grsec). We'll see how that goes.

I was goign to suggest this, it seems like a good idea because it will mean shit-fast access to the drives from the main user machine, and be cheaper.

Grahame doesn't have one. Grahame's mother has one running Windows, runs
fantastically apparently.

This was done last night. While I can't yet make many comments:
[davyd@pitch davyd]$ uname -a
Linux pitch 2.6.6-thinclient #1 Tue Jun 15 15:36:52 WST 2004 i686
GNU/Linux
[davyd@pitch davyd]$ uptime
 11:21:07 up 15:15,  1 user,  load average: 0.02, 0.04, 0.08

If someone modprobes i2c-proc on them, we should be able to get sensor
readings. Perhaps we should consider setting up mtrg for them, graphing
sensors readings and uptimes. Just for interests sake.

While 2.6 seems to give overall better performance, we might notice a
drop in frame rate in GL applications. The latest round of nVidia
drivers don't seem to perform as well as some of their predecessors.

It was already setup (i2c-proc doesnt exist in 2.6 though).
sensors was installed in /usr/local/bin, taking priority in the path
and that version didn't look in /sys.

pitch:
M/B Temp:    +40 C  (high =  +105 C, hyst =    +0 C)          (beep)
CPU Temp:  +48.0 C  (high =  +127 C, hyst =  +127 C)          (beep)
velvet:

CPU Temp:  +47.5 C  (high =  +127 C, hyst =  +127 C)          (beep)

That's not hot.

They also do bad things(tm) wrt interrupt handlers (see dmesg).

Can someone remove the /usr/local version then at some point?

That's really quite mild for an athlon. To be empirical we should trial
them during games of Enemy Territory, we'll see how things go.

Interesting. It's the same driver I'm running, but I am not getting
nasty going on. Even though the machine has APIC turned off, we are
nowhere near running out of interrupts.
[davyd@pitch davyd]$ cat /proc/interrupts
           CPU0
  0:   57925629          XT-PIC  timer
  1:      36745          XT-PIC  i8042
  2:          0          XT-PIC  cascade
  9:          0          XT-PIC  acpi
 11:    4603365          XT-PIC  NVidia nForce, nvidia
 15:    8356849          XT-PIC  eth0, ohci_hcd, ohci_hcd

I guess this is a cute side-effect of not having any disks in there.

It would be nice to get some mrtg style monitoring on the machines.
Perhaps we can look at that later on in the week.

I've chmodded it -x for now. If we ever go back to a 2.4 kernel then
we'll probably need it again. (Is that why it was there?)

The badness is coming from the fact that the nVidia drivers are
calling functions from within interrupts that they're not supposed
to. I don't see how running out of interrupts or being diskless
correspond to this, but then again, I can't explain why we
pitch/velvet them and you don't :) They don't seem to be harmful yet
anyway.

6 days and I can get something going.

Message-ID: <20040616133725.GD4647@blackham.com.au>

mtearle and I tried burning my new version of the ROM tonight, and
about 7 tries later, we can get it to beep! I moved the beeping code
into the on-boot assembly instead of the C code. I have a suspicion
that the reason it doesn't do much else, is that I can't setup the
stack correctly. I've never had much success in programs that set up
or move the stack reliably.

If anybody wants to checkout the code from CVS and look if I'm doing
anything silly? - reset vector (in vectors.s) goes to _start. _start
does some fiddling of registers, sets up the stack by:
    lds _stack
where _stack is declared in memory.x to be 0x007f - 1 (copied from
another project).

Should this be all that's needed to tell jsr where to put it's
return addresses?

I'll look into it more after exams in 5 days, but if anybody feels
bored in the meantime, there's a starting point.

The next thing I'd like to get working is writing to the display -
this should make debugging *much* easier.

S'all for now.

If it helps, I have a HC12 simulator which seems to work ok. I'm not
sure if it's the one Packrat likes or not, but you should be able to see
what's happening in the memory map.

Evil gcc optimising the usefulness out of code. Fixed. All keys are
now detected.

The motors now move (= Home sensors need to be used to tell it where
to stop correctly. (Code is there, but not used yet).

Despite this however, there is now a fairly functional ROM in the
machine that will drop stuff out. Note the contents of the machine
is a couple of months out of code. :)

So all that's left is the home sensors, a serial keypad and the rest
is icing!

Jamie Moir mentioned that he can get SuperMicro cases. They're not dirt
cheap, but they're compact and they have real hot swappable HDD trays.
They come alone and in combos with motherboards. The prices below,
including GST, are for the bare bones system - no drives at all.  The
more expensive ones come with a motherboard.

SC813T-500:	$890

Two drives, P4 motherboard

P4 motherboard with dual gigabit onboard and 64-bit PCI-X!

6013P-T:	$1735

Dual Xeon board, cheaper than Dell! (Then again, what prices are UCS
getting on Dells?)

Most vendors it seems a dual Xeon is worth just under $10k with 4Gb of
RAM and five 130Gb SCSI disks. Dell are in that range.. we're getting a
single 3.2Ghz P4 and 2Gb of RAM + 2 * 80Gb SATA disks for about $2.5k.
Those sort of machines are being used for the webmail.

The Dell Xeons come with excessive numbers of blue LEDs, nice management
that mostly can be used from within Linux, a decent hardware RAID
controller, hotswap SCSI, fans, PSUs...

Mailman started playing up around 12:30 today due to some stale lock
files. It should be working again now, but if any emails were sent
to ucc lists that never made it, you will probably need to resend
it.
