Re: Sparcstation20 (32 bit) user needs good /etc/apt/sources.list

2007-07-23 Thread Chris Andrew

I can't get the /etc/apt/sources.list at the moment, but the file was
generated using option 1 in dselect (repo set-up).  Can anyway post a good
sources.list for sparc (32)?

Thanks,

Chris.

 Ludovic,

 Thank you for your reply. As mentioned, I did a dist-upgrade from
Sarge.  I
 can confirm that I am now running Debian 4.0 (Etch). Unfortunately, when
I
 try to check for updates, I have problems with the following packages:

 apt
 apt-utils
 aptitude

 The problem I have with all three is that I get an error message that
says
 a public key is not available, therefore the packages can't be
 identified.

That should not happen with official packages after you've run aptitude
(or apt-get) update.

 i am asked whether I should install anyway, to which I answer
 yes.  I get script errors when these packages try to configure, and
a
 complaint that apt-utils is not installed prevents me from configuing
 many
 packages.

That's not an error, AFAIK.


 I am unable to do a straight install from CD of Etch, because I am
told
 that the ESP module that supports my CDROM, is broken, and it is not
fixed
 until 2.6.22, which Debian isn't using, yet.

 In summary, I need to work out how to overcome the key problem.  It
has
 been suggested that I upgrade my debian-archive-keyring (I think), but
I
 am told this is the newest version, already.

 I would appreciate any help.

It'd help if you said exactly which error messages you get, and what
your sources.list looks like.  Any unofficial sources there would cause
that warning about a missing key.

Cheers,
Julien

Sparc32 systems and power consumption

2007-07-23 Thread Bruce O'Neel
Hi,

I have both a collection of sparc32 systems (2x SS20s, 2x SS5/170s, 1x SS4) and 
a very strong interest in low power in systems that run 24/7.

As a result I've done some power measurements on them in order to find the 
lowest 
power system that will do what I need.

(All of the below should have In my experience/with my measurements/etc stuck
in front).

I don't see any important power consumption difference whether the systems
are idle or not. I actually see a decrease when I use a new fast scsi disk
vs the old 1 and 2 gig disks these came with from Sun.  In all cases they
are maxed out in memory as well so that draws some extra.  Finally, this is at 
220V so the power supplies might be more or less efficient at 110V.  In some
cases I've used the SS4 50 watt power supplies and in other cases I've used
the SS20 150watt power supplies and I don't see much difference in consumption
between these two power supplies in terms of efficiency.  My guess is that 
these power supplies aren't so efficient in converting power.

From lowest to highest, measurements taken at the power plug.
 
SS4/110 60watts
SS5/170 65watts
SS20/Dual 100 hypersparc75watts
SS20/180 Hypersparc 77watts
SS20/Dual 55 hypersparc 80watts
SS20/60 Supersparc  80watts
SS20/85 SuperSparcII80watts
SS20/133 hypersparc 85watts
SS20/200 hypersparc 90watts
SS20/Dual 90 hypersparc 90watts
SS20/Dual 142 hypersparc   115watts

For the benchmark I was running when doing this test, to round numbers,
the speed scaled with the clock speed.  

In general these systems were running NetBSD, but, Debian Sarge
was used on the SS4 and the SS20s with SuperSparcs as well with 
no major changes in power usage.

Just a few other numbers with newer systems:

300mhz Ultra10 90watts
Mac 7300/200  100watts (two disks though)
Dual 400mhz Ultra2180watts (two disks though)

I am a big SPARC/PPC fan and not a big x86 fan, therefore I was quite 
disapointed to find a cheap Dell 500mhz PIII drawing only 55 watts or so.  
So, 2x faster than the Ultra 10 and 1/2 the power (round numbers).


As someone else pointed out though, a NSLU2 is very very low power
(my watt meter doesn't measure it).  It's even lower power than some
cheap 8 port Netgear switch (at 11 watts). The house server is a 
NSLU2 because of that.

cheers

bruce

 The problem is, and that has been mentioned before, that *there is no 
 upstream maintainer* for sparc32. Unless some people step up and ensure 
 that upstream issues _are_ fixed in a timely manner, sparc32 is 
 effectively dead.
 
OK, not being a SPARC expert myself, I'd still like to see a list of
issues or bugs which are worth dropping a whole sub-architecture.

Maybe some of them don't even require a SPARC guru to fix them? Maybe
some are easy enough so someone could fix them after reading some
documentation? In that case I'm willing to have a look at them.


  This starts to sound like m68k part 2.
 
 No, it is completely different as m68k _does_ have a group of enthusiastic 
 people behind it who actually work on upstream issues. sparc32 has none.

Well, I just saw three or more sparc32 patches being committed to Linus'
git tree today or yesterday, so that may not be quite correct.

I have measured about 850mA on the 5V side for an NSLU 2 @ 266MHz with a
4GB USB flash disk using the internal Ethernet controller.

That's a bit more than 4W, so that's mean about 5/6W on the 230VAC side.

You are missing the point. Those patches were created by enthusiastic
users fixing the problems that they have experienced.

Until someone volunteers to become the official maintainer Sparc32
is effectively dead. An official maintainer is essential as the point of
contact and the person who contantly tests to ensure that changes
elsewhere in the kernel have not caused regressions.

Without an official maintainer who is going to be responsible for
saying that the port is or is not ready for the next kernel release ?.
The Sun4d subset of Sparc32 is an example of cumulative bitrot
over many years which will take a major effort to resolve.

Interesting!

 SS20/Dual 90 hypersparc 90watts
 SS20/Dual 142 hypersparc   115watts

These are all ROSS RT62[56] modules, right?

Can you tell us which version of NetBSD successfully runs with these
configurations, especially the SMP ones?  Does the latest NetBSD support
some of these configurations?

I vaguely remember reading reports saying that roughly no current OS
(including Solaris) is able to handle them correctly, especially in SMP
mode, so that would be an improvement.

Thanks,

You can start by setting up your own private infrastructure for a new
sparc32 architecture, pointing a couple of buildds at it, and note what
breaks.

You will need to patch gcc and glibc for your new architecture, as you
will need to build for sparcv7 or sparcv8, and we are switching to build
for sparcv8plus, as we are targetting ultrasparcs only.  Once you have
your unofficial port established, it shouldn't be difficult to get
sparc32 support into the official packages.

Then you can do whatever needs to be done with the kernel.  It would be
nice to have things working on all sun4c, d, and m machines.

Hope this helps.

Regardless of the set of bugs or the difficulty of fixing them, every

Debian release policy.

I'm not saying that sparc32 can't meet policy; I'm merely saying that
such a judgement is unaffected by discussions about the tractability
of the existing bugs.

The kernel is but one program in Debian.
