Hi All,

I just thought I'd post an update. I've compiled the Scherzo and I'm running
the verison I complied. I've been working through the design changes I need
to make. This kernel mode stuff is tricky. But, I thnink I've got a dresign
that will work. It might just take a couple of weeks to get a build out
that we can test.

Things are moving forward.

All the best,

Mike

Mike, it's just amazing to see this. This is every bit as much a
landmark moment for the "post-discontinuation" life of the platform as
porting Scherzo to XP was in the first place.

It raises a bunch of questions - did you decide to take it "object
oriented", or are you concentrating on cleanup? How deep are the design
changes?

And aside from the aesthetics - meaning the "objective good" of
cleaning up dodgy or outdated code - what are your end-goal aims? What
do you hope will be addressed or enabled as far as end users are
concerned?

- Kerry

Hi Kerry,

The Scherzo is a perfect and efficient design as long as you've only got
one cpu. I'm almost certain I've found the multi-cpu bug in the scherzo.
It's complicated, but it relates to the app enabling an interrupt on one
cpu when it needs to be masked by another. When there is only one cpu, the
app can't do this because the Scherzo is running and blocking out the app.
With more than one cpu, the scherzo expects it to be the only thing running,
and the other cpu messes up its operation.

It's really a minor redesign, but it's a big deal for me because I've never
worked in kernel mode before.

I'm going to do it in two stages.

1) move the DPC code into the ISR, which means I will have to use the interrupt
spin lock to guard the various queues.

2) replace the queues with newer designs that will allow for not using the
interrupt spin lock all over the place.

3) (maybe) break up the work of the old DPC and put some of it in a new DPC
to improve system efficiency (this might not be necessary).

It's tricky stuff, but we'll get there.

All the best,

Mike

What exactly is new about it? Will it run better on xp than the current one.
The current one runs fine except when I go to close PARIS it restarts my
computer.

Thanks, it's been a while since I posted here.

Hi Josh,

It sounds like you need the "minimum setup" installer that Chris Thoman released
several years ago. That fixes the crash on exit.

I'm working on it to make it work reliably on multi-cpu computers (like mine!)

All the best,

Mike

Hi Mike,

Any idea where I can get the "minimum setup" installer you're talking about?

Thanks,
Josh
