Simplemail opening large files and viewing pictures is slow, even on and 060 with a radeon 9200.

I'm not a big gamer anymore, but looking for more day to day snap in using my 3000...

Thanks for the help!

Hedeon has not gotten the WarpDTs working yet, so we really don't know. One guess is that if Simplemail uses datatypes that this could be sped up greatly, but on the other hand if it's a 68k app loading PPC code in a 68k window it could end up being not so fast. The ghost of context switching strikes again or not maybe. We'll find out when we have the DTs working to test with.

Sometimes I wonder while testing this if it wouldn't be simpler to just run the whole OS in PPC, as in OS4 or IFusion or something.

Much simpler but then as in the case of os4 Classic the Amiga just becomes a keyboard really may as well run it on no. Classic hardware

.

It's not "simpler" in case of Sonnet and Mediator, because there's no way for PPC CPU to access Amiga address space. At least we didn't figure by now how to do it.

Hedeon · 11 February 2016, 10:23

The problem with WarpDT (and with OS components like libs, devs in general) is that the OS loads them automatically in FAST ram. Even with marking all the hunks to be loaded in PPC ram (which happens) the lib base, dev base etc and function tables are set-up in FAST.

Now, the PPC can still access the base/function tables of libs/devs using context-switches. This makes it all very slow. (Warp3d libs access: gears goes from 75FPS to 25FPS or so).

So I let the initialization program pre-load these libs with a temporary patched ramlb to also force the base/function table into PPC ram. (is there a way to tell ramlib to set up a library/device in any memory you want?). Patch is removed after initialization.

I'm not sure how datatypes are handled, and haven't really looked at it yet, but I suspect in a similar way (base/functiontable?) So I don't know yet how to pre-load them.

I did notice that WarpDT also opens warp.library. Not sure why. Warp.library is undocumented. Maybe it's just a version check.

Datatypes (WarpDT-suite) are still high on the to-do list as my original goals were MP3, datatypes and dnetc. I got side-tracked by getting games/warp3d/stormmesa etc. to work.

Same difference as running a Cyberstorm PPC with a Picasso IV, Zorro sound card and a Deneb with a USB keyboard, in that case it's not even a keyboard dongle. You can always reboot to get back to OS3.9, that's not something you can do with any non-classic machine.

I've been running the Sonnet for a little over a month now and it still amazes me how well it works, when it works

Regarding jpg decoding on the sonnet, I tried ppcjpeg on a 3264x2448 jpeg about 5MB in size, this is just a simple jpeg picture viewer.
On the 060-66MHz using Multiview with ak-dt ~48 seconds
On the Sonnet somewhere around ~2 seconds I can't really operate the stopwatch fast enough to be accurate here.
Not really a fair comparison since it's not a datatype to datatype comparison, but maybe we can hope for the same sort of performance with a PPC datatype.

Well we got UAEWOS running on the Sonnet, you might be wondering a few things:

1) Isn't that slow?

2) Isn't that pointless?

3) Is there anything gained by doing that?

The answer to all of these questions is "Maybe"
I give you a screenshot:

Hedeon · 28 February 2016, 22:43

Did you just pick the test which gave the best results? tsk tsk :-P

grelbfarlk · 28 February 2016, 22:51

Of course, that is the standard nowadays.

Also I have heard tales from the far reaches of the internets that there was a newer version of UAE Wos 8.12.0, namely RC2. I have been unable even to find a site that had it linked at some point. If anyone has this version please zone it.

amigoun · 28 February 2016, 23:20

Would be great if NetSurf is ported to WOS to enjoy comformable browsing on Sonnet.

grelbfarlk · 29 February 2016, 01:01

Yes, I'd be curious to see Bochs or DOSbox on WOS too.

Oh you! Don't be mean to Apollo Core people!

All things aside, having UAE running on Sonnet is kinda cool. Not terribly useful, but cool.

grelbfarlk · 29 February 2016, 01:30

The who people? People running ACT Apollo cards? Wasn't there something, something about some guy that had the code for the Mach chips but didn't want to sell it at any price, something?
At any rate, I played quite a bit of James Pond 2, the scanline mode is really pretty neat it makes old games look a bit like they are supposed to.

Locutus · 29 February 2016, 15:48

Holy crap, that is such a convoluted way to play Amiga games on a Amiga....i'm in shock.

No, Apollo Core. The HDL recreation of the 680x0 processor using an FPGA

grelbfarlk · 01 March 2016, 01:42

Convoluted-yes, also hilarious. Oh and I noticed that 8-bit doesn't render the copper backgrounds properly so you have to use 16-bit.

jack-3d · 04 March 2016, 13:37

I become so excited in the Sonnet project you are doing and today me and my friend joined the Sonnet club ;o)

I would have first question, Should be the Master jumper for SharkPPC activated? Or how do you have all jumpers set? (I will use it with Voodoo4 4500)

strim · 04 March 2016, 18:54

You set Mediator jumpers as for normal operation (slave). The only special thing needed is patched pci.library (pm Hedeon).

Btw. Voodoo 4 is not supported. but it should be trivial to fix.

grelbfarlk · 04 March 2016, 22:43

Also set winsize to 512.
