Sonnet 7200 PCI programming - Page 172

Total aside chaps, and probably showing my ignorance of how this all fits together with the OS here, but is AMISSL something that could be compiled to take advantage of a PPC?

If it is very 68K CPU intensive and if the CPU intensive routine is not called a lot (context switch) then sure.

some more cooling tryings. for more stability.
changed 5v fan with 12v because I wanted it musnt eat 5v power from pci.
now gettemp says 39C in 20min. when I play a movie 30min later it says 43c max and not raising.

trying to test builds with more stability.

Nice modding @starship!

If that's the gettemp I wrote for the 750FX bear in mind that the temp function on the chip is highly unreliable. Although it looks like it's saying something sensible for yours!

starship · 13 October 2019, 14:57

only wondered.

trixster · 13 October 2019, 15:29

it works ok?

starship · 13 October 2019, 15:37

Error:No supported vga card detected

then ramlib and reboot.
Already it is little slow, not optimized yet.

Can you post a showconfig and pciinfo?

starship · 13 October 2019, 17:48

of course.
zz9000 is not pci so pciinfo only shows my little pci ethernet card and ppc card.

I haven't heard anyone report the combo working yet, but it looks like you have the Mediator in 512MB mode, take the Winsize jumper off for testing. That plus the 256MB of the ZZtop9k might be a problem? I mean I don't know I'm just guessing.

BULI · 15 October 2019, 08:25

BTW

I tested successful FastATA with Mediator + Ragnarok.
Works fine in PIO3 mode (about 4,5MB/s)

Actually this guy is giving you bad advice, I forgot you have a Ragnarok, that's going to want about 384MB, so setting Winsize to off will only give you 256MB of PCI space so I'm not sure the Ragnarok is going to like that so much.

It doesn't go higher than PIO3?

Indeed.

the ZZ9000 only uses 256MB of zorro Space (the rest of the 1GB is not mapped) and is sitting outside of the expansion.library setup range actually (>$40000000) and is sitting at $10000000 if I understand the ZZ9000 doc correctly.

Actualy does this combo even make sense?

Sonnet type CPU + Zorro RTG?

When both PPC and RTG are on PCI bus they benefit from PCI speed.

But communication Zorro to PCI and back would be slow, isnt it?

Yes. Actually, the PPC cannot reach zorro space directly. Better use the ARM on the card itself.

Also 2D RTG on the Amiga classic is always 68k anyway. Also for the PCI cards.

With Sonnet/Mediator PIO3 is the higher.
I can use PIO4 and PIO5 about 7MB/z on SSD drive wihout startus-sequence (without active Mediator/Sonnet driver).

I guess this is the cost of PIO transfers or being CPU dependent rather than a proper DMA HDD controller.

I'm going to join the club of Mediator owners soon - managed to get a 5V-only Mediator. As such I'll need to modify my Killer M1 (which has sat in storage for months, waiting for this moment!) with a voltage regulator. The pics on the wiki don't clearly show the kind of regulator used since there's a wire in front of the etchings (I can speculate that it's an LM1035?).

Earlier in this thread someone adviced to go with an LT1034 instead, but that was for a Sonnet.

Which one should I go for? Thanks guys

It was just an LM1085 what I could pull off of some scrap board. LT1085 should work fine too, as long as it's also a fixed 3.3V. 3A should be plenty for the K1.

Excellent news, I should have one or two leftover 3.3V LT1085s somewhere. Will report back when my Mediator comes in the post
