Does your vanilla 3.1 install have lowlevel.library?

I don't know, I will have to check

edit: yes seems to be present.

abu_the_monkey · 14 August 2022, 22:01

well I managed to get the builds from vasm to work on a vanilla 3.1 install but only by adding 16mb 32bit chip (that's on top of the normal 2mb chip ram) which is odd.

Karlos · 14 August 2022, 22:05

Is it possible something is up with the memory allocation calls? Does this class of memory get allocated using MEMF_CHIP ?

utri007 · 14 August 2022, 22:18

keep up for a good work.

abu_the_monkey · 14 August 2022, 22:27

seems to be trying to load everything into chip mem, but that does not explain why it works on my normal setup which only has the standard 2mb chip mem but is running rtg.

Weird. Are we talking dynamic allocations using explicit calls to AllocVec or load-time allocation of static data chunks?

Karlos · 14 August 2022, 22:41

Obviously for real systems nothing wants to be in chip ram unless it's going to be accessed by the custom HW.

Karlos · 14 August 2022, 22:43

Maybe some system patches on your actual machine are resulting in requests for chip ram to be allocated in Fast. Anyway, I'll try the more recent build in UAE with some of this mysterious 32-bit chip ram...

pipper · 14 August 2022, 23:08

That should not be needed. The dynamic allocations do not request chipmem unless for the sound effects. There are data and bss sections in the executable that should go mostly to fastmem. Do you have tools to inspect the linked executable for its sections? Maybe something is not setup right during linking.

abu_the_monkey · 14 August 2022, 23:17

@pipper

sorry no, I wouldn't know where to start with that sort of stuff. I am almost sure the problem is with the operator i.e. me and something I have done wrong when installing vasm, vlink and the includes/libs etc.

QuikSanz · 14 August 2022, 23:24

Going by the screen shot. Does any real Amiga have 16MB of 32-bit Chip. My A4000T doesn't, It's loaded. That must be it.

@QuikSanz

no, no real amiga has more than 2mb chip ram, but, emulators can have as much as you set it to.

Karlos · 15 August 2022, 00:04

The 32-bit chip memory setting in UAE is confusing. How does it differ from the regular chip memory? It seems I can set them independently. Is it just the addressable range? Traditional chip ram can be set to 8MB (without a sex and free beer jumper emulation) but the 32-bit one goes way higher...

abu_the_monkey · 15 August 2022, 00:15

yeah, not sure why its there (vampire emulation maybe?). it was just a last ditched attempt I tried because of the gurus my builds were giving under 3.1

the main problem is most lightly something I have not set up correctly.

pipper · 15 August 2022, 09:11

I placed a build of the main executable at https://eab.abime.net/zone/hires.zip
Let me know if this works for everybody.

fryguy · 15 August 2022, 10:05

Cool that you're making progress!

slightly OT: did anyone manage to compile the first AB3D?

Karlos · 15 August 2022, 11:48

I was browsing the wall rendering code. There are a lot of signed integer divides going on. If the input ranges to these can be determined, maybe it's faster to have a lookup or partial lookup. Alternatively, an FPU enabled version for 060 might be doable. If the the same divisor is used multiple times (appears to use d2 repeatedly in several places), it could be replaced with a floating point multiply by reciprocal which is probably going to take fewer cycles.

I get an 8000 000A guru on startup with this version.

Karlos · 15 August 2022, 13:06

On a second attempt, 8000 0002. Let me try increasing the chip memory.
