Im great fan of todo-lists and this tool exactly fullfills my idea to do simple everyday things with my Amiga.

Still have to say, that for my taste there is too many steps to fullfill simple task, create text. Maybe its just me, but is it possible to shorten task ?.

Other thing, wich is maybe easier to fix, is to get bit more space to text. I tend to make bit longer todo lists to maintain bit longer projects to small memorable parts perhaps with keywords and internet links and so.

Newerthless, good work :)

@Rolar

For my g4 1ghz and 1Gb mem its too much, memory just fills and it is unusable. So when/if Odyssey gets lighter, I can test it. Maybe this is limiting factor to get reports, more generally?

Some sites text parsing is way off, layout allso, but this is probably used chromium version (?).

If someone from dev team pops up and tell what areas to test, people has some idea… Amigaland has been long out of modern browsing so what is considered as bug? As alpha development state, what is wanted real bugs, hangs, grims?

Layout, text parsing and so on, are they under development atm, so is that worth of report?

@MazinKaesar

On hyperion download area hotfix is merged with upd2. So there is upd1, upd2, upd3 avail.

So I would pick upd2 and upd3 from hyperion site and drop hotfix.

Worth of try anyway. And perhaps better to refresh upd1 pkg allso.

Ok, thanks. Im mixed things again it seems.

Looks like 2b2, 2b3 newest OF differ from 2b5, wich works with 2gb. All differs from latest public though.

Hopefully thinking… bboot on real 2b2 probably doesnt change this…

Anyway I think that there may be something on 2b2/2b3 boards itself, wich prevent 2 gb functioning correctly.

@balaton

True, thanks :)

How about peg2 target, didnt dig it more, but memory as 2gb didnt work?

@n3m3

Dbl post again…

@n3m3

I digged some information to clear my head and made list for myself. It can have some errors but still some clarity what is what.

SM502
Datapath

Application -> AmigaOS -> SM502 driver -> QEMU device GTK/GL blit -> host GPU


Highest emulation overhead
Good compatibility, works everywhere



PCIe passtrough, IOMMU, Amiga native driver (Radeon HD/RX)

Datapath

Application -> AmigaOS -> HD/RX driver -> IOMMU -> host GPU

- Least emulation
-Good performance, near real thing probably, what other parts emulation cut down then.
-Cant do anything with graphics.library on-demand behaviour, short memory blocks from cpu -> gpu. Same as on real machine, though.


virtio-gpu

2D
Application -> AmigaOS -> virtio-gpu driver -> virtqueues -> QEMU virtio-gpu -> host GPU -> compositor

3D
Application -> AmigaOS -> virtio-gpu + virgl -> GL/VirGL commands via virtqueues -> virglrenderer -> host GL driver -> host GPU


-batched commands over virtqueue. At least possible that graphics.library chit-chatting with GPU is sended on larger chunks over DMA. Good.
-Emulation overhead higher than PCIe passtrought

Qemu supports OpenGL 4.6 / Linux Vulcan , any mesa on linux is valid for Amiga.

Cant comment Win/OSX as dont know them on that context.

@all

Got just AmigaOne up on qemu. How to set up audio part, as there is some missing parts on real HW?

Thanks.

@balaton

I think that you are right, first partition doesnt need any amiga flags. I dont remember any more, what I did 15 years ago, when I got peg2. My boota has been as is ever since. Ok, bboot&co added, but same disk, same partition scheme. And I probably mixed things when I booted from ide and moved OS to run on SSD. I changed it recently back to boot OS from ide, as it is more clean.

bboot works correctly, it boots, where Im set it, first bootable partition, highest or equal boot priority. Amigaboot.of skips hd:0 as unintresting source to boot and search next valid. Simplified.

@flash

Good, it works.

I digged those out from OF with forth, didnt have time to test, how to set IRQs on more sensible order. Mostly because I didnt find correct way to call chipset (yet). My brains can be allso too small to make universal script, only particular where slots are populated with (my) known devices.

Anyway, as expected (and said), all irqs really are on 0x09 on OF, except ide. It is isa device or treated as one, so it gets own irq there.


For my understantment Pin A-D is hardware routes from slot to chipset. All peg2 slots has A-D wired. If you have multi-device card, say usb2.0, there is three devices, usb 1.0, 1.1, 2.0. Then card will get three pins. Each pin can have different irq number on samre slot (wich goes after all to chipset PIRQ:s). Not all pins necessarily have same irq. Pin A on one slot can have different irq on Pin A on next slot.

These frigging irq:s are pretty alien to Amiga ... :D Doesnt help that peg2 OF is low-level env, where everything is possible but nothing is available easily.

I presume, that modern NG motherboards (pcie) uses MSI/MSI-X scheme, where there is a LOT of irq:s to use and nothing to worry about. If they dont fall back compability layer to old IRQ:s. Anyway PCIe uses MSI/MSI-X nativelly.

I read it from somewhere, dont remember where. At least this edge/level can come from "The Open Desktop Workstation" specs, wich peg2 is build on. All irq on same, dont know. Dont know why level is picked instead of edge, maybe it was just leaved to OS to set them.

Hi,

@flash

On some circumstances I had to set first partition (hd:0) boot priority lower than AmigaOS disk. Both Zero-zero leads bboot try to boot OS from first partition, where bboot resides.

There is still lower/uppercase on upd3 kicklayout. On kicklayout is written SmartFilesystem when file name is SmartFileSystem. Bboot doesnt find it and result is black screen.

Edited: In here ”boot hd:0 bboot.fth” works fine on real peg2. Boot priority hd:0 is -3 and kicklayout/filenamind upper/lovercase corrected. Peg2 2b2, slots populated with sii3114 and nec usb2.0 card.


@Zoltan

As for bboor README: It is also possible to get messages on both console and serial with "Ofs"

How you set OF output to both screen and serial on same time ? I tried ”setenv output-device serial screen” when only first applied. Where serial is devalias to OF real serial device.

Thanks.

@balaton


Thanks.

I expected that driver is general. Still qemu is pretty complicated software and it is sometimes difficult to understand, before see and use.

I even read some article about qemu and Virtio-GPU couple of days ago. Didnt get clear pic, if driver is on emulated machine or plugged to qemu on x64 side. So now I can make safe assumption, that it is Amiga driver, ppc.

No one probably cant say now, what will be emu penalty with single core cpu.

This is good thing indeed.

@n3m3

Sailor's excellent article about 3d. There is good pic how sw-parts are together. Real system with all ells and whistles. Somehow valid without gfx card, some parts drops away.

@Hans

On wich emu-target these drivers will work, is AmigaOne and Pegasos2 included?

doble post, deleted...

Not deep testing but it feels fast and steady. Pegasos2, no random Grims
/bugging any more.

Using it is as Amiga should be, everything flows well, finally. Remarkable better.

Thanks for all involved :)


Missing AmiDVD as many, but most likely it will come back. No other victims atm here.

@HansQuote:

Excellent, thank you :)

@Hans

How these drivers are implemented, does it use any host-supported card or do you need Amiga-supported card ?

Thanks.

@n3m3

I have only some general assumptions and quesswork.

Ryzen 7 8845HS is pretty impressive mobile chip. Compared to ryzen 7 7700 desktop you get 5-15% penalty to raw cpu power.

Memory is 64 bit so-dim, but dual channel. as on desktop you get dual 128bit memory.

At least you should have both memory slots populated with ddr5 5600.

Small form pc has more work to push heat out. Temps up - lower speed.


Not much more to check than memory side on hw.


I probably would check Archlinux. It leaves lot of bloat out as you really need install all yourself. Archlinux + xfce4 is pretty light combination and somehow usable still. Add there firefox and qemu itself.Alltough installation is bit hard as you need to build system from legos. Not too hard as needed pkgs are pretty few after all.

I will make "later" new archlinux inst to my browservice project, I can mark down how to do arch-istallation but not very soon. Cant get it out from memory...

I think that iommu and compatible gfx card is actually safest bet, but out of question with your box or my laptop anyway.

@AmigaOldskooler

I probably would mail to amiga-shop and Amedia about availability to be sure about stock.

I think anyway that OS4.1FE is near sold out.

Probably Hyperion made them available as downloadable then.
