@TiredOfLife Quote: Any progress on the new kernel? Sorry for the delay of this. Yes, there is progress, as a matter of fact the update is in testing now and should be available either later this week or early next week. It will not only contain the graphics fix but also a few other fixes, so if you haven't registered your copy of AmigaOS 4.0 yet, it's time to do so

@MamePPCA1
At the point where we released the July update, AmigaInput was in no state to be released. Only the BlizzardPPC/Cyberstorm version got it back again.

@R-TEAM
Well I thought Warzone 2100 was quite a fun game. I like the way that you can combine parts to form new units. I had an (admittedly) brief look at it, but as per usual, I lack the time.
I think it uses physfs for archive access, if that is a problem I have already ported it and can provide it for interested parties. It might still need some work but in essence it works.

@orgin Well, any legalities aside, and pointing out that I do not speak for Hyperion nor represent them: I think that something like that would be useful, especially considering the fact that you could freeze an emulation at any moment and examine it from the outside. From a performance point of view it would most likely be a bit sluggish, but as a development tool I think it would be useful, and in fact, I toyed with the thought a while ago, but the effort would not be worth it at the moment considering that I have enough other things to do

Hope you will come into a good solution for the graphic problem and give support to pci cards (network) also on Mediator Ziv . Thank you and we all wait for the fix.
The Mediator ZIV should be supported already. If it isn't, then let me know, I'll see that I add it, but I was quite sure it was included already. As for supporting PCI cards, if you are looking for supporting faked DMA tricks, no that will never happen. If someone desires to do so, he can write his own driver that uses a locked bitmap in graphics card memory to do this pseudo-DMA, but we will never support anything like that officially.

I thought that there was a method to allocate a block of RAM that was continuous in physical memory, but that this feature wasn't available in the current SDK. Then devices without scatter/gather support wouldn't have a problem. Did I get this wrong? Hans[/quote] Yes, you can use AllocVecTags with the AVT_Contiguous tag item to allocate such a block. Unfortunately we haven't updated the SDK yet.

Under OS4 this behaviour has been changed, whether this is intended or not.
The behavior was never specified. Nothing in the autodocs indicated that you would get a contiguous chunk of memory, only that you would get memory. Quote: But: taken the case that the most popular DMA devices on Amiga Classic won't receive any updates to provide them with a scatter/gather DMA engine (in most cases this can't be done, as resources in the chips are too small), then the small change in memory allocation did KILL all those devices for OS4. Simple as that. There was always the requirement to call CachePreDMA/CachePostDMA for DMA operation, and this could scatter the DMA operation as well. Many drivers don't call it, though, which can be considered a bug. AmigaOS 4 will emulate that call (unfortunately a bug there prevented it from working correctly). Quote: Of course you may still workaround this situation (which was a feature?) by limiting DMA transfers to 4KB, AFAIK this is the smallest memory segment under OS4. Like I said, it's a bug, and it will be cured with the upcoming update. Quote: Of course you may still workaround this situation (which was a feature?) by limiting DMA transfers to 4KB, AFAIK this is the smallest memory segment under OS4. But then you drop performance, as each 4KB block will need its own DMA engine setup, CachePreDMA(), interrupt, CachePostDMA() and all administration stuff correlated to DMA. The 4k is the page size, and the change in the memory system in AmigaOS 4.0 wasn't small, it was the single most massive change in the kernel. And it was all for the better. FWIW, the memory system is at least 10 times faster than it used to be, external fragmentation is down to a minimum. And driver that correctly uses CachePreDMA/CachePostDMA will continue to function. Only those that did not use these functions, in spite of being documented as being required, will cease to work. Quote: And yes, I consider this particular detail in OS4 as broken. Well I consider drivers that don't play by the autodoc rules as broken. If a driver does not call CachePreDMA/CachePostDMA and cannot cope with the results of the call, then this is a problem of the driver.

You are free to try. We do not recommend this setting, but if it works for you then by all means enable it. However, if you discover some problems/instabilities, you should try with 70 ns first before reporting an issue.

@mboehmer Quote:
(as stated by other people in this thread, DMA and memory allocation is kind of broken in OS4).
Beg your pardon, but that is not true. There is nothing wrong with either DMA nor memory allocation under AmigaOS 4.0. There is a bug in CachePreDMA that will prevent it from working correctly when the DMA transfer is over 4k, which should be fixed in the meantime and will be part of the update to be released later this month. Of course, the memory under OS 4 need not be continous, so scatter/gather DMA support is required from a device, but that is not a bug but rather a feature.

Update on this one:
After I got the new case it turned out that my BlizzardPPC was dying - it would sometimes not initialize at all. I got a replacement two days ago.
The good news is that I've been able to fix the graphics trashing issue. I have also added support for the later Mediator models.
There is apparently another issue with SoundBlaster PCI cards not being set up correctly. Although the drivers don't work because of lack of DMA I intend to fix this since it might affect other cards as well. There is also one other thing that I need to add which.. well... more on that later.
We're putting together a few other things now that should go into a small update, like a fixed RTL 8029 driver. Hopefully this update will then be released later this month.

I don't know xrope, but I have my doubts. You would need to port the TKinter module, and as with most GUI toolkits it pulls in a whole bunch of other dependencies.
I never liked Tk either... Reminds me too much of Motif *shudders*

TKinter does not work on AmigaOS 4.0 (assuming that you do mean the AmigaOS 4 version). It would require TK, which is an X GUI toolkit.

No, I think I understood you. No, there are no plans to revive the WarpUp emulation (PowerUp never was in there anyway). That is why I said the drivers will be native AmigaOS 4 drivers.

On the subject of the graphics corruption fix, I am awaiting my new system to continue the work. Right now, sending kernels to external testers does produce too much "lag", so I rather go back to what I was working on prior to that and await the day when I have my new system up and running so I can work more directly.
This means unfortunately that you all have to wait a bit longer for the Voodoo graphics fix, I'm sorry for that, but there isn't much I can do right now.

Considering there isn't any new SDK yet, I can't really tell. But certainly no MESA support. What kind of OpenGL functionality beyond what MiniGL offers do you need?
