Hey, Hans.. this is quite a cool project. I havent been following it too closely. I didnt realise you had a driver in the works for current machines (using PCI cards). I thought it was for PCI-Express for one day in the future when new machines appeared.
Well, I'd have no hardware to develop this on if I had to have a machine with PCI-Express. Fortunately, a few manufacturers provide PCI cards which have integrated PCI to PCI-Express bridges. Quote: What would the theoretical performance be like in 3d and games compared to existing Sam440ep's, and A1 AGP Radeons? How about Quake3? I'd expect the performance to be better than existing AGP Radeons in general. The texturing speeds should be higher. However, the 2x AGP bus still has an edge when it comes to transferring vertices/texture data so there may be a few tasks in which that gives a slight edge. Typically 3D graphics speed is limited more by rendering complex effects than the bus bandwidth though, so the new cards should generally beat the older generation. Please note that the current Warp3D drivers for the Radeon cards aren't getting the maximum out of these cards; they can do better, but certain issues need to be solved first. What I think is more important is that these new cards have proper GPUs, so fragment/vertex shaders and OpenGL 2.0/3.0 are a real possibility. Despite all the work that I've done on MiniGL, I can't wait until we can ditch it for a full MESA port. This is something that Radeon 7000-9000 cards simply cannot do. Hans

Hello Hans,
and also many big thanx from me for your great efforts!
I understand your suggestion not to buy any GFX cards in advance, but do you have a rough estimation about when you probably will have some testable version of the 2D drivers for the X1300 or X1550 available?
Ciao
I really don't want to give an estimate since it relies on too many variables. Right now I'm still waiting for my computer to arrive in New Zealand. I sincerely hope that it will arrive in one piece and still be working. If it isn't working on arrival then things will be delayed until I can afford a new machine. Assuming that it arrives soon, I'm guessing that it will still take several months at least before I have something that I think is good enough to let others test. That, of course, depends on how much time I can spend on it. Hans

That's fine with me then. 
Any recommendations then what card to get?
Or will any card help?
Rudolph
I'm trying not to encourage people to go out and buy one already since they can't use them yet. However, right now I only have complete documentation for the R5xx series cards, not the R6xx. Therefore 2D acceleration will come first for the Radeon X1300 and X1550. The RadeonHD 2400 pro will have to wait until AMD releases the docs and/or example code. Hans

Any idea when and under what conditions you will share your work with us?
I am only waiting for the Sam440ep-flex to be on sale and will need a gfx-card for it.
And before that I could use that card in my A1.
To be honest, I haven't quite decided how and when I'll release copies into the wild. Most likely I'll have OS4 beta testers test it first before a wider release. I would personally prefer to have hardware accelerated 2D working before handing out an alpha copy for others to try. For now, I can't give any release dates. I can say that there is an issue with UBoot's initialization of these cards (due to the PCI-PCI bridge) that needs to be dealt with first before these cards can be used. Hans

I missed this post. Basically, I'm waiting for my hardware to be shipped to me in New Zealand (just moved back home from Canada), so I can't do anything until it arrives. BTW, people can check up on progress by looking at the RadeonHD development log on my website. It also has an RSS feed for those that use them. Hans

Hi @Hans
Right now, no-one's written a VESA driver for OS4 (at least there isn't one released yet). If someone wrote such a driver, there wouldn't be an issue. IIRC, this is what Scitech's SNAP driver was supposed to do.
I was curious about what happened when I switched from AGP to PCI. I removed the 7000 AGP card and installed the 9250 PCI and booted-up without any other changes. I guess the Radeon driver in Kickstart recognized the Radeon new card and made the switch. The screenmodes in the Devs/Monitor were automatically changed to 9250. So, why is there a AGP/PCI option in UBoot?
If you have two graphics cards plugged in, it switches which one UBoot is displayed on (i.e., which graphics card is first in the list). Hans

Consider please:
- speed of graphic card development?
It's pretty full steam ahead, so sooner or later Radeon 9xxx cards are going to become harder to find. Quote: - speed of the Amiga games/programs development which require shaders? The speed of development will be zero if shaders aren't supported at all. Quote:
- tomorrow there will be new graphic card slot etc. but don't forget the newest "AmigaOS ready" hardware have... PCI from 1993.
I have a Radeon 2400 pro PCI card in my Amigaone, so it is possible to stick one of these in an existing Amiga. Quote: - speed of development of ANY thing for AmigaOS? Which, IMHO, makes it worth trying to skip some of the inbetween developments, and go straight for the latest stuff. Quote:
Tell me what I can do with drivers for AmigaOS4.x which support shaders?
If you're a software developer, write games/demos that take advantage of this new feature. We could then port Torque Game Engine Advanced, and/or C4-Engine which will be instrumental in people writing/porting games to the Amiga. I should point out that no-one has stopped developing the R1xxx to R3xx drivers just because I started working on a R5xx+ one. That is continuing. The OS4 dev. team will continue to improve them. However, there is no point in me helping them out; that would only slow things down. Hans

The best way to speed up the copy procedure is making sure both drives are using UDMA and enabling delayed flushing on the destination partition if it's using FFS2.
... or, not use FFS2 at all. SFS and JXFS are much faster. Hans

I don't know much about DMA.
The benefits apear to be speed but what are the negatives?
I assume there is a reason it not set as default?
If you are talking about the Amigaone XE version, there is a known bug on the motherboard that causes trouble with DMA and the on-board IDE ports. There is a hardware fix for this, but most people don't have that. Thus, it's disabled by default for safety. Using a PCI IDE card bypasses this issue. Personally I think that it should be enabled on PCI IDE controllers by default, and only disabled with the on-board VIA controller. For the SAM 440ep motherboard, I'd expect that DMA is enabled by default. If it isn't then this is something that should be changed, IMHO. Hans

I install windows XP when I need to :) like I said via true image ghost.
I can get my system up in 5 mins for a 20 GB ghost Image.
10 mins if I want to validate.
I guess you havent used imaging software.
I have used Acronis True image, but, when I needed to restore from a backup, it failed. It seems that it cannot handle backup files over 3GB via a network connection (the backup was on a Linkstation). Needless to say, I was not happy. What's the point in having a backup if it fails to restore? To answer your original question, imaging software is for restoring from a backup, not installing a new system. The installer is supposed to handle whatever hardware and configuration that the user has/wants; a disk image is for only one hardware/software configuration. I don't recall my installation of 4.1 taking that long. Hans

@Atheist
Just to be clear, a hardware design in an FPGA is not software. An FPGA may be reprogrammable, but you're reprogramming the connections between logic gates, not running a sequence of instructions.
Regarding implementing the Artica-S chip in an FPGA, that would be a huge task. You'd basically be designing a new Artica-S chip (minus the silicon layout level stuff since you'll be implementing it on an FPGA). The only way that things could be sped up if someone somehow stumbled upon MAI Logic's own design files and to use those to synthesize FPGA bitstreams.

Ok one point about error messages when using templates (hint in case you want to participate in such contest for the longest, try to use VC++ 6 it is really a mess 
VC++ 6 is old and non-standards compliant; it doesn't even do variable scoping correctly. People should upgrade to the latest Visual Studio. Back when I used it, I had to deliberately code things incorrectly in order to get it to compile. When I switched to VC++ 2003 express, I had to go through and fix everything. One thing with GCC that is a minor annoyance is that you need to set a compiler flag in order to get it to use the latest C standard (which includes C++ style variable scoping rules). Hans

I guess the port should be divided in smaller parts like wxBase (IIRC and if the code did not changed too much since then this part "only" need merging with latest code version).
Then it would be a good idea to find relatively small application that only depends on few (2 or 3 max) wxWidget subsets and create a bounty to port those parts. Check would be that the considered application should compile and work.
The more time will be passing the more parts would already be ported so check applications would be able to be a bit bigger too (because even if dependencies are big, only a few of them remains to port)...
IIRC, wxWidgets has a test-suite that could be used to confirm whether various components work. WxBase had the file access stuff mostly done. I made a few fixes foe the OS4 version, but it should be changed to use 64-bit disk I/O. However, wxWidgets supports unicode in some shape or form, and I don't think that anything was done in that area (kind of hard when the OS' own unicode support isn't up to scratch). Hans

That sounds good. Please note that the wxWidgets-aos project on sourceforge is targeted at all Amiga OS variants, and the intention is to keep it that way. Also, distributing the bounties to all contributors may be a bit of a challenge since this project will likely require several people to work on it.

Well, it's outdated again in the meantime probably so it wouldn't be of great use anyway, but if you want i will note it down to my todo-list and have a look again on that code, update it to the latest wxWidgets and send it to you. But be warned: it will take some time until i can spend some time on it again. AND: I probably won't contribute to the project itself anything.. at least not in the foreseeable future (i.e. implementing the AOS backend).
That would be great. Hans

One good thing about wxWidgets is that it would allow Amiga developers to reach a larger target audience.
This is exactly why I want a wxWdigets port, and why I'll be using wxWidgets when I write a new app. This is also why I signed up to the wxWdigets-aos project on sourceforge. Unfortunately, I need someone else to update to the latest wxWidgets version and get things moving. I'm not good at porting stuff, and my knowledge of wxWigdets and the Amiga OS GUI system is limited. We need a team of several people to make this happen. Hans

@Fab Quote:
With C++, you don't really have a well-defined standard, unfortunately. As a consequence, each compiler interprets C++ as it likes. And even between gcc versions, you can get incompatibilites/weirdness. Let's not even talk about binary compatibily between libs compiled for a version linked to a project compiled for another version.
The language standard is pretty well defined. What's missing is a standard for the ABI. Basically, it's up to the compiler to decide how classes/objects are implemented. This appears to be true of pretty much any OOP language. If there were a standard ABI then it would be possible to pass OOP objects to shared libraries without worrying which compiler it came from. Quote:
Even about readability (which can be helpful for a port :)), it can sometimes be harder to follow. Things like references, inheritance and templates can make it harder to follow codepath (of course it's doable, but it just takes more time). All this heavily depends on projects of course.
A lot of this has to do with poor coding style. I've seen some really unreadable code in C as well. Granted, C++ is harder to come to grips with (being a superset of C, it's not surprising), but it is very powerful. I wouldn't write a huge app. in C because OOP really helps dealing with large complex systems. Hans
