I begin new topic because I need new ideas and advices what to do.
I have Radeon Mobility 9000IGP (devID=58351002) with shared memory which is the main problem.
Chipset is RS300 (devID=58311002) integrated into the Radeon.
I have sources of some drivers and can read binaries of any others.
I also have many observations and I want to collect its in one place.

Existing drivers
AGPGart.kext. My own sources so I can change any what I want. Probably it works. Only with one settings I can enter GUI.
ATIRadeon8500.kext. Write DevID into info.plist. Patch internal DevID to work as 4c66 - approximatly the same card. Patch initialization for DISPLAY_ADDRESS because of shared memory. After the patch I can enter GUI with hardware OpenGL.
ATIRadeon8500GA.plugin. I have no sources and don't know it's protocol. How it works?
ATIRadeon8500GLdriver.bundle. It is a library for hardware OpenGL. Same problem - no any information about it.
ATILead.kext. In the driver I can launch any framebuffer and tune Radeon registers. Problem N1 is register F8. What I found. It is SCRATCH register used by BIOS to report to Radeon driver the size of video memory. OpenGL Extension Viewer read the value as OpenGL memory but System profiler shows other value. The register is used also in ATIRadeon8500.kext in procedure set_display_mode_and_vram. BUT. I can enter GUI only when I set F8=3Mb.
Why-y-y-?
The same for users of Radeon 200M
IONDRVSupport and IOGraphicsFamily. I have working sources and can influence on its. But I still not find a link to GA.plugin.

How they works?
0. With default system drivers I have fuzzy screen.
1. Without AGPGart I can enter GUI. All is fast except SCROLL. Any attempt to scroll a text in window lead to system hangs at all.
2. With AGPGart all is slo-o-ow. About 10 seconds on any graphics event. But SCROLL works!
3. With GA.plugin but without GL.bundle I can boot with any AGP settings and always slo-o-ow.
4. Without GA.plugin but with GL.bundle I can boot and all is fast but all OpenGL programs always crashes with log

So
GA.plugin always delays my system in AGP mode and crash SCROLL in PCI mode.
GL.bundle always crashes at one place.

Other users observations.
1. Toadspit with the same chipset but with nVidia graphic card has GL crashes in AGP mode but no problem in PCI. AGP problem?!
2. Radeon200M users (PCIE graphics) can enter GUI with QE supported only with F8=3Mb as mine. And also have 10 seconds delays!!! So it is not AGP problem?!
3. Users of 4c66 that is the same Radeon but with dedicated memory and with Intel chipset report me fuzzy screen with any of my drivers. No good testings.

Other observation of problematic Radeons?
Advices, propositions?

Now I know that GL and GA works independent.

PARTIAL SUCCESS!!!
I rename 9700GL to 8500GL and try it.
Now OpenGL applications is no more crashes and I see spinning things in OpenGL test in XBench!!!

GL crashes approximatly here

In register EBX I found my F8 value! Why Video_Memory_Size used as address?

Hey Slice, would any trial with my Radeon 9250 be useful considering it's a PCI card ?

Can you tell your observation about graphics behaviuor with and witout any drivers?
I know your card and have your ioreg. Can you try RadeonPCI by Dong to get registers dump?
Any information can be useful.

Ok, I'll try ASAP

May be a problem is in IORegistry keys values?
For example
AAPL,vram-memory
this key used by IONDRVSupport to get VRAM address and memsize.
But in Real Mac I see

I never see such values in HackOS

hi there..

i just whant to say that thank you for all of you trying to make the x200 chipset work..!!

shame i dont know much about programming and stuff.. but know that a lot of people will thank you!!!

Best regards.. bruce

Macintosh and Linux are both based off of unix. Linux has just gotten it's open source drivers for the 200m chipset to work with 3d acceleration. I don't know if linux and macs handle the drivers in a similar way, but you might want to look at the source code of the linux driver.

If you can see from ATI Framebuffer project I already use Linux sources. May be later I found solution. Here I want to get your observation what is wrong in existing drivers.

Slice, I plugged my ATI 9250 could you precise what registers range you want, and also what you call the drivers, if there's something more than the stock kexts.

To get registers you need to install RadeonPCI.kext and type in terminal
./RadeonDump -r 0,300
it is most interesting range. In my version of RadeonDump (RadeonDumpS) I make more compact output for registers.
About other drivers - first I want to know about stock drivers
ATIRadeon8500.kext - you need no patch
...GA.plugin
...GLDriver.bundle
If you get boot into desktop with the drivers then check please OpenGL works or no. OpenGL Extension Viewer, OpenMark, xBench etc.
Thank you in advance.

if its any help i have a Xpress 1100 which doesnt ID properly (200M) even in windows Vista X64 (infact windows vista 32bit is the only OS that ID's correctly) that is in a laptop, i would really like to help, not only for my benefit but for anyone with this graphics processor (alot of asus laptops have them) i can boot and get to the desktop but no QE and i have to boot from the DVD with "rd=disk0s3 mach_kernel" because otherwise i get a artifacted image. i have been following your guide and it only partially works for my chipset.

profiler shows the Device ID as 5a62 and that i have 256MB of VRAM (even though Darwin only can find 16MB :S)

oh and im not some total noob i am newish to osx but i know my way around the terminal and kext editing (been doing alot of that to get the rest of my hardware working)

Thanks

Little Stevie

(P.S: im not requesting anything im offering in helping to get more support)

System Specs:

Celeron T530 1.6GHz 1MB L2 Cache
2GB DDR (system profiler cant pull the speed of it though)
SB400 southbridge
X1100 Graphics
80GB seagate SATA HDD 5400rpm
15.1" Widescreen
(i dont think audio wifi bluetooth need to be spec'd for you)

Find RadeonPCI.kext and RadeonDump utility, create reports and upload at the ATI Framebuffer thread.

Ok, Im back with the results.

I attached the 2 dumps, with and without drivers.
With drivers, anything that uses OpenGL will crash as soon as it tries (screensaver panel, Xbench, OpenGL extensions viewer). I joined the crashlog, I thought it might be useful.

Did this under 10.4.8, using 10.4.7 GFX kexts and OpenGL.framework

PS : Maybe you already knew but I noticed that ATIRadeon8500.kext is not unibin anymore in Leopard.

I read your reports. No answers but new questions.
You have exactly the same crash.log as me. Why?
1. You have no AGPGart so it is not problem of the AGP driver.
2. Your DevID is directly supported by Radeon8500 so it is not problem of incorrect patch.
3. You have dedicated memory while I have shared memory so it is not problem of addressing.
So I can suppose that the problem in ATIRadeonGLDriver or in OpenGL.framework.


ATIRadeon8500.kext is PPC only in Leo because Apple didn't make a whole set of ATI drivers for R200 in Intel flavour. Significant part of PowerPC driver contains in EFI that inject it in registry

But it is useless for us.

I found some contradiction. Don't know how to use the knowledge.
In X1000GA.plugin as well as 8500GA I see methods

But in IOGraphics project any version I see

Almost the same but some differencies. Is it significant?

I found in IOKitUser project by Apple some routings like GA.plugin. It is new chance for investigations.

Hi Slice,
I just returned from trip, I am posting results/errors of ATI 9800pro-i865g combo, I apologize if
this is redundant, just trying to give all info possible.
It is interesting that I have ATI Dev: 0x4e48, which is supposed to be native support in 9700.kext, yet nothing seems to work. With 9700GA plug I show QE and CI support, yet neither seem to function, with or without AGPGart.kext. Open GL fails to initialize and I will get blank black or white window. CI also gives same result. Also, with 9700GA plug and AGPGart loaded, I get very slow scrolling/window redraw even though I show QE/CI. Let me know if I can test anything.
Thanks again for huge effort,
rj

Thanks for testing. Really new results.
I see crash log is always different. Different reasons? Or different effect for a one reason?
Needs to think.

Aboud bad XBench UI result - no news. I think it is framebuffer problem and I am trying to make new one.
ATIMonitor crashes with the same reason

It is allocating region to write into display. Typical task for framebuffer.

And DVD crash with

May be Xvid is not correct?

Hi Slice,
I was thinking about doing fresh install of 10.4.11 on this machine, for sake of consistency of logging each change to system, maybe I can test each item as it is added to machine and post results. Maybe useful info as I have supposed native support in 9700.kext.
What do you think?
Also, there are so many posts with different osx versions, maybe we should test with same version? I also have Jas 10.4.8, but I have not been able to locate any earlier versions i.e. 10.4.6 etc.
Thanks,
rj

Don't know about different versions. I found that kexts from 1.4.8 works for me but 1.4.9 - no.
And I have a report that OpenGL.framework from 10.4.6 may resolve some QE problem. Advice - use older framework even in new OS version. You can find it within old drivers packages proposed in the forum.

Hi slice,
I have samsung laptop P29. with Mobility radeon 9000 IGP(devid 5835).
I had sucessfully installed 10.4.9(uphuck) and upgraded to 10.4.11
with using your ATILead, AGPGart and ATIRadeon.kext, I can boot into GUI, but it's really slow.
my shared memory settings is 128mb.
what should i do to enable QE or 3d Acceleration?
Thanks.
(Sorry for bad english)

Wow! You have exactly the same laptop as me.
Till now I have no QE and I am trying to understand why. It is not big problem for me to make a patch to somewhat. But I need to know what is needed to be patching. I need new observations, informations and ideas.

You are happy to install 10.4.11, I didn't find distr installable for me except 10.4.6.

A month no news here. Nobody knows how to investigate the problem.

I found that GA.plugin, as well as OpenGL, works in UserSpace and perform a connection to drivers in KernelSpace.
I don't understand how the system may works without it.
Without it system works in software QE mode writing graphics directly to VRAM. Without Accelerator driver such as ATIRadeon8500.kext.

I begin to understand how GA.plugin works

Continue

I probably found an error in ATIRadeon8500GA.plugin.
His pixelformats are written for BigEndianess, i.e. for PowerPC, even though it compiled for Intel.
"BGRA" instead of "ARGB" and so on.
So why I always have crash at ChoosePixelFormat.
As well as Krazubu. While we have different configurations we have the same GA.plugin.

I can correct this issue and it needs me very few days.

thanksfor your great work, please continue keeping us informed.

i wish i could help but i can't even read assembly

Now I add Ati.kext v1.0.3 to my driver set and check again with new ATIRadeon8500.kext patch.
Strange, I can't enter GUI with AGPGart 271.
Without AGPGart interface works fast and SCROLL NO MORE CRASH THE SYSTEM. Why? I think it is because of new framebuffer Ati.kext.

I see classes

but I have no (as MacMINI)

Why?
OpenGL Driver Monitor inform me that I have hardware acceleration but any OpenGL application crashes with the same log as usual.

Still enter GUI only if F8=0x00300000. I think the value is initialized in BIOS. All my attempts to correct are too late. I was most successful in second restart when BIOS is not initialize Radeon but my drivers did it. When system started with such initial values I even have hardware OpenGL with total memory 64Mb.
How to do that at cold start? Reprogram laptop BIOS or Radeon ROM?

Some thought about PixelFormat
In the picture I see it must be ARGB8888 to work. Where A=31:24, but in GA.bundle I saw A=7:0. Yes?

One more observation:
MacMini has additional driver for Accelerator

What do it?

I have partial success:
I replace 8500 drives by 9700 with renaming.
More investigations needed.

The main news and files in topic.

That was my idea long time ago.
But I never had any success. Any my maximum "programming" skills are plist editing.

Also, during one test, my motherboard died, and it was really hard (and not cheap) to find and buy the same mobo. Probably it didn't die because of that test, but I'm scarred from that point anyway.

Hi Slice,

Thanks for you work so far, I have an ATI x200m chipset (5a62) and tried the files provided. Hard reboot needed 6 times before I could get into OSX, and then worked as before.

No QE, but that's just from the system preferences, and I don't know how to test anything else. Will glady test any further files for you and report back. Asus F5 laptop btw.

I have the Kalyway 10.5.2 installed, and using Callisto 003.
Thanks
