New ATI Drivers

omni · January 25, 2006

ok before to go sleep i do deassembly ATIDriver.bunle

and i can't see EFI involved in some way for now but need to that be check deeply

but there is new think like AppleSence seems to work on 10.4.4 - also IODisplay too

that very big progress from apple side, need also to checkout darwin last sources - strange they are PPC only for now ...wonder why (http://darwinsource.opendarwin.org/10.4.4.ppc/)

tomorow i will deassembly rest ATI**.kext's

good night

I believe the reason you are not seeing any references to EFI is because the ATI firmware is stored in the FlashROM and loaded at power on time, just like it would if you had a normal Mac ATI graphics card. The ATINDRV uses IONDRVDevice to find the Radeon chip and it's ROM, VRAM etc (remember the NDRV.cpp you had me look at, it has the loader for ROM there) so I guess ATINDRV is based on something like that, afterall it instantiates IONDRVDevice.

Now that you mention it, perhaps it would be interesting to try the new Apple kexts for AppleSense, I2C, AppleBackLight etc...

anyone knows if the mousetearing bug and the mouse break after opengl is gone with the news kext of the 10.4.4? or only works for X1600 on real MAC?

Tek_No · January 25, 2006

Just grabbed the framework files, took a backup of my current ones (luckily enough) and copied the new ones over the existing ones. A reboot and no more desktop...

Just restored back to previous situation now...

cyclonefr · January 25, 2006

and if u had the latest framework with the 10.4.4 kext?

Independent verification that I didn't just screw it up... yea!

Tek_No · January 25, 2006

Dunno if I understand your remark correctly but I was using the 10.4.4 ATI kexts (8500 for my 4c66 Radeon 9000) as found in the other topic in combination with the 10.4.4 frameworks as posted on rapidshare...

Tek_No · January 25, 2006

By the way: do we already know the meaning of "Accel caps:" as found in the WindowServer log?

Whenever I'm not trying to use the ATI driver and the modified AppleI386PIC.kext the log says: Accel caps: 00000000 so I guess this is something like "disabled"...

Whenever i get the black with white stripes desktop (ATI kext loaded and AGP bridge loaded) the log reads: Accel caps: 00000001

Now apparently other have a value of 00000003 for Accel caps...

What is this value telling us???

munky · January 25, 2006

perhaps 0000003 is PCI-E ?

my source has just emailed me the frameworks, which was nice of him, but i guess we dont need them any more.

Same here. With 10.4.4 Framework (OpenGL and AGL) plus 10.4.4 Ati kexts (for my 9600pro -> ATIRadeon9700*) the login screen appears in his full beauty but when I'm trying to login he drops me to the console login.

Tek_No · January 25, 2006

Kossi, that is the exact same behaviour as I had (login and back out again): I guess next time I need to be a bit more specific :graduated:

I first tried keeping the new OpenGL.framework and only restoring the AGL.framework but that didn't bring the desktop back...

munky · January 25, 2006

np_ said he was going to disassemble the driver to see why its not matching. i guess its something to do with this ATY/Wormy thing.

with a bit of luck he'll be posting some good news on that front soon :graduated:

witch mean OpenGL framework depend on one or more frameworks from 10.4.4 ( function missing in that framework )

drop you in console because window server fails to load

there is two framebuffers one for console ( startup ) and one for UI - they switch on login exacly

i don't have time now to check that deep but at weekend i will do

thanks

wishbone · January 25, 2006

just black screen after the gray MAC boot screen . any one have a solution

munky · January 25, 2006

dude... read the thread. thats what we're working on.

Omni , i can tell you there is no EFI involved from this i see , need more diassembly to be %100 sure

for example i get AppleYukon.kext from 10.4.4 and work perfect under 10.4.3

if there was some depence on EFI no way to work at all

also IONDRVDevice is replasment for nub then find some of these "NVDRV's" or there is second head present ( see IONDRVFRamebuffer look for "device_type" = "display")

apple treat two head video card as two single head cards , because you can't have two cards using same i/o resources - here comes IONDRVDevice

simple

munky · January 25, 2006

np_: so you think the ATI driver is not dependant on EFI? that would be excellent news

that mentions EFI device? (not mentioned anywhere else though, but there must be a check or something for profile to mention it).

np_ · January 25, 2006

i think if EFI have something to do with ATI**.kext's from 10.4.4

they will be not able to load at all ...

but from xiberia post i can see EFI is used for "display" ie LCD and mostly info for windows server

but i can be wrong on all this too ...

i don't have time to play with ATI**.kext's now but at weekend i will check whole think deeply

I agree with you on this one... seems pretty logical.

*can't wait for this weekend*

rjtd · January 25, 2006

Greets,

I have a X800GTO and I get the same problems as with the 10.4.3 Kext. The screen does not go black, just garbled.

Also, I tried VNC the MacOSX just to give it a try, and the same thing happens.

One more things I tried was to VNC an working MacOSX when I put @refreshrate, and I can change res on the VNC app. On my real monitor, I only see ascii text.

munky · January 25, 2006

your efforts are much appreciated, np_

cheers and big ups

ajv · January 25, 2006

witch mean OpenGL framework depend on one or more frameworks from 10.4.4 ( function missing in that framework )

drop you in console because window server fails to load

The ATIRadeonX1000GLDriver (the one that fixes the blackout when removed) depends on:

/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGLProgrammability.dylib (compatibility version 1.0.0, current version 1.0.0)

/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGLImage.dylib (compatibility version 1.0.0, current version 1.0.0)

/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 368.26.0)

/System/Library/Frameworks/IOKit.framework/Versions/A/IOKit (compatibility version 1.0.0, current version 275.0.0)

/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version 7.4.0)

/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)

/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.3)

So at least otool -L doesn't think there are any missing dependencies.

munky · January 25, 2006

what about running otool on the main kexts?

on another note, this weekend is my birthday, so if np_ finds something useful, it will be the best birthday present ever

cheers

vince29 · January 25, 2006

I've been reading quickly through this thread and I noticed that some thought that the blackscreen with only the cursor working could be due to the use of EFI. I don't think so.

I have the same problem with my x700 when I try to use 10.4.3 or 10.4.4 ATIRadeon9700 and ATIRadeon9700GL. It "works" without the GL bundle, without QI or CI, and turn to this black screen when it is installed. And there was no EFI with 10.4.3.

I know this post may not be very helpful, but it would be a loss of time seaching after EFI if it is not involved.

the ATI driver is ATINDRV.kext

rest ATI(model).kext is just IOAccelerator loading ATI(model)GL/GA plugins

most import think is to get ATINDRV.kext loaded and running for now ( there is framebuffer ..etc )

and from diassembly i can see is much more complete that older versions

but still can't find noone depency on "EFI"

can some one do this

remove all ATI*.kext exept ATINDRV.kext

reboot and try to load kextload -vt /System/.../ATINDRV.kext

let us for results ( log output and ioreg -l out )

thanks
