ATI Radeon Mobility users wanted

Hi everybody, some new ideas are coming to enable output support for mobility cards and maybe later generalize it to all the ATI boards that have supported GPU but give no output.

 

Please post your DSDT here and wait here for some news and trials.

 

Please precise the following :

- Your GPU model

- If you have QE/CI (or know it should have it)

- The present external video outputs (DVI, VGA, TV etc...)

- How it's working currently (eg : QE/CI working on external VGA, internal LCD not working).

 

 

To dump your DSDT, use the utility joined here :

- extract it on your desktop

- launch terminal

- cd ./desktop/dsdtdump/

- ./getdsdt.sh

- upload the file "dsdt.dsl"

DSDTdump.zip

Asus A8Sr with Mobility HD2400.

 

BIOS modded by Kabyl (remove some alias thing)

 

dsdt.dsl.gz

 

Glad if I could help.

 

Edit for more information:

- DevID: 1002 94c9

- Internal monitor not working with ATIRadeonX2000.kext

- External monitor works CI/QE with ATIRadeonX2000.kext and netkas' Natit.kext (Iago).

@Nick12, not really since there's no working FB for those chips.

 

@PainWarlock, ok thx, I need dumps from supported GPUs.

 

@robertoSTUDIOS, do you have extended desktop working ?

 

 

No...

Only in Internal LCD: NativeRes, QE/CI, with modded ATIinject

(But only nativ res... if i change res i see mouse but only blue screen, and i close the Laptop Lid and reopen screen is scrambled)

And some computer restart effects works good smooth like the velvet, some times slow and choppy ;)

Okay so I am guessing that PainWarlock has the same Mobility HD 3450 card that is in my Dell Studio....

@Krazuba does this mean you do not want the dump from us?

I have messed around with it some I have the card recoginzed under about this mac running the 9f23 installer and then overlaying the updated ATi drivers from Apple and addind a EFI string but I still have no res . options and no QE/CI.......

Very interesting problem! I shall help if I can.

 

what about the X1350 in my sig ?

In the first order!

 

For testers.

Please say your deviceID. It is important for analysis.

@ Ridgeline - No person has given him adequate information as of yet, plus the 3650 he listed is not a mobility judging from his sig, so I would reccomend doing a full dump and full information, For example you might put...

 

Ridgeline, you need to upload your dump here yet! Below is all the information (outside of a dump) on his specific card, I've been working with him on and off throughout his trials, so I know a bit about it (I have a similar card, Mob HD 3650, for my dell studio 17 - but I currently have vista on my machine again and am using it for projects - so I will only wipe it again if there is some progress made on this front.  If it works for him, I am confident it will work for the 3650s as well, we've had identical problems every step of the way).

 

@ Krazubu - Thank you for this effort, if you make progress, it would mean a great deal to me, I have been frustrated and semi-obsessive about this for some time, and cannot make progress. Please take the information below along with either a suitable dump for the Mobility HD 3450, or should he produce one (I'm sure he will soon enough), whatever Ridgeline can provide you with (he's set up good for recovering from test failures, so work with him on this in place of me as I do not have OSX in my laptop at the moment).

 

COMPUTER (lappy) MODEL:

 

- Dell Studio 15

 

- Model Version 1535

 

GPU model:

 

- ATI Radeon Mobility HD 3450

 

- Ven ID=1002, Dev ID=95C4  ( For ease of use: 0x95C41002 )

 

- GPU Chipset Series = M82

 

QE/CI Support Status

 

- No QE/CI - Scrambled screen every time a solution is tried to implement QE/CI

 

- Have found traces of card ID while hex editing in certain x2000 files, so I believe there is a way to make this work to a point further than "scrambled screen" or "black screen"

 

Video Outputs

 

- My laptop has the following Video Outputs : Internal LCD, VGA, HDMI

 

- Can get "decent" resolution modding the boot.plist with a higher res, but it does not reach "maximum" resolution this way.

 

How is it working?

 

Currently it runs fine with no QE/CI.  QE/CI is the major hurdle.  We've tried:

 

- every injector / plist edit out there

- custom modified injectors so that they were geared specifically towards my card

- tried EFI mods

- tried several different versions of the many kext files floating around, old and new

- tried all of the "installers" people reccomended to try

- tried several "quirky" fixes, like plugging something in to the VGA/HDMI ports and watching for changes

- tried hex-editing executable x2000 files to make them function specifically to my card, in place of similar cards

 

 

& A follow up note for whom it may concern real quick:

Even though it is not the newest "driver" revision out there, the Latest NVinstaller looks the most promising and would probably be a good place for you to start, it had the most promising looking references to our card models (3450 mobility / 3650 mobility) I have seen while hex editing the x2000 files. The other note though, is that the EPS/NATIT installer from last-exile uses a method with two megalodon files that get loaded, instead of the normal "one". I do not know how to make the newer NVinstaller files make use of two megalodons - but the old executable (the one from the eps/natit/lastexile installer) has zero references to the 3450/3650 mobility cards that I could find whatsoever, so its no suprise that it isn't working with that installer. Not sure if this will be of use to you, this is just where I left off in my trials.

The goal here is to gather some DSDTs from systems with working displays so we can compare them with those from systems with "dead" LCD. Maybe we'll find the required conditions to bring it back to life.

However, if you don't have QE it doesn't bring any info since the LCD allways works in VESA mode. Also, it's pointless to fix something that only matters when QE is working for a GPU that doesn't have it.

 

@ Slice

Sure, help is welcome, the interesting part is the _DOD string (32 bits).

What we know so far FOR NVIDIA and the pending questions are :

- Is it required : no

- Can it break support : yes (meaning it's sometimes better to just remove it, a laptop has already been fixed this way yesterday)

- Can it help if it's set properly to what OSX uses/wants to see : ???

 

You can find some details about it in the ACPI specs PDF around the page 570. The description of the string is still rather obscure despite the explanations and examples in this guide.

 

Now about ATI, we know that HD mobility series don't work, probably because the drivers are designed for DVI/VGA output whereas laptops need LVDS. The idea behind is to mess with this string and make the kext treat this internal LCD as a classic display, not sure it's doable, but it worth a shot.

Thanks, Fuji......

@Krazuba when you get to that point let me be guinea pig... I have several partitions all the same setup and would be willing to try anything to get this working. He** I would probably pay to get this working...

Thanks

@ ridgeline and Fujilives, it's still unclear if it's a GPU support problem or output problem. If you have any way to check if the computer is "mentally" working with QE it would help (SSH maybe). Also ensure you entered your EDID properly, it's important with ATI mobility cards.

I tried remote-desktopping in, it let me in, but it was still just as bad, perhaps I just have to accept the fact that there will never be support, and these cards are just a lost cause, I appologize for wasting your time, I thought you wanted information on cards who, when QE/CI was turned on, gave scramble or black screen.

Hi, my mobility HD2400 is fully working in external VGA (not yet try DVI) monitor (QE/CI) with original ATIRadeonX2000.kext and Natit.kext by netkas. Its devID is 94C9 (listed by default in Info.plist). I posted the dump on the first page.
