for his genius discovery and for his method for finding and editing framebuffer personalities I was planning to add this to bbc9 topics, but i couldn't add a replay only a new topic in new users lounge is allowed for me (I'm a member since 2006 ),so if a moderator can attach it it's welcome.
Most credit should go to bcc9 (radeondump & tutorial) & Dong (RadeonHD), this was not possible without his finding ,a previous knowledge of bbc9 method with some basic binary editing and terminal skills is a must have.
Sorry for my bad English and my Bad teaching skills, the most important is the idea.
Any additional useful information and feed-back is welcome
The bootlaoder is chameleon rev 747 with modded ati.c with corrected default framebuffer to Shrike and model name for my DeviceId: 0x9480 (Kabyl boot file is no go for me).
The Guide (HowTo.rtf outdated ) in the attachements with some usefull files for quick editing
I have received many PM from people asking for my patched kext, i have uploaded them with my boot file, remember those files are specific for Mobility Radeon 4650 on a HP Pavilion DV6 series & there is NO guaranty they will work on other models
http://www.megaupload.com/?d=4SN7VDMK
http://hotfile.com/dl/113477176/da80b51/ATI.zip.html
Updates:
1- the same method is tested in Mac OS X version 10.6.3 & the lastest update 10.6.7 and i report it's working perfectly for both
2- for the 10.6.3 system the personnality is 20 bytes (the SenseID byte is replaced by i2cid & SenseID is 4 bytes);
a-the original 10.6.3 Shrike ConnectorInfo:
02 00 00 00 40 00 00 00 09 00 00 00 02 01 00 00 03 00 00 00 02 00 00 00 00 01 00 00 09 01 00 00 20 01 02 91 02 00 00 00 00 04 00 00 04 03 00 00 00 01 00 00 10 00 01 90 01 00 00 00
b-My modded working 10.6.3 Shrike ConnectorInfo :
02 00 00 00 40 00 00 00 09 00 00 00 12 00 00 96 07 00 00 00 10 00 00 00 10 00 00 00 00 01 00 00 00 10 01 95 06 00 00 00 00 08 00 00 00 02 00 00 00 01 00 00 20 01 02 90 01 00 00 00
3- About the 10.6.7 Update:
a-ConnectorInfo are located in ATIFramebuffer.kext for the general combo update (the same as 10.6.6 system)
b-ConnectorInfo have migrated to ATIControlerXXXX.kext for 2011 MBP update (the kernel & ATi Drivers structure are closer to Lion 10.7 than to 10.6.6),
ATIController4600.kext contain only Shrike, Flicker & Gliff ConnectorInfo (which theorically restrict the possible framebuffer to use with a specific controller.kext)
ATIController4800.kext contain only Cardinal,Motmot & Quail ConnectorInfo.
The Online guide:
A- The Structure of a personality:
I'll take Shrike as framebuffer for the demonstration, cause it's used as default by Radeon HD 4670 (M96XT, DevID 0x9488 ) on iMac 10,1 & iMac11,2
which is the closest to the Mobility Radeon HD 4650 (M96, DevID 0x9480) on my board.
for Shrike we have by default 3 personalities , one for each connector (3 connectors allowed): port0, port1, port2.
02 00 00 00 40 00 00 00 09 01 00 00 02 01 00 03
02 00 00 00 00 01 00 00 09 01 00 00 20 01 02 02
00 04 00 00 04 03 00 00 00 01 00 00 10 00 01 01
let's take the first one which is for port 0 :
02 00 00 00 40 00 00 00 09 01 00 00 02 01 00 03
divide it to 8 parts:
02 00 00 00 - 40 00 00 00 - 09 01 - 00 00 - 02 - 01 - 00 - 03
Then byte swapped
1- ConnectorType : 02 00 00 00 > 0x00000002 - - -
2- ATY,ControlFlags : 40 00 00 00 > 0x00000040 +++
3- Features : 09 01 > 0x0109 +++
4- Unkown : 00 00 > 0x0000 - - -
5- Transmitter : 02 > 0x02 - - -
6- Encoder : 01 > 0x01 - - -
7- HotplugID : 00 > 0x00 - - -
8- SenseID : 03 > 0x03 ++++++
- - - > Value not important, but need to be accurate for better result
+++ > Important value, incorrect value == not working personality
Detailed info about possible value for each field is list below ( some are confirmed, some only guessed by studying different personalities and need some feed-back
from working system (for me LVDS and VGA value are confirmed)
1- ConnectorType;
/* 4 byte ,from bbc9 radeondump */ #define CONNECTORTYPE_LVDS 0x00000002 #define CONNECTORTYPE_DVI 0x00000004 #define CONNECTORTYPE_VGA 0x00000010 #define CONNECTORTYPE_S-V 0x00000080 #define CONNECTORTYPE_DP 0x00000400 #define CONNECTORTYPE_HDMI 0x00000800
2- ATY,ControlFlags;
/* 4 byte the same as found on ioreg key: ATY,ControlFlags. hardcoded for each connector type u can try one by one until u find the working one for u 0x0002 : LVDS > ControlFlag : 0x0040 / 0x0100 0x0004 : DVI-? > ControlFlag : 0x0016 - 0x0014 / 0x214 0x0010 : VGA > ControlFlag : 0x0010 0x0080 : S-Video > ControlFlag : 0x0002 0x0200 : DVI-? > ControlFlag : 0x0014 / 0x0214 - 0x0204 0x0400 : DisplayPort > ControlFlag : 0x0100 - 0x0104 - 0x0304 / 0x0604 - 0x0400 0x0800 : HDMI > ControlFlag : 0x0200 0x1000 : DVI-? > ControlFlag : 0x0016 */
3-Features;
/* Features byte 0 , for example for LVDS screen it's almost 0x09 = 0x01 + 0x08 > Internal + Backlight */ #define FEATURE_USE_INTERNAL 0x01 #define FEATURE_USE_RGB_ON_YUV 0x04 #define FEATURE_USE_BACKLIGHT 0x08 #define FEATURE_BACKLIGHT_INVERTED 0x10 #define FEATURE_USE_CLAMSHELL 0x20 /* 1 byte, hardcoded for each connector type 0x0002 : LVDS > Features : 0x09 0x0004 : DVI-? > Features : 0x00 0x0010 : VGA > Features : 0x00 0x0080 : S-Video > Features : 0x04 0x0200 : DVI-? > Features : 0x00 0x0400 : DisplayPort > Features : 0x00 0x0800 : HDMI > Features : 0x00 0x1000 : DVI-? > Features : 0x00 */ /* Features byte 1 , no idea ???*/
4- Unkown ;
5- Transmitter;
/* u can get this from dmesg after installing Dong's RadeonHD with debug info */ /* Transmitter Bits 0-3 (TransmitterID) */ #define UNIPHY 0x00 #define UNIPHY1 0x01 #define UNIPHY2 0x02 /* Transmitter Bits 4-7 (LinkID) */ #define DUALLINK 0x00 // LINKA + LINKB #define LINKA 0x10 #define LINKB 0x20 /* Transmitter byte */ #define UNIPHYA 0x10 // = UNIPHY:LINKA #define UNIPHYB 0x20 // = UNIPHY:LINKB #define UNIPHYAB 0x00 // = UNIPHY:DUALLINK #define UNIPHYC 0x11 // = UNIPHY1:LINKA #define UNIPHYD 0x21 // = UNIPHY1:LINKB #define UNIPHYCD 0x01 // = UNIPHY1:DUALLINK #define UNIPHYE 0x12 // = UNIPHY2:LINKA #define UNIPHYF 0x22 // = UNIPHY2:LINKB #define UNIPHYEF 0x02 // = UNIPHY2:DUALLINK #define DACA 0x00 #define DACB 0x10
6- Encoder;
/* u can get this from Dmesg as above for R8XX architecture and above there is 06 Digital Encoder: DIG_1 > DIG_6*/ /* Encoder Bits 0-3 (DIG_ID : Digital) */ #define DIG1 0x00 // = DIGA #define DIG2 0x01 // = DIGB #define DIG3 0x02 // = DIGC Only for Radeon HD 5XXX Series and above #define DIG4 0x03 // = DIGD Only for Radeon HD 5XXX Series and above #define DIG5 0x04 // = DIGE Only for Radeon HD 5XXX Series and above #define DIG6 0x05 // = DIGF Only for Radeon HD 5XXX Series and above /* Encoder Bits 4-7 (DAC_ID : Analog) */ #define DAC 0x10
7- HotplugID;
/* 4 bits it's a unique id for each port, i have tried with 0 for port0, 1 for port1 and 2 for port2 and it's just working */
8- SenseID;
/* SenseLine = (i2cid & 0xf) +1 ,you get i2cid from bbc9 radeondump */ Bits 0-3: Sense Line Bit 4: Use hw i2c flag
Now to some practice
B- Getting the ConnectorType, ATY,ControlFlags,Features, HotplugId and SenseLineId Values:
You will need :
1- videocard bios dump ( i have used everest for that and renamed it 1002_9480.rom ) ,
2- radeondump tool from bbc9
launch Terminal & type ./radeondump < your_videobios.rom > connector.txt
you will get something like this :
Desktop Mucha$ ./radeondump < 1002_9480.rom ATOM BIOS Rom: SubsystemVendorID: 0x103c SubsystemID: 0x3629 IOBaseAddress: 0x7000 Filename: br33507.001 BIOS Bootup Message: HP_Quanta_Jones_Cujo_M96M_DDR3 M96 DDR3 128bit 550e/667m Connector at index 0 type: LVDS (7) Connector's i2cid: 96 Connector at index 1 type: VGA (1) Connector's i2cid: 95 Connector at index 2 type: HDMI-A (11) Connector's i2cid: 90
which means:
port0 > LVDS=0x00000002 - ControlFlag=0x0040 - Features = 0x09-------------------------HotplugId=0x00 - i2cid=96 > SenseLine = 0x07
port1 > VGA =0x00000010 - ControlFlag=0x0010 - Features = 0x00 ------------------------ HotplugId=0x01 - i2cid=95 > SenseLine = 0x06
port2 > HDMI=0x00000800 - ControlFlag=0x0200 - Features = 0x00 -------------------------HotplugId=0x02 - i2cid=90 > SenseLine = 0x01
C- Getting the Encoder & Transmitter ID Values:
For some useful info you may visit : "http://www.botchco.c...om/agd5f/?p=51"
and some Encoder-Transmitter Routing rules taking from commentary of linux drivers
"http://lxr.free-elec...eon_encoders.c"

You need Dong's RadeonHD.kext , i have used the 10/20/2009 update, edit the info.plist to set the debug to true and verbose level to 2
then delete ATI4600 & ATIFramebuffer from S/L/E (make a back-up first) and install radeonHD reboot (your external VGA,DVI or HDMI screen most be connected)
once on desktop go to Terminal : sudo -s , type your password then dmesg >Encoder.txt
In my case i get as output:

Based upon the above information my SPECIFIC videocard routing is:
CRTC0>DIG1>UNIPHYE>LVDS Encoder= 0x00 Transmitter = 0x12
CRTC1>DAC > DACA >VGA Encoder=0x10 Transmitter = 0x00
CRTC1>DIG2>UNIPHYB>HDMI Encoder= 0x01 Transmitter = 0x20 (i don't have a hdmi display to test)
Now doing the compilation , my new modded Shrike personalities :
02 00 00 00 40 00 00 00 09 01 00 00 12 00 00 07 LVDS
10 00 00 00 10 00 00 00 00 01 00 00 00 10 01 06 VGA
00 08 00 00 00 02 00 00 00 01 00 00 20 01 02 01 HDMI
This mod allowed me to get both LVDS an VGA display working with Resolution change, QE/CI Extended desktop and Mirroring
I have tested the same mod with Peregrine and i confirm it's also Working.
D- How to Easy Quick Patch your desired Framebuffer personality (without calculating the adresses and for both i386 and x86_64):
You should have a hexadecimal editor:
1- Download the attached : Sharks_FB.txt Birds_FB.txt and Monkeys_FB.txt,
2- Open the text file select and copy the desired personality hexadecimal code (the one you want to patch),
3- Open ATIFramebuffer.kext and Drag ATIFramebuffer binary to hexadecimal editor,
4- Select : edit>search , in the search fields paste the clipboard content and choose hex value & wrap option,
5- You should find 2 instances of the searched personality: the first one is for x86_64 and the second for i386 (make sure you have only 2),
6- Patch and save your binary, install reboot an ENJOY
For Radeon HD 3XXX and prior choose Sharks,
For Radeon HD 4XXX choose Birds,
For Radeon HD 5XXX choose Monkeys.
