atlee Posted March 29, 2011 Share Posted March 29, 2011 I found out connector-type=0x2 & ControlFlags=0x100 is DP_INT (DisplayPort). The "_INT" stand for internal I guess. I found this in iMac11,1's IORegistry.ACPI_i7_iMac11_1.zip nice work, i'm looking through atombios.h config for linux drivers it actually lists encoders etc in hex, I got my VGA out working perfectly using new kexts, LVDS is also activated but fuzzy so will have to work out the correct encoder. but now i have found extra info inside radeon drivers from linux hopefully i can find right values. Wondering if there is LVDS_INT and what value it would be? Link to comment Share on other sites More sharing options...

I found this in iMac11,1's IORegistry.ACPI_i7_iMac11_1.zip No, connector-type 0x400 is DP, 0x2 is connector-type LVDS. Per post #1. I've verified these personally.

kizwan Posted March 29, 2011 Share Posted March 29, 2011 Wondering if there is LVDS_INT and what value it would be? LVDS will be LVDS (as printed out by ATY,EFIDisplay). It share connector-type with DP_INT which is 0x2 but LVDS's ControlFlags is 0x40 while DP_INT's is 0x100. No, connector-type 0x400 is DP, 0x2 is connector-type LVDS. Per post #1. I've verified these personally. Yes, DP's connector-type is 0x400. Please check the iMac11,1's IORegistry I posted at my previous post. Link to comment Share on other sites More sharing options...
bcc9 Posted March 29, 2011 Author Share Posted March 29, 2011 Yes, DP's connector-type is 0x400. Please check the iMac11,1's IORegistry I posted at my previous post. Already did that before posting. And now you're agreeing with me, so perhaps you might want to rephrase your original statement? Link to comment Share on other sites More sharing options...

Look to this screenshots:- I found out connector-type=0x2 & ControlFlags=0x100 is DP_INT (DisplayPort). The "_INT" stand for internal I guess. I found this in iMac11,1's IORegistry. I'm quoting myself here. I said DP_INT's connector-type is 0x2 is based on the iMac11,1's IORegistry. The "DisplayPort" can be seen in the iMac11,1's System Profiler (included in the zip file). I didn't said DisplayPort's connector-type is 0x2. The DisplayPort's connector-type is 0x400. The DP_INT's connector-type is 0x2 based on the iMac11,1's IORegistry.

bcc9 Posted March 29, 2011 Author Share Posted March 29, 2011 So the point is that the LVDS connector is apparently being used in a displayport mode (when controlflags is set to 0x100 on an LVDS connector). Ok I get it now Link to comment Share on other sites More sharing options...
atlee Posted March 29, 2011 Share Posted March 29, 2011 I decided to go on a little test, i think the control flags have everything to do with if and how the screens switch on. Let's take Douc as an example i know it has only 2 outputs but i can apply this method to most 5xxx personalities. Personality: Douc ConnectorInfo count in decimal: 2Disk offset in decimal 507704 02 00 00 00 00 05 00 00 09 03 00 00 21 03 02 02 00 04 00 00 04 02 00 00 00 03 00 00 11 02 01 01 If i have control flags 14,14 both screens switch on, if i decide to change LVDS to 40 then LVDS switches off, leaves VGA on. I was merely looking at how Apple do it in the Uakari personality and they have DP controlflag 14 and 200 connector using 14, so decided to copy and it seems to give me 2 screens that has QE/CI with both mirror or extended. LVDS does show as CRT but i was just feking around to look at the behavior. Also 00,00 seems to be VGA which i can apply this method to any personality also. LVDS seems to function when i use the same control flags, changing to 40 and 10 i lose 1 screen. 14,14 both screens turn on, will play around more. the 2 personalities that match my card are Baboon and Eulemur. but I'm playing around with Douc to see if i can perfect VGA,LVDS before proceeding to HDMI. Patched Douc 02 00 00 00 14 00 00 00 09 03 00 00 01 12 02 07 10 00 00 00 14 00 00 00 00 71 00 00 00 00 01 08 @Kizwan any sort of reason to why i would get this sort of behavior? Also VGA 10 CntrlFlag and LVDS 14 work as mirror and ext as well. Link to comment Share on other sites More sharing options...

Fjtorsol Posted March 29, 2011 Share Posted March 29, 2011 I tried randeondump tool 0.2 with my Mobility Radeon HD 2600 XT VBIOS and showed me the following error: "ATOMBIOS signature not found". I need to get i2C ID's for my connectors to get the SenseID's/SenseLines. By trying random SenseID's I got ATIFramebuffer to read the LVDS EDID and detect the screen (as main in extended desktop mode) but the screen remains black and the backlight shutsdown after the Apple gray page is shown. Misteriosly my VGA port seems to have many valid SenseID's and each shows VSync tearing in a different area of the screen.Do you know any other way to get these values from other utilities, Linux or Windows??

Well, you could follow the guide and get dmesg from RadeonHD by booting your system with RadeonHD.kext installed, opening terminal, and typing "sudo dmesg" Or you could get the same info from Linux by booting Ubuntu CD Or you could read from the Linux code mucha quoted 682 /* 683 * DIG Encoder/Transmitter Setup 684 * 685 * DCE 3.0/3.1 (RV6XX, Radeon HD 3XXX Series and older) 686 * - 2 DIG transmitter blocks.

Misteriously only with 0x07 the LVDS EDID is assigned to the first of the two personalities but anyway the first personality is atomatically associated with TMDS1 => HDMI so what I get is the LVDS EDID assigned to HDMI output and no way to connect with LVTMA. The strange thing is that the i2CID of the LVDS is 0x15 and the working ones (VGA and HDMI) start with 0x90. Even the bootloader assings a TMDSA (TMDS1) display type to the device-properties of the connector. Is there any way to associate the LVTMA (connector index 0) with the first personality?? Would it work if I change the Hypoprion DATA XREF to a set of 3 personalities?? Link to comment Share on other sites More sharing options...

First of the fact is the Chameleon from trunk does injects 2 ports but it doesn't mean it map only to 1st 2 connections in the framebufer's connection table. It's only means, at the same time only two ports can be use (up to 2 monitor). For mobility card or notebook, the first port always reserved to LVDS. I did tried putting LVDS connection at the 3rd row in the framebuffer's connection table but it still connected to first port (to be precise at port @0). I think the arrangement has to do with HotplugID (I hasn't experiment with it though but based on mucha's guide the HotplugID did responsible in the arrangement). The 2nd port (port @1) will be shared, e.g. in my case 2nd port will be shared by VGA & HDMI. So the monitor configurations on mine are LVDS+VGA & LVDS+HDMI. I don't have another external monitor to test whether my notebook can support 3 displays configuration (at the same time) or not. Kabyl's boot file is the best choice if anyone want to setup more than 2 displays. I found (someone else already found about it, I just tested it to proved it does happen) when LVDS connection is at the last row in the framebuffer's connection table (after VGA or HDMI), both VGA & HDMI will unable to detect monitor plugged in to either ports (not detected in IORegistry).

Fjtorsol Posted March 31, 2011 Share Posted March 31, 2011 After getting the i2C values for the iMac 8,1 Mobility Radeon HD 2600 XT and comparing with mine: iMac 8,1 Mobility Radeon HD 2600 XT ATOM BIOS Rom: SubsystemVendorID: 0x106b SubsystemID: 0x0083 IOBaseAddress: 0x0000 Filename: 13B22504.101 BIOS Bootup Message: M76XT B22504 MXM GDDR3 256M 680e/750m Connector at index 0 Type: DVI-I (2) Encoder: id: 15 name: INTERNAL_KLDSCP_DAC1 i2cid: 0x90, OSX senseid: 0x1 Connector at index 1 Type: DVI-I (2) Encoder: id: 13 name: INTERNAL_KLDSCP_TMDS1 i2cid: 0x90, OSX senseid: 0x1 Connector at index 2 Type: LVDS (7) Encoder: id: f name: INTERNAL_LVTM1 i2cid: 0x91, OSX senseid: 0x2 Connector at index 3 Type: DVI-I (2) Encoder: id: 16 name: INTERNAL_KLDSCP_DAC2 02 00 00 00 40 00 00 00 09 00 00 00 00 01 01 12 00 10 00 00 16 00 00 00 C4 00 00 00 10 00 02 11 AMILO XI 2528 Mobility Radeon HD 2600 XT ATOM BIOS Rom: SubsystemVendorID: 0x1734 SubsystemID: 0x1107 IOBaseAddress: 0x0000 Filename: 26832C.bin BIOS Bootup Message: ECS_P75IM0_M76XT M76 GDDR3_16Mx32 128bit 256MB 300e/700m Connector at index 0 Type: LVDS (7) Encoder: id: f name: INTERNAL_LVTM1 i2cid: 0x14, OSX senseid: 0x5 Connector at index 1 Type: 9 pin DIN (9) Encoder: id: 16 name: INTERNAL_KLDSCP_DAC2 Connector at index 2 Type: HDMI-A (11) Encoder: id: 13 name: INTERNAL_KLDSCP_TMDS1 i2cid: 0x91, OSX senseid: 0x2 Connector at index 3 Type: VGA (1) Encoder: id: 15 name: INTERNAL_KLDSCP_DAC1 i2cid: 0x90, OSX senseid: 0x1 Considering: LVTM1 = LVTMA TMDS1 = TMDSA DAC1 = DACA Connector i2CID 0x91 | Personality 1 iMac 8,1 => INTERNAL_LVTM1 (LVDS) AMILO XI 2528 => INTERNAL_KLDSCP_TMDS1 (HDMI-A)* *Should be associated with LVTMA (LVDS + HDMI-A), standalone TMDSA won’t work. Connector i2CID 0x90 | Personality 2 iMac 8,1 => INTERNAL_KLDSCP_DAC1 (DVI-A) & INTERNAL_KLDSCP_TMDS1 (DVI-A) AMILO XI 2528 => INTERNAL_KLDSCP_DAC1 (VGA)* *Should also be associated with TMDSA (HDMI-A). Conclusion: - LVTM1 I2CID 0x14 => Out of range for personality association I2CID’s should be renamed in VBIOS according to the following: - LVTM1 I2CID should be 0x91 (currently 0x14) - TMDS1 I2CID should be 0x90 (currently 0x91) - DAC1 I2CID is 0x90 and requires no changes Personalities won't require to be edited after such changes. This explains why VGA works and HDMI is associated with the first personality where 0x05 as a SenseID doesn't work. Now I need to guess how to hexedit the VBIOS to rename such i2CID's Link to comment Share on other sites More sharing options...
atlee Posted April 1, 2011 Share Posted April 1, 2011 I'm off to get Lion 10.7 DP2 11A419 to have a looksy and also see what the newer ATI kexts can do for me Link to comment Share on other sites More sharing options...
kizwan Posted April 1, 2011 Share Posted April 1, 2011 I'm off to get Lion 10.7 DP2 11A419 to have a looksy and also see what the newer ATI kexts can do for me Any progress on the LVDS? Is it still working on mirror mode with external monitor? What happen to LVDS when external monitor is not connected? Link to comment Share on other sites More sharing options...
