On linux:

There are two digital output blocks in the 5xx and 6xx ASICs, which handle TMDS (the signalling for DVI and HDMI) and LVDS (the signalling for internal LCD panels). They sort of correspond to "digital output 1" and "digital output 2".

 

The first block is TMDS only, and is called TMDSA (ie the first TMDS block).

 

The second block can output TMDS or LVDS, and is called LVTMA (ie LVds plus TMds A or the first LVTM block).

 

The two blocks are programmed differently. While we were preparing the initial documentation for 5xx and 6xx display logic we realized at the last minute that the information for the LVTMA block was missing from the documents. We were able to replace the 5xx document with a new one containing most of the 5xx LVTMA info but were only able to get the updated 6xx LVTMA info to Novell a few weeks ago. I'm hoping to get the same info posted publicly over the next week or two.

 

As a result, until very recently if you had a card with dual DVI connectors there was a pretty good chance that one DVI connector (the one wired to the TMDSA block) worked and the other (the one wired to the LVTMA block) did not.

 

Hope this helps.

 

I'd ask OP to post the ioreg -l of his configuration to see how is recognized his working internal display.

Another info. With Transmitter set to 12 (linkA) the display is listed as TMDSA, with 02 (supposedly A+B dual link), is listed as TMDSB (LINK2). TMDS is not LVDS..I think is used on DVI displays? Imac connection shows LVDS. Check the logs and let me know.

I already tested this, apparently the ATY,EFIDisplay is only cosmetic/information. Change it doesn't make the internal LCD usable or not. It also hardcoded in ati.c (trunk). I even change it to LVDS (mine was TMDSB) but all monitors still working.

you are right the ATY,EFIDISPALY reported by the ioreg dump is injected by chameleon bootloader Not detected by the drivers & only cosmetic

 

but as he reported :

 

TMDS-A (HDMI-A & Single Link DVI) are Single Link,

TMDS-B (HDMI-B & Dual Link DVI) are Dual Link,

LVDS is Single Link, but for some High Resolution Internal LCD is Dual Link.

What resolution do you have on your display? And mucha's one?

 

I see a dual-link value enabled in the imac ioreg, plus several more defined values that are not present in our ioregs. I think the problem lies in the connection configurations in the ati.c file in the bootloader. I am checking it right now. I think we have to edit the ati.c file that is lacking some values to get some lvds displays working. It would be useful to talk with the developers behind the ati injection, they probably would find the issue much faster than me.

also I have a Sony Vaio (VGN-NW21EF) but it lacks the i2cid of LVDS

 

ATOM BIOS Rom: 
SubsystemVendorID: 0x104d SubsystemID: 0x9056
IOBaseAddress: 0xd000
Filename: BR34079.001 
BIOS Bootup Message:

Connector at index 1 type: VGA (1)
Connector's i2cid: 90
Connector at index 2 type: HDMI-A (11)
Connector's i2cid: 94

 

I noticed this:

GPIO_I2C_Clk_Mask: [b]0x1f90[/b]
GPIO_I2C_Clk_Mask_Shift: 0x0
GPIO_I2C_Data_Mask: 0x1f90

GPIO_I2C_Clk_Mask:[b] 0x1fc4[/b]
GPIO_I2C_Clk_Mask_Shift: 0x0
GPIO_I2C_Data_Mask: 0x1fc4
GPIO_I2C_Data_Mask_Shift: 0x8
I2C bus "RHD I2C line 4" initialized.
GPIO_I2C_Clk_Mask: [b]0x1fe8[/b]
GPIO_I2C_Clk_Mask_Shift: 0x0
GPIO_I2C_Data_Mask: 0x1fe8
GPIO_I2C_Data_Mask_Shift: 0x8
I2C bus "RHD I2C line 5" initialized.

when

0x1f90 ----> i2cid:90 (VGA)

0x1f94 ----> i2cid:94 (HDMI)

then

0x1f98 or 0x1f88 or 0x1fc4 or 0x1fe8 can be LVDS. Right?

 

Are accepted tips or denials.

mucha we need someone to insert the values I need into the ati.c of TRUNK/KABYL. I don't know if we need only dual link but it would be a nice start. I dont know how it could be put in the first section of trunk (where TMDSA/:wub: names are, but it does seem simper on the KABYL section. In the kabyl there are also some disabled checks and values.

Thank you. However, somehow, RadeonHD doesn't detect the monitor connected to HDMI port & I presume that it also failed to extract correct EDID from internal LCD:-

As you can see - "Mapping DIG1 encoder to KLDSKP_UNIPHYE" - only LVDS is got mapped while HDMI is not.

 

Honestly, at this point, I don't know how to get LVDS working but if you want to continue testing, please see below.

 

Can you provide:-

1) Get EDID value in Windows by using a software called "MonInfo". The "Raw data" is EDID value:-

edid.jpg

2) Please try this connectors table with Shrike framebuffer. Please test this without any external monitor plugged in. I change the LVDS link a little bit, telling it to use DUAL_LINK:-

CRTC0 > DIG1 > UNIPHY_EF > LVDS: Encoder=0x00 Transmitter=0x02

--> 00000000 02 00 00 00 40 00 00 00 09 01 00 00 02 00 00 07 (LVDS)

--> 00000020 00 08 00 00 00 02 00 00 00 01 00 00 10 01 02 02 (HDMI)

Offset of Shrike connections table (3 connections):-

  • 32bit: 0x00037298
  • 64bit: 0x00010F80

 

The extracted EDID value is

"4CA34B540000000000130103902615780A56259D5B539A2817505400000001010101010101010101010101010101A525408860841630302015007ED71000001AA525408860841630302015007ED71000001A000000FE004A31334A58803137334B540A200000000000000000000000000002010A20200002"

Hello all! Help me please with my video card ATI Radeon Mobility 4570 512 mb on ASUS k40ad. I read the manual but did not quite understand it works. Apparently this is due to lack of knowledge and experience. What should I do first? I'll be very grateful for your help!

you are right the ATY,EFIDISPALY reported by the ioreg dump is injected by chameleon bootloader Not detected by the drivers & only cosmetic

 

but as he reported :

 

TMDS-A (HDMI-A & Single Link DVI) are Single Link,

TMDS-B (HDMI-B & Dual Link DVI) are Dual Link,

LVDS is Single Link, but for some High Resolution Internal LCD is Dual Link.

Yes, I know. I just let everyone know that I already experiment the ATY,EFIDisplay injection in the ati.c (chameleon). So that no one waste their time trying the same thing. The injection only cosmetic.

What resolution do you have on your display? And mucha's one?

On my Dell Studio 1557, it has a dual-link LVDS transmitter and can support up to WUXGA panel resolution (1920x1280). But right now it only fitted with WXGA panel resolution (1366x768). I can upgrade anytime to Full HD LCD panel (1920x1280) since it already have dual-link LVDS transmitter.

 

Any Dell Studio notebooks, including Studio 1747 (almuras), SXPS 1640 (sydlix) & SXPS 1645 (jvilla), also has dual-link LVDS transmitter. I got all three of RadeonHD's log from them & I found all three have Full HD LCD panel. So far they unable to get LVDS working. Also RadeonHD's log said all three have single-link LVDS transmitter which is weird. Based on the notebooks specification, it should be dual-link LVDS transmitter.

 

@Mucha, does your notebook have single or dual-link LVDS transmitter (hardware specification)?

Is this internal LCD's EDID? I'll prepare the display overrides for you later.

Yes, it is internal LCD's EDID.

 

Please try this connectors table with Shrike framebuffer. Please test this without any external monitor plugged in. I change the LVDS link a little bit, telling it to use DUAL_LINK:-

CRTC0 > DIG1 > UNIPHY_EF > LVDS: Encoder=0x00 Transmitter=0x02

--> 00000000 02 00 00 00 40 00 00 00 09 01 00 00 02 00 00 07 (LVDS)

--> 00000020 00 08 00 00 00 02 00 00 00 01 00 00 10 01 02 02 (HDMI)

 

I tried these connectors, only HDMI is working, VGA and internal LCD have black screens (I think they are detected though)

not sure about it, i know my screen is 1366x768 (doesn't need a dual-link) & AMD website says Mobility Radeon 4600 Series support dual channel LVDS

I suggest to open another thread that should be reserved only for Working System logs (no commentary allowed, only systems logs & for woking configurations only) to keep it clean & usefull,

just to help us getting feed-back informations that may help to figure the working combinations & mapping

 

the proposed template is:

 

1- System identification: HP Pavilion DV6-1240ek - ATI Mobility Radeon 4650 (DeviceID:0x9480) - Max screen resolution: 1366x768.

 

2- bcc9 RadeonDump log:

also I have a Sony Vaio (VGN-NW21EF) but it lacks the i2cid of LVDS

It's interesting, could you upload the file of RadeonHD's log?

On my Dell Studio 1557, it has a dual-link LVDS transmitter and can support up to WUXGA panel resolution (1920x1280). But right now it only fitted with WXGA panel resolution (1366x768). I can upgrade anytime to Full HD LCD panel (1920x1280) since it already have dual-link LVDS transmitter.

 

Any Dell Studio notebooks, including Studio 1747 (almuras), SXPS 1640 (sydlix) & SXPS 1645 (jvilla), also has dual-link LVDS transmitter. I got all three of RadeonHD's log from them & I found all three have Full HD LCD panel. So far they unable to get LVDS working. Also RadeonHD's log said all three have single-link LVDS transmitter which is weird. Based on the notebooks specification, it should be dual-link LVDS transmitter.

 

@Mucha, does your notebook have single or dual-link LVDS transmitter (hardware specification)?

Where do you see on RadeonHD log that our lvds is detected as single link? Do you have the full radeondump log to show us?

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

 

 

I am sorry but what the difference between internal and clamshell? When should I choose one or the other?

 

Thanks,

almuras

This is your radeondump's log:-

See? LCD panel (LVDS) is using UNIPHYE transmitter (UNIPHY2:LINKA).

I know we are discussing this on the other thread.

 

But mine also says UNIPHYE, but I get no output with single link only with dual link.

Further, you said my screen resolution requires dual link.

I don't think we have entirely figured this out yet.

also I have a Sony Vaio (VGN-NW21EF) but it lacks the i2cid of LVDS

i have attached my encoder.txt

This is the important part from the encoder.txt:-

Mapping DIG1 encoder to KLDSKP_UNIPHYE

CRTC1 > DIG2 > UNIPHYA > HDMI: Encoder=0x01 Transmitter=0x10

CRTC1 > DAC > DACA > VGA: Encoder=0x10 Transmitter=0x00

 

senseid = (i2cid And 0xF) + 1

LVDS: (? And 0xF) + 1 = ?

VGA: (90 And 0xF) + 1 = 1

HDMI: (94 And 0xF) + 1 = 5

 

Please try senseid 0 for LVDS.

 

Shrike framebuffer (32bit):-

Shrike framebuffer (64bit):-

--> 00010F80	 02  00  00  00  40  00  00  00  09  01  00  00  12  00  00  00 	(LVDS)
--> 00010F90	 10  00  00  00  10  00  00  00  00  01  00  00  00  10  01  01 	(VGA)
--> 00010FA0	 00  08  00  00  00  02  00  00  00  01  00  00  10  01  02  05 	(HDMI)

 

Please test & let me know the results. Probably you'll need to inject EDID for your LVDS but just try the above first.

 

(P/S: I'm not confident LVDS will work on Sony VAIO. I know Sony VAIO have known issue with LVDS.)
