7970 mysteries in 10.9.2.

khe91 · February 15, 2014

Hello Graphic Card Wizards,

I got a Asus MATRIX-HD7970-P-3GD5.

This card has 4 DP, 1 DVI-DL and 1 DVI port.

AS01U2.bin  :

In 10.9.1 it worked well with my 2 screens. A Dell 3011 connected via DP and Dell 3007 connected via DVI-DL, both 2560x1600.

No graphic inject or DSDT needed, OOB, LuxMark of 2298.

With all the 10.9.2 betas I can't get the same behavior.

A single screen via DVI-DL connected gives the same results as in 10.9.1, no injects needed, OOB, full 2560x1600, LuxMark of 2195.

But if I add a screen via DP or only connect one screen with DP then OSX reboots right away on graphic init.

So I started with Clover ATI Graphic Inject Yes.

Same reboots on graphic init.

After a while I connected a third screen to the DVI-SL port.

From then on 10.9.2. boot to the Workspace.

Clover defaults to the Futomaki framebuffer, with that fb DP is working, DVI-DL no picture, LuxMark 2191.

Then I tested all the framebuffers:

Chutoro, Ebi, Gari: DP not working, DVI-DL max resolution 1280x800.

IkuraS, KaniS, MaguroS: DP working, DVI-DL max resolution 1280x800, LuxMark 1355
Junsai: DP working, DVI-DL max resolution 1280x800, LuxMark 2183

DashimakiS,OPM: DP not working, DVI-DL not working, DVI ok

Hamachi, Aji: DP working, DVI-DL not working, DVI gives VGA signals, LuxMark 2201

Buri: no screen on any connector working

best result seams Junsai LuxMark ok, DP is working, but just 1280x800 on the DVI-DL port.

I tried iMac14,2 and MacPro6,1 smbios, PCIRoot=1 and PCIRoot=0, Clover Duallink 0 and 1.

What else could I try to get full 2560x1600 on the DVI-DL port like in 10.9.1. ?

Is there a DSDT or SSDT injection for the 7970 and 10.9.2. ?

ati-personality.pl don't work anymore with 10.9.2. so I can't get the AMD7000Controller.kext framebuffers and ports.

Thanks,

khe91

iFIRE · February 15, 2014

easy, use the kexts from 10.9.1 :yes:

khe91 · February 15, 2014

AMD7000Controller.kext from 10.9.1. don't work in 10.9.2., they don't even recognize the card anymore

And the 10.9.2. kext work as long only one screen is connected with DVI-DL.

Problems start if DP is used.

So the question is what happen inside AMD7000Controller.kext if a screen with DP is connected ?

khe91 · February 16, 2014

Found something else:

If I use the HD4600 as first display then 7970 works also OOB in 10.9.2. without any injections from Clover.

If I connect a DP screen to the 7970 then the reboots are back.

So at the moment my 7970 is like the second D700 in MacPro6.1. First graphic card is HD4600 with 2 screens 2560x1600 via DP and the 7970 doing all the OpenCL computing.

I believe it's all about the display connector settings in the new AMD7000Controller.kext of 10.9.2.

But I can't patch AMD7000Controller.kext of 10.9.2. because bcc24 ati-personality.pl script don't works with 10.9.2. anymore.

iFIRE · February 16, 2014

try app Framebuffer rotate and add in start app in user/account, because MAC OS X start with the integrate card hd4600 for boot, then the system switch to the PCI card

Problem is it reboots right away if a screen is connected via Displayport.

The reboot occurs before Workspace is open, so it never reaches the Login Items to start FBRotate.app.

Also as long no screen is connected with DP, then the 7970 is active, no need for rotate or sleep trick.

The DVI connectors work, but don't give full resolution, just 1280x800 instead of 2560x1600.

iFIRE · February 16, 2014

well, this sure is needed patch the Framebuffer, or try inject the card in the DSDT, and no other idea

khe91 · February 16, 2014

I'm trying to inject it in DSDT since several days ...

Injected GFX0, but it's always on the wrong position in ioreg (see screenshot), can't find the correct place in the DSDT behind the PCI bridges.

Position should be where display@0 is.

install the kext lspci.kext, then from the terminal app, lspci -nn

post here the result, you ioreg it is corrupt

I not sure, but this DSDT is from your machine ? because you don't have device PEG 030000, like this , try add device PEGP in PCIO, like for my card, see the photo

Device (PEGP)

{

Name (_ADR, 0x00030000) // _ADR: Address

03:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Tahiti XT [Radeon HD 7970/R9 280X] [1002:6798]

khe91 · February 17, 2014

After a change of the address to 0x0003000 there is no GFX0 at all in the IOReg anymore.

The address of the working HD4600

00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)

is 0x0002000

So change of PCI bus to 03 is maybe not 0x0003000

03:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Tahiti XT [Radeon HD 7970/R9 280X] [1002:6798]

If ATI injection in Clover is activated then it will work, is there any way to see what Clover is actually injecting ?

khe91 · February 17, 2014

There are some symbolic names for PCI bridges missing in the DSDT, as long there is no name for pci-bridge@10 from IOReg I can't inject GFX0 at the correct position.

GFX0 must be on the position display@0.

khe91 · February 21, 2014

Thanks to Toleda for helping out with the correct GFX0 position in the DSDT:

            Device (PEGP)
            {
                Name (_ADR, 0x00010000)  // _ADR: Address
                Method (_PRT, 0, NotSerialized)  // _PRT: PCI Routing Table
                {
                    If (PICM)
                    {
                        Return (AR02 ())
                    }


                    Return (PR02 ())
                }


                Device (PEGA)
                {
                    Name (_ADR, Zero)  // _ADR: Address
                    Device (PLX0)
                    {
                        Name (_ADR, 0x00100000)  // _ADR: Address
                        Device (GFX0)
                        {

and bcc9 for updating the ati-personality.pl script.

Still can't get the 7970 work with DP and DVI-DL. Posting some findings at Editing custom personalities for ATI Radeon HD[45]xxx - Page 36 - ATi - InsanelyMac Forum

@khe91 did you find a solution or make progress? I have a similar graphics card (Asus 7970 DirectCU II - HD7970-DC2T-3GD5) with 4x DP and 2x DVI (1x SL and 1x DL) just like you. :-)

Still no video sign in any DisplayPort of 7970.

Anyone can see any error here?

Progress!

Got 1x DP + 1x DVI-D @ 7970 at same time functional! :-)

Screen%20Shot%202014-03-06%20at%2012.24.

Screen%20Shot%202014-03-06%20at%2012.28.

But low score @ Luxmark.

Using Vervet framebuffer (ioreg | grep ATY get ATY,AMD,RadeonFramebuffer, so no framebuffer) with 1x monitor @ DVI-D 7970 and 1x monitor @ DP in CPU-VGA i get 2000+ points.

Any tips to get more juice from VGA when framebuffer is enable?

khe91 · March 6, 2014

You could try to edit the Junsai fb, there I got a better Luxmark, see post 1.

I give up with the 7970 and sold it.

I got this problem @ 10.9.1, you can try another connector, like DP.

Music Producer · March 6, 2014

Tried already, it's the last thing from me having an perfect hack. Wish I could fix it!!!

I REALY understand how you feel Sir. Best wishes with you new card.

Thx for Junsai tip, i will give a try.

pablos93 · March 7, 2014

It's fixed in 10.9.3 beta. My mini-DP port works again!

I'm using chameleon with the default Framebuffer.

junecaz · March 7, 2014

Get correct performance with edited Junsai framebuffer! But only one DP output works simultaneously with DVI-D (the unplug and plugin trick @ dvi is required to get 2560x1440).

Both monitors plugged in 7970 @ 2560x1440 and great performance (2000+ luxmark).

Well.. progress.. i think.

It's fixed in 10.9.3 beta. My mini-DP port works again!

Thats great news! Do you have multiple monitor setup? What resolutions?

pablos93 · March 7, 2014

Hey there! I've got 2 monitors, one @ 2560x1440 using the mini-DP out and another one @ 1024x1080 using the DVI out.

I'm glad they fixed it

7970 mysteries in 10.9.2.
