ahmed_ais Posted May 30, 2016 Author Share Posted May 30, 2016 eDP + nVidia is hard very hard same on my system. your issue is eDP with nVidia , not about SLi nVidia. if your system is LVDS i think it work perfect. dGPU for internal Display, untrabay GPU for external display. Unfortunately, I made myself so sure that it is eDP: I have also checked your topic here about eDP and K1100M and I hope you get proper help for your issue. But our status is so far far away than yours as we don't have QE/CI yet no matter what we tried. Do you suggest anything I could try? Thanks.

Thanks. try this : boot with defaut dsdt ssdt --> got black screen -> use share screen or teamview to check ---> i think is QE/CI but no display plug in <----- because display don't have power aux <---- inject aux ---> got full QE/CI but dark screen. thanks for your ioreg of real mac on this topic. i think we need inject display for break this issue.

I believe the first step is to figure out how to boot without that flag. Link to comment Share on other sites More sharing options...

ahmed_ais Posted June 9, 2016 Author Share Posted June 9, 2016 oh i see some comment was lost have any news? @ahmed_ais Yea that's unfortunate. In summary, I tried to make EFI strings for both cards as you suggested; the internal at PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0) and the external at PciRoot(0x0)/Pci(0x7,0x0)/Pci(0x0,0x0) and used the resulting hex through Clover but it changed nothing (i.e, I still can only boot with nv_disable=1 with or without the web driver, no QE/CI, and display is not defined as built-in). While preparing the EFI strings I failed to create the NVCAP strings using NVCAP maker and I don't know why but the tool did not produce any code when I select either roms for the built-in or external gpus so I set NVCAP to one of the default options available. Here you will find both the EFI string plist and the roms for both gpus in case you might want to try calculating NVCAP. Link to comment Share on other sites More sharing options...

AUX and hotplu was inject on efi signal link ----- you can read the real retima mac ioreg... i'm try but not work, may be your system can be work.

ahmed_ais Posted June 10, 2016 Author Share Posted June 10, 2016 hmm.... + my idea efi string for enable dual VGA. not for enable QE/CI Would you clarify what you mean by "enabling"? Do you mean booting with both cards on without nv_disable? because, at the moment, I can boot and see both GPUs in IOREG but of course with nv_disable=1 so drivers are not initialized. This is from a previous setup (as I'm using Windows now): about without nv_disable and QE/CI try this efi with out nv_disable https://dl.dropboxusercontent.com/content_link/Rpgoo4ipM09Ji9ZdLAQeedVRATAqQqQdyuK2PVG3uc42CuVeO2UEpEbXLKYoObLg/file?dl=1 display can turn on with blacklight but may be no signal (dard screen) File not found, kindly update the link.

Thanks your "enable" is false. false on fakeID of nvidia. you can see vendor id : 0x0FE4 <---- that's device iD , is not vendor id. it's mean NVDA kext neva load same as nv_disable=1; file: EFI_STRING.plist.zip Link to comment Share on other sites More sharing options...

I have applied the EFI String you posted (without nv_disable flag) and the boot process stuck at a point without reboot or KP. Here is the final screen before it stop: http://i.imgur.com/mpUzW5w.jpg.

EDIT: I can see that the external GPU is not affected at all with the injection. Isn't this what you wanted to achieve? I tried the web driver to see if there is any difference. Booting (without nv_disable and with nvda_drv) halt after loading the driver but it does not reboot or KB. Booting (with nv_disable and with nvda_drv) reach desktop but with glitchy graphics as expected although I feel the desktop experience is a bit better with the web drivers. I'm going to see if there a way to disable the external GPU via ACPI. efi_str2-nv_disable_1.ioreg.zip Link to comment Share on other sites More sharing options...

ahmed_ais Posted June 20, 2016 Author Share Posted June 20, 2016 ... and ... dose it working ? Not sure what you mean but if you are referring to the dual GPU under Linux then yes it does. Otherwise, if you are referring to disabling the external GPU via ACPI then your suggested method did not work unfortunately. I also tried the following (without a method) just after the _ADR method but again it did not work either and the external GPU is still loaded.

I take it you mean eDP that support 75Hz refresh rate or those equipped with G-Sync? It would be great news for other people but unfortunately not with Y510p since it's refresh rate max is 60 and it lack G-Sync.

artas182x01 Posted December 30, 2016 Share Posted December 30, 2016 Hi!. I installed Web driver to OS X and I used VNC to check how card is recognised. While 2nd card is recongnised as it should, the first is called NVIDIA Chip Model with 256MB VRAM. Screen is seen as internal (to my surprise) with max resolution 1280x1024.

Maybe we need to use EFI string or somewhat. Wysłane z iPhone za pomocą Tapatalk The second card used to work fine since Yosemite but the problem has always been getting the first one connected to the display and being recognized as built-in. My previous investigations led me to conclude that IGD (Intel Graphics Display) does not completely go out of the scene even with two dedicated GPUs are on. That is, IGD is the only graphics device directly connected to the display and while the two Nvidia GPUs are active IGD fades out but still responsible (alone) to deliver all the processed graphics to the display. This behavior may be fine in Windows and Linux as the driver knows how to deal with it ignoring that gateway (IGD) but it is not the case for macOS where this setup just does not exist (for real macs) and the driver is not aware of it. So with 2 Nvidia GPUs --> IGD fades out (to be a gateway only) --> macOS see the 2 GPU's --> macOS cannot see the display (only a gateway) --> macOS assume the gateway is the display for the system (which is not exactly true) --> configurations for 1st Nvidia with display fails --> macOS does not work correctly graphics wise. This is all a theory and could be completely wrong (I hope). For that, I'm reading into how IGD work with Optimus (how the connections are designed). I wish if there were any technical manual for this type of gaming PCs where the details of the hardware are shown. Link to comment Share on other sites More sharing options...
