Mehrab Posted March 17, 2017 Share Posted March 17, 2017 Hey, I am trying to inject my DSDT.aml with the AMD patch found here: http://www.insanelymac.com/forum/topic/312582-amd-polaris-ids-on-1012-sierra/ I found my GFX0 string in the DSDT file, however every time I compile I get the error 6084 DTGP Object does not exist (Using MaciASL) I was wondering if anyone had a solution for this? or could inject my DSDT.aml file? Thank you. DSDT.aml.zip Link to comment Share on other sites More sharing options...

Mehrab Posted March 17, 2017 Author Share Posted March 17, 2017 Im trying to get acceleration for my RX480 on my Hackintosh May I ask, what the problem was ? Why wasn't I able to compile it? Looks like now I am getting this error at boot when I use my DSDT file Link to comment Share on other sites More sharing options...

Mehrab Posted March 17, 2017 Author Share Posted March 17, 2017 Finally got it working. Reverted back to my original dsdt file then changed the amdradeon4100.kext file plist. Just added my PCI match key and it worked. Link to comment Share on other sites More sharing options...

Mork vom Ork Posted March 17, 2017 Share Posted March 17, 2017 Mehrab, may i ask what kind of board you are using? And did you make it work without the use of any helper card, like IGPU or any smaller AMD/NVIDIA card? Just patched your DSDT (like MaLd0n did it for you) and the patch of info.plist from AMDRadeonX4100.kext? EDIT: just answered the question myself by patching my DSDT same way MaLd0n did - and guess what? Right, it DOESN'T work w/o a helper card. But i don't give up. BTW: Framebuffer DAYMAN doesn't work anymore for a RX480. One have to use EXMOOR, BALADI or BERBICE (which i prefer for my Sapphire RX480 Nitro).

Im not sure I know the difference. And how would I go about doing this patch? Mehrab, may i ask what kind of board you are using? And did you make it work without the use of any helper card, like IGPU or any smaller AMD/NVIDIA card? Just patched your DSDT (like MaLd0n did it for you) and the patch of info.plist from AMDRadeonX4100.kext?

BTW: Framebuffer DAYMAN doesn't work anymore for a RX480. One have to use EXMOOR, BALADI or BERBICE (which i prefer for my Sapphire RX480 Nitro). Hey Mark, Im using the intergated GPU to boot. I have a Kaby Lake intel i5 with HD 630 graphics. Are you lacking a iGPU or compatible graphics card? Or do you want a single monitor display? For the latter, you can plug your iGPU into your monitors VGA and the RX480 into DVI port and switch sources after boot so you can navigate through the bios menu. I don't know if this helps but its all I know. I also read you can use FakeSMC for ATI in clover's boot config by setting it too something in the PCI Match keys, maybe that will work for you. I believe you can use 0x67EF1002 or 0x67FF1002 but double check it. Link to comment Share on other sites More sharing options...
okrasit Posted March 17, 2017 Share Posted March 17, 2017 Like so: #351 Also, you have to force the kext to load via clover. Link to comment Share on other sites More sharing options...

Mehrab Posted March 23, 2017 Author Share Posted March 23, 2017 Is there any information regarding the possibility of a RX480 driver that does not require a helper card? Link to comment Share on other sites More sharing options...
schot Posted June 12, 2017 Share Posted June 12, 2017 Is there any information regarding the possibility of a RX480 driver that does not require a helper card? No and there is also no solution for the new High Sierra, it will need a helper card or vbios mod (loose bios screen, clover screen and windows) Link to comment Share on other sites More sharing options...
jalavoui Posted November 11, 2021 Share Posted November 11, 2021 this also can be done using generic framebufer name ie let the driver detects it in this same I'm using only 3 frame buffers if I don't do this the amd8000 controller defaults to 5 Method (_DSM, 4, NotSerialized) // _DSM: Device-Specific Method { Store (Package (0x0A) { "hda-gfx", Buffer (0x0A) { "onboard-1" }, "@0,name", Buffer (0x1A) { "ATY,AMD,RadeonFramebuffer" }, "@1,name", Buffer (0x1A) { "ATY,AMD,RadeonFramebuffer" }, "@2,name", Buffer (0x1A) { "ATY,AMD,RadeonFramebuffer" }, "AAPL02,override-no-edid", Buffer (0x80) { /* 0000 */ 0x00, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0x00, /* 0008 */ 0x04, 0x69, 0xD5, 0x19, 0x9C, 0x75, 0x00, 0x00, /* 0010 */ 0x17, 0x14, 0x01, 0x03, 0x08, 0x29, 0x1A, 0x78, /* 0018 */ 0xEA, 0x85, 0x85, 0xA6, 0x57, 0x4A, 0x9C, 0x26, /* 0020 */ 0x12, 0x50, 0x54, 0xBF, 0xEF, 0x80, 0x71, 0x4F, /* 0028 */ 0x81, 0x00, 0x81, 0x0F, 0x81, 0x40, 0x81, 0x80, /* 0030 */ 0x95, 0x00, 0x95, 0x0F, 0x01, 0x01, 0x9A, 0x29, /* 0038 */ 0xA0, 0xD0, 0x51, 0x84, 0x22, 0x30, 0x50, 0x98, /* 0040 */ 0x36, 0x00, 0x98, 0xFF, 0x10, 0x00, 0x00, 0x1C, /* 0048 */ 0x00, 0x00, 0x00, 0xFD, 0x00, 0x37, 0x4B, 0x1E, /* 0050 */ 0x53, 0x0F, 0x00, 0x0A, 0x20, 0x20, 0x20, 0x20, /* 0058 */ 0x20, 0x20, 0x00, 0x00, 0x00, 0xFC, 0x00, 0x41, /* 0060 */ 0x53, 0x55, 0x53, 0x20, 0x56, 0x57, 0x31, 0x39, /* 0068 */ 0x33, 0x44, 0x0A, 0x20, 0x00, 0x00, 0x00, 0xFF, /* 0070 */ 0x00, 0x41, 0x36, 0x4C, 0x4D, 0x54, 0x46, 0x30, /* 0078 */ 0x33, 0x30, 0x31, 0x30, 0x38, 0x0A, 0x00, 0x06 } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } if u know that your card only uses 3 connectors u can fix a faulty edit this way also edit the amd8000controller (or any) and change this CFG_FB_LIMIT from 0 to 3 (like in this sample) this allows the driver to try to probe connections and in this setup injected a custom edit on connector #3 (VGA port) Link to comment Share on other sites More sharing options...
