Possible easy fix for AMD RX 480 in Sierra using FakeSMCkext.

Status
Not open for further replies.
Ok, got acceleration on Nitro+ OC RX 480 8GB setting intel as primary in BIOS, but i really think this method only help to get ports recognized well.

I don't remember how to dump FB port config, but i can do some tests if someone can help on how to do this.

Also, the more I think about it, your conclusion makes sense. Whenever I boot with PCIe selected as primary, I get "No Signal" on my screen. Hence it does seem to be a problem with ports rather than anything else.

EDIT: For reference, this is what my dump looks like:

Ok that link is an entire bible, written in phoenician for me, but i'll give a try.
 
Ok, i has to search the proper version of ati-personality.pl that works in sierra. Mi card have 5 ports: 2dP, 2 HDMI, 1 DVI-S

So, according to the guide, i have to work with the 5 port's FB, which are (dumped by me with ati-personality):

What i missing or doing wrong here? There isn't the BAFFIN FB on ati-personality.pl results, so why everyone are working with it?

I'm on 12.3 public beta 1, DCPImanager says it working with DAYMAN FB


Anyway, i'm working on the next step, i'll post the results
 
Ok, i tried with no results.
Here is what i done:

First, dumped bios with DPCI Manager and dumped the bios files with radeon and redsock decoders.

So, changed to PCIe in BIOS and

1. Without ATIinject in clover: Signal loss
2. Injected OPM ports 05: With hdmi connected singal loss, with dP to VGA adapter signal hangs (i tried volume buttons but no sound)
3. Injected Dayman (that was before this patch, using it with the IGPU+PCIe method): same result as 2.

Maybe i should try with another framebuffer? maybe i should patch the kext directly?

I'll try

There is only one framebuffer to edit:
Berbice: macbookpro 15 (2.5k internal, 2x 5k)
Florin/Exmoor: imac 27 (5k internal, 2x 5k)
Guariba/Dayman: 4x DP, HDMI, DVI
Baladi: 6 DP

Suggest: Try Guariba/Dayman/Baladi; if working, map framebuffer connector to physical connector. If not working, one display/one physical connector each boot (note IOReg/port to physical connector)
Mapping makes it easier to determine required edits
Reply with results.

Edited/imac framebuffers, experiments

I started with OPM with no results

I have only one display (1920x1080) with VGA and HDMI ports, so i can only test with HDMI to HDMI and dp to VGA adapter, and also with no results

I've setted imac14,2 in SMBIOS

Did you see my ports mapping? are that well done?

No idea. Moving 01 in the middle of the connector is not correct. If OPM/Port 0x0 was working, there would be no need to edit it. It is very important to find the framebuffer connectors that work natively. Suggest obtaining DP2HDMI and DVI2HDMI adapters to enable all physical connectors with your HDMI display.
