Add Navi 40+ support

[simonpm]

macOS Version

Sequoia

What is your CPU's model?

AMD Ryzen 3700X

What is your GPU's model?

AMD Radeon 9060 XT

Please describe the feature in detail.

This is likely a long shot or not possible right now, but I would like to request support for the latest AMD GPUs (e.g. 9060 XT).

What alternatives have you tried, if any?

Currently device is not supported. Cannot proceed with installation of OSX

I will do it for one trillion dollars.

I will do it for one trillion dollars.

Where do we pay

[VisualEhrmanntraut]

in the sponsor section at the main page

Thank you! While I don't have that kind of cash, I am happy to contribute to this project, including downloading any firmware, contributing to the project code. I suspect this will require full re-implementation of the hardware abstraction, but am not sure where to even begin, but I am eager to learn!

[simonpm]

I have generated a .patch file outlining changes with the assumption that Navi 23 will suffice...will be testing shortly. Would truly appreciate you having a look.
Edit: minor edit to the patchfile

NootRX-Navi44_Rx9060XT.patch

lmao

[simonpm]

not sure I understand your answer. I agree, this was a feeble attempt. When you have some time, could you elaborate what would be most helpful?

I am having some trouble compiling (incompatible XCode version on old Mac), but once I get that sorted, I will test.

As a bit of an update, with many more modifications to the patch, including vbios, and patched AMDRadeonX6000*.kexts, I am able to boot into installer spoofing 9060XT as 6000 series card, and gui works to allow to begin installation. After 1st reboot during install, the process will continue. After 2nd reboot, it goes into restart loop. Likely because those same AMDRadeonX6000*.kexts need to be now injected into the installed system extensions. Still working on this.

PLEASE NOTE: There is still tons to figure out to get this working and working well. I don't yet have a viable solution.

[VisualEhrmanntraut]

not crashing doesn't mean working. and if you continue giving false hope to people I will block you from the org

[simonpm]

such a great point! Gosh, that was never my intention. I will make my earlier post clearer...I am not anywhere near a workable solution

Update 2: Have finally managed to finish the Sequoia install and the OSX is consistently booting to userland. However, while GPU only shows 14MB VRAM and there is no acceleration. So, there is still lots to sort out. Feel like this may not work at all...

Where I feel I am stuck is extracting the relevant files from the VROM with psptool (e.g. psp_key_database, psp_sys_drv). Although the VideoRom file is exactly 2MB, it keeps crashing complaining about the file size not being exactly what it is looking for. Tried trimming it but to no avail.

Would really appreciate some pointers.

I'll give you a hint: open the TechPowerUp page for Navi 23, and then one for Navi 4x, and look at the DCN version.

Update 3: Thanks [VisualEhrmanntraut] this is exactly what I needed. I was successful in extracting the relevant firmware files with some creativity. The below is the .patch to date. Still working on this.
Issue: during boot, SYSLOG/IOLog confirms all steps are completed (e.g. bin files are loaded, AMD kexts injected), but OS X GUI does not render (running on Sequoia).

Any suggestions on further troubleshooting I can do?
