Things are evolving fast… Now just a boot argument:

@Shaneee Can you merge Casey's kernel patches with masking? I want to PR to Dortania to remove the warning about MSI boards, but it would be preferred if the patch would be fully finished. It's beyond me tbh. I tried it earlier and the patch wasn't found each time.

Has a Pandoras Box been opened?. CaseySJ's well documented posts during testing (I'm a visual learner), has also resulted in a MSI 570 board being tosh'd with a screenshot to prove it. I read a note is being composed to send to the OpenCore guys.

Rather a problem solved with AMD platform because MSI X570 boards already had issues with PCIe devices not being properly initialised, and @CaseySJ serendipitously fixed it with his work on X670.
So one back in the box. "Garbled audio" and "no VT-d" remain outstanding.

The pull request for the patches may well be withdrawn if testing confirms that boot argument 'pci=0x8000000' solves the issue.

It's strange, to me the word 'boot argument' doesn't really justify the work and drive that CaseySJ put in!. If confirmed, adding 'pci=0x8000000' to your EFI is a simple procedure, but it doesn't explain everything that's happened behind the scenes to reach that point.

Why? Do you think that kernel patches would be some more dignified result to show for CaseySJ's work?

Not at all!, I get restaurants started so coding isn’t my thing. But to a layman like me who doesn’t really understand code, the amount of testing that CaseySJ put in and just the sheer doggedness of solving a problem such as AM5 and to distill it down to a boot-arg is quite astonishing to me, but what would I know!.

A kernel patch shows a unique discovery being made. A boot argument does not. You are right that a boot argument hides the work that went into figuring it out.

But that’s okay! We know.

Seems our Method 3 kernel patch may be even better than the boot argument. Hence we're going to add it to the amd-osx patch list on GitHub.

• Method 3 patch allows 8-bit extended tag fields (ETFs) to be enabled, and only disables 10-bit ETFs.
• Boot Argument disables both 8-bit and 10-bit ETFs.

Audio stuttering problem on AM5 platform with Zen 4 has just been solved by @Shaneee!

If it performs better with correct values reported as it should then you could try merging into OC and building to test, Check here, https://github.com/CloverHackyColor/CloverBootloader/blob/master/rEFIt_UEFI/Platform/cpu.cpp#L960
