120hz patch no longer functions on Monterey 12.4 #4

Closed FabianPonce closed 2 years ago

I'm not sure if this repo is still maintained but this is the most detailed source of information I've found regarding the bandwidth limitations for high-refresh rate monitors.

I tried to rebuild the patch by working my way through the symbols and I've found __ZN35AMDRadeonX6000_AmdRadeonFramebuffer39validateDirtyDisplayPathTimingBandwidthERh, but I can't seem to find anything that would relate to the bandwidth in kbps.

I did try to wrap this function in WEG myself and have it return kIOReturnSuccess, but that just made my system not boot.

I'm still digging into this and the other AMD kexts but I thought you might know more. :-)

Sorry, I'm preparing my exam recently so I have no time to handle this. Perhaps I will look into it 2 or 3 months later.

Hi, I suppose you can use tool SwitchResX to get 120hz working without any WEG patches. Try using my custom resolution configuration in SwitchResX. I'm currently running Monterey with 120hz working without any patches.

Meanwhile, if you want to go the patch way. You can try to see the panic log to figure out why your code does not work. And Monterey has removed the function symbol in AMDRadeonX6000Framebuffer.kext. So you have to call some C-style functions by address. See https://github.com/acidanthera/WhateverGreen/pull/90#issuecomment-1173372092 for more detail.

Yes, I use this configuration for my Alienware laptop which uses eDP connected the graphic card to the internal 4k 120hz screen. But I don't know the exact version of this DP connection.
