Does SMCProcessor and SMCSuperIO work for us, I tried it and I don't see anything load are they meant for Laptops?

SMCProcessor and SMCSuperIO

• SMCProcessor implements temperature monitoring for Penryn CPUs or newer
• SMCSuperIO implements support fans reading

Another probably stupid question: I run my build with cascade lake 10940x cpu. Should I anyway use TSCAdjustReset.kext? I’m still studying the basys of the OC configuration and I read that this kext was initially written for Skylake X CPUs and so I had the doubt...

Yes, you should continue to use it and change the IOCPUNumber to 27; 14x2-1=27.

Can you share your system DSDT ?

I have 2 ongoing problems with my ASUS X299 Sage 10G Catalina 10.15.6 MacPro7,1 hack:

1. Kernel panics/crashes (multiple times daily) which can cause seemingly random reboots anytime, but seemingly more often when the display is asleep (the computer is not asleep). (Some of the error reports downloaded below). I asked about this in the past, back in June-July 2020 here and is discussed a bit there as well with @JimmyS & @macmaxxx See here: #790 -- most of the reboots/crashes/panics seem to be "userspace watchdog timeout: no successful checkins from com.apple.WindowServer." Any ideas?

2. Problems getting my Thunderbolt devices to be visible & available after a cold boot or a reboot. Thankfully, hot-plugging works, but hot-plugging seems to be required now after every boot. If I do an unplug-replug, all of the devices become available. This is a pain, especially when combined with problem #1 above, as every time I reboot, I lose my Thunderbolt RAID drives and my audio interface. Any idea on how to fix or workaround? Is there a way to perform the function of an unplug/replug in the software without actually physically unplugging and plugging back in? That might be a reasonable workaround that I can do if I have to restart the drives remotely.

I built an ASUS X299 Sage 10G Catalina 10.15.6 MacPro7,1 System in June using BASE-EFI @djlild7hina's Github page and his personal help with TB3 and USB SSDTs (thanks @djlild7hina and thanks to @Loloflatsix for continuing the effort!), so, there should not be any surprises. This week, I did update the BIOS to version 3203 with the Apple Logo (the version I found from @izo1 on this page - #2,673) without much change. Everything is still working ok without major problems (other than above) and without any improvements since I updated the BIOS. I am including relevant files in case someone has some time to try to help me diagnose my issues. Thanks in advance!

Exported from hackentool? Give me a bit I’ll be home from the hardware shortly.

Just open MaciASL app, it will open your system DSDT and save it as DSDTosxfr33k.aml ( not dsl scroll the arrow down)

Here is an EFI adapted from yours above:
- new SSDT-X299-TB3HP with the same name ( XCH4 section according to USB.kext see below)
- added SSDT-VEGA64
- assed SSDT-X299-XHC (XHC2 / XHC3 section according to USB.kext see below)
- changed SSDT-RTC0 (for new bios)
- new USBASUSX299SAGE.kext ( only match with MacPro 7,1) : with XHC2 / XHC3 / XHC4 section added , XHCI unchanged)
I checked it but it's late here...
Try it with an USB stick and attach your IOREg
