Z820 Big Sur SSDT-PM GEN

Hi!

I uploaded my HP Z820 from Mojave to Big Sur recently and I’m stuck in a major issue. Power Management SSDT generation! Also the CPU’s reach more than 70º sometimes, when so the system freezes and I have to hard-restart. I extracted the SSDT and DSDT files, copy them to my desktop and run ssdtPRGen.sh ; “ sudo ./ssdtPRGen.sh -a CPU0 -cpus 2 -mode custom -p ‘E5-2690’ -turbo 3800 “ ; I’m getting the following error over and over:

“ Warning: No ACPI Processor declarations found in DSDT! Using assumed scope (_SB) {}

Error: Processor name(s) not found… Aborting… Done. “

I hope somebody can help. Thanks!
