General

Tuning Intel Skylake and beyond for optimal performance and feature level support on Linux:

Note that on Skylake, Kabylake (and the now cancelled "Broxton") SKUs, functionality such as power saving, GPU scheduling and HDMI audio have been moved onto binary-only firmware, and as such, the GuC and the HuC blobs must be loaded at run-time to access this functionality.

Enabling GuC and HuC on Skylake and above requires a few extra parameters be passed to the kernel before boot.

Instructions provided for both Fedora and Ubuntu (including Debian):

Note that the firmware for these GPUs is often packaged by your distributor, and as such, you can confirm the firmware blob's availability by running:

	#Put this in Export-Chocolatey.ps1 file and run it:
	#.\Export-Chocolatey.ps1 > packages.config
	#You can install the packages using
	#choco install packages.config -y

	Write-Output "<?xml version=`"1.0`" encoding=`"utf-8`"?>"
	Write-Output "<packages>"
	choco list -lo -r -y \| % { " <package id=`"$($_.SubString(0, $_.IndexOf("\|")))`" version=`"$($_.SubString($_.IndexOf("\|") + 1))`" />" }
	Write-Output "</packages>"
