Intel Linux Graphics Firmware
GuC is designed to perform graphics workload scheduling on the various graphics parallel engines. In this scheduling model, host software submits work through one of the 256 graphics doorbells and this invokes the scheduling operation on the appropriate graphics engine. Scheduling operations include determining which workload to run next, submitting a workload to a command streamer, pre-empting existing workloads running on an engine, monitoring progress and notifying host software when work is done.
DMC provides additional graphics low-power idle states. It provides capability to save and restore display registers across these low-power states independently from the OS/Kernel.
HuC is designed to offload some of the media functions from the CPU to GPU. These include but are not limited to bitrate control, header parsing. For example in the case of bitrate control, driver invokes HuC in the beginning of each frame encoding pass, encode bitrate is adjusted by the calculation done by HuC. Both the HuC hardware and the encode hardcode reside in GPU. Using HuC will save unnecessary CPU-GPU synchronization.

$ tar xf filename.tar.bz2
$ cd filename
$ vim install.sh #check variables, mainly if you are in Android environment where you might need to edit the Linux Firmware Directory.
$ sudo bash ./install.sh
Warning: The below script not only copies the firmware onto your system it will also try to make a copy of your existing initramfs image and will generate a new one. This might be helpful in the case your system fails to boot properly following the reboot after installation of the firmware.
1. Q: If I don't have any of the platforms listed in the table above, do I still need the firmware at all?
