Intel added the Galois Field instruction set (GFNI) extensions to their Sunny Cove and Tremont cores. What’s particularly interesting is that GFNI is the only new SIMD extension that came with SSE and VEX/AVX encodings (in addition to EVEX/AVX512), to allow it to be supported on all future Intel cores, including those which don’t support AVX512 (such as the Atom line, as well as Celeron/Pentium branded “big” cores).
I suspect GFNI was aimed at accelerating SM4 encryption, however, one of the instructions can be used for many other purposes. The extension includes three instructions, but of particular interest here is the Affine Transformation (GF2P8AFFINEQB), aka bit-matrix multiply, instruction.
There have been various articles which discuss out-of-band
Windows Hotspot allows you to easily create an AP (Access Point) from your existing Wifi card. Many computers such as the ROG Ally have a variant of the MT7922 chipset which supports Wifi 6E and it can be used to create a high bandwidth P2P connection for game and VR streaming. Unfortunately, Windows does not provide much support for configuration of the AP channel and bandwidth. Fortunately, it is possible to change these from some registry entries. Note that you must reboot for the changes to take place.
The location of the registry key is inside HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class{4d36e972-e325-11ce-bfc1-08002be10318} and depends on the order the network devices are installed on your computer. For example, it is HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class{4d36e972-e325-11ce-bfc1-08002be10318}\0001 on the ROG Ally. Look at the data for value DriverDesc to confirm that you are in the right key.
