INTEL --
This week marked Intel sending out initial Linux driver enablement patches for Alder Lake P mobile support to complement the existing Alder Lake S desktop support that has been coming together in recent months. In addition to the Linux kernel code for ADL-P, the Intel open-source Media Driver code was also updated for video acceleration on this Intel hybrid chip.

Alder Lake P open-source media acceleration support was merged this week into the GitHub repository for this video encode/decode implementation. Worth noting from that code drop is Alder Lake P having the same media capabilities / codec support as Alder Lake S and in turn the same as Tiger Lake and Rocket Lake Gen12 graphics.

That Tiger Lake / Rocket Lake / Alder Lake (P and S) support includes HEVC 12-bit decode and encode (and decode for 12-bit 4:2:2 and 4:4:4 content), decode for VP9 12-bit, and decode for AV1 8-bit and 10-bit content. The rest of the supported encode/decode combinations remain inline with prior Intel graphics generations. There is not yet any Intel accelerated video encode for AV1 and it doesn't appear that way through Alder Lake unless they have been holding back those patches.

That initial Intel ADL-P media driver support can be found via this commit though it's quite straight-forward in building off the existing Gen12/Xe code paths. In any case, great to see Intel continuing to provide punctual open-source Linux driver support well ahead of product launch.
