Last month Intel’s open-source Linux software engineers began sending out Xe3P_LPD display support in preparation for display capabilities with Nova Lake. Now being built out atop that is further functionality with the most recent talking point being DisplayPort 2.1 Advanced Link Power Management (ALPM).
The new Intel Linux kernel graphics driver patch series is simple and straight to the point:
“ALPM support added on DP2.1 and xe3p will support DP2.1 alpm.
This patch series extending alpm supoort for DP2.1.”
Intel Xe3P will support DisplayPort 2.1’s Advanced Link Power Management. ALPM is a feature for fast wake and fast sleep of a sink device in the name of power savings. ALPM has been more common in eDP laptop displays. Earlier this year the Intel Linux driver began more plumbing around ALPM and another feautre: LOBF for Link-Off Between Frames. It’s also just been recently too that the AMD graphics driver added eDP ALPM support for this added power savings during periods of inactivity.
This patch series is working through the ALPM support for Xe3P graphics on Linux. Nothing else to really note for end-users from that patch series besides that DP 2.1 power-savings feature will indeed be supported with future Xe3P hardware.
