Intel Kernel Graphics Driver Brings Panel Replay Tunneling For Linux 7.2
Now that the Linux v7.1 merge window is well past, Intel kernel graphics driver engineers are busy prepping new feature code for introduction for targeting the Linux 7.2 kernel this summer.
Already in preparation for the Linux 7.2 cycle in DRM-Next are more Intel Crescent Island enablement code for that enterprise-targeted AI inference accelerator. This week a drm-intel-next pull has more Intel Direct Rendering Manager driver changes ready for queuing ahead of Linux 7.2.
One of the notable changes with this week's pull is a Panel Replay bandwidth optimization. In particular, a patch worked on the past few months for enabling the Panel Replay Tunneling feature that allows unused bandwidth to be used by external display agents during idle periods with the link on for DisplayPort 2.0+ interfaces. Panel Replay itself is the partial self-update method of only transmitting updated portions of the screen contents between video frames in order to conserve bandwidth and more energy efficient behavior.
This week's drm-intel-next pull also has some other display fixes, integrating the DRM sharpness filter properly into the display scaler, restructuring DP/HDMI sink format handling, and other display-related changes like additional handling around Adaptive Sync Secondary Data Packet (SDP).
See this pull request for the full list of Intel DRM driver patches sent out as part of this latest pull request ultimately targeting the Linux 7.2 cycle.
