Linux 7.2 Released: Cache-aware scheduling, sub-schedulers, and Raspberry Pi GPU power management
Linux 7.2 was tagged and released this week, one of the busiest cycles ever, only beaten by 6.7. Highlights include cache-aware scheduling, improvements to MGLRU, the concept of sub-schedulers for sched_ext, and automatic creation of multi-size transparent hugepages. Igalia contributed the DRM scheduler fair policy, which is opt-in due to a last-minute regression, and runtime power management for Raspberry Pi 4 and 5 GPUs, reducing idle power consumption. The kernel also fixes a 14-year-old futex bug and improves sched_ext observability.
With Runtime PM, the GPU is powered only when it is actually processing work, and its clock can be disabled while the GPU is idle.

Does anyone understand how HDMI 2.1 support is now no problem? I remember that 2.1 support in AMD's open source driver was blocked by the HDMI forum, but I haven't heard any news about them unblocking it. What changed?

What about this is more interesting than the LWN coverage?

Who is the main audience for this type of content? Genuinely curious because I am not a serious Linux user.
What type of info do you get out of this for those who read this?
So i can glance your insight?

I clicked this one with no hype. I am now exited to update the kernel of my raspberry pi 4.

Okay, so ELI 5 why I would now use HDMI instead of DP?
All my monitors support DP, my GPU has more ports for DP ...
I am genuinely interested as I've never even considered using HDMI for my Desktop.
