While the Broadcom V3D driver has been part of the mainline kernel for supporting the graphics found on recent Raspberry Pi boards, currently it doesn't support run-time power management. The lack of runtime PM has meant the GPU clock remains at full-speed even while idle.

One of the leading rare complaints over the Raspberry Pi 5 single board computer (and the more recently launched Raspberry Pi 500) is that it tops out at just 8GB of system memory... 8GB was enough years ago and still is if planning to use the Raspberry Pi for lightweight desktop and embedded scenarios and other situations where you don't need too much RAM for the four ARM cores, but for those wanting more, today the Raspberry Pi 5 16GB is being introduced.
The latest work that Raspberry Pi is working to upstream to the mainline Linux kernel is a HEVC/H.265 video decode driver that works on Raspberry Pi 4 and Raspberry Pi 5 single board computers.

A nice improvement is on the way for the Raspberry Pi graphics driver.
For months there has been talk and speculations around Raspberry Pi working to release a Compute Module 5 (CM5) in putting the power of last year's Raspberry Pi 5 into the small form factor for various embedded/industrial applications. It's pretty much a given that the Compute Module 5 will come, it's just a matter of when. With recent activity by Canonical engineers working on Ubuntu Linux, it's looking like the CM5 could be here soon.
While C tends to be the go-to launguage for microcontrollers, Raspberry Pi is promoting the prospects of using Rust on their RP2350 microcontroller.
Andrea della Porta of SUSE has been working on upstreaming the Linux kernel support to boot the Raspberry Pi 5 on a mainline kernel.
