The Linux 6.10 kernel is poised to remove support for old DEC Alpha EV5 platforms and earlier.
The modular/upgradeable Framework Laptops employ an open-source embedded controller (EC) firmware derived from Google's Chrome OS EC project. This is great for open-source fans and allows re-using much of the same Chrome OS EC software support that already exists. But there is also vendor-specific commands supported by the Framework Laptop EC and thus a dedicated Linux kernel driver is now being worked on for handling those vendor/device-specific features.
Cirrus engineers have seen a number of patches queued into the Linux sound subsystem's "for-next" branch for enabling audio support on some new laptops with the upcoming Linux 6.10 kernel cycle.

Right now for buggy HID hardware or other input devices not exactly aligning to specs or having known hardware workarounds required, a new Linux kernel driver tends to be needed or at least quirks to be added to existing kernel driver code. There's no shortage of wonky HID hardware/drivers out there to deal with such odd cases. Due to the lengthy kernel cycles and other factors involved, leveraging (e)BPF has long been talked about as one of the areas where it may make sense for being able to more quickly send out hardware support fixes in the form of eBPF programs. The Rust-written udev-hid-bpf project is ready to help in that enabling effort.
