qemu 11 drops 32-bit host support: https://wiki.qemu.org/ChangeLog/11.0#Host_support_2

i guess my point with posting this is that the world is moving on. even alpine will eventually drop 32-bit support. it is actively being deliberated in two different TSC work items.

@ariadne yeah, the benefits of a 64-bit address space are pretty overwhelming basically everywhere but the smallest embedded systems now

kind of how we don't really use 8-bit MCUs any more (in new designs)

@whitequark @ariadne you'll have to rip xmegas from my dead cold paws :<

@littlefox @ariadne and i ship a new product (but not a new design) with a 8051, but that doesn't change that it's morally and technically beyond obsolete

@whitequark @ariadne I'm old enough that I don't like change I guess xD

Also I'm not designing products; just stuff for myself, so it's fine

@littlefox @ariadne you are literally younger than me, sister.

@ariadne is this for TCG or just KVM? Linux sadly already dropped KVM support for 32-bit hosts on ARM in 2020 (and there were some patches on LKML in 2024 removing 32-bit host support for other architectures but I don't think they ever got merged)

@whitequark @ariadne .... I don't know why, but somehow one estimated you younger than me 🙃

@ariadne What’s wild to me is that they already have abandoned emulation of early x86-64 chips. Bit me HARD when adding new machines to an old cloud platform.

@littlefox @whitequark @ariadne yeah, i'm still having fun with AVR MCUs (love how self-contained and terse the datasheets are), but indeed, 8-bit MCUs are fast obsolete :(

…and i'm younger than both of you :P

@confusomu @littlefox @ariadne I think AVRs have an excellent ethos and STM32s are a huge PITA for beginners! we have much to learn from the 8-bit devices still. but it's really hard to justify doing new projects on them, in no small part because the tiny address space means they run a weird and semi-incompatible language dialect (C, Rust, whatever)

also they're usually absurdly slow and power-hungry for the compute they're doing

@noisytoot @ariadne

> is this for TCG or just KVM?

Both, unfortunatly.
