Do not going harassing developers because you think they are doing it wrong. If you can do better and don't want to actually contribute to the upstream you are always free to fork it.

In my first proper job as a software engineer I wrote a bunch of Forth for "fruit machines". I don't know what the US equivalent would be but they are low stakes gambling machines which are quite common in UK pubs. The core p

The talks have also now gone up on the YouTube channel: https://www.youtube.com/@kvmforum6546/videos including my keynote based on top QEMU stories in Hacker News for the year ;-)

Isn't this basically the background to HZD: Frozen Wastes? A failing geoengineering project to keep Yellowstone stable.

I think they mean the assumed parameter size of GPT-4 is so large you couldn't run it on commodity hardware even if you could get hold of the model.

The plugins have access to the instruction stream to make architecture specific decisions. What I meant by architecture independent is that it doesn't involve per-guest annotations in the frontends to handle - any guest using the commo

The upstream now has TCG plugins ( https://qemu.readthedocs.io/en/latest/devel/tcg-plugins.html ) which allow for a degree of instrumentation. The implementation is architecture agnostic and also tested within

The 64bit Aarch64 ISA has very little in common with the original ISA from '85.

AIUI that is mainly achieved by running the native library functions.Given how much time you spend in library functions I'm not surprised it has an edge over the full translation of the application.

Since v4.0.0 (see https://git.qemu.org/?p=qemu.git;a=commitdiff;h=a94b783952cc... ). We are always up for improving the code generation quality but of course there is a trade off with JITs given we are not compilers. I suspe

We do use the host FPU for a subset of floating point operations now. However it only really works for clean 32/64 IEEE FP so anything that goes through the x87 still needs software emulation.

I should point out that the awesome part of this work is unlike a lot of academic exercises this was done in collaboration with the community. As a result much of the work is merged upstream and QEMU gets to benefit.
