If you do so you have to add -fno-builtins (or just -fno-builtin-memcpy).

You have to release the whole system under the SSPL . So there could be a reading where you can't use Linux, you can't use systemd, you can't use glibc, etc.

``` is markdown for pre formatted text. It puts the LLM in the mood of generating machine readable data instead of prose.

Smart pointers are not really about managing memory, they're about managing lifetimes. Even things like the Rust RefCell are smart pointers.

Because it's not about devs, it's about distro packagers. They are an extremely important audience for QEMU. As pm215 said above, we don't want to make their lives unnecessarily harder. For example Debian has the backports re

Well, smart pointers and (sort of) templates and lambdas are in Rust. I definitely want smart pointers.

We already make an exception in that we don't support Debian bullseye (which is supported by the rest of QEMU until the April 2025 release), but not supporting Debian stable at all seemed too much. That said we will probably switch t

In Rust's case it is that when you say "you have IsA<Device> for all types that implement IsA<PCIDevice>" you are actually saying "you have IsA<Device> for all types, but only if they implement IsA<P

And really it's not so much fighting the compiler as it's understanding your code better—in ways that help you even when writing C. The times that you do fight the compiler it will suggest the right thing (add clone, add &, ad

The object model in QEMU is from 2007-2011. Internally there isn't a lot of inheritance (it's pretty shallow), but yeah I guess "is-a" is what was in vogue at the time. However there is a reason to have the object model,

The legacy reset way is fine, and yeah this is where being more strict and doing more stuff within the language should help.

Right now the only language-level thing I would like is const operator overloading. Even supporting MSRV as old as 1.63 was not a big deal, the worst thing was dependencies using let...else which we will vendor and patch. Pin is what it is,

QEMU has several tracepoint providers, the main ones are (a slightly fancy version of) printf and USDT. There is a Python program that generates the C code for the chosen backend(s), so the thing to do would be to adjust the script to produ

Thanks for posting this to HN! Author here, happy to answer any questions. (By the way, I did not originally start the project, though I've worked quite a bit on the safe abstractions that are mentioned in the roadmap).

Just one nit: contrary to what the article suggests, as far as I remember the compact model was not so common because using far pointers for all data is slow and wastes memory. Also, the globals and the stack had to fit in 64k anyway so com

Regressions in upstream kernel exist; they may be security issues, assertion failures, performance regressions, and so on. It's just too much work to validate a whole new kernel every six months, and also much harder to pinpoint a reg
