Paolo Bonzini	1d03e9771e	rust: add --check-cfg test to rustc arguments rustc will check that every reachable #[cfg] matches a list of the expected config names and values. Recent versions of rustc are also complaining about #[cfg(test)], even if it is basically a standard part of the language. So, always allow it.

Paolo Bonzini	de98c17593	rust: build: move strict lints handling to rustc_args.py Make Cargo use unknown_lints = "allow" as well. This is more future proof as we might add new lints to rust/Cargo.toml that are not supported by older versions of rustc or clippy. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	1 year ago
Paolo Bonzini	90868c3dce	rust: cargo: store desired warning levels in workspace Cargo.toml An extra benefit of workspaces is that they allow to place lint level settings in a single Cargo.toml; the settings are then inherited by packages in the workspace. Correspondingly, teach rustc_args.py to get the unexpected_cfgs configuration from the workspace Cargo.toml. Note that it is still possible to allow or deny warnings per crate or module, via the #![] attribute syntax. The rust/qemu-api/src/bindings.rs file is an example.

Paolo Bonzini	97ed1e9c8e	rust: build: generate lint flags from Cargo.toml Cargo.toml makes it possible to describe the desired lint level settings in a nice format. We can extend this to Meson-built crates, by teaching rustc_args.py to fetch lint and --check-cfg arguments from Cargo.toml. --check-cfg arguments come from the unexpected_cfgs lint as well as crate features Start with qemu-api, since it already has a [lints.rust] table and an invocation of rustc_args.py.

Paolo Bonzini	1de82059aa	rust: build: restrict --cfg generation to only required symbols Parse the Cargo.toml file, looking for the unexpected_cfgs configuration. When generating --cfg options from the config-host.h file, only use those that are included in the configuration. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	1 year ago
Manos Pitsidianakis	37fdb2f56a	rust: add PL011 device model This commit adds a re-implementation of hw/char/pl011.c in Rust. How to build: 1. Configure a QEMU build with: --enable-system --target-list=aarch64-softmmu --enable-rust 2. Launching a VM with qemu-system-aarch64 should use the Rust version of the pl011 device Co-authored-by: Junjie Mao <junjie.mao@intel.com> Co-authored-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Junjie Mao <junjie.mao@intel.com> Signed-off-by: Manos Pitsidianakis <manos.pitsidianakis@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Link: https://lore.kernel.org/r/20241024-rust-round-2-v1-2-051e7a25b978@linaro.org	1 year ago
Manos Pitsidianakis	ca5aa28e24	Revert "rust: add PL011 device model" Patch was applied with invalid authorship by accident, which confuses git tooling that look at git blame for contributors etc. Patch will be re-applied with correct authorship right after this commit. This reverts commit `d0f0cd5b1f`.

Manos Pitsidianakis	6fdc5bc173	rust: add bindgen step as a meson dependency Add bindings_rs target for generating rust bindings to target-independent qemu C APIs. The bindings need be created before any rust crate that uses them is compiled. The bindings.rs file will end up in BUILDDIR/bindings.rs and have the same name as a target: ninja bindings.rs Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Manos Pitsidianakis <manos.pitsidianakis@linaro.org> Link: https://lore.kernel.org/r/1be89a27719049b7203eaf2eca8bbb75b33f18d4.1727961605.git.manos.pitsidianakis@linaro.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	2 years ago
