This concludes the part of the qdev bindings that is needed to convert pl011 to safe Rust, with the exception of chardev bindings and switching to the pinned_init crate.
It includes reference counting, object creation, clocks, Resettable and MemoryRegionOps. Documentation is at least decent. The code is getting closer to the synopsis at https://lists.nongnu.org/archive/html/qemu-rust/2024-12/msg00006.html, except that it works (at least as far as CI is concerned) instead of just compiling. :) And since I'm citing it, a reminder that it may still be worth asking your Rust questions as replies to that message. You can find the code in the rust-next branch of https://gitlab.com/bonzini/qemu/. Paolo RFC->v1: - improvements and fixes for docs and comments - fixed Sync/Send declarations for Owned - prefer NonNull::cast (could use NonNull<> arguments too in the future) - add Send markers too, not just Sync - use impl_zeroable! macro - add qdev_init_clock_out() too - add comments about when to use Owned<> - add Owned::clone - add conversion of pl011_create to safe Rust for more uses of Owned<> Paolo Bonzini (12): rust: qom: add reference counting functionality rust: qom: add object creation functionality rust: callbacks: allow passing optional callbacks as () rust: qdev: add clock creation rust: qom: allow initializing interface vtables rust: qdev: make ObjectImpl a supertrait of DeviceImpl rust: qdev: switch from legacy reset to Resettable rust: bindings: add Send and Sync markers for types that have bindings rust: bindings for MemoryRegionOps rust: irq: define ObjectType for IRQState rust: chardev, qdev: add bindings to qdev_prop_set_chr rust: pl011: convert pl011_create to safe Rust meson.build | 1 + rust/hw/char/pl011/src/device.rs | 121 +++++++------- rust/hw/char/pl011/src/lib.rs | 1 - rust/hw/char/pl011/src/memory_ops.rs | 34 ---- rust/qemu-api/meson.build | 2 + rust/qemu-api/src/bindings.rs | 46 ++++++ rust/qemu-api/src/callbacks.rs | 97 ++++++++++++ rust/qemu-api/src/chardev.rs | 19 +++ rust/qemu-api/src/irq.rs | 18 ++- rust/qemu-api/src/lib.rs | 2 + rust/qemu-api/src/memory.rs | 191 ++++++++++++++++++++++ rust/qemu-api/src/prelude.rs | 4 + rust/qemu-api/src/qdev.rs | 227 ++++++++++++++++++++++++--- rust/qemu-api/src/qom.rs | 218 ++++++++++++++++++++++++- rust/qemu-api/src/sysbus.rs | 39 ++++- rust/qemu-api/src/vmstate.rs | 10 +- rust/qemu-api/src/zeroable.rs | 1 + rust/qemu-api/tests/tests.rs | 45 +++--- 18 files changed, 924 insertions(+), 152 deletions(-) delete mode 100644 rust/hw/char/pl011/src/memory_ops.rs create mode 100644 rust/qemu-api/src/chardev.rs create mode 100644 rust/qemu-api/src/memory.rs -- 2.48.1
