The InterruptSource bindings let us call qemu_set_irq() and sysbus_init_irq() as safe code. Interrupt sources, qemu_irq in C code, are pointers to IRQState objects. They are QOM link properties and can be written to outside the control of the device (i.e. from a shared reference); therefore they must be interior-mutable in Rust. Since thread-safety is provided by the BQL, what we want here is the newly-introduced BqlCell. A pointer to the contents of the BqlCell (an IRQState**, or equivalently qemu_irq*) is then passed to the C sysbus_init_irq function. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
QEMU bindings and API wrappers
This library exports helper Rust types, Rust macros and C FFI bindings for internal QEMU APIs.
The C bindings can be generated with bindgen, using this build target:
$ make bindings.inc.rs
Generate Rust documentation
Common Cargo tasks can be performed from the QEMU build directory
$ make clippy
$ make rustfmt
$ make rustdoc
