* executor: add Pender, rework Cargo features.Dario Nieuwenhuis2023-04-038-361/+622
| | | | | | | | | This introduces a `Pender` struct with enum cases for thread-mode, interrupt-mode and custom callback executors. This avoids calls through function pointers when using only the thread or interrupt executors. Faster, and friendlier to `cargo-call-stack`. `embassy-executor` now has `arch-xxx` Cargo features to select the arch and to enable the builtin executors (thread and interrupt).
* executor: unify export mod.Dario Nieuwenhuis2023-04-031-8/+4
|
* executor,sync: add support for turbo-wakers.Dario Nieuwenhuis2023-03-303-0/+37
| | | | | | | | | | | | | | | | | | | | | | | | This is a `core` patch to make wakers 1 word (the task pointer) instead of 2 (task pointer + vtable). It allows having the "waker optimization" we had a while back on `WakerRegistration/AtomicWaker`, but EVERYWHERE, without patching all crates. Advantages: - Less memory usage. - Faster. - `AtomicWaker` can actually use atomics to load/store the waker, No critical section needed. - No `dyn` call, which means `cargo-call-stack` can now see through wakes. Disadvantages: - You have to patch `core`... - Breaks all executors and other things that create wakers, unless they opt in to using the new `from_ptr` API. How to use: - Run this shell script to patch `core`. https://gist.github.com/Dirbaio/c67da7cf318515181539122c9d32b395 - Enable `build-std` - Enable `build-std-features = core/turbowakers` - Enable feature `turbowakers` in `embassy-executor`, `embassy-sync`. - Make sure you have no other crate creating wakers other than `embassy-executor`. These will panic at runtime. Note that the patched `core` is equivalent to the unpached one when the `turbowakers` feature is not enabled, so it should be fine to leave it there.

| | | | | | | | | | Export all main macro per target architecture from embassy-macros, and select the appropriate macro in embassy-executor.

|\ | | | | | | | | | | | | | | | | | | 1054: riscv fixes r=lulf a=swolix With these changes I can run embassy on our RISC-V processor, please consider merging this, feedback is very welcome. I don't fully understand the code in the executor, but I have implemented a critical section by globally disabling interrupts, which means the wfi inside the critical section will hang the whole thing.

* Add critical-section/std to std featureDaniel Bevenius2022-09-081-1/+1
| | | | | This commit suggests adding critical-section/std to the std feature as without this a link time error is generated.
* Ensure interrupt::take works without embassy-executorUlf Lilleengen2022-08-251-2/+2
| | | | | | Add "rtos-trace-interrupt" feature flag on embassy-macros and enable it for embassy-executor, to ensure that the interrupt::take! macro can be used without depending on embassy-executor.
* Enable 'std' feature on critical-section for WASMUlf Lilleengen2022-08-231-2/+2
| | | | | | This fixes the WASM support which was failing due to missing critical-section implementation. This also upgrades the bindgen dependency and ensures that tooling works.
