* [embassy-executor] improved documentationBarnaby Walters2023-12-221-0/+3
| | | | | | | | | | | | * Feature auto-documentation * Task arena sizes in a <details> list * Non-documented comment explaining turbowakers with see-also link Further improvements: * Are the task-arena-size-* numbers sizes in bytes? or something else? * Task arena section could benefit from advice about how to choose a suitable size
* executor: rename macro crate to embassy-executor-macros, bump it.Dario Nieuwenhuis2023-12-077-9/+9

* executor: remove arch-xtensa.Dario Nieuwenhuis2023-12-032-92/+1
| | | | | | | | It's been broken for months and nobody has noticed. The `esp*-hal` crates have much better support. Fixes #2234 Closes #1912

* executor: add Pender, rework Cargo features.Dario Nieuwenhuis2023-04-037-356/+602
| | | | | | | | | 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 Nieuwenhuis2023-03-302-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | 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.
