From d3c4e4a20a05085eae8d568c7efdbe09bada9cf5 Mon Sep 17 00:00:00 2001 From: Dario Nieuwenhuis Date: Mon, 3 Apr 2023 01:18:27 +0200 Subject: executor: add Pender, rework Cargo features. 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). --- embassy-executor/Cargo.toml | 25 ++++++++++++++++++++----- 1 file changed, 20 insertions(+), 5 deletions(-) (limited to 'embassy-executor/Cargo.toml') diff --git a/embassy-executor/Cargo.toml b/embassy-executor/Cargo.toml index 8ad3fd698..bb8a46c82 100644 --- a/embassy-executor/Cargo.toml +++ b/embassy-executor/Cargo.toml @@ -31,9 +31,22 @@ flavors = [ features = ["std", "nightly", "defmt"] [features] -default = [] -std = ["critical-section/std"] -wasm = ["dep:wasm-bindgen", "dep:js-sys"] + +# Architecture +_arch = [] # some arch was picked +arch-std = ["_arch", "critical-section/std"] +arch-cortex-m = ["_arch", "dep:cortex-m"] +arch-xtensa = ["_arch"] +arch-riscv32 = ["_arch"] +arch-wasm = ["_arch", "dep:wasm-bindgen", "dep:js-sys"] + +# Enable creating a `Pender` from an arbitrary function pointer callback. +pender-callback = [] + +# Enable the thread-mode executor (using WFE/SEV in Cortex-M, WFI in other embedded archs) +executor-thread = [] +# Enable the interrupt-mode executor (available in Cortex-M only) +executor-interrupt = [] # Enable nightly-only features nightly = [] @@ -55,9 +68,11 @@ embassy-macros = { version = "0.1.0", path = "../embassy-macros" } embassy-time = { version = "0.1.0", path = "../embassy-time", optional = true} atomic-polyfill = "1.0.1" critical-section = "1.1" -cfg-if = "1.0.0" static_cell = "1.0" -# WASM dependencies +# arch-cortex-m dependencies +cortex-m = { version = "0.7.6", optional = true } + +# arch-wasm dependencies wasm-bindgen = { version = "0.2.82", optional = true } js-sys = { version = "0.3", optional = true } -- cgit
