if you enjoy looking at WIP things, I wrote a PoC async/await no_std impl for Cortex-M microcontrollers https://github.com/japaric/no-std-async-experiments-2/tree/do-not-delete-2019-12-03 … In addition to the code (runnable in QEMU) there's a write-up about the design / impl in the README I'll prob write a proper blog post at some point

It took me forever but I have finally released v0.1.0 (not a beta pre-release) of `ufmt`, a (6-40x) smaller and (2-9x) faster alternative to `core::fmt`. In this release the family of `uwrite!` macros works on stable thanks to `proc-macro-hack`! https://crates.io/crates/ufmt/0.1.0 …https://twitter.com/japaric_io/status/1126046642673717248 …

Real Time for the Masses goes multi-core
https://blog.japaric.io/multicore-rtfm/
The upcoming release of the concurrency framework ships with support for multi-core Cortex-M devices. Learn what parts of the single-core API can be used in multi-core context (spoilers: all of it)Thanks. Twitter will use this to make your timeline better. UndoUndo -
... we need to decide on several small breaking changes that will affect single-core applications. If you are a current or future RTFM user we would appreciate your input on these RFCs: https://github.com/japaric/cortex-m-rtfm/milestone/4 … (2/2)

P.S. I think this is the most systems program-y stuff I have done while using an OS (raw system calls) It's also the most segfaults I have gotten from unsafe Rust code, ever ABI contracts, assembly and non-standard calling conventions are all very easy to get wrong

Implementing the timer queue feature and even multi-core support doesn't seem like it would be too hard but IDK what would be the best way to do IO RTFM wants *signals* on IO events but I don't think any of the Linux IO API uses signals? (haven't read epoll et al man pages yet)

Real Time for The Masses (RTFM) running on ... (x86_64) Linux (?!) https://github.com/japaric/linux-rtfm … Deadlock-free memory sharing and message passing both work and apps run on a single CPU I have no idea what you would use this for, though. Maybe some soft real time embedded Linux app?pic.twitter.com/kWNWdGcuQz

Been doing Embedded Linux in
