306: Retain cfg-attributes on resources r=korken89 a=AfoHT When rust 1.43 lands as stable this will resolve #301 and allow for the kind of conditional compilation exemplified in the issue. Tested on beta and nightly. Co-authored-by: Henrik Tjäder <henrik@tjaders.com>

307: Use build.rs for conditional compilation r=korken89 a=AfoHT Extend the current test suite to allow for running tests on newer rustc-versions than current MSRV. Required by #306 to add special tests for future MSRV. To exclude an example from the regular non-nightly testing: ``` #![no_main] #![no_std] #[cfg(rustc_is_nightly)] mod example { use panic_halt as _; #[rtfm::app(device = lm3s6965)] const APP: () = { <more code> } } ``` Co-authored-by: Henrik Tjäder <henrik@tjaders.com>

283: Include DWT enable in migration guide r=korken89 a=MabezDev Makes note of the fact the DWT has to be enabled manually in rtfm 0.5.0; an easy one to miss considering debuggers generally enable the DWT automatically. Co-authored-by: Scott Mabin <scott@mabez.dev>
2019-12-03Update migration guide to include the enabling of the the DWT peripheral. ↵Scott Mabin
Also makes note of enable trace with the DCB to allow the DWT to work without a debugger connected.

277: TimerQueue.dequeue: don't set SYST reload to 0 r=korken89 a=mpasternacki ARM Architecture Reference Manual says: "Setting SYST_RVR to zero has the effect of disabling the SysTick counter independently of the counter enable bit." If Monotonic's ratio is less than one, the timeout calculations can compute zero if next task is scheduled after current instant, but before next timer tick. This results in disabling SYST and freezing the timer queue. The division by ratio's denominator rounds downward and the dequeue condition is `if instant < now`. If ratio is small enough, this results in unnecessary interrupts: Let's say `instant - now` is 99 and ratio is 1/25. Then, `dur` will equal 3 and the next tick will happen at `now + 75`. In the next interrupt, `instant > now` and additional tick needs to be scheduled (which doesn't happen, because now `instant - now` is less than 25, so reload will be set to 0 and timer queue will stop). Adding one to computed duration will prevent both freezing and additional interrupts. When ratio is 1 or close, timer queue code overhead will prevent this from happening. I am working with a chip where CPU is clocked at 600MHz and SysTick is 100kHz and the freeze happens quite often. Co-authored-by: Maciej Pasternacki <maciej@3ofcoins.net>
