Robert HH 71df60cf42 esp8266/ets_alt_task.c: Prevent spurious large increment of ticks_ms()
This happened when the overflow counter for ticks_ms() was interrupted
by an external hard interrupt (issue #3076).

Damien George 34e0198436 esp8266: Extend system microsecond counter to 64-bits; use in ticks_ms.
So now ticks_ms can count up to the full 30 bits.  Fixes issue #2412.

Paul Sokolovsky 3fe047f08f esp8266/ets_alt_task: ets_post: Should return 0 on success, !0 - failure. 2016-09-18 23:01:58 +03:00
Damien George 927388e80e esp8266: Provide a dedicated variable to disable ets_loop_iter.
So ets_loop_iter is now only disabled when using machine.disable_irq.

Damien George 849eb835f0 esp8266/ets_alt_task: Don't run ets_loop_iter if irqs are disabled.
ets_loop_iter processes pending tasks, and tasks are considered lower
priority than interrupts, so tasks shouldn't be processed if interrupts
are disabled.

Damien George 556a1df6fd esp8266/ets_alt_task: Make FIRST_PRIO=0 to cover all task priorities.
FIRST_PRIO=2 works but using 0 is hopefully safer, and can anyway be
optimised in the future.

Paul Sokolovsky 54fc247f9b esp8266/ets_alt_task: Update for vendor SDK 1.5.0.
SDK 1.5.0 has a task with priority 3: ets_task(401001f4, 3, 3fff9808, 4).
Recognizing SDK version requires the latets esp-open-sdk build.

Paul Sokolovsky 97375f4576 esp8266/ets_alt_task: Be sure to "pop" event before calling its handler.
Otherwise, if handler calls recursive event loop, there's infinite
recursion (because the loop calls the same handler on same event again).

Paul Sokolovsky 97c2628900 esp8266: Add alternative event loop implementation.
This implementation provides the same interface and uses the same
datastructures as used by BootROM, i.e. is a drop-in replacement for it.
But it offers one advantage: it allows to run single iteration of
event-pumping loop.

Original BootROM function are renamed, prefixed with underscore. There's
a switch which allows to use forward calls to them, for compatibility
testing.

The implementation also includes workarounds for hardware timer handler,
and these workarounds may be SDK version specific.
