+* [#17244](https://github.com/apache/nuttx/pull/17244) [!] sched/event:
removed event_tickwait_wait() and added TSTATE_WAIT_EVENT
+ This PR contains breaking changes for event implementation to improve its
performance, safety and make its api cleaner and easier to use
+ Change summary:
+ Refactors the event module by removing its dependency on semaphores and
separate wait objects, and introduces a new task state
+ TSTATE_WAIT_EVENT to simplify scheduling and improve maintainability.
+ Details:
+ 1. Remove semaphore dependency
+ Reason:
+ - Semaphore objects consume more memory than necessary for event
synchronization.
+ - Semaphore interfaces are relatively complex, involving global locks and
logic that exceeds
+ the needs of the event mechanism.
+ Benefit:
+ - Simplifies the event module and reduces runtime and memory overhead.
+ 2. Remove wait object dependency
+ Reason:
+ - Wait objects introduce additional memory usage.
+ - The current design either uses a local wait object in the waiting task
(which is unsafe because the posting task also accesses it)
+ or requires users to define global wait objects and call
event_tickwait_wait(). This leads to complicated and error-prone usage.
+ - By removing wait objects, the event module can be implemented more
cleanly.
+ Benefit:
+ - Simplifies API usage.
+ - Improves safety and code maintainability.
+ 3. Introduce TSTATE_WAIT_EVENT and move the scheduling list to the event
object
+ Reason:
+ - Makes the event module implementation more concise.
+ - Allows the scheduler to handle tasks blocked on events more flexibly in
special cases (e.g., task deletion).
+ Benefit:
+ - Improves modularity and better integrates event handling with the
scheduler.
+ Impact
+
+ This change streamlines the event mechanism by eliminating unnecessary
abstractions, reducing memory footprint,
+ and improving the clarity of both the implementation and external API, no
impact to other nuttx functions
