terry0012 opened a new pull request, #4035:
URL: https://github.com/apache/nuttx-apps/pull/4035
## Summary
- Add long-press exit monitoring to monkey through the `-e` option
(default: `/dev/input0`, threshold: 2500ms).
- Use a poll loop with signalfd and timerfd for signal handling and
event scheduling.
- Make monkey/input-tool dependencies explicit, expose the input
generator configuration, and retain automatic selection of
LIBC_PRINT_EXTENSION for monkey logging.
## Impact
The exit-monitor device is grabbed exclusively until monkey exits.
SIGTERM exits through normal cleanup; SIGTSTP/SIGCONT pause and resume
input generation.
Board configurations must explicitly enable the required dependencies.
A corresponding NuttX qemu-armv7a:full defconfig update is needed to
keep the input tool enabled.
## Testing
- Native simulator build and 28 runtime checks passed for the unchanged
monkey C implementation, covering signals, multiple instances,
pause/resume, short/long presses, grab release and restart.
- Validated the final Kconfig dependencies and the updated QEMU defconfig.
- Source formatting, commit-message and whitespace checks passed.
- No QEMU ARM cross-build or hardware testing performed. Simultaneous
signal/timer readiness remains unverified.
