xiaoliud opened a new pull request, #4036:
URL: https://github.com/apache/nuttx-apps/pull/4036
## Summary
Raise the default GRAPHICS_INPUT_TOOL_STACKSIZE from
DEFAULT_TASK_STACKSIZE to 4096; DEFAULT_TASK_STACKSIZE was 2048 in the
affected configuration. On an ARMv8-M target with
CONFIG_SCHED_DUMP_ON_EXIT, the exit path of a signal-killed input task
overflowed the stack (PSPLIM, UsageFault STKOF). Coredump analysis
measured 1756 of 1880 usable bytes; the breakdown is in the commit
message.
## Impact
- Only the Kconfig default changes.
- Configurations that inherited a 2048-byte DEFAULT_TASK_STACKSIZE use
2048 more bytes while the input task runs; configurations that set the
stack size explicitly are unaffected.
- No API or documentation changes.
## Testing
- Host: Ubuntu 22.04 x86_64, gcc 13.1.0; sim:nsh with
CONFIG_GRAPHICS_INPUT_TOOL=y.
- Testing on sim covered compilation and basic input commands
(`input tap`, `input swipe`) only. The stack usage figures are
from the original coredump analysis described in the commit message.
- checkpatch.sh -c -u -m -g: pass.
- No hardware testing was performed on this branch.
