Fix-Point opened a new pull request, #21342: URL: https://github.com/apache/nuttx/pull/21342
*Note: Please adhere to [Contributing Guidelines](https://github.com/apache/nuttx/blob/master/CONTRIBUTING.md).* ## Summary This PR improves spinlock/rspinlock performance and adds inline control: 1. `ticked_spinlock: Improve the performance of ticket spinlock` — optimize ticket spinlock performance. 2. `spinlock: Improve the performance of rspinlock` — restructure rspinlock with `val`/`local_val` fields and `RSPINLOCK_*` macros. 3. `spinlock: Add compiler_assume for rspinlock` — add compiler hint optimization. 4. `spinlock: Fix Coverity CONSTANT_EXPRESSION_RESULT in rspin_lock` — Coverity fix. 5. `spinlock: add CONFIG_SPINLOCK_INLINE to control inlining` — add `CONFIG_SPINLOCK_INLINE` option to control inline vs non-inline helpers. 6. `spinlock: fix uninitialized ret in rspin_trylock` — fix uninitialized return value. 7. `spinlock: Add WFE/SEV optimization to prevent livelock` — add `UP_WFE()`/`UP_SEV()` optimization to prevent livelock. 8. `spinlock: remove UP_DSB() in WFE/SEV (release has barrier semantics)` — remove redundant `UP_DSB()` calls (release operations already have barrier semantics). 9. `irq: add irq_save/irq_restore wrapper and replace up_irq_save calls` — add `irq_save()`/`irq_restore()` wrapper and replace `up_irq_save()`/`up_irq_restore()` calls. ## Impact - **Build process**: adds `CONFIG_SPINLOCK_INLINE` Kconfig option (default `!DEFAULT_SMALL`). - **Hardware**: uses `UP_WFE()`/`UP_SEV()` (ARM/RISC-V low-power wait/event instructions) to prevent livelock; removes redundant `UP_DSB()` calls. - **Performance**: rspinlock uses `local_val` (local copy) to avoid atomic read/write; ticket spinlock optimized. - **Compatibility**: `irq_save()`/`irq_restore()` wrapper replaces `up_irq_save()`/`up_irq_restore()` calls (behavior unchanged). - **Security**: no impact. ## Testing - **Host machine**: Linux x86_64 - **Board**: rv-virt (QEMU RISC-V 32-bit) - **Config**: `rv-virt:smp` - **Toolchain**: riscv64-unknown-elf-gcc (rv32 multilib) - **Test**: compile (`make`) + QEMU ostest passed ``` ➜ qemu-system-riscv32 -semihosting -M virt,aclint=on -cpu rv32 -smp 8 -bios none -nographic -kernel nuttx -s nsh> ostest stdio_test: write fd=1
