## Summary This PR adds sched_note_syscall_enter/leave hooks for the system call instrumentation. In FLAT build, syscall wrapper library is created. In PROTECTED/KERNEL build, insert the hooks in system call proxy library. ## Impact It should be no impact by default configuration. To use the feature, CONFIG_SCHED_INSTRUMENTATION_SYSCALL must be enabled. At this moment, only Arm and RISC-V can enable it. ## Testing Tested by spresense:nsh and maix-bit:nsh by changing the following configurations. CONFIG_DRIVER_NOTE=y CONFIG_SCHED_INSTRUMENTATION=y CONFIG_SCHED_INSTRUMENTATION_BUFFER=y CONFIG_SCHED_INSTRUMENTATION_SYSCALL=y CONFIG_SCHED_NOTE_GET=y CONFIG_SYSTEM_NOTE=y "note" command displays the system call information. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
