perf_gettime() and perf_getfreq() are kernel functions, defined in sched/clock/clock_perf.c. Neither appears in syscall.csv, and libc supplies only perf_gettime(), under CONFIG_ARCH_HAVE_PERF_EVENTS_USER_ACCESS. So a protected or kernel build cannot resolve either of them from user space: ostest/perf_gettime.c:91: undefined reference to `perf_gettime' ostest/perf_gettime.c:184: undefined reference to `perf_getfreq' make[1]: *** [nuttx_user.elf] Error 1 The call in user_main() is guarded by CONFIG_ARCH_PERF_EVENTS && !CONFIG_ARCH_PERF_EVENTS_USER_ACCESS -- which is exactly the case where the symbols are kernel-only -- so every such configuration fails to link. mps3-an547:knsh is one: it sets CONFIG_SCHED_IRQMONITOR, which makes ARCH_PERF_EVENTS default y. mps2-an521:knsh escapes only because it sets neither monitor, leaving ARCH_PERF_EVENTS off, so the call compiles out and the archive member is never pulled in. Require CONFIG_BUILD_FLAT, where ostest links against the kernel's own copy. No configuration that runs the test today stops running it.
