* sysdeps/unix/sysv/linux/kernel-posix-cpu-timers.h: New file. * sysdeps/unix/sysv/linux/clock_getcpuclockid.c: New file. * sysdeps/unix/sysv/linux/ia64/clock_getcpuclockid.c (HAS_CPUCLOCK): New macro. (clock_getcpuclockid): Function removed. #include the new linux file to define it instead. * sysdeps/unix/clock_gettime.c [HP_TIMING_AVAIL] (hp_timing_gettime): New function, broken out of ... (clock_gettime) [HP_TIMING_AVAIL]: ... here. Call it. (realtime_gettime): New function, broken out of ... (clock_gettime) [! HANDLED_REALTIME]: ... here. Call it. (clock_gettime) [SYSDEP_GETTIME_CPU]: Use new macro in default case. * sysdeps/unix/sysv/linux/clock_gettime.c (SYSCALL_GETTIME): New macro. (SYSDEP_GETTIME_CPUTIME): New macro. (SYSDEP_GETTIME): Use both. [! __ASSUME_POSIX_TIMERS] (maybe_syscall_gettime): New function, broken out of ... (SYSDEP_GETTIME): ... here. Use it. [__NR_clock_gettime] (HANDLED_CPUTIME): Define it. (SYSDEP_GETTIME_CPUTIME): New macro. Handle CPU timers by trying kernel support and falling back to hp-timing code. * sysdeps/posix/clock_getres.c [HP_TIMING_AVAIL] (hp_timing_getres): New function, broken out of ... (clock_getres) [HP_TIMING_AVAIL]: ... here. Call it. (realtime_getres): New function, broken out of ... (clock_getres) [! HANDLED_REALTIME]: ... here. Call it. (clock_getres) [SYSDEP_GETRES_CPU]: Use new macro in default case. * sysdeps/unix/sysv/linux/clock_getres.c (SYSCALL_GETRES): New macro. (SYSDEP_GETRES_CPUTIME): New macro. (SYSDEP_GETRES): Use both. [! __ASSUME_POSIX_TIMERS] (maybe_syscall_getres): New function, broken out of ... (SYSDEP_GETRES): ... here. Use it. [__NR_clock_getres] (HANDLED_CPUTIME): Define it. (SYSDEP_GETRES_CPUTIME): New macro. Handle CPU timers by trying kernel support and falling back to hp-timing code. * sysdeps/unix/sysv/linux/clock_nanosleep.c: Handle CLOCK_PROCESS_CPUTIME_ID and CLOCK_PROCESS_THREAD_ID specially, translating to the kernel clockid_t for our own process/thread clock.
