POSIX leaves the signedness of time_t and clock_t unspecified, but
mainstream implementations (Linux glibc/musl, the BSDs, macOS, RTEMS,
Zephyr's POSIX layer, Windows _time64) expose time_t as signed 64-bit.
NuttX has historically used uint64_t only because it was tied to the
CONFIG_SYSTEM_TIME64 knob; with that gone, switch:
time_t : uint64_t -> int64_t
clock_t : uint64_t -> int64_t
CLOCK_MAX: UINT64_MAX -> INT64_MAX
This lets (time_t)-1 sentinels, negative tick deltas, and host-side
headers behave as on every other POSIX system without source churn.
Headers updated:
- include/sys/types.h, include/limits.h, include/nuttx/clock.h
- include/nuttx/fs/hostfs.h (nuttx_time_t alias)
- include/nuttx/{mqueue.h,wdog.h,wqueue.h,timers/clkcnt.h}
Because clock_t is now signed 64-bit, the NuttX-internal sclock_t
alias becomes redundant: every sclock_t/SCLOCK_MAX use is folded
back to clock_t/CLOCK_MAX (notably in sched/wdog, sched/mqueue,
sched/sched, sched/clock, sched/timer, libs/libc/time, fs/vfs and
the drivers/arch consumers below).
Tick/period constants (NSEC_PER_SEC, USEC_PER_SEC, MSEC_PER_SEC,
SEC_PER_MIN, ...) in include/nuttx/clock.h are retyped from "long"
literals to INT64_C(...) so that 64-bit arithmetic no longer
depends on the host's long width.
Strip now-redundant (time_t)/(clock_t)/(unsigned long) casts and
unsigned-only branches across the tree:
- arch RTC / oneshot / tickless lowerhalfs:
arm: cxd56xx, efm32, imxrt, lc823450, max326xx, sam34, sama5,
samd5e5, samv7, stm32, stm32f7, stm32h7, stm32l4, stm32wb,
xmc4
mips: pic32mz sparc: bm3803 x86_64: intel64
risc-v/xtensa: espressif (esp_i2c[_slave], esp_rtc,
esp32c3{_i2c,_rtc,_wifi_adapter}, esp32{,s2,s3}_*),
mpfs_perf
- drivers: audio/tone, input/aw86225, power/pm/{activity,
stability}_governor, rpmsg/rpmsg_ping,
timers/{ds3231,mcp794xx,pcf85263,rx8010},
wireless/ieee80211/bcm43xxx, wireless/spirit/spirit_spi
- core: fs/vfs/{fs_poll,fs_timerfd}, mm/iob/iob_alloc,
libs/libc/{netdb/lib_dnscache,time/{lib_calendar2utc,
lib_time}}, net/icmp/icmp_pmtu, net/icmpv6/icmpv6_pmtu,
net/ipfrag, net/tcp/{tcp.h,tcp_timer},
net/utils/net_snoop, net/mld/mld_query (drop the now-dead
mld_mrc2mrd helper since signed math handles it directly),
sched/clock/{clock,clock_initialize},
sched/sched/{sched_profil,sched_setparam,sched_setscheduler},
sched/pthread/pthread_create,
sched/wdog/{wd_gettime,wd_start,wdog.h},
sched/timer/timer_gettime, sched/mqueue/*
Flip the few in-tree printf format strings that assumed an
unsigned 64-bit tv_sec:
* drivers/rpmsg/rpmsg_ping.c PRIu64 -> PRId64
* arch/xtensa/src/esp32{,s2,s3}/esp32*_oneshot_lowerhalf.c
PRIu32 (already wrong) -> PRId64
