* kern: Add a mach host operation which returns elapsed time since bootupZhaoming Luo2024-12-291-0/+1
| | | | | | | | | | | | | | Add host_get_uptime64() mach interface operation. It can be used to get the time passed since the boot up. * doc/mach.texi: Add the documentation for the operation * include/mach/mach_host.defs: Add the interface * include/mach/time_value.h: Extend the mappable time variable * kern/mach_clock.c: Operation implementation * kern/mach_clock.h: Add a new variable for storing uptime Signed-off-by: Zhaoming Luo <zhmingluo@163.com> Message-ID: <20241224015751.1282-1-zhmingluo@163.com>

* Track task and thread time using time_value64_t.Flavio Cruz2023-03-131-1/+1
| | | | | | | | Changed kern/timer.c to use the higher precision time_value64_t. Of course, this won't suffer from the 2038 overflow but it does provide nanosecond precision (if gnumach ever uses a better timer) and moves us closer to only having time_value64_t.

* Add host_get_time64 RPC to return the time as time_value64_tFlavio Cruz2023-01-191-1/+1
| | | | | | Also updated the mapped time to support the new 64-bit time while keeping compatible with the user land programs currently using it so they can be migrated in parallel.
* Introduce time_value64_t to keep track of real time in the kernelFlavio Cruz2023-01-031-0/+1
| | | | | | | | | | | | time_value64_t uses int64_t to track seconds and nanoseconds and hence is Y2038 proof. It does not have nano second resolution but it could be provided in the future. Removed include/sys/time.h as it remaps time_value_t into timeval which can create confusion. The timestamp from keyboard and mouse events is no longer set and replaced with rpc_time_value for better compatibility.

* kern: add boot-time clock, use it for time stampsJustus Winter2015-07-251-1/+10
| | | | | | | | | | | | | | | | | | | | | | The kernel keeps track of task and thread creation times by saving a time stamp. Previously, the real-time clock was used for this. When the real-time clock is changed, however, the reference frame for the time stamps is lost. This surfaced in Hurd systems reporting spuriously long uptimes. Fix this by creating a boot-time clock and use it as reference frame for the time stamps. * kern/mach_clock.c (clock_boottime_offset): Create clock by keeping track of the offset from the real-time. (clock_boottime_update): New function. (record_time_stamp): Use the boot-time clock for time stamps. (read_time_stamp): New function to convert it back to real-time. (host_set_time): Call `clock_boottime_update'. * kern/mach_clock.h (record_time_stamp): Amend comment. (read_time_stamp): New declaration. * kern/task.c (task_info): Use `read_time_stamp'. * kern/thread.c (thread_info): Likewise.
