[components][clock_time] Refactor time subsystem around clock_time (#11111)

2026-01-31T09:44:27Z

* [components][clock_time] Refactor time subsystem around clock_time Introduce the clock_time core with clock source/event separation, high-resolution scheduling, and boot-time helpers, plus clock_timer adapters for timer peripherals. Remove legacy ktime/cputime/hwtimer implementations and migrate arch and BSP time paths to the new subsystem while keeping POSIX time integration functional. Update drivers, Kconfig/SConscript wiring, documentation, and tests; add clock_time overview docs and align naming to clock_boottime/clock_hrtimer/clock_timer. * [components][clock_time] Use BSP-provided clock timer frequency on riscv64 * [risc-v] Use runtime clock timer frequency for tick and delays * [bsp] Add clock timer frequency hooks for riscv64 boards * [bsp] Update Renesas RA driver doc clock_timer link * [bsp] Sync zynqmp-r5-axu4ev rtconfig after config refresh * [bsp][rk3500] Update rk3500 clock configuration * [bsp][hpmicro] Add rt_hw_us_delay hook and update board delays * [bsp][stm32l496-st-nucleo] enable clock_time for hwtimer sample in ci * [bsp][hpmicro] Fix rtconfig include scope for hpm6750evk Move rtconfig.h include outside the ENET_MULTIPLE_PORT guard for hpm6750evk and hpm6750evk2 so configuration macros are available regardless of ENET settings. * [bsp][raspi3] select clock time for systimer * [bsp][hpm5300evk] Trim trailing blank line * [bsp][hpm5301evklite] Trim trailing blank line * [bsp][hpm5e00evk] Trim trailing blank line * [bsp][hpm6200evk] Trim trailing blank line * [bsp][hpm6300evk] Trim trailing blank line * [bsp][hpm6750evk] Trim trailing blank line * [bsp][hpm6750evk2] Trim trailing blank line * [bsp][hpm6750evkmini] Trim trailing blank line * [bsp][hpm6800evk] Trim trailing blank line * [bsp][hpm6e00evk] Trim trailing blank line * [bsp][nxp] switch lpc178x to gcc and remove mcx timer source * [bsp][stm32] fix the CONFIG_RT_USING_CLOCK_TIME issue. * [docs][clock_time] add clock time documentation * [docs][clock_time] Update clock time subsystem documentation - Update device driver index to use correct page reference - Clarify upper layer responsibilities in architecture overview - Update README to describe POSIX/libc, Soft RTC, and device driver usage - Refine architecture diagram with improved layout and color scheme - Remove obsolete clock_timer.md file * [kernel][utest] Trim trailing space * [clock_time] Fix hrtimer wrap handling * [clock_time] fix the static rt_inline issue * [clock_time] fix the rt_clock_hrtimer_control result issue

:truck: renaming: move `smp` to `smp_call`

feat: smp_call: added signaling call_req

2024-11-03T02:08:45Z

This patch introduces `rt_smp_call_request` API to handle queued requests across cores with user provided data buffer, which provides a way to request IPI through a non-blocking pattern. It also resolved several issues in the old implementation: - Multiple requests from different cores can not be queued in the work object of the target core. - Data racing on `rt_smp_work` of same core. If multiple requests came in turns, or if the call is used by the target cpu, while a new request is coming, the value will be overwrite. - Memory vulnerability. The rt_smp_event is allocated on stack, though the caller may not wait until the call is done. - API naming problem. Actually we don't provide a way to issue an IPI to ANY core in mask. What the API do is aligned to MANY pattern. - FUNC_IPI registering to PIC. Changes: - Declared and configured the new `RT_SMP_CALL_IPI` to support functional IPIs for task requests across cores. - Replaced the single `rt_smp_work` array with `call_req_cores` to manage per-core call requests safely. - Added `_call_req_take` and `_call_req_release` functions for atomic handling of request lifetimes, preventing data race conditions. - Replaced single event handling with a queue-based approach (`call_queue`) for efficient multi-request processing per core. - Introduced `rt_smp_call_ipi_handler` to process queued requests, reducing IPI contention by only sending new requests when needed. - Implemented `_smp_call_remote_request` to handle remote requests with specific flags, enabling more flexible core-to-core task signaling. - Refined `rt_smp_call_req_init` to initialize and track requests with atomic usage flags, mitigating potential memory vulnerabilities.

[libcpu] quality: call PV_OFFSET on entry for once

2024-07-17T05:23:52Z

This patch improves the efficiency and readability of the AArch64 common setup code by calculating the `PV_OFFSET` once at the start and reusing the value. This change reduces redundant calculations. Signed-off-by: Shell
