Split the merged #define macros on line 13 into separate lines to comply with coding standards and avoid potential preprocessor issues.

[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

[smart] Add vDSO support for RISC-V architecture and refactor related components

2025-05-19T10:29:26Z

- Implemented vDSO functionality for the RISC-V architecture, including the necessary source files and linker scripts. - Introduced a new `vdso_sys.c` file for RISC-V, containing functions to handle time retrieval using the vDSO mechanism. - Created architecture-specific linker scripts (`vdso.lds.S`) for both AArch64 and RISC-V. - Updated the build system to support vDSO compilation for RISC-V, including necessary adjustments in `SConstruct` files. - Refactored existing vDSO code to improve compatibility and maintainability across architectures. - Adjusted the maximum number of PTY devices in the terminal configuration from 64 to 32 for better resource management. - Fixed minor issues in existing code, including correcting the path for the vDSO shared library and ensuring proper function definitions.

kernel: cleanup debug APIs

2024-12-20T22:50:00Z

- `dbg_log` is a “NOT RECOMMENDED API”, convert the calling of this API to LOG_x and remove this API. - `dbg_here`/`dbg_enter`/`dbg_exit`: no one use these APIs, remove them directly. Signed-off-by: Chen Wang

feat: smart: user space context optimization

2024-09-20T03:02:39Z

This patch optimizes the user-space context handling in the ARM64 architecture, specifically improving how the context is saved and restored during system calls and interrupts. The changes make the code more efficient and easier to maintain, while ensuring proper preservation of user context during system transitions. Changes: - Introduced a parameter for context saving to improve flexibility. - Replaced hardcoded stack pointer operations with frame-relative references for better readability and code reuse. - Simplified context restoration, removing redundant operations like loading/storing floating-point registers.
