The cleanup involved three parts:
- Merging the standalone "/**@{*/" into
"@addtogroup group_thread_management"
- Changing "/**@}*/" to "/** @} group_thread_management */",
adding the group name makes it easier to find the matching "@{" part.
- Deleting the "@addtogroup" directive in "include/rtthread.h"
because this header file doesn't have doxygen comments.
All doxygen comments for function bodies are defined in other .c files.
Note, we remian two doxygen comments for rt_thread_inited_hookproto_t
and rt_thread_idle_sethook in the "include/rtthread.h".
rt_thread_inited_hookproto_t is really defined here.
For rt_thread_idle_sethook, please see FIXME comment for reason.

- Merging the standalone "/**@{*/" into
"@addtogroup group_object_management"

- Deleting the "@addtogroup" directive in "include/rtthread.h"
because this header file doesn't have doxygen comments.
All doxygen comments for function bodies are defined in "src/object.c".
Plus minor cleanup for group_hook in src/object.c.

Update RT_VERSION to 5.2.2.
|
|
|
|
For "RT-Thread User Guide":
Take the "RT-Thread Kernel Object Model" sub-section out of
the "Kernel Basics" section and rename it to "Object Management".
Correspondingly, rename the "Kernel Object Management" section
in the "RT-Thread API Guide" to "Object Management".

The originally defined "group_Device" should actually
be part of the device-driver component, so create
a new "group_device_driver" and then rename
"group_Device" to "group_device_driver".

(#10201)
include ：rtdef.h : [ Refine the annotation of RT_ALIGN and RT_ALIGN_DOWN ]
This macro is vulnerable to non-2-byte alignments,
but I assume that the macro definition was designed with an explicit use case of 2-byte alignments in mind.
Therefore, I only modify the comment to remind the user.
Solution:
RT_ALIGN(size, align) ((size) + (align) - 1) / (align) * (align)
RT_ALIGN_DOWN(size, align) (size) / (align) * (align)
Here's what deepseek recommends more.

* doxygen: add prefix for groups
Add "group_" prefix to doxygen group names. This makes
it easier to grep with group name later.
This patch only modifies the groups defined in the pathes
of INPUT of documentation/Doxyfile:
INPUT = . \
../src \
../include \
../components/finsh \
../components/drivers/include/drivers \
../components/drivers/clk \
../components/dfs/dfs_v2/src \
../components/dfs/dfs_v2/include

- `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.

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.

These changes introduce the rt_interrupt_context family, providing a
mechanism for managing nested interrupts. The context management
ensures proper storage and retrieval of interrupt states, improving
reliability in nested interrupt scenarios by enabling context tracking
across different interrupt levels. This enhancement is essential for
platforms where nested interrupt handling is crucial, such as in real-
time or multi-threaded applications.
Changes:
- Defined rt_interrupt_context structure with context and node fields
in `rtdef.h` to support nested interrupts.
- Added rt_slist_pop function in `rtservice.h` for simplified node
removal in singly linked lists.
- Declared rt_interrupt_context_push, rt_interrupt_context_pop, and
rt_interrupt_context_get functions in `rtthread.h` to manage the
interrupt/exception stack.
- Modified AArch64 CPU support in `cpuport.h` to include
rt_hw_show_register for debugging registers.
- Refactored `_rt_hw_trap_irq` in `trap.c` for context-aware IRQ
handling, with stack push/pop logic to handle nested contexts.
- Implemented interrupt context push, pop, and retrieval logic in
`irq.c` to manage context at the CPU level.

When RT_USING_DEBUG is disabled, variables used only in RT_ASSERT
statements become unused, triggering -Wunused-but-set-variable compiler
warnings. These variables are essential for runtime assertions in debug
builds but appear unused in release builds.
Example:
- Variables used in RT_ASSERT(var != RT_NULL) checks
- Affects multiple drivers and components using RT_ASSERT
This is a general cleanup to improve code compilation without affecting
functionality.
