[ KeyLen | Key | Value ] + * 起始地址即为 flag 之后,数据紧凑排列,无需额外 malloc。 + * + * 2. ptr 模式 (大数据) + * - 当数据长度 > 阈值时,结构体存储一个指针,指向独立的堆区。 + * - 存储布局: + * [ KeyLen | *ptr ] -> (ptr指向) [ Key | Value ] + * - KeyLen 的大小由 flag 中的长度字段决定 (最多 4 字节)。 + * - 这样保证大数据不会撑爆结构体,同时保持 API 一致性。 + + * 其他类型的存储: + * - null / bool : 由 flag 位直接表示,无需额外空间。 + * - number : 根据 flag 扩展位决定存储 int(4字节) 或 double(8字节)。 + * - object : 动态分配空间存储子节点,采用链表结构。 + * + * 设计考量: + * - malloc 在嵌入式平台的开销: + * * RTT 最小内存管理算法中,malloc 头部约 12 字节(可以考虑tlsf算法头部空间仅4字节,内存碎片也控制的很好,适合物联网应用)。 + * * 一个 RyanJson 节点本身可能只有个位数字节,头部空间就让内存占用翻倍。 + * - 因此: + * * 小数据尽量 inline 存储,避免二次 malloc。 + * * 大数据 fallback 到 ptr 模式,保证灵活性。 + * - 修改场景: + * * 理想情况:节点结构体后面直接跟 key/strValue,修改时释放并重新申请节点。 + * * 但这样 changKey/changStrValue 接口改动太大,用户层需要修改指针,代价高。 + * * 实际策略:提供就地修改接口。 + * - 若新值长度 ≤ 原有 inline 缓冲区,直接覆盖。 + * - 若超过阈值,自动切换到 ptr 模式,用户层无需关心。 * - * - 因此采用指针方式,保证灵活性和低侵入性。 + * 链表结构示例: + * { + * "name": "RyanJson", + * next ( + * "version": "xxx", + * next ( + * "repository":

+ * - 这样保证大数据不会撑爆结构体,同时保持 API 一致性。 + + * 其他类型的存储: + * - null / bool : 由 flag 位直接表示,无需额外空间。 + * - number : 根据 flag 扩展位决定存储 int(4字节) 或 double(8字节)。 + * - object : 动态分配空间存储子节点,采用链表结构。 + * + * 设计考量: + * -

fallback 到 ptr 模式,保证灵活性。 + * - 修改场景: + * * 理想情况:节点结构体后面直接跟 key/strValue,修改时释放并重新申请节点。 + * * 但这样 changKey/changStrValue 接口改动太大,用户层需要修改指针,代价高。 + * * 实际策略:提供就地修改接口。 + * - 若新值长度 ≤ 原有 inline 缓冲区,直接覆盖。 + *

87
   * @brief 动态载荷存储区
88
     * 目的:
89
     * - 在保持 API 易用性和稳定性的同时,最大限度减少 malloc 调用次数。
90
     * - 尤其在嵌入式平台,malloc 代价高昂:不仅有堆头部空间浪费,还会产生内存碎片。
91
     * - 通过利用结构体内的对齐填充 (Padding) 和指针空间,形成一个灵活的缓冲区。
92
     *
93
     * 存储策略:
94
     * 利用结构体内存对齐产生的 Padding(如 Flag 后的空隙)以及原本用于存储指针的空间,形成一个缓冲区
95
     * 若节点包含 key / strValue,则可能有两种方案:
96
     * inline 模式 (小数据优化)
97
     *    - 当 (KeyLen + Key + Value) 的总长度 ≤ 阈值时,直接存储在结构体内部。
98
     *    - 阈值计算公式:
99
     *        阈值 = Padding + sizeof(void*) + (malloc头部空间的一半),再向上对齐到字节边界。
100
     *      举例:
101
     *        - 内存对齐:4字节
102
     *        - malloc头部空间:8字节
103
     *        - 可用空间 = 3 (flag后padding) + 4 (指针空间) + 4 (malloc头部一半)
104
     *        - 向上对齐后得到阈值12字节
105
     *    - 存储布局:
106
     *        [ KeyLen | Key | Value ]
107
     *      起始地址即为 flag 之后,数据紧凑排列,无需额外 malloc。
108
     *
109
     * ptr 模式 (大数据)
110
     *    - 当数据长度 > 阈值时,结构体存储一个指针,指向独立的堆区。
111
     *    - 存储布局:
112
     *        [ KeyLen | *ptr | Padding ] -> (ptr指向) [ Key | Value ]
113
     *    - KeyLen 的大小由 flag 中的长度字段决定 (最多 4 字节)。
114
     *    - 这样保证大数据不会撑爆结构体,同时保持 API 一致性。
115
116
     * 其他类型的存储:
117
   * - null / bool : 由 flag 位直接表示,无需额外空间。
118
   * - number      : 根据 flag 扩展位决定存储 int32_t(4字节) 或 double(8字节)。
119
   * - object      : 动态分配空间存储子节点,采用链表结构。
120
     *
121
     * 设计考量:
122
     * - malloc 在嵌入式平台的开销:
123
     *    * RTT 最小内存管理算法中,malloc 头部约 12 字节(可以考虑tlsf算法头部空间仅4字节,内存碎片也控制的很好,适合物联网应用)。
124
     *    * 一个 RyanJson 节点本身可能只有个位数字节,头部空间就让内存占用翻倍。
125
     * - 因此:
126
     *    * 小数据尽量 inline 存储,避免二次 malloc。
127
     *    * 大数据 fallback 到 ptr 模式,保证灵活性。
128
     * - 修改场景:
129
     *    * 理想情况:节点结构体后面直接跟 key/strValue,修改时释放并重新申请节点。
130
     *    * 但这样 changKey/changStrValue 接口改动太大,用户层需要修改指针,代价高。
131
     *    * 实际策略:提供就地修改接口。
132
     *        - 若新值长度 ≤ 原有 inline 缓冲区,直接覆盖。
133
     *        - 若超过阈值,自动切换到 ptr 模式,用户层无需关心。
134
   *
135
     * 链表结构示例:
136
     *   {
137
     *       "name": "RyanJson",
138
     *   next (
139
     *       "version": "xxx",
140
     *   next (

23
 * @brief RyanJsonInlineStringSize 默认值(单位:字节,与历史版本等价)。
24
 * @details
25
 * 该宏用于计算“节点内联字符串区可用容量”(不含 flag 字节)。
26
 *
27
 * 当前实现:
28
 * rawSize = sizeof(void*) - RyanJsonFlagSize
29
 *         + sizeof(void*)
30
 *         + (RyanJsonMallocHeaderSize / 2)
31
 *         + RyanJsonFlagSize
32
 * inlineSize = RyanJsonAlign(rawSize, RyanJsonMallocAlign) - RyanJsonFlagSize
33
 *
34
 * 各项用途:
35
 * - sizeof(void*) - RyanJsonFlagSize:
36
 *   flag占用一个字节,32位4字节对齐情况下,减去flag 占用的 1 字节后,剩余部分正好是一个指针槽的净可用载荷。
37
 * - + sizeof(void*):
38
 *   char* 最少占用一个指针大小,所以再加一个指针大小
39
 * - + (RyanJsonMallocHeaderSize / 2):
40
 *   再加上半个 header 大小的补偿,内存占用和字节内联的一个平衡点
41
 * - + RyanJsonFlagSize:
42
 *   在对齐前把前面扣掉的 flag 补回,便于统一按总尺寸做 align。
43
 * - RyanJsonAlign(..., RyanJsonMallocAlign):
44
 *   将总尺寸按 RyanJsonMallocAlign 向上对齐。
45
 * - - RyanJsonFlagSize:
46
 *   对齐后再扣掉 flag,得到最终“字符串可用字节数”。
47
 *
48
 * 其中 rawSize 里的 `-RyanJsonFlagSize` 与 `+RyanJsonFlagSize` 会抵消,
49
 * 因此与历史公式完全等价:
50
 * inlineSize = RyanJsonAlign(2 * sizeof(void*) + (RyanJsonMallocHeaderSize / 2), RyanJsonMallocAlign)
51
 *            - RyanJsonFlagSize
52
 *
53
 * 32 位示例(sizeof(void*)=4, RyanJsonFlagSize=1, RyanJsonMallocAlign=4):
54
 * - RyanJsonMallocHeaderSize=8:  Align(12, 4) - 1 = 11
55
 * - RyanJsonMallocHeaderSize=12: Align(14, 4) - 1 = 15

+guidelines, with the deviations listed below. Compliance is checked with +Coverity static analysis version 2023.6.1. Since the FreeRTOS kernel is +designed for small-embedded devices, it needs to have a very small memory +footprint and has to be efficient. To achieve that and to increase the +performance, it deviates from some MISRA rules. The specific deviations, +suppressed inline, are listed below. + +Additionally, [MISRA configuration file](examples/coverity/coverity_misra.config) +contains project wide deviations. + +### Suppressed with Coverity Comments +To find the violation references in the source files run grep on the source code +with ( Assuming rule 8.4 violation; with justification in point 1 ): +``` +grep 'MISRA Ref 8.4.1' . -rI +``` + +#### Dir 4.7 +MISRA C:2012 Dir 4.7: If a function returns error information, then that error +information shall be tested. + +_Ref 4.7.1_ + - `taskENTER_CRITICAL_FROM_ISR` returns the interrupt mask and not any error + information.

Even if the casting produces a correctly + aligned pointer, the behavior may be still undefined if the pointer is + used to access an object. FreeRTOS deliberately creates external aliases + for all the kernel object types (StaticEventGroup_t, StaticQueue_t, + StaticStreamBuffer_t, StaticTimer_t and StaticTask_t) for data hiding + purposes.

See the +[FreeRTOS Kernel Quick Start Guide](https://www.freertos.org/Documentation/01-FreeRTOS-quick-start/01-Beginners-guide/02-Quick-start-guide) +for detailed instructions and other useful links. + +Additionally, for FreeRTOS kernel feature information refer to the +[Developer Documentation](https://www.freertos.org/Documentation/02-Kernel/02-Kernel-features/00-Developer-docs), +and [API Reference](https://www.freertos.org/Documentation/02-Kernel/04-API-references/01-Task-creation/00-TaskHandle). + +Also for contributing and creating a Pull Request please refer to +[the instructions here](.github/CONTRIBUTING.md#contributing-via-pull-request). + +**FreeRTOS-Kernel V11.1.0 +[source code](https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/V11.1.0) is part +of the +[FreeRTOS 202406.00 LTS](https://github.com/FreeRTOS/FreeRTOS-LTS/tree/202406-LTS) +release.** + +### Getting help + +If you have any questions or need assistance troubleshooting your FreeRTOS project, +we have an active community that can help on the +[FreeRTOS Community Support Forum](https://forums.freertos.org). + +## To consume FreeRTOS-Kernel + +### Consume with CMake + +If using CMake, it is recommended to use this repository using FetchContent. +Add the following into your project's main or a subdirectory's `CMakeLists.txt`: + +- Define the source and version/tag you want to use: + +```cmake +FetchContent_Declare( freertos_kernel + GIT_REPOSITORY https://github.com/FreeRTOS/FreeRTOS-Kernel.git + GIT_TAG main #Note: Best practice to use specific git-hash or tagged version +) +``` + +In case you prefer to add it as a git submodule, do: + +```bash +git submodule add https://github.com/FreeRTOS/FreeRTOS-Kernel.git +git submodule update --init +``` + +- Add a freertos_config library (typically an INTERFACE library) The following assumes the directory structure: + - `include/FreeRTOSConfig.h` + +```cmake +add_library(freertos_config INTERFACE) + +target_include_directories(freertos_config SYSTEM +INTERFACE + include +) + +target_compile_definitions(freertos_config + INTERFACE + projCOVERAGE_TEST=0 +) +``` + +In case you installed FreeRTOS-Kernel as a submodule, you will have to add it as a subdirectory: + +```cmake +add_subdirectory(${FREERTOS_PATH}) +``` + +- Configure the FreeRTOS-Kernel and make it available + - this particular example supports a native and cross-compiled build option. + +```cmake +set( FREERTOS_HEAP "4" CACHE STRING "" FORCE) +# Select the native compile PORT +set( FREERTOS_PORT "GCC_POSIX" CACHE STRING "" FORCE) +# Select the cross-compile PORT +if (CMAKE_CROSSCOMPILING) + set(FREERTOS_PORT "GCC_ARM_CA9" CACHE STRING "" FORCE) +endif() + +FetchContent_MakeAvailable(freertos_kernel) +``` + +- In case of cross compilation, you should also add the following to `freertos_config`: + +```cmake +target_compile_definitions(freertos_config INTERFACE ${definitions}) +target_compile_options(freertos_config INTERFACE ${options}) +``` + +### Consuming stand-alone - Cloning this repository + +To clone using HTTPS: + +``` +git clone https://github.com/FreeRTOS/FreeRTOS-Kernel.git +``` + +Using SSH: + +``` +git clone git@github.com:FreeRTOS/FreeRTOS-Kernel.git +``` + +## Repository structure + +- The root of this repository contains the three files that are common to +every port - list.c, queue.c and tasks.c. The kernel is contained within these +three files. croutine.c implements the optional co-routine functionality - which +is normally only used on very memory limited systems. + +- The ```./portable``` directory contains the files that are specific to a particular microcontroller and/or compiler. +See the readme file in the ```./portable``` directory for more information. + +- The ```./include``` directory contains the real time kernel header files. + +- The ```./template_configuration``` directory contains a sample `FreeRTOSConfig.h` to help jumpstart a new project. +See the [FreeRTOSConfig.h](examples/template_configuration/FreeRTOSConfig.h) file for instructions. + +### Code Formatting + +FreeRTOS files are formatted using the +"[uncrustify](https://github.com/uncrustify/uncrustify)" tool. +The configuration file used by uncrustify can be found in the +[FreeRTOS/CI-CD-GitHub-Actions's](https://github.com/FreeRTOS/CI-CD-Github-Actions) +[uncrustify.cfg](https://github.com/FreeRTOS/CI-CD-Github-Actions/tree/main/formatting) +file. + +### Line Endings + +File checked into the FreeRTOS-Kernel repository use unix-style LF line endings +for the best compatibility with git. + +For optimal compatibility with Microsoft Windows tools, it is best to enable +the git autocrlf feature. You can enable this setting for the current +repository using the following command: + +``` +git config core.autocrlf true +``` + +### Git History Optimizations + +Some commits in this repository perform large refactors which touch many lines +and lead to unwanted behavior when using the `git blame` command. You can +configure git to ignore the list of large refactor commits in this repository +with the following command: + +``` +git config blame.ignoreRevsFile .git-blame-ignore-revs +``` + +### Spelling and Formatting + +We recommend using [Visual Studio Code](https://code.visualstudio.com), +commonly referred to as VSCode, when working on the FreeRTOS-Kernel. +The FreeRTOS-Kernel also uses [cSpell](https://cspell.org/) as part of its +spelling check. The config file for which can be found at [cspell.config.yaml](cspell.config.yaml) +There is additionally a +[cSpell plugin for VSCode](https://marketplace.visualstudio.com/items?itemName=streetsidesoftware.code-spell-checker) +that can be used as well. +*[.cSpellWords.txt](.github/.cSpellWords.txt)* contains words that are not +traditionally found in an English dictionary. It is used by the spellchecker +to verify the various jargon, variable names, and other odd words used in the +FreeRTOS code base are correct. If your pull request fails to pass the spelling +and you believe this is a mistake, then add the word to +*[.cSpellWords.txt](.github/.cSpellWords.txt)*. When adding a word please +then sort the list, which can be done by running the bash command: +`sort -u .cSpellWords.txt -o .cSpellWords.txt` +Note that only the FreeRTOS-Kernel Source Files, [include](include), +[portable/MemMang](portable/MemMang), and [portable/Common](portable/Common) +files are checked for proper spelling, and formatting at this time. + +## Third Party Tools +Visit [this link](.github/third_party_tools.md) for detailed information about +third-party tools with FreeRTOS support. diff --git a/test/externalModule/FreeRTOS-Kernel/croutine.c b/test/externalModule/FreeRTOS-Kernel/croutine.c new file mode 100644 index 0000000..0ce89ae --- /dev/null +++ b/test/externalModule/FreeRTOS-Kernel/croutine.c @@ -0,0 +1,405 @@ +/* + * FreeRTOS Kernel + * Copyright (C) 2021 Amazon.com, Inc. or its affiliates.

    + +__Port for generalised Microchip ATmega architecture__ + +

    Description

    + +This port provides a basis for supporting all modern ATmega devices using either the Enhanced Watchdog Timer, or Timer0 (an 8-bit Timer generally available across the whole range). + +This initial commit contains the information required to build with System Tick being generated by either the: +- Watchdog Timer, or +- Timer0 - an 8-bit Timer, or +- TimerN - a 16-bit Timer which will be configured by the user. + +Further commits can add support for 16-bit Timers available on many relevant devices. The availability of these 16-bit Timers is somewhat device specific, and these complex and highly configurable Timers are often used to generate phase correct PWM timing (for example) and they would be wasted as a simple System Tick. + +The port also provides support for the 3 byte program counter devices __ATmega2560__ and __ATmega2561__. Specific to these two devices the `EIND` register need to be preserved during a context switch. Also, due to a limitation in GCC, the scheduler needs to reside in the lower 128kB of flash for both of these devices. This is achieved by adding the `.lowtext` section attribute to the function prototype. + +To build generic Microchip (AVR) ATmega support the similarities across the family must be considered, and differences respected. Some comments on the strategy follow. + +

    System Tick

    + +The Microchip (AVR) ATmega family has limited Timer and Pin capabilities, and is designed to be used in physical applications, controlling hardware with PWM and recognising level and edge voltage changes. It does this mainly through the use of 16-bit Timers (for generating phase correct PWM by up/down counting), and Pins attached to Interrupts. The 8-bit Timers are also attached to Pins, and they can be used for more simple timing tasks, requiring only a single counting direction. + +The Timers not attached to Pins (and therefore not impacting the application of the device) are some 16-bit Timers (very device dependent, eg Timer3 on 1284p), The RTC Timer, and the Watch Dog Timer. + +The Watch Dog Timer is configured identically across most of the ATmega devices. It comes in two variants. 1. Old style (eg ATmega32) which does not have an Interrupt capability, and hence on these old devices cannot be used as the System Tick. and 2. New style enhanced WDT, which can generate an Interrupt, and is available on every relevant device. + +Using the Watch Dog Timer (WDT) to generate the System Tick does not impact its use as a watch dog. It can be configured to generate a System Tick interrupt, and then one period later to Reset the device if the interrupt is not serviced. + +Configuration and usage of the WDT is covered in `` which was revised in avr-libc 2.0.0. + +Two additional WDT functions are provided in `port.c`, which extend avr-libc functions to enable the WDT Interrupt without enabling Reset `wdt_interrupt_enable()`, and to enable both the Interrupt and the Reset `wdt_interrupt_reset_enable()`. + +

    3 Byte PC Devices

    + +The ATtiny, ATmega, ATxmega families can optionally support both 3 byte PC and 3 byte RAM addresses. However, focusing on just the ATmega family only two devices have a large Flash requiring them to use 3 byte PC. These are the __ATmega2560__ and __ATmega2561__. This PR provides support for these two devices in two ways. + + - providing `portSAVE_CONTEXT()` and `portRESTORE_CONTEXT` saving both the __RAMPZ__ and __EIND__ registers. + - providing a `portTASK_FUNCTION_PROTO()` with the linker attribute `.lowtext` which is used to ensure that the scheduler and relevant functions remain in the lower 128kB of Flash. + +For devices which can support __XRAM__ and have the __RAMPZ__ register, this register is also preserved during the context switch. + +

    Interrupt Nesting

    + +The ATmega family does not support interrupt nesting, having only one interrupt priority. This means that when the Scheduler is running, interrupts are normally disabled. + +When a very time critical process is running, based on microsecond timing generated by one of the Timers, it is important to re-enable interrupts as early as possible in processing a Yield. Fortunately, this is supported through the use of the `NO_BLOCK` decorator when defining the Interrupt Service Routine. + +The `NO_BLOCK` decorator will enable the global interrupt early in the handling of an ISR (in this case for the Scheduler), and enable interrupts to be nested. Using this method, I've been able to successfully implement an [Audio Synthesiser](https://feilipu.me/2015/06/02/goldilocks-analogue-synthesizer/) with less than 83 microseconds for each cycle, whilst still running the Scheduler to handle display and input. + +Using `NO_BLOCK` is optional, and should only be done if a critical Timer should interrupt the Scheduler. + +

    Heap Management

    + +Most users of FreeRTOS will choose to manage their own heap using one of the pre-allocated heap management algorithms, but for those that choose to use `heap_3.c`, the wrappered `malloc()` method, there is an issue that needs to be addressed. + +The avr-libc library assumes that the stack will always be above the heap, and does a check for this when responding to a `malloc()` request. This is not the case when Tasks are running, as their stack is located in the early allocated heap address ranges which will be below free heap memory, and so the `malloc()` request will fail even though heap space is available. + +To avoid this issue causing `pvPort_Malloc()` to failing, the user needs to issue this tuning statement BEFORE they use the heap, or use the `xTaskCreate()` API. + +```c +if( __malloc_heap_end == 0 ) + __malloc_heap_end = (char *)(RAMEND - __malloc_margin); +``` +Unfortunately in the repository there is nowhere sensible to include this statement as it should be included early in the `main()` function. + +For devices which can support __XRAM__ the user will need to tune the location of stack and heap according to their own requirements. + +

It supports: + + * Simple CMake INTERFACE libraries, to provide the FreeRTOS-Kernel and also the individual allocator types, without copying code into the user's project. + * Running the FreeRTOS-Kernel and tasks on either core 0 or core 1, or both. + * Use of SDK synchronization primitives (such as mutexes, semaphores, queues from pico_sync) between FreeRTOS tasks and code executing on a non FreeRTOS core, or in IRQ handlers. + +Note that whilst this SMP version can be run on just a single (either) core, it is probably +more efficient to use the non SMP version in the main FreeRTOS-Kernel branch in that case. + +## Using this port + +You can copy [FreeRTOS_Kernel_import.cmake](FreeRTOS_Kernel_import.cmake) into your project, and +add the following in your `CMakeLists.txt`: + +```cmake +include(FreeRTOS_Kernel_import.cmake) +``` + +This will locate the FreeRTOS kernel if it is a direct sub-module of your project, or if you provide the +`FREERTOS_KERNEL_PATH` variable in your environment or via `-DFREERTOS_KERNEL_PATH=/path/to/FreeRTOS-Kernel` on the CMake command line. + +**NOTE:** If you are using version 1.3.1 or older of the Raspberry Pi Pico SDK then this line must appear before the +`pico_sdk_init()` and will cause FreeRTOS to be included/required in all RP2040 targets in your project. After this SDK +version, you can include the FreeRTOS-Kernel support later in your CMake build (possibly in a subdirectory) and the +FreeRTOS-Kernel support will only apply to those targets which explicitly include FreeRTOS support. + +As an alternative to the `import` statement above, you can just add this directory directly via the following (with +the same placement restrictions related to the Raspberry Pi Pico SDK version above): + +```cmake +add_subdirectory(path/to/this/directory FreeRTOS-Kernel) +``` + + +## Advanced Configuration + +Some additional `config` options are defined [here](include/rp2040_config.h) which control some low level implementation details. + +## Known Limitations + +- Tickless idle has not currently been tested, and is likely non-functional diff --git a/test/externalModule/FreeRTOS-Kernel/portable/ThirdParty/GCC/RP2040/include/freertos_sdk_config.h b/test/externalModule/FreeRTOS-Kernel/portable/ThirdParty/GCC/RP2040/include/freertos_sdk_config.h new file mode 100644 index 0000000..e14325f --- /dev/null +++ b/test/externalModule/FreeRTOS-Kernel/portable/ThirdParty/GCC/RP2040/include/freertos_sdk_config.h @@ -0,0 +1,77 @@ +/* + * FreeRTOS Kernel + * Copyright (C) 2020 Amazon.com, Inc. or its affiliates.

For the exception handler, the cause is the contents of the EXCCAUSE +* reg, and the result is -1 if handled, else the cause (still needs handling). +* For interrupt handlers, the cause is a mask of pending enabled interrupts at +* that level, and the result is the same mask with the bits for the handled +* interrupts cleared (those not cleared still need handling). This allows a test +* case to either pre-handle or override the default handling for the exception +* or interrupt level (see xtensa_vectors.S). +* +* High priority handlers (including NMI) must be coded in assembly, are always +* called by 'call0' regardless of ABI, must preserve all registers except a0, +* and must not use or modify the interrupted stack. The hook argument 'cause' +* is not passed and the result is ignored, so as not to burden the caller with +* saving and restoring a2 (it assumes only one interrupt per level - see the +* discussion in high priority interrupts in xtensa_vectors.S). The handler +* therefore should be coded to prototype 'void h(void)' even though it plugs +* into an array of handlers of prototype 'unsigned h(unsigned)'. +* +* To enable interrupt/exception hooks, compile the RTOS with '-DXT_INTEXC_HOOKS'. +* +*******************************************************************************/ + +#define XT_INTEXC_HOOK_NUM ( 1 + XCHAL_NUM_INTLEVELS + XCHAL_HAVE_NMI ) + +#ifndef __ASSEMBLER__ + typedef unsigned (* XT_INTEXC_HOOK)( unsigned cause ); + extern volatile XT_INTEXC_HOOK _xt_intexc_hooks[ XT_INTEXC_HOOK_NUM ]; +#endif + + +/******************************************************************************* +* +* CONVENIENCE INCLUSIONS. +* +* Ensures RTOS specific files need only include this one Xtensa-generic header. +* These headers are included last so they can use the RTOS definitions above. +* +*******************************************************************************/ + +#include "xtensa_context.h" + +#ifdef XT_RTOS_TIMER_INT + #include "xtensa_timer.h" +#endif + + +/******************************************************************************* +* +* Xtensa Port Version. +* +*******************************************************************************/ + +#define XTENSA_PORT_VERSION 1.4 .2 +#define XTENSA_PORT_VERSION_STRING "1.4.2" + +#endif /* XTENSA_RTOS_H */ diff --git a/test/externalModule/FreeRTOS-Kernel/portable/ThirdParty/GCC/Xtensa_ESP32/include/xtensa_timer.h b/test/externalModule/FreeRTOS-Kernel/portable/ThirdParty/GCC/Xtensa_ESP32/include/xtensa_timer.h new file mode 100644 index 0000000..2cfc809 --- /dev/null +++ b/test/externalModule/FreeRTOS-Kernel/portable/ThirdParty/GCC/Xtensa_ESP32/include/xtensa_timer.h @@ -0,0 +1,168 @@ +/* + * SPDX-FileCopyrightText: 2015-2019 Cadence Design Systems, Inc. + * + * SPDX-License-Identifier: MIT + * + * SPDX-FileContributor: 2016-2022 Espressif Systems (Shanghai) CO LTD + */ + +/* + * Copyright (c) 2015-2019 Cadence Design Systems, Inc. + * + * Permission is hereby granted, free of charge, to any person obtaining + * a copy of this software and associated documentation files (the + * "Software"), to deal in the Software without restriction, including + * without limitation the rights to use, copy, modify, merge, publish, + * distribute, sublicense, and/or sell copies of the Software, and to + * permit persons to whom the Software is furnished to do so, subject to + * the following conditions: + * + * The above copyright notice and this permission notice shall be included + * in all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, + * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF + * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. + * IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY + * CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, + * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE + * SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. + */ + +/******************************************************************************* +* +* XTENSA INFORMATION FOR RTOS TICK TIMER AND CLOCK FREQUENCY +* +* This header contains definitions and macros for use primarily by Xtensa +* RTOS assembly coded source files.

These macros are defined in + xtensa_.h to call suitable functions in a specific RTOS. + + Users can install application-specific interrupt handlers for low and + medium level interrupts, by calling xt_set_interrupt_handler(). These + handlers can be written in C, and must obey C calling convention. The + handler table is indexed by the interrupt number. Each handler may be + provided with an argument. + + Note that the system timer interrupt is handled specially, and is + dispatched to the RTOS-specific handler. This timer cannot be hooked + by application code. + + Optional hooks are also provided to install a handler per level at + run-time, made available by compiling this source file with + '-DXT_INTEXC_HOOKS' (useful for automated testing). + +!! This file is a template that usually needs to be modified to handle !! +!! application specific interrupts. Search USER_EDIT for helpful comments !! +!! on where to insert handlers and how to write them. !! + + Users can also install application-specific exception handlers in the + same way, by calling xt_set_exception_handler(). One handler slot is + provided for each exception type. Note that some exceptions are handled + by the porting layer itself, and cannot be taken over by application + code in this manner. These are the alloca, syscall, and coprocessor + exceptions. + + The exception handlers can be written in C, and must follow C calling + convention. Each handler is passed a pointer to an exception frame as + its single argument. The exception frame is created on the stack, and + holds the saved context of the thread that took the exception. If the + handler returns, the context will be restored and the instruction that + caused the exception will be retried. If the handler makes any changes + to the saved state in the exception frame, the changes will be applied + when restoring the context. + + Because Xtensa is a configurable architecture, this port supports all user + generated configurations (except restrictions stated in the release notes). + This is accomplished by conditional compilation using macros and functions + defined in the Xtensa HAL (hardware adaptation layer) for your configuration. + Only the relevant parts of this file will be included in your RTOS build. + For example, this file provides interrupt vector templates for all types and + all priority levels, but only the ones in your configuration are built. + + NOTES on the use of 'call0' for long jumps instead of 'j': + 1. This file should be assembled with the -mlongcalls option to xt-xcc. + 2. The -mlongcalls compiler option causes 'call0 dest' to be expanded to + a sequence 'l32r a0, dest' 'callx0 a0' which works regardless of the + distance from the call to the destination. The linker then relaxes + it back to 'call0 dest' if it determines that dest is within range. + This allows more flexibility in locating code without the performance + overhead of the 'l32r' literal data load in cases where the destination + is in range of 'call0'. There is an additional benefit in that 'call0' + has a longer range than 'j' due to the target being word-aligned, so + the 'l32r' sequence is less likely needed. + 3. The use of 'call0' with -mlongcalls requires that register a0 not be + live at the time of the call, which is always the case for a function + call but needs to be ensured if 'call0' is used as a jump in lieu of 'j'. + 4. This use of 'call0' is independent of the C function call ABI. + +*******************************************************************************/ + +#include "xtensa_rtos.h" +#include "esp_idf_version.h" +#if (ESP_IDF_VERSION < ESP_IDF_VERSION_VAL(4, 2, 0)) +#include "esp_panic.h" +#else +#include "esp_private/panic_reason.h" +#endif /* ESP_IDF_VERSION < ESP_IDF_VERSION_VAL(4, 2, 0) */ +#include "sdkconfig.h" +#include "soc/soc.h" + +/* + Define for workaround: pin no-cpu-affinity tasks to a cpu when fpu is used. + Please change this when the tcb structure is changed +*/ +#define TASKTCB_XCOREID_OFFSET (0x38+configMAX_TASK_NAME_LEN+3)&~3 +.extern pxCurrentTCB + +/* +-------------------------------------------------------------------------------- + In order for backtracing to be able to trace from the pre-exception stack + across to the exception stack (including nested interrupts), we need to create + a pseudo base-save area to make it appear like the exception dispatcher was + triggered by a CALL4 from the pre-exception code.

High priority +interrupts cannot interact with the RTOS, that is they must save all regs +they use and not call any RTOS function. + +A further restriction imposed by the Xtensa windowed architecture is that +high priority interrupts must not modify the stack area even logically +"above" the top of the interrupted stack (they need to provide their +own stack or static save area). + +Cadence Design Systems recommends high priority interrupt handlers be coded in assembly +and used for purposes requiring very short service times. + +Here are templates for high priority (level 2+) interrupt vectors. +They assume only one interrupt per level to avoid the burden of identifying +which interrupts at this level are pending and enabled. This allows for +minimum latency and avoids having to save/restore a2 in addition to a0. +If more than one interrupt per high priority level is configured, this burden +is on the handler which in any case must provide a way to save and restore +registers it uses without touching the interrupted stack. + +Each vector goes at a predetermined location according to the Xtensa +hardware configuration, which is ensured by its placement in a special +section known to the Xtensa linker support package (LSP).

+Welcome to the Unity Test Project, one of the main projects of ThrowTheSwitch.org. +Unity Test is a unit testing framework built for C, with a focus on working with embedded toolchains. + +This project is made to test code targetting microcontrollers big and small. +The core project is a single C file and a pair of headers, allowing it to be added to your existing build setup without too much headache. +You may use any compiler you wish, and may use most existing build systems including Make, CMake, etc. +If you'd like to leave the hard work to us, you might be interested in Ceedling, a build tool also by ThrowTheSwitch.org. + +If you're new to Unity, we encourage you to tour the [getting started guide][]. + +You can also find the [change log][] and [known issues][] in our documentation. + +## Getting Started + +The [docs][] folder contains a [getting started guide][] and much more tips about using Unity. + +## Unity Assertion Summary + +For the full list, see [UnityAssertionsReference.md][]. + +### Basic Validity Tests + + TEST_ASSERT_TRUE(condition) + +Evaluates whatever code is in condition and fails if it evaluates to false + + TEST_ASSERT_FALSE(condition) + +Evaluates whatever code is in condition and fails if it evaluates to true + + TEST_ASSERT(condition) + +Another way of calling `TEST_ASSERT_TRUE` + + TEST_ASSERT_UNLESS(condition) + +Another way of calling `TEST_ASSERT_FALSE` + + TEST_FAIL() + TEST_FAIL_MESSAGE(message) + +This test is automatically marked as a failure. +The message is output stating why. + +### Numerical Assertions: Integers + + TEST_ASSERT_EQUAL_INT(expected, actual) + TEST_ASSERT_EQUAL_INT8(expected, actual) + TEST_ASSERT_EQUAL_INT16(expected, actual) + TEST_ASSERT_EQUAL_INT32(expected, actual) + TEST_ASSERT_EQUAL_INT64(expected, actual) + +Compare two integers for equality and display errors as signed integers. +A cast will be performed to your natural integer size so often this can just be used. +When you need to specify the exact size, you can use a specific version. + + TEST_ASSERT_EQUAL_UINT(expected, actual) + TEST_ASSERT_EQUAL_UINT8(expected, actual) + TEST_ASSERT_EQUAL_UINT16(expected, actual) + TEST_ASSERT_EQUAL_UINT32(expected, actual) + TEST_ASSERT_EQUAL_UINT64(expected, actual) + +Compare two integers for equality and display errors as unsigned integers. +Like INT, there are variants for different sizes also. + + TEST_ASSERT_EQUAL_HEX(expected, actual) + TEST_ASSERT_EQUAL_HEX8(expected, actual) + TEST_ASSERT_EQUAL_HEX16(expected, actual) + TEST_ASSERT_EQUAL_HEX32(expected, actual) + TEST_ASSERT_EQUAL_HEX64(expected, actual) + +Compares two integers for equality and display errors as hexadecimal. +Like the other integer comparisons, you can specify the size... +here the size will also affect how many nibbles are shown (for example, `HEX16` will show 4 nibbles). + + TEST_ASSERT_EQUAL(expected, actual) + +Another way of calling TEST_ASSERT_EQUAL_INT + + TEST_ASSERT_INT_WITHIN(delta, expected, actual) + +Asserts that the actual value is within plus or minus delta of the expected value. +This also comes in size specific variants. + + TEST_ASSERT_GREATER_THAN(threshold, actual) + +Asserts that the actual value is greater than the threshold. +This also comes in size specific variants. + + TEST_ASSERT_LESS_THAN(threshold, actual) + +Asserts that the actual value is less than the threshold. +This also comes in size specific variants. + +### Arrays + + _ARRAY + +You can append `_ARRAY` to any of these macros to make an array comparison of that type. +Here you will need to care a bit more about the actual size of the value being checked. +You will also specify an additional argument which is the number of elements to compare. +For example: + + TEST_ASSERT_EQUAL_HEX8_ARRAY(expected, actual, elements) + + _EACH_EQUAL + +Another array comparison option is to check that EVERY element of an array is equal to a single expected value. +You do this by specifying the EACH_EQUAL macro. +For example: + + TEST_ASSERT_EACH_EQUAL_INT32(expected, actual, elements) + +### Numerical Assertions: Bitwise + + TEST_ASSERT_BITS(mask, expected, actual) + +Use an integer mask to specify which bits should be compared between two other integers. +High bits in the mask are compared, low bits ignored. + + TEST_ASSERT_BITS_HIGH(mask, actual) + +Use an integer mask to specify which bits should be inspected to determine if they are all set high. +High bits in the mask are compared, low bits ignored. + + TEST_ASSERT_BITS_LOW(mask, actual) + +Use an integer mask to specify which bits should be inspected to determine if they are all set low. +High bits in the mask are compared, low bits ignored. + + TEST_ASSERT_BIT_HIGH(bit, actual) + +Test a single bit and verify that it is high. +The bit is specified 0-31 for a 32-bit integer. + + TEST_ASSERT_BIT_LOW(bit, actual) + +Test a single bit and verify that it is low. +The bit is specified 0-31 for a 32-bit integer. + +### Numerical Assertions: Floats + + TEST_ASSERT_FLOAT_WITHIN(delta, expected, actual) + TEST_ASSERT_DOUBLE_WITHIN(delta, expected, actual) + +Asserts that the actual value is within plus or minus delta of the expected value. + + TEST_ASSERT_FLOAT_NOT_WITHIN(delta, expected, actual) + TEST_ASSERT_DOUBLE_NOT_WITHIN(delta, expected, actual) + +Asserts that the actual value is NOT within plus or minus delta of the expected value. + + TEST_ASSERT_EQUAL_FLOAT(expected, actual) + TEST_ASSERT_EQUAL_DOUBLE(expected, actual) + +Asserts that two floating point values are "equal" within a small % delta of the expected value. + + TEST_ASSERT_NOT_EQUAL_FLOAT(expected, actual) + TEST_ASSERT_NOT_EQUAL_DOUBLE(expected, actual) + +Asserts that two floating point values are NOT "equal" within a small % delta of the expected value. + + TEST_ASSERT_LESS_THAN_FLOAT(threshold, actual) + TEST_ASSERT_LESS_THAN_DOUBLE(threshold, actual) + TEST_ASSERT_GREATER_THAN_FLOAT(threshold, actual) + TEST_ASSERT_GREATER_THAN_DOUBLE(threshold, actual) + +Asserts that the actual value is less than or greater than the threshold. + +There are also `LESS_OR_EQUAL` and `GREATER_OR_EQUAL` variations. +These obey the same rules for equality as do `TEST_ASSERT_EQUAL_FLOAT` and `TEST_ASSERT_EQUAL_DOUBLE`: +If the two values are within a small % delta of the expected value, the assertion will pass. + +### String Assertions + + TEST_ASSERT_EQUAL_STRING(expected, actual) + +Compare two null-terminate strings. +Fail if any character is different or if the lengths are different. + + TEST_ASSERT_EQUAL_STRING_LEN(expected, actual, len) + +Compare two strings. +Fail if any character is different, stop comparing after len characters. + + TEST_ASSERT_EQUAL_STRING_MESSAGE(expected, actual, message) + +Compare two null-terminate strings. +Fail if any character is different or if the lengths are different. +Output a custom message on failure. + + TEST_ASSERT_EQUAL_STRING_LEN_MESSAGE(expected, actual, len, message) + +Compare two strings. +Fail if any character is different, stop comparing after len characters. +Output a custom message on failure. + +### Pointer Assertions + +Most pointer operations can be performed by simply using the integer comparisons above. +However, a couple of special cases are added for clarity. + + TEST_ASSERT_NULL(pointer) + +Fails if the pointer is not equal to NULL + + TEST_ASSERT_NOT_NULL(pointer) + +Fails if the pointer is equal to NULL + +### Memory Assertions + + TEST_ASSERT_EQUAL_MEMORY(expected, actual, len) + +Compare two blocks of memory. +This is a good generic assertion for types that can't be coerced into acting like standard types... +but since it's a memory compare, you have to be careful that your data types are packed. + +### \_MESSAGE + +You can append `\_MESSAGE` to any of the macros to make them take an additional argument. +This argument is a string that will be printed at the end of the failure strings. +This is useful for specifying more information about the problem. + +[CI]: https://github.com/ThrowTheSwitch/Unity/workflows/CI/badge.svg +[getting started guide]: docs/UnityGettingStartedGuide.md +[change log]:
