UART_HandleTypeDef huart). + (#) Initialize the UART low level resources by implementing the HAL_UART_MspInit() API: + (##) Enable the USARTx interface clock. + (##) UART pins configuration: + (+++) Enable the clock for the UART GPIOs. + (+++) Configure the UART TX/RX pins as alternate function pull-up. + (##) NVIC configuration if you need to use interrupt process (HAL_UART_Transmit_IT() + and HAL_UART_Receive_IT() APIs): + (+++) Configure the USARTx interrupt priority. + (+++) Enable the NVIC USART IRQ handle. + (##) DMA Configuration if you need to use DMA process (HAL_UART_Transmit_DMA() + and HAL_UART_Receive_DMA() APIs): + (+++) Declare a DMA handle structure for the Tx/Rx stream. + (+++) Enable the DMAx interface clock. + (+++) Configure the declared DMA handle structure with the required + Tx/Rx parameters. + (+++) Configure the DMA Tx/Rx stream. + (+++) Associate the initialized DMA handle to the UART DMA Tx/Rx handle. + (+++) Configure the priority and enable the NVIC for the transfer complete + interrupt on the DMA Tx/Rx stream. + (+++) Configure the USARTx interrupt priority and enable the NVIC USART IRQ handle + (used for last byte sending completion detection in DMA non circular mode) + + (#) Program the Baud Rate, Word Length, Stop Bit, Parity, Hardware + flow control and Mode(Receiver/Transmitter) in the huart Init structure. + + (#) For the UART asynchronous mode, initialize the UART registers by calling + the HAL_UART_Init() API. + + (#) For the UART Half duplex mode, initialize the UART registers by calling + the HAL_HalfDuplex_Init() API. + + (#) For the LIN mode, initialize the UART registers by calling the HAL_LIN_Init() API. + + (#) For the Multi-Processor mode, initialize the UART registers by calling + the HAL_MultiProcessor_Init() API. + + [..] + (@) The specific UART interrupts (Transmission complete interrupt, + RXNE interrupt and Error Interrupts) will be managed using the macros + __HAL_UART_ENABLE_IT() and __HAL_UART_DISABLE_IT() inside the transmit + and receive process. + + [..] + (@) These APIs (HAL_UART_Init() and HAL_HalfDuplex_Init()) configure also the + low level Hardware GPIO, CLOCK, CORTEX...etc) by calling the customized + HAL_UART_MspInit() API. + + ##### Callback registration ##### + ================================== + + [..] + The compilation define USE_HAL_UART_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + + [..] + Use Function HAL_UART_RegisterCallback() to register a user callback. + Function HAL_UART_RegisterCallback() allows to register following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) MspInitCallback : UART MspInit. + (+) MspDeInitCallback : UART MspDeInit. + This function takes as parameters the HAL peripheral handle, the Callback ID + and a pointer to the user callback function. + + [..] + Use function HAL_UART_UnRegisterCallback() to reset a callback to the default + weak (surcharged) function. + HAL_UART_UnRegisterCallback() takes as parameters the HAL peripheral handle, + and the Callback ID. + This function allows to reset following callbacks: + (+) TxHalfCpltCallback : Tx Half Complete Callback. + (+) TxCpltCallback : Tx Complete Callback. + (+) RxHalfCpltCallback : Rx Half Complete Callback. + (+) RxCpltCallback : Rx Complete Callback. + (+) ErrorCallback : Error Callback. + (+) AbortCpltCallback : Abort Complete Callback. + (+) AbortTransmitCpltCallback : Abort Transmit Complete Callback. + (+) AbortReceiveCpltCallback : Abort Receive Complete Callback. + (+) MspInitCallback : UART MspInit. + (+) MspDeInitCallback : UART MspDeInit. + + [..] + For specific callback RxEventCallback, use dedicated registration/reset functions: + respectively HAL_UART_RegisterRxEventCallback() , HAL_UART_UnRegisterRxEventCallback(). + + [..] + By default, after the HAL_UART_Init() and when the state is HAL_UART_STATE_RESET + all callbacks are set to the corresponding weak (surcharged) functions: + examples HAL_UART_TxCpltCallback(), HAL_UART_RxHalfCpltCallback(). + Exception done for MspInit and MspDeInit functions that are respectively + reset to the legacy weak (surcharged) functions in the HAL_UART_Init() + and HAL_UART_DeInit() only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the HAL_UART_Init() and HAL_UART_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_UART_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_UART_STATE_READY or HAL_UART_STATE_RESET state, thus registered (user) + MspInit/DeInit callbacks can be used during the Init/DeInit. + In that case first register the MspInit/MspDeInit user callbacks + using HAL_UART_RegisterCallback() before calling HAL_UART_DeInit() + or HAL_UART_Init() function. + + [..] + When The compilation define USE_HAL_UART_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available + and weak (surcharged) callbacks are used. + + [..]

Otherwise the CMSIS-RTOS implementation is no longer +compliant to the standard. Note that some functions are optional and need not to be provided by every CMSIS-RTOS implementation. + + +Function calls from interrupt service routines + +The following CMSIS-RTOS functions can be called from threads and interrupt service routines (ISR): + - \ref osSignalSet + - \ref osSemaphoreRelease + - \ref osPoolAlloc, \ref osPoolCAlloc, \ref osPoolFree + - \ref osMessagePut, \ref osMessageGet + - \ref osMailAlloc, \ref osMailCAlloc, \ref osMailGet, \ref osMailPut, \ref osMailFree + +Functions that cannot be called from an ISR are verifying the interrupt status and return in case that they are called +from an ISR context the status code \b osErrorISR. In some implementations this condition might be caught using the HARD FAULT vector. + +Some CMSIS-RTOS implementations support CMSIS-RTOS function calls from multiple ISR at the same time. +If this is impossible, the CMSIS-RTOS rejects calls by nested ISR functions with the status code \b osErrorISRRecursive. + + +Define and reference object definitions + +With \#define osObjectsExternal objects are defined as external symbols. This allows to create a consistent header file +that is used throughout a project as shown below: + +Header File +\code +#include // CMSIS RTOS header file + +// Thread definition +extern void thread_sample (void const *argument); // function prototype +osThreadDef (thread_sample, osPriorityBelowNormal, 1, 100); + +// Pool definition +osPoolDef(MyPool, 10, long); +\endcode + + +This header file defines all objects when included in a C/C++ source file. When \#define osObjectsExternal is +present before the header file, the objects are defined as external symbols.

+ * interrupt that will read from the buffer (the reader).  It is safe for the
+ * writer and reader to be different tasks or interrupts, but, unlike other
+ * FreeRTOS objects, it is not safe to have multiple different writers or
+ * multiple different readers.  If there are to be multiple different writers
+ * then the application writer must place each call to a writing API function
+ * (such as xMessageBufferSend()) inside a critical section and set the send
+ * block time to 0.  Likewise, if there are to be multiple different readers
+ * then the application writer must place each call to a reading API function
+ * (such as xMessageBufferRead()) inside a critical section and set the receive
+ * block time to 0.
+ *
+ * Use xMessageBufferSend() to write to a message buffer from a task.  Use
+ * xMessageBufferSendFromISR() to write to a message buffer from an interrupt
+ * service routine (ISR).
+ *
+ * @param xMessageBuffer The handle of the message buffer to which a message is
+ * being sent.
+ *
+ * @param pvTxData A pointer to the message that is to be copied into the
+ * message buffer.
+ *
+ * @param xDataLengthBytes The length of the message.  That is, the number of
+ * bytes to copy from pvTxData into the message buffer.  When a message is
+ * written to the message buffer an additional sizeof( size_t ) bytes are also
+ * written to store the message's length.  sizeof( size_t ) is typically 4 bytes
+ * on a 32-bit architecture, so on most 32-bit architecture setting
+ * xDataLengthBytes to 20 will reduce the free space in the message buffer by 24
+ * bytes (20 bytes of message data and 4 bytes to hold the message length).
+ *
+ * @param pxHigherPriorityTaskWoken  It is possible that a message buffer will
+ * have a task blocked on it waiting for data.  Calling
+ * xMessageBufferSendFromISR() can make data available, and so cause a task that
+ * was waiting for data to leave the Blocked state.  If calling
+ * xMessageBufferSendFromISR() causes a task to leave the Blocked state, and the
+ * unblocked task has a priority higher than the currently executing task (the
+ * task that was interrupted), then, internally, xMessageBufferSendFromISR()
+ * will set *pxHigherPriorityTaskWoken to pdTRUE.  If
+ * xMessageBufferSendFromISR() sets this value to pdTRUE, then normally a
+ * context switch should be performed before the interrupt is exited.  This will
+ * ensure that the interrupt returns directly to the highest priority Ready
+ * state task.  *pxHigherPriorityTaskWoken should be set to pdFALSE before it
+ * is passed into the function.  See the code example below for an example.
+ *

Likewise, if there are to be multiple different readers + * then the application writer must place each call to a reading API function + * (such as xMessageBufferRead()) inside a critical section and set the receive + * timeout to 0. + * + * Message buffers hold variable length messages. To enable that, when a + * message is written to the message buffer an additional sizeof( size_t ) bytes + * are also written to store the message's length (that happens internally, with + * the API function). sizeof( size_t ) is typically 4 bytes on a 32-bit + * architecture, so writing a 10 byte message to a message buffer on a 32-bit + * architecture will actually reduce the available space in the message buffer + * by 14 bytes (10 byte are used by the message, and 4 bytes to hold the length + * of the message). + */ + +#ifndef FREERTOS_MESSAGE_BUFFER_H +#define FREERTOS_MESSAGE_BUFFER_H + +#ifndef INC_FREERTOS_H + #error "include FreeRTOS.h must appear in source files before include message_buffer.h" +#endif + +/* Message buffers are built onto of stream buffers. */ +#include "stream_buffer.h" + +/* *INDENT-OFF* */ +#if defined( __cplusplus ) + extern "C" { +#endif +/* *INDENT-ON* */ + +/** + * Type by which message buffers are referenced.

z180 support

+ +Description +----------- +This PR establishes support for a Zilog z180 port, using the Programmable Reload Timer 1, configured at 256 Hz. + +Because of the generality of the z180, the address of the Interrupt Vector for PRT1 is configurable, and must be configured by the `crt0.asm` outside of this port. A configuration assumption has been made. + +The two compilers ([used by the z88dk](https://github.com/z88dk/z88dk)) are supported. The sccz80 compiler and the sdcc compiler. The PR is located under Z88dk. + +Background +----------- +This PR is based on running code for the [SC130](https://smallcomputercentral.wordpress.com/sc130-z180-motherboard/)/[SC131](https://smallcomputercentral.wordpress.com/sc131-z180-pocket-computer/) and [YAZ180](https://github.com/feilipu/yaz180) platforms, and is maintained by the z88dk team in this [z88dk-libraries](https://github.com/feilipu/z88dk-libraries/tree/master/freertos) repository. diff --git a/tutorial01-stm32-pio-01/pio-01-02_olivia/portable/ThirdParty/GCC/ARC_EM_HS/arc_freertos_exceptions.c b/tutorial01-stm32-pio-01/pio-01-02_olivia/portable/ThirdParty/GCC/ARC_EM_HS/arc_freertos_exceptions.c new file mode 100644 index 0000000..8ffe40b --- /dev/null +++ b/tutorial01-stm32-pio-01/pio-01-02_olivia/portable/ThirdParty/GCC/ARC_EM_HS/arc_freertos_exceptions.c @@ -0,0 +1,52 @@ +/* + * FreeRTOS Kernel V10.5.1 + * Copyright (C) 2020 Synopsys, Inc. or its affiliates.

This port is supported by TF-M version **tag: TF-Mv1.5.0** & **tag: TF-Mv1.6.0**. + +### Build TF-M + +Please refer to this [link](https://tf-m-user-guide.trustedfirmware.org/docs/technical_references/instructions/tfm_build_instruction.html) to build the secure side. +_**Note:** ```TFM_NS_MANAGE_NSID``` must be configured as "OFF" when building TF-M_. + +## Build the Non-Secure Side + +Please copy all the files in ```freertos_kernel\portable\GCC\ARM_CM[23|33|55|85]_NTZ``` into the ```freertos_kernel\portable\ThirdParty\GCC\ARM_TFM``` folder before using this port. Note that TrustZone is enabled in this port. The TF-M runs in the Secure Side. + +Please call the API ```tfm_ns_interface_init()``` which is defined in ```\app\tfm_ns_interface.c``` by tf-m-tests +(tag: TF-Mv1.5.0 & TF-Mv1.6.0) at the very beginning of your application. Otherwise, it will always fail when calling a TF-M service in the Nonsecure Side. + +### Configuration in FreeRTOS kernel + +* ```configRUN_FREERTOS_SECURE_ONLY``` +This macro should be configured as 0. In this port, TF-M runs in the Secure Side while FreeRTOS +Kernel runs in the Non-Secure Side. + +* ```configENABLE_FPU``` +The setting of this macro is decided by the setting in Secure Side which is platform-specific. +If the Secure Side enables Non-Secure access to FPU, then this macro can be configured as 0 or 1. Otherwise, this macro can only be configured as 0. +Please note that Cortex-M23 does not support FPU. +Please refer to [TF-M documentation](https://tf-m-user-guide.trustedfirmware.org/integration_guide/tfm_fpu_support.html) for FPU usage on the Non-Secure side. + +* ```configENABLE_MVE``` +The setting of this macro is decided by the setting in Secure Side which is platform-specific. +If the Secure Side enables Non-Secure access to MVE, then this macro can be configured as 0 or 1. Otherwise, this macro can only be configured as 0. +Please note that only Cortex-M55 and Cortex-M85 support MVE. +Please refer to [TF-M documentation](https://tf-m-user-guide.trustedfirmware.org/integration_guide/tfm_fpu_support.html) for MVE usage on the Non-Secure side. + +* ```configENABLE_TRUSTZONE``` +This macro should be configured as 0 because TF-M doesn't use the secure context management function of FreeRTOS. New secure context management might be introduced when TF-M supports multiple secure context. + + +### Integrate TF-M Non-Secure interface with FreeRTOS project + +To enable calling TF-M services by the Non-Secure Side, the files below should be included in the FreeRTOS project and built together. +* files in ```trusted-firmware-m\build\install\interface\src``` + These files contain the implementation of PSA Functional Developer APIs which can be called by Non-Secure Side directly and PSA Firmware Framework APIs in the IPC model. These files should be taken as part of the Non-Secure source code. +* files in ```trusted-firmware-m\build\install\interface\include``` + These files are the necessary header files to call TF-M services. +* ```trusted-firmware-m\build\install\interface\lib\s_veneers.o``` + This object file contains all the Non-Secure callable functions exported by + TF-M and it should be linked when generating the Non-Secure image. + + + +*Copyright (c) 2020-2022, Arm Limited.

ATmegaxxxx

+ +__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. + +

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).

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.

This port supports all of them, including custom processor +extensions defined in the TIE language, with certain minimum +requirements. You must use Xtensa Tools to compile and link FreeRTOS and +your application for your Xtensa configuration. The port uses the Xtensa +Hardware Abstraction Layer (HAL) to adapt to your Xtensa configuration. +NOTE: It may be possible to build and run this with the open-source +xtensa-linux tools provided you have the correct overlay for your Xtensa +configuration. However, this has not been tested and is currently not +supported by Cadence. + +This port includes optional reentrancy support for the 'newlib' and +'xclib' C runtime libraries distributed with Xtensa Tools, providing +thread-safety on a per task basis (for use in tasks only, not interrupt +handlers). + +NOTE: At this time only 'newlib' and 'xclib' C libraries are supported +for thread safety. The 'uclibc' library is not reentrant and does not +provide thread safety at this time. However, if you are not concerned +with reentrancy then you can use any of these libraries. + +This port also includes a simple example application that may run on +a supported board or the Xtensa instruction set simulator (ISS). There +are also a couple of test programs used in maintaining the port, which +serve as additional examples. + +FreeRTOS for Xtensa configurable processors requires the following minimum +processor configuration options: +- Timer interrupt option with at least one interruptible timer. +- Interrupt option (implied by the timer interrupt option). +- Exception Architecture 2 (XEA2). Please note that XEA1 is NOT supported. + All 'Diamond', 'Xtensa 6', 'Xtensa LX' and 'Xtensa LX2' processors and + most 'Xtensa T1050' processors are configured with XEA2. +All Diamond processor cores meet these requirements and are supported. + +Minimal support for certain evaluation boards is provided via a board +independent XTBSP API implemented by a board specific library distributed +with the Xtensa Tools. This provides the board clock frequency and basic +polled drivers for the display and console device. Note that XTBSP +is not a tradtional RTOS "board support package" with RTOS specific +interrupt-driven drivers - it is not specific to any RTOS. Note that +FreeRTOS can run on any Xtensa or Diamond board without this board support +(a "raw" platform), but you will have to provide the clock frequency +and drivers for any on-board devices you want to use. + + +Installation +------------ + +The Xtensa port of FreeRTOS is available at this location: + + https://github.com/foss-xtensa/amazon-freertos + +This download includes the core FreeRTOS source and include files needed +to build the port. You can also download the official release of FreeRTOS +version 1.0.0 or later from this location: + + https://github.com/aws/amazon-freertos + +The Xtensa port files are currently not included in the official package. + +All source is provided along with a Makefile that works for any host +platform supported by Xtensa Tools (Windows, Linux). These instructions +are written for Windows users, but can easily be understood and adapted +to other host platforms. + +First install the FreeRTOS common package in a directory of your choosing. +The structure of that package will look like this: + + +|-- demos +| `-- cadence +| `-- sim +| |-- common +| | |-- application_code +| | | `-- cadence_code +| | `-- config_files +| `-- xplorer +`-- lib + |-- FreeRTOS + | `-- portable + | |-- Common + | |-- MemMang + | `-- XCC + | `-- Xtensa + `-- include + `-- private + +The Xtensa Tools are available from Cadence as part of a processor +license. Be sure you have installed the Xtensa Tools and your processor +configuration. + + +Building FreeRTOS for Xtensa +---------------------------- + +To build the FreeRTOS library and the example programs, go into the +directory 'demos/cadence/sim' and use the makefile in that directory. +"make all" will build all the examples. There is another makefile in +the 'lib/FreeRTOS/portable/XCC/Xtensa' directory that builds just the +FreeRTOS library. + +By default, you will build for the Xtensa instruction set simulator. If +you have a supported emulation board, you can build to run on that. You +can also build to run on a raw Xtensa core with no board support, a +good starting point for supporting your own target platform. Cadence +recommends doing functional development on the simulator because it +is easier to debug with, then move to a board if/when you need to test +hardware drivers or real-time performance. + +The provided makefile simplifies building FreeRTOS and the example +for your Xtensa configuration and platform (ISS, board, etc.). There +are detailed instructions in the comments at the top of the makefile. + +The makefiles work on Windows and Linux and support incremental builds. +The build for each Xtensa configuration and target platform is placed in +a subdirectory so several core and platform builds can co-exist even with +incremental rebuilds. You may specify the root of the build area (if tou +want it to be elsewhere than under the source tree) by defining BLDROOT +either in the make command or your shell environment. + + +Building the FreeRTOS Library +----------------------------- + +First, be sure you have installed Xtensa Tools and your processor +configuration, and be sure that Xtensa Tools are in your search path. +You can use xt-make, which comes with the Xtensa Tools, to run the +makefiles. + +Change directories to the Xtensa port directory: + +> cd lib/FreeRTOS/portable/XCC/Xtensa + +Now build the FreeRTOS RTOS as a library (libfreertos.a) as follows: + +> xt-make + +which by default builds for the simulator (TARGET=sim), or: + +> xt-make TARGET=board + +which builds for a supported board. Note that the board type does not +need to be specified when building the FreeRTOS library. + +If you are building for an Xtensa processor configuration that is not the +default you selected when you installed Xtensa Tools, you need to define the +environment variable XTENSA_CORE. If your configuration is not in the +default registry you selected when you installed Xtensa Tools, you also +need to define the environment variable XTENSA_SYSTEM. See tools manuals. +You can avoid defining these in your environment if you pass the variables +you need to redefine into xt-make as follows: + +> xt-make XTENSA_CORE= XTENSA_SYSTEM= ... + +There are more details about build options in the comment in the Makefile. + +After the library has been built, you must link your application with this +library in order to use FreeRTOS. + + +Building the FreeRTOS Examples +------------------------------ + +The provided examples are designed to run on the Xtensa instruction set +simulator (ISS) or a supported evaluation board programmed with your +Xtensa processor configuration. + +To build the examples for the default platform (simulator): + +> cd demos/cadence/sim + +> xt-make all + +which is the same as + +> xt-make all TARGET=sim + +The boards currently supported are the Xilinx ML605 and KC705 FPGA +development boards. To target these boards, type + +> xt-make all TARGET=ml605 + +or + +> xt-make all TARGET=kc705 + +To build in a location other than the default, specify the new location +using the BLDROOT variable. Note that this makefile will invoke the +FreeRTOS library build makefile automatically, passing on the relevant +parameters based on what you specified. + +You can override the default compilation options by specifying the new +options via CFLAGS. For example: + +> xt-make all TARGET=sim CFLAGS="-O2 -Os -g" + +This compiles the examples and links them with the FreeRTOS library +libfreertos.a and the appropriate linker-support package (LSP) for your +target platform (you can override the LSP by adding LSP= to the +xt-make command line). The resulting ELF files can be downloaded and +executed on the target. The example binaries appear in the platform +specific subdirectory described earlier. + +To build your application with thread-safe C library support, you +need to make certain modifications to the application to plug in and +invoke the reentrancy support. This allows each task to use the library +without interference with other tasks (it is not safe for interrupt +handlers to call the C library). + +First, you must define + + XT_USE_THREAD_SAFE_CLIB + +to a nonzero value either in xtensa_config.h or on the compiler's command +line. Note that the default xtensa_config.h provided with this port does +define this to 1 if either newlib or xclib is detected. + +Then, you must also make sure to allocate extra space on the stack for +each task that will use the C library reentrant functions. This extra +space is to be allocated over and above the actual stack space required +by the task itself. The define + + XT_STACK_EXTRA_CLIB + +specifies the amount of extra space to be added on to the stack to allow +saving the context for the C library as well as the coprocessors if any. +E.g. if your task requires 2000 bytes of stack space, you must allocate +(2000 + XT_STACK_EXTRA_CLIB) bytes for the stack. + + +IMPORTANT NOTE +-------------- + +The header file FreeRTOS.h, which is a part of the core FreeRTOS sources, +includes if thread safety for the C libraries is enabled. For +xclib, this file exists in and so is reported as missing. +To work around this, the makefiles supplied with this port will copy the +reent.h header into the build directory during the build process. If you +use a different build process, then you must make sure to copy this file +to a location that is included in the list of include paths. This can be +the build directory or the directory that contains the Xtensa port source +files. + + +Running or Debugging an Application +----------------------------------- + +To execute the example application on the simulator: + +> xt-run [--turbo] example.exe + +The option --turbo provides much faster, but non-cycle-accurate simulation +(the --turbo option is only available with Xtensa Tools version 7 or later). + + +To execute on the simulator using the Xplorer GUI based debugger: + +> xplorer --debug example.exe + + +To execute on a supported evaluation board, download example.exe per +instructions in the tools manuals. Be sure the board has been programmed +with the correct configuration and is set up to boot from RAM and debug +a downloaded program! Optionally you may connect a terminal or terminal +emulator to the serial port on the board with settings as described in +the board user manual, and see the output of printf on the terminal. + +To obtain I/O on a "raw" platform such as an unsupported board, you need +to provide low level I/O drivers (eg. inbyte() and outbyte() for character +I/O if you want to use printf etc.). You can run "raw" executables on +any Xtensa platform, including simulator and any board, but you will not +see any behavior specific to the platform (eg. display, printed output, +stopping simulation at end of program). You can, while debugging, use a +debugger mechanism called GDBIO to obtain basic I/O. To use GDBIO, link +with the gdbio LSP. Refer to Xtensa tools documentation for details. + + +Task Stack Sizes +---------------- + +The application must ensure that every task has enough space for its +stack. Each task needs enough space for its own use, its own interrupt +stack frame (defined in xtensa_context.h) and space to save coprocessor +state, if any. Several factors influence the size of the stack required, +including the compiler optimization level and the use of the C library. +Calls to standard output functions such as printf() can use up a lot of +stack space. The tool xt-stack-usage is helpful in determining safe stack +sizes for your application. + +Some macros are provided in xtensa_config.h to help determine the stack +size for tasks that do and do not use the C library. Use these as the +basis for each task's stack size. They are minimum requirements taking +into account your configuration and use of the C library. In particular, +the define + + XT_STACK_MIN_SIZE + +defines the minimum stack size for any task. Be very careful if you try +to use a stack size smaller than this minimum. Stack overruns can cause +all kinds of hard-to-debug errors. It is recommended that you enable the +FreeRTOS stack checking features during development. + +WARNING: The newlib printf() function uses a lot of stack space. Be very +careful in using it. Optionally you can use the 'libxtutil' library for +output - it implements a subset of printf() that has smaller code size +and uses far less stack space. More information about this library is in +the Xtensa Tools documentation. + + +Interrupt Stack +--------------- + +Beginning with port version 1.2, the port uses a separate interrupt stack +for handling interrupts. Thus, it is no longer necessary for each task to +reserve space on its stack to handle interrupts. The size of the interrupt +stack is controlled by the parameter "configISR_STACK_SIZE" defined in +FreeRTOSConfig.h. Define this carefully to match your system requirements. + + +Assembler / Compiler Switches +----------------------------- + +The following are compiler switches are used by the provided +Makefile in building the FreeRTOS library and example application. +These can be modified by editing the Makefile or by overriding the +CFLAGS variable in the make command line, for example: + +> xt-make CFLAGS="-O2 -DXT_USE_THREAD_SAFE_CLIB" + + -g Specifies debug information. + -c Specifies object code generation. + -On Sets compiler optimization level n (default -O0). + -mlongcalls Allows assembler and linker to convert call + instructions to longer indirect call sequences + when target is out of range. + -x assembler-with-cpp Passes .s and .S files through C preprocessor. + -Dmacro Define a preprocessor macro with no value. + -Dmacro=value Define a preprocessor macro with a value. + +See the compiler / linker documentation for a full list of switches and +their use. + +Many definitions can be provided at compile-time via the -D option +without editing the source code. Here are some of the more useful ones: + + XT_USE_THREAD_SAFE_CLIB Enable support for the reentrancy to provide + thread-safety for the newlib and xclib libraries + supplied with Xtensa Tools. Default ON. + + Note, the follwing defines are unique to the Xtensa port so have names + beginning with "XT_". + + XT_SIMULATOR Set this if building to run on the simulator. + Takes advantage of certain simulator control + and reporting facilities, and adjusts timing + of periodic tick to provide a more acceptable + performance in simulation (see XT_CLOCK_FREQ). + Set by default unless PLATFORM is overridden. + + XT_BOARD Set this if building for a supported board. + Be sure to specify the correct LSP for the + board. See the example makefile for usage. + + XT_CLOCK_FREQ=freq Specifies the target processor's clock + frequency in Hz. Used primarily to set the + timer that generates the periodic interrupt. + Defaults are provided and may be edited in + xtensa_timer.h (see comments there also). + Default for simulator provides more acceptable + performance, but cannot provide real-time + performance due to variation in simulation + speed per host platform and insufficient + cycles between interrupts to process them. + Supported board platforms by default leave + this undefined and compute the clock frequency + at initialization unless this is explicitly + defined. + + XT_TICK_PER_SEC=n Specifies the frequency of the periodic tick. + + XT_TIMER_INDEX=n Specifies which timer to use for periodic tick. + Set this if your Xtensa processor configuration + provides more than one suitable timer and you + want to override the default. See xtensa_timer.h . + + XT_INTEXC_HOOKS Enables hooks in interrupt vector handlers + to support dynamic installation of exception + and interrupt handlers. Disabled by default. + + XT_USE_OVLY Enable code overlay support. It uses a mutex, + hence configUSE_MUTEX must be enabled. This + option is currently unsupported. + + XT_USE_SWPRI Enable software prioritization of interrupts. + Enabling this will prioritize interrupts with + higher bit numbers over those with lower bit + numbers at the same level. This works only for + low and medium priority interrupts that can be + dispatched to C handlers. + + +Register Usage and Stack Frames +------------------------------- + +The Xtensa architecture specifies two ABIs that determine how the general +purpose registers a0-a15 are used: the standard windowed ABI use with +the Xtensa windowed register file architecture, and the optional and +more conventional Call0 ABI (required for Xtensa configurations without +a windowed register file). + +Xtensa processors may have other special registers (including co-processor +registers and other TIE "states") that are independent of this choice +of ABI. See Xtensa documentation for more details. + +In the windowed ABI the registers of the current window are used as follows: + a0 = return address + a1 = stack pointer (alias sp) + a2 = first argument and result of call (in simple cases) + a3-7 = second through sixth arguments of call (in simple cases). + Note that complex or large arguments are passed on the + stack. Details are in the Xtensa Tools manuals. + a8-a15 = available for use as temporaries. +There are no callee-save registers. The windowed hardware automatically +saves registers a0-a3 on a call4, a0-a8 on a call8, a0-a12 on a call12, +by rotating the register window. Hardware triggers window overflow and +underflow exceptions as necessary when registers outside the current +window need to be spilled to preallocated space in the stack frame, or +restored. Complete details are in the Xtensa manuals. The entire windowed +register file is saved and restored on interrupt or task context switch. + +The Call0 ABI does not make use of register windows, relying instead +on a fixed set of 16 registers without window rotation. +The Call0 ABI is more conventional and uses registers as follows: + a0 = return address + a1 = stack pointer (alias sp) + a2 = first argument and result of call (in simple cases) + a3-7 = second through sixth arguments of call (in simple cases). + Note that complex or large arguments are passed on the + stack. Details are in the Xtensa Tools manuals. + a8-a11 = scratch. + a12-a15 = callee-save (a function must preserve these for its caller). +On a FreeRTOS API call, callee-save registers are saved only when a task +context switch occurs, and other registers are not saved at all (the caller +does not expect them to be preserved). On an interrupt, callee-saved +registers might only be saved and restored when a task context-switch +occurs, but all other registers are always saved and restored. + +An Xtensa processor has other special registers independent of the ABI, +depending on the configuration (including co-processor registers and other +TIE state) that are part of the task context. FreeRTOS preserves all such +registers over an unsolicited context-switch triggered by an interrupt. +However it does NOT preserve these over a solicited context-switch during +a FreeRTOS API call. This bears some explanation. These special registers +are either ignored by the compiler or treated as caller-saved, meaning +that if kept "live" over a function call (ie. need to be preserved) +they must be saved and restored by the caller. Since solicited entry to +FreeRTOS is always made by a function call, FreeRTOS assumes the caller +has saved any of these registers that are "live". FreeRTOS avoids a lot +of overhead by not having to save and restore every special register +(there can be many) on every solicited context switch. + +As a consequence, the application developer should NOT assume that special +registers are preserved over a FreeRTOS API call such as vTaskDelay(). +If multiple tasks use a register, the caller must save and restore it. + +The saved context stack frames for context switches that occur as +a result of interrupt handling (interrupt frame) or from task-level +API calls (solicited frame) are described in human readable form in +xtensa_context.h . All suspended tasks have one of these two types +of stack frames. The top of the suspended task's stack is pointed to +by pxCurrentTCB->pxTopOfStack. A special location common to both stack +frames differentiates solicited and interrupt stack frames. + + +Improving Performance, Footprint, or Ease of Debugging +------------------------------------------------------ + +By default FreeRTOS for Xtensa is built with debug (-g) and without +compiler optimizations (-O0). This makes debugging easier. Of course, +-O0 costs performance and usually also increases stack usage. To make +FreeRTOS run faster you can change the Makefile to enable the desired +optimizations or set a predefined optimization level (-O) . + +Maximum performance is achieved with -O3 -ipa, but that might increase +the footprint substantially. A good compromise is -O2. See the compiler +manual for details. + +Minimal footprint is achieved by optimizing for space with -Os, at the +cost of some performance. See the compiler manual for details. + +The Xtensa architecture port-specific assembly files are coded with no +file-scope labels inside functions (all labels inside functions begin with +".L"). This allows a profiler to accurately associate an address with a +function, and also allows the debugger's stack trace to show the correct +function wherever the program counter is within that function. However +there are some tradeoffs in debugging. Local (".L") labels are not +visible to the debugger, so the following limitations may be observed +during debugging: +- You cannot set a breakpoint on a local label inside a function. +- Disassembly will show the entire function, but will get out of sync and + show incorrect opcodes if it crosses any padding before an aligned local + branch target (".L" label, not ".Ln"). Restart disassembly specifying an + address range explicitly between points where there is padding. +Since FreeRTOS is provided in source form, it is not difficult to remove +the ".L" and ".Ln" prefixes from local labels if you want them visible. +They can also be made visible by passing the '-L' option to the assembler +and linker (see the assembler and linker manuals for details). + + +Interrupt and Exception Handling +-------------------------------- + +FreeRTOS provides a complete set of efficient exception and first-level +interrupt handlers installed at the appropriate exception and interrupt +vector locations. The Xtensa architecture supports several different +classes of exceptions and interrupts. Being a configurable architecture, +many of these are optional, and the vector locations are determined by +your processor configuration. (Note that Diamond cores are pre-configured +with specific vector locations.) The handlers provided use conditional +compilation to adapt to your processor configuration and include only +the code that is needed. + +Xtensa vector locations may reside almost anywhere, including in ROM. +The amount of code space available at each of these locations is +often very small (e.g. due to following vectors). A small stub of +code installed at the vector jumps to the corresponding handler, +usually in RAM. The exception and interrupt handlers are defined in +xtensa_vectors.S. They are not specific to FreeRTOS, but call into +FreeRTOS where appropriate via macros defined in xtensa_rtos.h . + +The handlers provided for low and medium priority interrupts are just +dispatchers that save relevant state and call user-definable handlers. +See the files xtensa_vectors.S and xtensa_api.h for more details of how +to create and install application-specific user interrupt handlers. +Similarly, user-defined handlers can be installed for exceptions (other +than a few which are always handled by the OS). + +The high priority interrupt handlers provided may be considered templates +into which the application adds code to service specific interrupts. +The places where application handlers should be inserted are tagged with +the comment "USER_EDIT" in xtensa_vectors.S. + +This FreeRTOS port supports strict priority-based nesting of interrupts. +An interrupt may only nest on top of one of strictly lower priority. +Equal priority interrupts concurrently pending are handled in an +application-defined sequence before any lower priority interrupts +are handled. During interrupt and exception handling, the processor's +interrupt level (PS.INTLEVEL) is used to control the interrupt priority +level that can be accepted; interrupt sources are not controlled +individually by FreeRTOS (the application is free to access the INTENABLE +register directly to enable/disable individual interrupts, eg. using +Xtensa HAL services). This approach provides the most deterministic +bounds on interrupt latency (for a given priority) and stack depth. + +Software prioritization of interrupts at the same priority is controlled +by the definition of XT_USE_SWPRI. See above for a description of this +parameter. + +The following subsections describe the handling of each class of exception +and interrupt in more detail. Many have nothing to do with FreeRTOS but +are mentioned because there is code to handle them in xtensa_vectors.S. + +User Exception and Interrupt Handler (Low/Medium Priority): + + All Xtensa 'general exceptions' come to the user, kernel, or double + exception vector. The exception type is identified by the EXCCAUSE + special register (level 1 interrupts are one particular cause of a + general exception). This port sets up PS to direct all such exceptions + to the user vector. Exceptions taken at the other two vectors usually + indicate a kernel or application bug. + + Level 1 interrupts are identified at the beginning of the handler + and are dispatched to a dedicated handler. Then, syscall and alloca + exceptions are identified and dispatched to special handlers described + below. After this, coprocessor exceptions are identified and dispatched + to the coprocessor handler. + + Any remaining exceptions are processed as follows: + + Having allocated the exception stack frame, the user exception handler + saves the current task state and sets up a C environment and enables + the high-priority class of interrupts (which do not interact with + FreeRTOS), then reads EXCCAUSE and uses the cause (number) to index + into a table of user-specified handlers. The correct handler is then + called. If the handler returns, the context is restored and control is + returned to the code that caused the exception. The user-defined handler + may alter the saved context, or any other system state, that allows the + faulting instruction to be retried. + + If the cause is a level 1 (low-priority) or medium-priority interrupt, + the handler enables all interrupts above that priority level after + saving the task context. It then sets up the environment for C code + and then calls the handler (found in the handler table) for the + interrupt number. If the user has not specified a handler, then the + default handler will be called, which will terminate the program. + + If the interrupt is for the system timer, it calls a special interrupt + handler for the system timer tick, which calls _frxt_timer_int then + clears its bit from the mask. This interrupt cannot be hooked by the + user-defined handler. + + Finally, the handler calls _frxt_int_exit to allow FreeRTOS to perform + any scheduling necessary and return either to the interrupted task + or another. + + If software prioritization is enabled, the handler will re-enable all + interrupts at the same level that are numerically higher than the current + one, before calling the user handler. This allows a higher priority + interrupt to pre-empt the lower priority handler. + +Medium Priority Interrupt Handlers: + + Medium priority interrupts are those at levels 2 up to XCHAL_EXCM_LEVEL, + a configuration-specific maximum interrupt level affected by the global + 'exception mode' bit in the processor status word (PS.EXCM). + Interrupt levels above XCHAL_EXCM_LEVEL are of the high-priority class. + The Xtensa hardware documentation considers medium priority interrupts + to be a special case of high-priority interrupts, but from a software + perspective they are very different. + + Dispatch of medium-priority interrupts is discussed in the section + above. + +High Priority Interrupt Handlers: + + High priority interrupts are those strictly above XCHAL_EXCM_LEVEL, + a configuration-specific maximum interrupt level affected by the + global 'exception mode' bit in the processor status word (PS.EXCM). + High priority handlers may not directly interact with FreeRTOS at all, + and are described here only for the sake of completeness. They must + be coded in assembler (may not be coded in C) and are intended to be + used for handling extremely high frequency hardware events that need + to be handled in only a few cycles. A high priority interrupt handler + may trigger a software interrupt at a medium or low priority level to + occasionally signal FreeRTOS. Please see Xtensa documentation. + + There is a separate vector and a few special registers for each high + priority interrupt, providing for fast dispatch and efficient nesting + on top of lower priority interrupts. Handlers are templates included + only for the vectors that exist in your Xtensa processor configuration. + These templates are written for only one interrupt per high priority + level to minimize latency servicing very fast time-critical interrupts. + The vector code jumps to the corresponding first-level interrupt handler, + which then executes application-provided assembler code before returning + quickly to the interrupted task or lower priority handler. + +Kernel Exception Handler: + + Kernel mode is not used in this port of FreeRTOS, and therefore kernel + exceptions should not happen. A stub is provided for the vector that + triggers the debugger (if connected) or calls _xt_panic to freeze the + processor should a kernel exception occur. + +Alloca Exception Handler: + + Alloca exceptions are generated by the 'movsp' instruction, which + is used only in the windowed ABI. Its purpose is to allocate some + space on top of the stack. Because the window hardware may have + spilled some registers to the 16 byte "base save" area below the + stack pointer, it is necessary to protect those values. The alloca + handler accomplishes this quickly without setting up an interrupt + frame or entering FreeRTOS, by emulating a register underflow and + re-executing 'movsp'. + +Syscall Exception Handler: + + Syscall exceptions are generated by a 'syscall' instruction. + The windowed ABI specifies that executing this instruction with + a value of zero in register a2 must spill any unsaved registers + in the windowed register file to their pre-determined locations + on the caller's stack. The handler does exactly that, and skips + over the 'syscall' instruction before returning to the caller. + If a2 is non-zero, the handler returns a2 == -1 to the caller. + +Co-Processor Exception Handler: + + A co-processor exception is generated when a task accesses a + co-processor that it does not "own". Ownership represents which + task's state is currently in the co-processor. Co-processors are + context-switched "lazily" (on demand) only when a non-owning task + uses a co-processor instruction, otherwise a task retains ownership + even when it is preempted from the main processor. The co-processor + exception handler performs the context-switch and manages ownership. + + Co-processors may not be used by any code outside the context of a + task. A co-processor exception triggered by code that is not part + of a running task is a fatal error and FreeRTOS for Xtensa will panic. + This restriction is intended to reduce the overhead of saving and + restoring co-processor state (which can be quite large) and in + particular remove that overhead from interrupt handlers. + +Debug Exception Handler: + + A debug exception is caused as a result of running code, such as by + a 'break' instruction or hardware breakpoints and watchpoints, or + as a result of an external debug interrupt, such as from an OCD based + debugger or multiprocessor debug events ("breakin/breakout"). If the + processor is running in OCD mode under control of an OCD-based debugger, + the trigger event immediately halts the processor and gives control to + the OCD debugger. Otherwise control is transferred to the debug vector. + The debug vector handler calls the simulator if running on the ISS, + which then takes control and interacts with any attached debugger. + If running on hardware and not in OCD mode, debug exceptions are not + expected, so the debug handler calls _xt_panic to freeze the processor. + +Double Exception Handler: + + A double exception is a general exception that happens while the + processor is in exception mode (PS.EXCM set), and thus indicates a + bug in kernel code. The double exception vector handler triggers + the debugger (if connected) or calls _xt_panic to freeze the + processor. + +Window Overflow and Underflow Exception Handlers: + + Window overflow and underflow handlers are required for use of the + windowed ABI. Each has its own dedicated vector and highly optimized + code that is independent of OS. See Xtensa documentation for details. + +Hooks for Dynamic Installation of Handlers: + + Optional hooks are provided in the user exception and low level + interrupt handler and all medium and high priority interrupt handlers, + to dynamically install a handler function (which may be coded in C, + unless in a high-priority interrupt handler). These hooks are enabled + and used by automatic regression tests, they are not part of a normal + FreeRTOS build. However an application is free to take advantage of + them. The interrupt/exception hooks are described in xtensa_rtos.h . + + It is recommended that the application not make use of these hooks, but + rather use xt_set_interrupt_handler() and xt_set_exception_handler() + to install application-specific handlers. This method is more convenient + and allows arguments to be passed to the handlers. Software prioritization + of interrupts works only with this method.

Co-processors are context-switched + lazily (on demand) only when a new thread uses a co-processor instruction, + otherwise a thread retains ownership of the co-processor even when it loses + control of the processor. An Xtensa co-processor exception is triggered when + any co-processor instruction is executed by a thread that is not the owner, + and the context switch of that co-processor is then peformed by the handler. + Ownership represents which thread's state is currently in the co-processor. + + Co-processors may not be used by interrupt or exception handlers. If an + co-processor instruction is executed by an interrupt or exception handler, + the co-processor exception handler will trigger a kernel panic and freeze. + This restriction is introduced to reduce the overhead of saving and restoring + co-processor state (which can be quite large) and in particular remove that + overhead from interrupt handlers. + + The co-processor state save area may be in any convenient per-thread location + such as in the thread control block or above the thread stack area. It need + not be in the interrupt stack frame since interrupts don't use co-processors. + + Along with the save area for each co-processor, two bitmasks with flags per + co-processor (laid out as in the CPENABLE reg) help manage context-switching + co-processors as efficiently as possible: + + XT_CPENABLE + The contents of a non-running thread's CPENABLE register. + It represents the co-processors owned (and whose state is still needed) + by the thread. When a thread is preempted, its CPENABLE is saved here. + When a thread solicits a context-swtich, its CPENABLE is cleared - the + compiler has saved the (caller-saved) co-proc state if it needs to. + When a non-running thread loses ownership of a CP, its bit is cleared. + When a thread runs, it's XT_CPENABLE is loaded into the CPENABLE reg. + Avoids co-processor exceptions when no change of ownership is needed. + + XT_CPSTORED + A bitmask with the same layout as CPENABLE, a bit per co-processor. + Indicates whether the state of each co-processor is saved in the state + save area.

This consists of an array of function pointers indexed +by interrupt priority, with index 0 being the user exception handler hook. +Each entry in the array is initially 0, and may be replaced by a function +pointer of type XT_INTEXC_HOOK. A handler may be uninstalled by installing 0. + +The handler for low and medium priority obeys ABI conventions so may be coded +in C. 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).

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 includes non-maskable (NMI). 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).
