f8c42369f1 freertos: Adds C11 TLS support 2018-02-07 18:46:57 +03:00
Jeroen Domburg
70ab924dbb Especially when internal memory fills up, some FreeRTOS structures (queues etc) get allocated in psram. These structures also contain a spinlock, which needs an atomic-compare-swap operation to work. The psram hardware, however, does not support this operation. As a workaround, this patch detects these spinlocks and will, instead of S32C1I, use equivalent C-code to simulate the behaviour, with an (internal) mux for atomicity. 2018-02-02 17:11:06 +08:00

91968ef464 freertos/ringbuf: Added an API xRingbufferCreateNoSplit()
This is a wrapper API for creating a Ring Buffer, which ensures that
the ringbuffer can hold the given number of items, each item being of the
same given length.

3c199b0de6 freertos/ringbuf: Add an API xRingbufferIsNextItemWrapped()
Useful to check if the next item to receive is wrapped or not.
This is valid only if the ring buffer is initialised with type
RINGBUF_TYPE_ALLOWSPLIT.

cd5fb054c7 freertos/ringbuf: Add an API xRingbufferGetCurFreeSize() to fetch current free size available
The earlier available API (xRingbufferGetMaxItemSize())just gives
a static max entry value possible for given ring buffer.
There was a feature request for an API which could provide
a real time available buffer size. See below:

cda22d9aaf docs: add FreeRTOS API docs
- Use `code` tags instead of a mix of `<pre></pre>` and
  `@verbatim .. @endverbatim`
- Remove manually added function prototypes from comment blocks
- Remove of grouping (`\defgroup`) — some extra work is needed
  to make groups compatible with the way we auto-generate API
  reference from Doxygen XML files. It's pretty easy to add the
  grouping directives back if/when we implement support for
  Doxygen groups in the later stages of documentation build
  process.
- Hide private APIs under `@cond .. @endcond`
- Convert some comments into Doxygen-compatible ones
- Fix various documentation issues: missing documentation for
  some parameters, mismatch between parameter names in comment
  block and in function prototype.
- Add doxygen comments for functions which didn't have them
  (thread local storage).
- Add [out] param tags where necessary
- Redefine `xTaskCreate` and `xTaskCreateStatic` as inline
  functions instead of macros.

7dd9c4f57f ringbuf: Fixes to header files for better understanding
1. Usage of this module required applications to include additional
files. What files to include is not very intuitive. Instead, it is
better for the header file itself to include other files as required.
2. Even though it may seem logical, it is better to explicitly mention
that an item needs to be "Returned" after a Receive

d1853dbbc0 FreeRTOS/make Queue Registry and Run Time Stats configurable
This commit makes the configQUEUE_REGISTRY_SIZE and
configGENERATE_RUN_TIME_STATS configurable in menuconfig.

- configQUEUE_REGISTRY_SIZE can now be set in menuconfig.
- The functions vQueueAddToRegistry() and vQueueUnregisterQueue() were made
  SMP compatbile
- pcQueueGetName() was backported from FreeRTOS v9.0.0
- Added test case for Queue Registry functions

- configGENERATE_RUN_TIME_STATS can now be enabled in menuconfig. CCOUNT or
  esp_timer can be selected as the FreeRTOS run time clock in menuconfig as
  well, although CCOUNT will overflow quickly.
- Run time stats collection (in vTaskSwitchContext) and generation (in
  uxTaskGetSystemState) have been made SMP compatible. Therefore
  vTaskGetRunTimeStats() now displays the run time usage of each task as a
  percentage of total runtime of both CPUs

9d63e1da4a New Task Watchdog API (Revert of Revert)
This commit reverts the revert on the new task watchdog API. It also
fixes the following bug which caused the reversion.

- sdkconfig TASK_WDT_TIMEOUT_S has been reverted from the unit of ms back to the
unit of seconds. Fixes bug where projects using the new API without rebuilding sdkconfig
would cause the old default value of 5 to be interpreted in ms.

This commit also adds the following features to the task watchdog

- Updated idle hook registration to be compatible with dual core hooks

- Updated dual core hooks to support deregistration for cpu

- Legacy mode has been removed and esp_task_wdt_feed() is now replaced by
  esp_task_wdt_reset().  esp_task_wdt_feed() is deprecated

- Idle hooks to reset are now registered/deregistered when the idle tasks are
  added/deleted from the Task Watchdog instead of at Task Watchdog init/deinit

- Updated example

616baa239d esp32: New Task Watchdog API
Legacy API of task watchdog used the same function esp_task_wdt_feed() to add
and feed a task. This caused issues of implicitly adding a task to the wdt list
if the function was used in shared code.

The new API introduces init, adding, feeding, deleting, deinit functions. Tasks
must now be explicitly added to the task watchdog using their handles. Deletion
must also be explicit using task handles. This resolves the issue of implicit
task additions to the task watchdog due to shared code calling
esp_task_wdt_feed().

Task watchdog is now fully configurable at runtime by calling the init and
deinit functions.

Also added functions to get the handles of idle tasks of the other core. This
helps when adding idle tasks to the watchdog at run time.

Configuring the task watchdog using menu config is still available, however
menu config will only result in calling the init and add functions for idle
tasks shortly after the scheduler starts.

Menu config also allows for using legacy behavior, however the legacy behavior
willcall the new API functions but with slight variations to make them legacy
compatible.

Documentation and example have also been updated

gcov_rtio.c headers updated to prevent error of freertos header files being
included in the wrong order.

Resolves issue TW#13265

79646f41b5 Fixes for stdlib.h inclusion
Refs:
http://esp32.com/viewtopic.php?f=13&t=550
http://esp32.com/viewtopic.php?f=13&t=551

rmt.c should include stdlib.h for malloc, esp_bignum,c &
https_request_main.c for abort().

FreeRTOSConfig.h is only including stdlib if
CONFIG_FREERTOS_ASSERT_ON_UNTESTED_FUNCTION is set. However, it is
included for abort() so needs to be included whenever
CONFIG_FREERTOS_ASSERT_FAIL_ABORT is set.

This change includes unconditionally in FreeRTOSConfig.h. This is to
avoid this kind of bug where compiler errors are dependent on config. I
suggest we don't change this to be more selective until we have 'make
randomconfig' style tests in CI.

180f4d0929 FreeRTOS: Use C11 _Static_assert to verify static "dummy" structs at compile time
Includes a tweak to make Static_task_t equal size to TCB_t when using
MPU_WRAPPERS . Matches tskSTATIC_AND_DYNAMIC_ALLOCATION_POSSIBLE macro
in tasks.c. This isn't actually a bug (if static task allocation is off,
there is no use for Static_task_t), but it allows us to make consistent
compile-time checks that Static_task_t == TCB_t.

2a73783bc6 StaticQueue_t needs to have the same size as xQUEUE.
Without this change, building FreeRTOS with static allocation enabled succeeds, but trying to create a queue from a static buffer causes an assert because the size of static and dynamic queues differ.

f5cebd2666 Merge branch 'feature/per_cpu_interrupt_handlers' into 'master'
Per-CPU interrupt handlers and args

Up to now, the interrupt handlers and args were shared between CPUs, that is, if you set an interrupt handler on CPU0, CPU1 would invoke the same interrupt handler on that interrupt. This code gives every CPU its own space for interrupt handlers.

ffeffcd315 Merge branch 'feature/crosscore_int' into 'master'
Add cross-core int to accelerate task being awoken from another CPU.

This adds a per-CPU interrupt that can be used to poke the CPU to go do something. In this case all that is implemented is a request to yield the current task, used in case a CPU unblocks a task that runs on another CPU. This gets rid of the limitation that inter-CPU communication using queues, muxes etc can take up to a FreeRTOS tick to happen.

Specs!
Sending an in in a queue of length 1 (essentially a semaphore) as quickly as possible (just a small delay in the sender, to make sure the receiver task gets swapped out) for 10 seconds. Number indicates the amount of ints transferred

Old code:

CPU0->CPU0: 42986

CPU0->CPU1,: 2999

New code:

CPU0->CPU0: 42868

CPU0->CPU1: 62073

38c6256db9 Merge branch 'feature/wdts' into 'master'
Feature/wdts

This adds two watchdogs to  esp-idf:

- An interrupt watchdog. Kicks in if the FreeRTOS timer interupt on either the PRO_CPU or (when configured) the APP CPU isn't called for a configurable time. Panics, displaying which CPU caused the problem and the registers that may lead to the offending code.
- A task watchdog. A task has to feed it every once in a while. If not, it will print the name of the offending tasks, as well as the tasks currently running on both CPUs, and optionally panic.

Also adds a panic reason to the panic call, as well as fixes the panic code a bit.

0383bc8599 Merge branch 'workaround/pin_noaffinity_task_to_core_when_fpu_used' into 'master'
Workaround: Automatically pin no-cpu-affinity task to a core when FPU is used

FPU status at the moment does not migrate cleanly between cores, so tasks without affinity that happen to migrate across FPUs will run into problems. As a workaround, this modification will automatically pin the task to the current CPU when FPU activity is detected. If anything, it's better than getting all kinds of weird and wonderful FPU corruption issues...

01d17dd5f9 Backport the static allocation feature from FreeRTOS V9.0.0
This feature allows to use static buffers (or from a pool of memory which is not
controlled by FreeRTOS).
In order to reduce the impact of the changes, the static feature has only been added
to the queus (and in consequence to the semaphores and the mutexes) and the tasks.
The Timer task is always dynamically allocated and also the idle task(s), which in the
case of the ESP-IDF is ok, since we always need to have dynamic allocation enabled.
