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

c41c02872f freertos: prvCheckTasksWaitingTermination bugfix
Bugfix to prevent a self deleting no affinity task's memory from being freed by the
idle task of the other core before the self deleting no affinity task is able to context
switch out.  prvCheckTasksWaitingTermination now checks if the task is still on
pxCurrentTCB before freeing task memory.

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.

38afa32cfb freertos/fix SMP bug with Idle task clean up
This commit backports vTaskDelete() behavior from FreeRTOS v9.0.0  which
allows for the immediate freeing of task memory if the task being deleted
is not currently running and not pinned to the other core. This commit also
fixes a bug in prvCheckTasksWaitingTermination which prevented the
Idle Task from cleaning up all tasks awaiting deletion. Each iteration of the Idle
Task should traverse the xTasksWaitingTermination list and clean up all tasks
not pinned to the other core. The previous implementation would cause
prvCheckTasksWaitingTermination to return when encountering a task
pinned to the other core whilst traversing the xTasksWaitingTermination list.

The test case for vTaskDelete() has been updated to test for the bugfix and
backported deletion behavior.

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

62f44e45df ringbuf: Bugfixes for managing arbitrary sizes of ring buffer
It was observed that if the ring buffer size provided by application
is not a multiple of 4, some checks were failing (as read_ptr and write_ptr
could shoot beyond the ring buffer boundary), thereby causing asserts.
Simply wrapping around the pointers for such cases fixes the issue.

Moreover, because of the logic for maintaining 4-byte boundary,
it was also possible that a wrap-around occurred for some data,
even when the actual size remaining was sufficient for it.
Eg. Buffer available: 34, data size: 34, 4-byte aligned size: 36
Since the logic compares against 36, it writes 34 bytes and does a
wraparound. But since all 34 bytes are already written, there is
nothing to write after wrapping. It is better to just re-set the
write pointer to the dtart of ring buffer in such cases.

Tested send/receive for various arbitrary sizes of data and for
arbitrary sizes of ring buffer.

Alternative Solutions:
1) Allow only sizes which are multiples of 4, and return error otherwise.
Appropriate code and documentation change would be required
2) Allow arbitrary sizes, but internally add upto 3 bytes to make
the total size a multiple of 4

8b56345e44 unit tests: fix queue registry test
In the queue registry test, start_sem is given twice to let both tasks
start the test. Each task takes start_sem, does some work, gives done_sem,
and goes on to wait for start_sem again.
It may happen that one task can grab start_sem, add queues to the
registry, give done_sem, then grab start_sem again, delete the queues
from the registry, and give done_sem again. At this point, main test
task takes done_sem twice and proceeds to verify that queues have been
added to the registry. But in fact, the first task has already deleted
its queues from the registry, and the second one might not have added
the queues yet. This causes test to fail.

This changes the test to use separate start semaphores for each task,
to avoid the race condition.

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.

9903ea1c11 Add --warn-undefined-variables to MAKEFLAGS
Fix warnings where undefined vars are used.

Make Kconfig emit "FOO=" for unset bool options
To ensure make variables are always defined, even if empty.

When writing auto.conf, include symbols disabled by dependency to make sure all make variables are always defined.

Fixes espressif/esp-idf#137

db58a2732b freertos: vPortCPUReleaseMutex() no longer returns a value
Unlocking a never-locked mutex is an assertion failure in debug mode.

In release mode, this further improves performance:
No-Contention ->  153 cycles
Recursion No-Contention -> 138 cycles
Contention -> 378 cycles

99a4b6b2db freertos: introduce CONFIG_FREERTOS_INTERRUPT_BACKTRACE
The code in xtensa_vectors.S did not handle XT_DEBUG_BACKTRACE
consistently: #if was used in one case, and #ifdef in another. This makes
the checks consistent, and also introduces a Kconfig option to enable
backtrace.

eb1b4f971b freertos: make sure xPortGetCoreID is placed into IRAM
In some cases, xPortGetCoreID was not inlined, and ended up in flash.
Since this function is used in many situations when cache is disabled,
that caused exceptions. Adding IRAM attribute to fix that.

ba8cd58b08 kconfig: Remove Wi-Fi on/off as a menuconfig option
This is no longer required since the functions automatically get
pulled in based on the usage. A quick summary of footprint
comparisions before and after these set of patches is shown below:

Hello-World: (simplified for readability)
 old Total image size:~ 104902 bytes (.bin may be padded larger)
 old Total image size:~ 105254 bytes (.bin may be padded larger)
 Per-archive contributions to ELF file:
             Archive File DRAM .data & .bss   IRAM Flash code & rodata   Total

 new              libesp32.a       1973    185   4473       3939     2267   12837

 new             libnvs_flash.a          0     92      0        274        8     374

For some reason, nvs_flash.a (~400bytes) gets pulled in (particularly
the nvs_flash_init() function).

Power-Save: (simplified for readability)
 old Total image size:~ 421347 bytes (.bin may be padded larger)
 old Total image size:~ 421235 bytes (.bin may be padded larger)

 old      libtcpip_adapter.a          0     81      0       1947      115       2143

The size actually shrinks a bit, since the AP interface function
doesn't get pulled in.

d664e32394 build system: Use component.mk for all components, refactor bootloader build
For config-only components, component.mk should now contain "COMPONENT_CONFIG_ONLY := 1"

Also refactored some of the generation of linker paths, library list. This required cleaning up the way the bootloader
project works, it's now mostly independent from the parent.

8d43859b6a esp32: SEGGER SystemView Tracing Support
Implements support for system level traces compatible with SEGGER
SystemView tool on top of ESP32 application tracing module.
That kind of traces can help to analyse program's behaviour.
SystemView can show timeline of tasks/ISRs execution, context switches,
statistics related to the CPUs' load distribution etc.

Also this commit adds useful feature to ESP32 application tracing module:
 - Trace data buffering is implemented to handle temporary peaks of events load

[871ec26f] Freertos:Bugfix uxTaskGetSystemState

Bug (github #12142) with uxTaskGetSystemState where
if called immediately after creating a bunch of tasks,
those tasks would be added twice into the TaskStatusArray.
Bug caused due to use old implementation using vTaskSuspendAll
which did not stop newly created task on other core from accessing the
read/waiting task lists whilst the list were being read by
uxTaskGetSystemState. Fixed bug by replacing vTaskSuspendAll
with taskENTER_CRITICAL and added test case for the bugfix
