Darian Leung 037c079e9a esp32: Refactor backtrace and add esp_backtrace_print()
This commit refactors backtracing within the panic handler so that a common
function esp_backtrace_get_next_frame() is used iteratively to traverse a
callstack.

A esp_backtrace_print() function has also be added that allows the printing
of a backtrace at runtime. The esp_backtrace_print() function allows unity to
print the backtrace of failed test cases and jump back to the main test menu
without the need reset the chip. esp_backtrace_print() can also be used as a
debugging function by users.

- esp_stack_ptr_is_sane() moved to soc_memory_layout.h
- removed uncessary includes of "esp_debug_helpers.h"

Darian Leung 4bfa30967f freeRTOS/Re-factor ring buffers
This fixes multiple bugs with ring buffers and re-factors the code. The public
API has not changed, however the underlying implementation have various private
functions have been changed. The following behavioral changes have been made

-   Size of ring buffers for No-Split/Allow-Split buffers will not be rounded
    up to the nearest 32-bit aligned size. This was done to simplify the
    implementation

-   Item size for No-Split/Allow-Split buffers will also be rounded up to the
    nearest 32-bit aligned size.

The following bugs have been fixed

-   In copyItemToRingbufAllowSplit(), when copying an item where the aligned
    size is smaller than the remaining length, the function does not consider
    the case where the true size of the item is less than 4 bytes.

-   The copy functions will automatically wrap around the write pointers when
    the remaining length of the buffer is not large enough to fit a header, but
    does not consider if wrapping around will cause an overlap with the read
    pointer. This will make a full buffer be mistaken for an empty buffer

closes #1711
-   xRingbufferSend() can get stuck in a infinite loop when the size of the
    free memory is larger than the needed_size, but too small to fit in the ring
    buffer due to alignment and extra overhead of wrapping around.

closes #1846
-   Fixed documentation with ring buffer queue set API

-   Adding and removing from queue set does not consider the case where the
    read/write semaphores actually hold a value.

The following functions have been deprecated
    - xRingbufferIsNextItemWrapped() due to lack of thread safety
    - xRingbufferAddToQueueSetWrite() and xRingbufferRemoveFromQueueSetWrite()
    as adding the queue sets only work under receive operations.

The following functions have been added
    - xRingbufferReceiveSplit() and xRingbufferReceiveSplitFromISR() as a thread
    safe way to receive from allow-split buffers
    - vRingbufferGetInfo()

Documentation for ring buffers has also been added.

Darian Leung 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.

Darian Leung 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

Darian Leung 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

Darian Leung 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

Darian Leung ae9041ab71 esp32: Fix task watchdog timer triggering issues TW#14794
The two task watchdog timer bugs are as follows...
1) If only a single task existed on the wdt task list, and esp_task_wdt_feed()
was only called once, the watchdog triggers but fails to print task name
2) If a single task already exists on the task wdt list, and another task calls
esp_task_wdt_feed() once, the watchdog fails to trigger

Problem stemmed from the loop responsible for resetting the watchdog timer
having incorrect loop parameters. The loop failed to traverse the full length
of the task wdt list

Darian Leung 4fbeaba77f Bugfix/ added esp_adc_cal include guards 2017-09-01 12:07:37 +08:00
Darian Leung 88b05f9391 esp_adc_cal: Added ADC calibration component
Added component containg API that is able to correct raw ADC readings
into a voltage in mV. Also provided a helper function that combines
the process of getting the raw ADC1 reading then converting it to a
voltage in mV. In doing so, the adc1_get_voltage() function of the ADC
driver has been deprecated. Instead there is now adc1_get_raw to obtain
the raw ADC1 reading, and adc1_to_voltage() that gets the raw reading
and converts all in one function. Functions using the deprecated
adc1_get_voltage() have also been updated to use adc1_get_raw().

Conversion is based on ADC characteristics. The characteristics are based
on the ADC's v_ref, herefore the appropriate structure and functions have
been provided to obtain the ADC characteristics.

The existing ADC driver has also been modified by adding a function to
route the internal ADC reference voltage to a GPIO allowing users to measure
it manually.

Relevant documentation has also been updated

Darian Leung 21f02a6955 Bugfix - Panic Handler not halting when running on both cores
Bug occurs when core dump destination in menuconfig is set to flash. When
programme crashes, xt_unhandled_exception or panicHandler will both trigger
commonErrorHandler. commonErrorHandler calls esp_core_dump_to_flash which
will attempt to use DPORT functions and hang due to trying to a stall and already
stalled processor (already stalled in xt_unhandled_exception and panicHandler).
Program will eventually be rebooted when wdt expires.

Added esp_dport_access_int_deinit after calls to haltOtherCore() so that DPORT
functions don't try to halt and already halted cpu hence preventing hang.

Fixes TW#12944 https://github.com/espressif/esp-idf/issues/646

[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
