Vanilla FreeRTOS expects applications to use one of the heap implementations
provided by FreeRTOS (i.e., heap_x.c), where functions such as pvPortMalloc()
and vPortFree() are defined in the heap implementation.
However, ESP-IDF already provides its own heap implementation
(i.e., esp_heap_caps.h). Thus, the pvPortMallc()/vPortFree() functions were
previously overriden by macro to call esp_heap functions directly.
This commit refactors the FreeRTOS port's heap as such:
- Added a heap_idf.c that implements all of the heap related functions required
by FreeRTOS source
- All dynamic memory allocated by FreeRTOS is from internal memory. Thus, the
FreeRTOS heap is the internal memory subset of the ESP-IDF heap.
- Removed some old macros to reduce diff from upstream source code.
The stream buffer send-receive test preivously contained the following bugs:
- "sender" task would send 101 bytes instead of 100
- The main task would return before "sender" task sends its 101st item. Thus
the sender task would cause memory corruption when accessing "tc" structure
allocated on the main task's stack
This commit fixes and simplifies the stream buffer test.
This commit updates the FreeRTOS port FPU unit tests so that they run for
multiple iterations, thus checking that a task's FPU context is properly
cleaned up on deletion.
This commit fixes flakey task delay tests when running on IDF FreeRTOS. IN IDF
FreeRTOS, core 1's tick interrupts could be up to (< 1 tick) out of phase from
core 0's tick interrupt, thus the measured delay time on core 1 could last 1
tick longer. This commit makes the test detla 2 ticks for IDF FreeRTOS.
This commit fixes/ignores flakey freertos unit tests after migrating them to
the test app:
- Added vTaskDelay() before teardown to prevent memory leaks
- Adjusted the "main" task's priority so that scheudling tasks would work
- pytest now only runs tests that are not ignored
- Reset tests are temporarily ignored. Will be enabled to dedicate reset tests.
- Some flakey tests are fixed by adjusting delays and stack sizes.
This commit adds the sdkconfig files for the FreeRTOS test app. These
configurations were dervied from the various legacy unit test app's
config files that included the FreeRTOS component.
This commit tries to keep a 1 to 1 config parity with the legacy test app.
Meaning, if FreeRTOS test were run on a particular target with a particular
config, that config will be represented in one of the test app's
sdkconfig.ci.XXX files.
However, the following configurations were removed for FreeRTOS tests:
- The "freertos_flash" option was removed due to redudancy (already tested in
freertos_options)
Some tests were placed in the incorrect test groups (i.e., kernel, port,
performance etc). This commit fixes those placements.
The following redundant tests were also removed:
- "test_panic.c" as behavior is already covered in esp_system tests
