/*-----------------------------------------------------------------------------
* STACK REQUIREMENTS
*
* This section defines the minimum stack size, and the extra space required to
* be allocated for saving coprocessor state and/or C library state information
* (if thread safety is enabled for the C library). The sizes are in bytes.
*
* Stack sizes for individual tasks should be derived from these minima based on
* the maximum call depth of the task and the maximum level of interrupt nesting.
* A minimum stack size is defined by XT_STACK_MIN_SIZE. This minimum is based
* on the requirement for a task that calls nothing else but can be interrupted.
* This assumes that interrupt handlers do not call more than a few levels deep.
* If this is not true, i.e. one or more interrupt handlers make deep calls then
* the minimum must be increased.
*
* If the Xtensa processor configuration includes coprocessors, then space is
* allocated to save the coprocessor state on the stack.
*
* If thread safety is enabled for the C runtime library, (XT_USE_THREAD_SAFE_CLIB
* is defined) then space is allocated to save the C library context in the TCB.
*
* Allocating insufficient stack space is a common source of hard-to-find errors.
* During development, it is best to enable the FreeRTOS stack checking features.
*
* Usage:
*
* XT_USE_THREAD_SAFE_CLIB -- Define this to a nonzero value to enable thread-safe
* use of the C library. This will require extra stack
* space to be allocated for tasks that use the C library
* reentrant functions. See below for more information.
*
* NOTE: The Xtensa toolchain supports multiple C libraries and not all of them
* support thread safety. Check your core configuration to see which C library
* was chosen for your system.
*
* XT_STACK_MIN_SIZE -- The minimum stack size for any task. It is recommended
* that you do not use a stack smaller than this for any
* task. In case you want to use stacks smaller than this
* size, you must verify that the smaller size(s) will work
* under all operating conditions.
*
* XT_STACK_EXTRA -- The amount of extra stack space to allocate for a task
* that does not make C library reentrant calls. Add this
* to the amount of stack space required by the task itself.
*
* XT_STACK_EXTRA_CLIB -- The amount of space to allocate for C library state.
