* Implementation of functions defined in portable.h for the Posix port.
*
* Each task has a pthread which eases use of standard debuggers
* (allowing backtraces of tasks etc). Threads for tasks that are not
* running are blocked in sigwait().
*
* Task switch is done by resuming the thread for the next task by
* sending it the resume signal (SIGUSR1) and then suspending the
* current thread.
*
* The timer interrupt uses SIGALRM and care is taken to ensure that
* the signal handler runs only on the thread for the current task.
*
* Use of part of the standard C library requires care as some
* functions can take pthread mutexes internally which can result in
* deadlocks as the FreeRTOS kernel can switch tasks while they're
* holding a pthread mutex.
*
* Replacement malloc(), free(), calloc(), and realloc() are provided
* for glibc (see below for more information).
*
* stdio (printf() and friends) should be called from a single task
* only or serialized with a FreeRTOS primitive such as a binary
* semaphore or mutex.

* STACK REQUIREMENTS
*
* This section defines the minimum stack size, and the extra space required to

*
* 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

CO-PROCESSOR STATE SAVE AREA FOR A THREAD
The RTOS must provide an area per thread to save the state of co-processors
when that thread does not have control. Co-processors are context-switched
lazily (on demand) only when a new thread uses a co-processor instruction,
otherwise a thread retains ownership of the co-processor even when it loses
control of the processor. An Xtensa co-processor exception is triggered when
any co-processor instruction is executed by a thread that is not the owner,
and the context switch of that co-processor is then peformed by the handler.
Ownership represents which thread's state is currently in the co-processor.
Co-processors may not be used by interrupt or exception handlers. If an
co-processor instruction is executed by an interrupt or exception handler,
the co-processor exception handler will trigger a kernel panic and freeze.
This restriction is introduced to reduce the overhead of saving and restoring
co-processor state (which can be quite large) and in particular remove that
overhead from interrupt handlers.
The co-processor state save area may be in any convenient per-thread location
such as in the thread control block or above the thread stack area. It need
not be in the interrupt stack frame since interrupts don't use co-processors.
Along with the save area for each co-processor, two bitmasks with flags per
co-processor (laid out as in the CPENABLE reg) help manage context-switching
co-processors as efficiently as possible:
XT_CPENABLE
The contents of a non-running thread's CPENABLE register.
It represents the co-processors owned (and whose state is still needed)
by the thread. When a thread is preempted, its CPENABLE is saved here.
When a thread solicits a context-swtich, its CPENABLE is cleared - the
compiler has saved the (caller-saved) co-proc state if it needs to.
When a non-running thread loses ownership of a CP, its bit is cleared.
When a thread runs, it's XT_CPENABLE is loaded into the CPENABLE reg.
Avoids co-processor exceptions when no change of ownership is needed.
XT_CPSTORED
A bitmask with the same layout as CPENABLE, a bit per co-processor.
Indicates whether the state of each co-processor is saved in the state
save area. When a thread enters the kernel, only the state of co-procs
still enabled in CPENABLE is saved. When the co-processor exception
handler assigns ownership of a co-processor to a thread, it restores
the saved state only if this bit is set, and clears this bit.
XT_CP_CS_ST
A bitmask with the same layout as CPENABLE, a bit per co-processor.
Indicates whether callee-saved state is saved in the state save area.
Callee-saved state is saved by itself on a solicited context switch,
and restored when needed by the coprocessor exception handler.
Unsolicited switches will cause the entire coprocessor to be saved
when necessary.
XT_CP_ASA
