It is necessary to distinguish a solicited from an interrupt stack frame.
This field corresponds to XT_STK_EXIT in the interrupt stack frame and is
always at the same offset (0). It can be written with a code (usually 0)

opt to ignore this field if it has another way of distinguishing frames.

/*******************************************************************************
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.

sources and a specific RTOS port for Xtensa. It contains definitions
and macros for use primarily by Xtensa assembly coded source files.
Macros in this header map callouts from generic Xtensa files to specific
RTOS functions. It may also be included in C source files.
Xtensa RTOS ports support all RTOS-compatible configurations of the Xtensa
architecture, using the Xtensa hardware abstraction layer (HAL) to deal
with configuration specifics.
Should be included by all Xtensa generic and RTOS port-specific sources.

/*******************************************************************************
HOOKS TO DYNAMICALLY INSTALL INTERRUPT AND EXCEPTION HANDLERS PER LEVEL.
This Xtensa RTOS port provides hooks for dynamically installing exception
and interrupt handlers to facilitate automated testing where each test
case can install its own handler for user exceptions and each interrupt
priority (level). This consists of an array of function pointers indexed
by interrupt priority, with index 0 being the user exception handler hook.
Each entry in the array is initially 0, and may be replaced by a function
pointer of type XT_INTEXC_HOOK. A handler may be uninstalled by installing 0.
The handler for low and medium priority obeys ABI conventions so may be coded
in C. For the exception handler, the cause is the contents of the EXCCAUSE
reg, and the result is -1 if handled, else the cause (still needs handling).
For interrupt handlers, the cause is a mask of pending enabled interrupts at
that level, and the result is the same mask with the bits for the handled
interrupts cleared (those not cleared still need handling). This allows a test
case to either pre-handle or override the default handling for the exception
or interrupt level (see xtensa_vectors.S).
High priority handlers (including NMI) must be coded in assembly, are always
called by 'call0' regardless of ABI, must preserve all registers except a0,
and must not use or modify the interrupted stack. The hook argument 'cause'
is not passed and the result is ignored, so as not to burden the caller with
saving and restoring a2 (it assumes only one interrupt per level - see the
discussion in high priority interrupts in xtensa_vectors.S). The handler
therefore should be coded to prototype 'void h(void)' even though it plugs
into an array of handlers of prototype 'unsigned h(unsigned)'.
To enable interrupt/exception hooks, compile the RTOS with '-DXT_INTEXC_HOOKS'.

XTENSA INFORMATION FOR RTOS TICK TIMER AND CLOCK FREQUENCY
This header contains definitions and macros for use primarily by Xtensa
RTOS assembly coded source files. It includes and uses the Xtensa hardware
abstraction layer (HAL) to deal with config specifics. It may also be
included in C source files.
User may edit to modify timer selection and to specify clock frequency and
tick duration to match timer interrupt to the real-time tick duration.
If the RTOS has no timer interrupt, then there is no tick timer and the
clock frequency is irrelevant, so all of these macros are left undefined
and the Xtensa core configuration need not have a timer.

NOTE ON SIMULATOR:
Under the Xtensa instruction set simulator, the frequency can only be estimated
because it depends on the speed of the host and the version of the simulator.
Also because it runs much slower than hardware, it is not possible to achieve
real-time performance for most applications under the simulator. A frequency
too low does not allow enough time between timer interrupts, starving threads.
To obtain a more convenient but non-real-time tick duration on the simulator,
compile with xt-xcc option "-DXT_SIMULATOR".
