INTERRUPT/EXCEPTION STACK FRAME FOR A THREAD OR NESTED INTERRUPT

A stack frame of this structure is allocated for any interrupt or exception.

It goes on the current stack. If the RTOS has a system stack for handling

interrupts, every thread stack must allow space for just one interrupt stack
|

frame, then nested interrupt stack frames go on the system stack.

|

The frame includes basic registers (explicit) and "extra" registers introduced

by user TIE or the use of the MAC16 option in the user's Xtensa config.
|
||||
The frame size is minimized by omitting regs not applicable to user's config.
|
||||
|
||||
For Windowed ABI, this stack frame includes the interruptee's base save area,
|

another base save area to manage gcc nested functions, and a little temporary

||||
space to help manage the spilling of the register windows.

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
|
||||
Pointer to the aligned save area. Allows it to be aligned more than
|
||||
the overall save area (which might only be stack-aligned or TCB-aligned).
|
||||
Especially relevant for Xtensa cores configured with a very large data
|
||||
path that requires alignment greater than 16 bytes (ABI stack alignment).

MACROS TO HANDLE ABI SPECIFICS OF FUNCTION ENTRY AND RETURN
|
||||
|
||||
Convenient where the frame size requirements are the same for both ABIs.
|
||||
ENTRY(sz), RET(sz) are for framed functions (have locals or make calls).
|
||||
ENTRY0, RET0 are for frameless functions (no locals, no calls).
|
||||
|
||||
where size = size of stack frame in bytes (must be >0 and aligned to 16).
|
||||
For framed functions the frame is created and the return address saved at
|
||||
base of frame (Call0 ABI) or as determined by hardware (Windowed ABI).
|
||||
For frameless functions, there is no frame and return address remains in a0.
|
||||
Note: Because CPP macros expand to a single line, macros requiring multi-line
|
||||
expansions are implemented as assembler macros.
