SOLICITED STACK FRAME FOR A THREAD
|
||||
|
||||
A stack frame of this structure is allocated whenever a thread enters the
|
||||
RTOS kernel intentionally (and synchronously) to submit to thread scheduling.
|
||||
It goes on the current thread's stack.
|
||||
|
||||
The solicited frame only includes registers that are required to be preserved
|
||||
by the callee according to the compiler's ABI conventions, some space to save
|
||||
the return address for returning to the caller, and the caller's PS register.
|
||||
|
||||
For Windowed ABI, this stack frame includes the caller's base save area.
|
||||
|
||||
Note on XT_SOL_EXIT field:
|
||||
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)
|
||||
to distinguish a solicted frame from an interrupt frame. An RTOS port may
|
||||
opt to ignore this field if it has another way of distinguishing frames.
