* Kernel preemption: implementation details.
|
||||
*
|
||||
* The kernel preemption is implemented using the PendSV IRQ. Inside the
|
||||
* SysTick handler when a process needs to be interrupted (expires its time
|
||||
* quantum or a high-priority process is awakend) a pending PendSV call is
|
||||
* triggered.
|
||||
*
|
||||
* The PendSV handler is called immediately after the SysTick handler, using
|
||||
* the architecture's tail-chaining functionality (an ISR call without the
|
||||
* overhead of state saving and restoration between different IRQs). Inside the
|
||||
* PendSV handler we perform the stack-switching between the old and new
|
||||
* processes.
|
||||
*
|
||||
* Voluntary context switch is implemented as a soft-interrupt call (SVCall),
|
||||
* so any process is always suspended and resumed from an interrupt context.
|
||||
*
|
||||
* NOTE: interrupts must be disabled or enabled when resuming a process context
|
||||
* depending of the type of the previous suspension. If a process was suspended
|
||||
* by a voluntary context switch IRQs must be disabled on resume (voluntary
|
||||
* context switch always happen with IRQs disabled). Instead, if a process was
|
||||
* suspended by the kernel preemption IRQs must be always re-enabled, because
|
||||
* the PendSV handler resumes directly the process context. To keep track of
|
||||
* this, we save the state of the IRQ priority in register r3 before performing
|
||||
* the context switch.
|
||||
*
|
||||
* If CONFIG_KERN_PREEMPT is not enabled the cooperative implementation
|
||||
* fallbacks to the default stack-switching mechanism, performed directly in
|
||||
* thread-mode and implemented as a normal function call.
