|

|

|
* normal processing but execute outside of OS (although they can "get back
|
|
* into the game" via a PendSV interrupt).
|
|
*
|
|
* In the normal course of things, interrupts must occasionally be disabled
|
|
* using the irqsave() inline function to prevent contention in use of
|
|
* resources that may be shared between interrupt level and non-interrupt
|
|
* level logic. Now the question arises, if CONFIG_ARCH_HIPRI_INTERRUPT,
|
|
* do we disable all interrupts (except SVCall), or do we only disable the
|
|
* "normal" interrupts. Since the high priority interrupts cannot interact
|
|
* with the OS, you may want to permit the high priority interrupts even if
