|
|
If meta-data structures can be allocated from interrupt handlers,
|
|
then this specifies the number of pre-allocatd meta-data structures
|
|
that are reserved for for use only by interrupt handlers. This may
|
|
be zero to reserve no meta-data structures for interrupt handlers.
|
|
In that case, the allocation will fail if tasking logic has
|
|
allocated them all.
|
|
|
|
Interrupt logic will first attempt to allocate from the general,
|
|
pre-allocated structure pool that will contain up to (size
|
|
CONFIG_IEEE802154_IND_PREALLOC - CONFIG_IEEE802154_IND_IRQRESERVE)

entries. If that fails, then it will try to take a structure from
|
|
the reserve (size CONFIG_IEEE802154_IND_IRQRESERVE).
|
|
|
|
Non-interrupt logic will also first attempt to allocate from the
|
|
general, pre-allocated structure pool. If that fails, it will
|
|
dynamically allocate the meta data structure with an additional cost in performance.
