|
|
---help---
|

This specifies the total number of preallocated buffer structures.

This is for performance optimization. If additional buffer structures

are needed, they will be allocated dynamically at some loss of

performance.

config BLUETOOTH_BUFFER_IRQRESERVE
|

int "Reserved pre-allocated primitive structures"

default 0
|
|
---help---
|
|
If buffer structures can be allocated from interrupt handlers, then
|
|
this specifies the number of pre-allocated structures that are
|
|
reserved for for use only by interrupt handlers. This may be set
|
|
zero to reserve no buffers 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 buffer pool that will contain up to (size
|
|
CONFIG_BLUETOOTH_BUFFER_PREALLOC - BLUETOOTH_BUFFER_IRQRESERVE)
|
|
entries. If that fails, then it will try to take a buffer from
|
|
the reserve (size CONFIG_BLUETOOTH_BUFFER_IRQRESERVE).
|
|
|
|
Non-interrupt logic will also first attempt to allocate from the
|
|
general, pre-allocated buffer pool. If that fails, it will
|
|
dynamically allocate the buffer with an additional cost in
|
|
performance.
|
|
|
|
NOTE: The Bluetooth stack never allocates buffers from the
|
|
interrupt level. This setting only needs to be non-zero if your
|
|
low-level Bluetooth driver needs to do such allocations.
