Build a minimal JSON parsing/encoding library. Used by sample
|
|
applications such as the NATS client.

config RING_BUFFER

bool "Enable ring buffers"
|
|
help
|
|
Enable usage of ring buffers. This is similar to kernel FIFOs but ring
|
|
buffers manage their own buffer memory and can store arbitrary data.
|
|
For optimal performance, use buffer sizes that are a power of 2.

help
|
|
The sys_heap implementation is instrumented for extensive
|
|
internal validation. Leave this off by default, unless
|
|
modifying the heap code or (maybe) when running in
|
|
environments that require sensitive detection of memory
|
|
corruption.

config SYS_HEAP_ALLOC_LOOPS
|
|
int "Number of tries in the inner heap allocation loop"
|
|
default 3
|
|
help
|
|
The sys_heap allocator bounds the number of tries from the
|
|
smallest chunk level (the one that might not fit the
|
|
requested allocation) to maintain constant time performance.
|
|
Setting this to a high level will cause the heap to return
|
|
more successful allocations in situations of high
|
|
fragmentation, at the cost of potentially significant
|
|
(linear time) searching of the free list. The default is
|
|
three, which results in an allocator with good statistical
|
|
properties ("most" allocations that fit will succeed) but
|
|
keeps the maximum runtime at a tight bound so that the heap
|
|
is useful in locked or ISR contexts.

help
|
|
When true, a spinlock will be taken around the output from a
|
|
single printk() call, preventing the output data from
|
|
interleaving with concurrent usage from another CPU or an
|
|
preempting interrupt.
