config JSON_LIBRARY
bool "Build JSON library"
help
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.
config BASE64
bool "Enable base64 encoding and decoding"
help
Enable base64 encoding and decoding functionality
config SYS_HEAP_VALIDATE
bool "Enable internal heap validity checking"
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.
