post	3.3 Kconfig	3. Threads

Kconfig

Threads are always included in the system configuration, therefore no additional configs need to be set.

However optionally the following configuration options can be set:

Kconfig	Description
CONFIG_MAIN_THREAD_PRIORITY	Priority of initialization/main thread
CONFIG_MAIN_STACK_SIZE	Size of stack for initialization and main thread
CONFIG_IDLE_STACK_SIZE	Size of stack for idle thread
CONFIG_THREAD_CUSTOM_DATA	This option allows each thread to store 32 bits of custom data, which can be accessed using the k_thread_custom_data_xxx() APIs.
CONFIG_NUM_COOP_PRIORITIES	Number of cooperative priorities configured in the system
CONFIG_NUM_PREEMPT_PRIORITIES	Number of preemptible priorities available in the system
CONFIG_TIMESLICING	This option enables time slicing between preemptible threads of equal priority.
CONFIG_TIMESLICE_SIZE	This option specifies the maximum amount of time a thread can execute before other threads of equal priority are given an opportunity to run. A time slice size of zero means "no limit" (i.e. an infinitely large time slice).
CONFIG_TIMESLICE_PRIORITY	This option specifies the thread priority level at which time slicing takes effect; threads having a higher priority than this ceiling are not subject to time slicing.
CONFIG_USERSPACE	When enabled, threads may be created or dropped down to user mode, which has significantly restricted permissions and must interact with the kernel via system calls.
