61 This can be set to 0 to disable preemptible scheduling.
88 This defines the minimum priority value (i.e. the logically
96 This defines a set of priorities at the (numerically) lowest

116 This enables a simple "earliest deadline first" scheduling
130 implemented, this involves an inherent O(N) scaling in the number of
134 Note that this setting does not technically depend on SMP and is
147 scheduled symmetrically. In general this is not helpful,
155 applications don't want this.

463 This option outputs a banner to the console device during boot up.
470 Use this option to set the boot banner.
477 This option delays bootup for the specified amount of
478 milliseconds. This is used to allow serial ports to get ready
489 Use this option to clear the screen before printing anything else.
490 Using a VT100 enabled terminal on the client side is required for this to work.

568 When set, this option automatically enables the gathering of both
591 priority. This means that any work handler, once started, won't
598 prevent other threads from being starved. Selecting this removes

651 This option enables time slicing between preemptible threads of
660 This option specifies the maximum amount of time a thread can execute
671 This option specifies the thread priority level at which time slicing
672 takes effect; threads having a higher priority than this ceiling are
679 When set, this enables an API for setting timeslice values on
699 This enables additional runtime checks to validate the memory slab
705 This adds variable to the k_mem_slab structure to hold

806 This option specifies the nominal frequency of the system clock in Hz.
814 The choice of tick rate is configurable by this option. Also the number
822 this config variable specifies the minimum available timing
832 This option specifies the frequency of the hardware timer used for the
833 system clock (in Hz). This option is set by the SOC's or board's Kconfig file

918 This option enables compiler stack canaries in functions that have

928 This option enables compiler stack canaries in functions that call alloca,
938 This option enables compiler stack canaries for all functions.
947 This option enables compiler stack canaries only in functions which have the
959 This option enables compiler stack canaries on TLS.
962 each thread will have its own canary. This makes harder
965 When enabled this causes an additional performance penalty
977 and vice versa. This might not be acceptable in all scenarios,
978 so this option is given for those unafraid of shooting themselves
