	default 2000000

	help
	This option specifies hardware clock.

config XTENSA_NO_IPC
	bool "Core has no IPC support"
	select ATOMIC_OPERATIONS_C
	default n
	help
	Uncheck this if you core does not implment "SCOMPARE1" register and "s32c1i"
	isntruction.

config SW_ISR_TABLE
	bool
	prompt "Enable software interrupt handler table"
	default y
	help
	Enable an interrupt handler table implemented in software. This
	table, unlike ISRs connected directly in the vector table, allow
	a parameter to be passed to the interrupt handlers. Also, invoking
	the exeception/interrupt exit stub is automatically done.
	This has to be enabled for dynamically connecting interrupt handlers
	at runtime (SW_ISR_TABLE_DYNAMIC).

config IRQ_OFFLOAD
	bool "Enable IRQ offload"
	default n
	help
	Enable irq_offload() API which allows functions to be synchronously
	run in interrupt context. Uses one entry in the IDT.  Mainly useful
	for test cases.

config SW_ISR_TABLE_DYNAMIC
	bool
	prompt "Allow installing interrupt handlers at runtime"
	depends on SW_ISR_TABLE
	default n
	help
	This option enables irq_connect_dynamic(). It moves the ISR table to
	SRAM so that it is writable. This has the side-effect of removing
	write-protection on the ISR table.

menu "Specific core configuration"

config IRQ_OFFLOAD_INTNUM
	int
	prompt "IRQ offload SW interrupt index"
	help
	 The index of the software interrupt to be used for IRQ offload.

	 Please note that in order for IRQ offload to work correctly the selected
	 interrupt shall have its priority shall not exceed XCHAL_EXCM_LEVEL.
