This table, unlike ISRs connected directly in the vector table, allow a parameter to be passed to the interrupt handlers. Also, invoking the exception/interrupt exit stub is automatically done. 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 XTENSA_RESET_VECTOR bool prompt "Build reset vector code" default y help This option controls whether the initial reset vector code is built. This is always needed for the simulator. Real boards may already implement this in boot ROM. config XTENSA_USE_CORE_CRT1 bool prompt "Use crt1.S from core" default y help SoC or boards might define their own __start by setting this setting to false. 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. config TOOLCHAIN_VARIANT string default RG-2016.4-linux source "arch/xtensa/soc/*/Kconfig" endmenu endmenu |
