CONFIG_X86_KERNEL_OOPS_VECTOR¶

IDT vector to use for kernel oops

Type: int

Help¶

Specify the IDT vector to use for the kernel oops exception handler. The default should be fine for most arches, but on systems like MVIC where there is a fixed IRQ-to-vector mapping another value may be needed to avoid collision.

Direct dependencies¶

X86_KERNEL_OOPS && X86

(Includes any dependencies from if’s and menus.)

Defaults¶

62 if MVIC && X86_KERNEL_OOPS && X86
33 if !MVIC && X86_KERNEL_OOPS && X86

Kconfig definition¶

At arch/x86/Kconfig:318

Included via Kconfig:10 → Kconfig.zephyr:29 → arch/Kconfig:15

Menu path: (top menu) → X86 Architecture Options → Processor Capabilities
