Help¶

Direct interrupts are designed for performance-critical interrupt handling and do not go through all of the common interrupt handling code. This option enables the installation of interrupt service routines for direct interrupts at runtime. Note: this requires enabling support for dynamic interrupts in the kernel.

Direct dependencies¶

DYNAMIC_INTERRUPTS && (ARMV6_M_ARMV8_M_BASELINE || ARMV7_M_ARMV8_M_MAINLINE) && CPU_CORTEX_M && !ARM64 && ARM

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
