CONFIG_DYNAMIC_DIRECT_INTERRUPTS

Enable support for dynamic direct interrupts

Type: bool

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.
