CONFIG_ARC_FIRQ

FIRQ enable

Type: bool

Help

Fast interrupts are supported (FIRQ). If FIRQ enabled, for interrupts
with highest priority, status32 and pc will be saved in aux regs,
other regs will be saved according to the number of register bank;
If FIRQ is disabled, the handle of interrupts with highest priority
will be same with other interrupts.
NOTE: we don't allow the configuration with FIRQ enabled and only one
interrupt priority level (so all interrupts are FIRQ). Such
configuration isn't supported in software and it is not beneficial
from the performance point of view.
