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.
