CONFIG_ARC_FIRQ_STACK
¶
Enable separate firq stack
Type: bool
Help¶
Use separate stack for FIRQ handing. When the fast irq is also a direct irq, this will get the minimal interrupt latency.
Direct dependencies¶
ARC_FIRQ
&& RGF_NUM_BANKS
> 1 && ARC
(Includes any dependencies from ifs and menus.)
Defaults¶
