help
Loongson-3 processors have the llsc issues which require workarounds.
Without workarounds the system may hang unexpectedly.
- Newer Loongson-3 will fix these issues and no workarounds are needed.
- The workarounds have no significant side effect on them but may
- decrease the performance of the system so this option should be
- disabled unless the kernel is intended to be run on old systems.
-
- If unsure, please say Y.
+ Say Y, unless you know what you are doing.
