| help |
| This enables a sysfs driver that provides access to the CPU core level |
| 2 cache configuration (information like line size, ways of |
| associativity, total size, whether unified, and the hardware revision |
| number). It also provides controls to enable and disable the L2 cache, |
| to enable and disable prefetch, and to trigger write backs and |
| flushes, mostly for debug purposes. They can be found in |
| /sys/devices/system/cache/l2/. |
