| 132 | help |
| 133 | This option determines the caching mode for the kernel. |
| 134 | |
| 135 | Write-Back caching mode involves the all reads and writes causing |
| 136 | the affected cacheline to be read into the cache first before being |
| 137 | operated upon. Memory is not then updated by a write until the cache |
| 138 | is filled and a cacheline needs to be displaced from the cache to |
| 139 | make room. Only at that point is it written back. |
| 140 | |
| 141 | Write-Through caching only fetches cachelines from memory on a |
| 142 | read. Writes always get written directly to memory. If the affected |
| 143 | cacheline is also in cache, it will be updated too. |

| 183 | help |
| 184 | This option reduces the latency of the kernel when reacting to |
| 185 | real-time or interactive events by allowing a low priority process to |
| 186 | be preempted even if it is in kernel mode executing a system call. |

| 188 | under load. |

| 197 | This option removes the E2/R2 register from the set available to gcc |
| 198 | for normal use and instead uses it to store the address of the |
| 199 | current process's task_struct whilst in the kernel. |
| 200 | |
| 201 | This means the kernel doesn't need to calculate the address each time |
| 202 | "current" is used (take SP, AND with mask and dereference pointer |
| 203 | just to get the address), and instead can just use E2+offset |
