| 153 | help |
| 154 | This option determines the default caching mode for the kernel. |
| 155 | |
| 156 | Write-Back caching mode involves the all reads and writes causing |
| 157 | the affected cacheline to be read into the cache first before being |
| 158 | operated upon. Memory is not then updated by a write until the cache |
| 159 | is filled and a cacheline needs to be displaced from the cache to |
| 160 | make room. Only at that point is it written back. |
| 161 | |
| 162 | Write-Behind caching is similar to Write-Back caching, except that a |
| 163 | write won't fetch a cacheline into the cache if there isn't already |
| 164 | one there; it will write directly to memory instead. |
| 165 | |
| 166 | Write-Through caching only fetches cachelines from memory on a |
| 167 | read. Writes always get written directly to memory. If the affected |
| 168 | cacheline is also in cache, it will be updated too. |
| 169 | |
| 170 | The final option is to turn of caching entirely. |
| 171 | |
| 172 | Note that not all CPUs support Write-Behind caching. If the CPU on |
