142 | help | |
143 | This option determines the caching mode for the kernel. | |
144 | ||
145 | Write-Back caching mode involves the all reads and writes causing | |
146 | the affected cacheline to be read into the cache first before being | |
147 | operated upon. Memory is not then updated by a write until the cache | |
148 | is filled and a cacheline needs to be displaced from the cache to | |
149 | make room. Only at that point is it written back. | |
150 | ||
151 | Write-Through caching only fetches cachelines from memory on a | |
152 | read. Writes always get written directly to memory. If the affected | |
153 | cacheline is also in cache, it will be updated too. | |

191 | config PREEMPT | |
192 | bool "Preemptible Kernel" | |
193 | help | |
194 | This option reduces the latency of the kernel when reacting to | |
195 | real-time or interactive events by allowing a low priority process to | |
196 | be preempted even if it is in kernel mode executing a system call. | |
197 | This allows applications to run more reliably even when the system is | |
198 | under load. | |
199 | ||
200 | Say Y here if you are building a kernel for a desktop, embedded | |
201 | or real-time system. Say N if you are unsure. | |

204 | bool "Hold current task address in E2 register" | |
205 | default y | |
206 | help | |
207 | This option removes the E2/R2 register from the set available to gcc | |
208 | for normal use and instead uses it to store the address of the | |
209 | current process's task_struct whilst in the kernel. | |
210 | ||
211 | This means the kernel doesn't need to calculate the address each time | |
212 | "current" is used (take SP, AND with mask and dereference pointer | |
213 | just to get the address), and instead can just use E2+offset | |
214 | addressing each time. | |
