128 | help | |
129 | This option determines the caching mode for the kernel. | |
130 | ||
131 | Write-Back caching mode involves the all reads and writes causing | |
132 | the affected cacheline to be read into the cache first before being | |
133 | operated upon. Memory is not then updated by a write until the cache | |
134 | is filled and a cacheline needs to be displaced from the cache to | |
135 | make room. Only at that point is it written back. | |
136 | ||
137 | Write-Through caching only fetches cachelines from memory on a | |
138 | read. Writes always get written directly to memory. If the affected | |
139 | cacheline is also in cache, it will be updated too. | |

177 | config PREEMPT | |
178 | bool "Preemptible Kernel" | |
179 | help | |
180 | This option reduces the latency of the kernel when reacting to | |
181 | real-time or interactive events by allowing a low priority process to | |
182 | be preempted even if it is in kernel mode executing a system call. | |
183 | This allows applications to run more reliably even when the system is | |
184 | under load. | |
185 | ||
186 | Say Y here if you are building a kernel for a desktop, embedded | |
187 | or real-time system. Say N if you are unsure. | |

190 | bool "Hold current task address in E2 register" | |
191 | default y | |
192 | help | |
193 | This option removes the E2/R2 register from the set available to gcc | |
194 | for normal use and instead uses it to store the address of the | |
195 | current process's task_struct whilst in the kernel. | |
196 | ||
197 | This means the kernel doesn't need to calculate the address each time | |
198 | "current" is used (take SP, AND with mask and dereference pointer | |
199 | just to get the address), and instead can just use E2+offset | |
200 | addressing each time. | |
