123 default MN10300_CACHE_WBACK
124 help
125 This option determines the caching mode for the kernel.
126
127 Write-Back caching mode involves the all reads and writes causing
128 the affected cacheline to be read into the cache first before being
129 operated upon. Memory is not then updated by a write until the cache
130 is filled and a cacheline needs to be displaced from the cache to
131 make room. Only at that point is it written back.
132
133 Write-Through caching only fetches cachelines from memory on a
134 read. Writes always get written directly to memory. If the affected
135 cacheline is also in cache, it will be updated too.
136
137 The final option is to turn of caching entirely.

173config PREEMPT
174 bool "Preemptible Kernel"
175 help
176 This option reduces the latency of the kernel when reacting to
177 real-time or interactive events by allowing a low priority process to
178 be preempted even if it is in kernel mode executing a system call.
179 This allows applications to run more reliably even when the system is
180 under load.

196config MN10300_CURRENT_IN_E2
197 bool "Hold current task address in E2 register"
198 default y
199 help
200 This option removes the E2/R2 register from the set available to gcc
201 for normal use and instead uses it to store the address of the
202 current process's task_struct whilst in the kernel.
203
204 This means the kernel doesn't need to calculate the address each time
205 "current" is used (take SP, AND with mask and dereference pointer
206 just to get the address), and instead can just use E2+offset
207 addressing each time.
208
209 This has no effect on userspace.
