158 prompt "CPU Caching mode"
159 default FRV_DEFL_CACHE_WBACK
160 help
161 This option determines the default caching mode for the kernel.
162
163 Write-Back caching mode involves the all reads and writes causing
164 the affected cacheline to be read into the cache first before being
165 operated upon. Memory is not then updated by a write until the cache
166 is filled and a cacheline needs to be displaced from the cache to
167 make room. Only at that point is it written back.
168
169 Write-Behind caching is similar to Write-Back caching, except that a
170 write won't fetch a cacheline into the cache if there isn't already
171 one there; it will write directly to memory instead.
172
173 Write-Through caching only fetches cachelines from memory on a
174 read. Writes always get written directly to memory. If the affected
175 cacheline is also in cache, it will be updated too.
176
177 The final option is to turn of caching entirely.
178
179 Note that not all CPUs support Write-Behind caching. If the CPU on
180 which the kernel is running doesn't, it'll fall back to Write-Back
181 caching.
