| prompt "CPU Caching mode" |
| default MN10300_CACHE_WBACK |
| help |
| This option determines the caching mode for the kernel. |
| |
| Write-Back caching mode involves the all reads and writes causing |
| the affected cacheline to be read into the cache first before being |
| operated upon. Memory is not then updated by a write until the cache |
| is filled and a cacheline needs to be displaced from the cache to |
| make room. Only at that point is it written back. |
| |
| Write-Through caching only fetches cachelines from memory on a |
| read. Writes always get written directly to memory. If the affected |
| cacheline is also in cache, it will be updated too. |
| |
| The final option is to turn of caching entirely. |

| config PREEMPT |
| bool "Preemptible Kernel" |
| help |
| This option reduces the latency of the kernel when reacting to |
| real-time or interactive events by allowing a low priority process to |
| be preempted even if it is in kernel mode executing a system call. |
| This allows applications to run more reliably even when the system is |
| under load. |
| |
| Say Y here if you are building a kernel for a desktop, embedded |
| or real-time system. Say N if you are unsure. |
| |
| config MN10300_CURRENT_IN_E2 |
| bool "Hold current task address in E2 register" |
| default y |
| help |
| This option removes the E2/R2 register from the set available to gcc |
| for normal use and instead uses it to store the address of the |
| current process's task_struct whilst in the kernel. |
| |
| This means the kernel doesn't need to calculate the address each time |
| "current" is used (take SP, AND with mask and dereference pointer |
| just to get the address), and instead can just use E2+offset |
| addressing each time. |
| |
| This has no effect on userspace. |
| |
| config MN10300_USING_JTAG |
| bool "Using JTAG to debug kernel" |

| single-stepping, which are taken over completely by the JTAG unit. |

| help |
| Some systems (such as the ASB2305) have PCI onboard. If you have one |
| of these boards and you wish to use the PCI facilities, say Y here. |
