|
|
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.

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.
