The kernel memory allocator divides physically contiguous memory
|
|
blocks into "zones", where each zone is a power of two number of
|
|
pages. This option selects the largest power of two that the kernel
|
|
keeps in the memory allocator. If you need to allocate very large
|
|
blocks of physically contiguous memory, then you may need to
|
|
increase this value.
|
|
|
|
This config option is actually maximum order plus one. For example,
|
|
a value of 11 means that the largest free memory block is 2^10 pages.

Nios II CPUs cannot fetch/store data which is not bus aligned,

i.e., a 2 or 4 byte fetch must start at an address divisible by

emulated in software if you say Y here, which has a performance

impact.

On some platforms, there is currently no way for the boot loader to

pass arguments to the kernel. For these platforms, you can supply

some command-line options at build time by entering them here. In

to set them up in board prom initialization routines.
