help
|

The address space of Meta processors is only 4 Gigabytes large
|
||||
and it has to accommodate user address space, kernel address
|
||||
space as well as some memory mapped IO. That means that, if you
|
||||
have a large amount of physical memory and/or IO, not all of the
|
||||
memory can be "permanently mapped" by the kernel. The physical
|
||||
memory that is not permanently mapped is called "high memory".
|
||||
|
||||
Depending on the selected kernel/user memory split, minimum
|
||||
vmalloc space and actual amount of RAM, you may not need this
|
||||
option which should result in a slightly faster kernel.
|
||||
|
||||
If unsure, say n.

Some Meta systems have MMU-mappable on-chip memories with

lower latencies than main memory. This enables support for

|

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.

The page size is not necessarily 4KB. Keep this in mind

Press y here to enable support for the Meta Level 2 (L2) cache. This
|

will enable the cache at start up if it hasn't already been enabled
|

by the bootloader.
|
||||
|
||||
If the bootloader enables the L2 you must press y here to ensure the
|
||||
kernel takes the appropriate actions to keep the cache coherent.
