This kernel feature is useful for number crunching applications

that may need to compute untrusted bytecode during their

|
execution. By using pipes or other transports made available to
|
|
the process as file descriptors supporting the read/write
|
|
syscalls, it's possible to isolate those applications in
|
|
their own address space using seccomp. Once seccomp is
|
|
enabled via /proc/<pid>/seccomp, it cannot be disabled
|
|
and the task is only allowed to execute a few safe syscalls
|

defined by each seccomp mode.

The address space of Microblaze 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".

Select the kernel logical page size. Increasing the page size

hardware prefetch mechanisms to be more effective, and allow

larger dma transfers increasing IO efficiency and reducing

overhead. However the utilization of memory will increase.

For example, each cached file will using a multiple of the
