help
On some architectures there is currently no way for the boot loader
to pass arguments to the kernel. For these architectures, you should
supply some command-line options at build time by entering them
here.

help
Set this to have arguments from the default kernel command string
override those passed by the boot loader.
config SECCOMP
bool "Enable seccomp to safely compute untrusted bytecode"
depends on PROC_FS
default y
help
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.
If unsure, say Y. Only embedded should say N here.

config ADVANCED_OPTIONS
bool "Prompt for advanced kernel configuration options"
help
This option will enable prompting for a variety of advanced kernel
configuration options. These options can cause the kernel to not
work if they are set incorrectly, but can be used to optimize certain
aspects of kernel memory management.
Unless you know what you are doing, say N here.

config XILINX_UNCACHED_SHADOW
bool "Are you using uncached shadow for RAM ?"
depends on ADVANCED_OPTIONS && !MMU
default n
help
This is needed to be able to allocate uncachable memory regions.
The feature requires the design to define the RAM memory controller
window to be twice as large as the actual physical memory.
config HIGHMEM
bool "High memory support"
depends on MMU
help
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".
If unsure, say n.
config LOWMEM_SIZE_BOOL
bool "Set maximum low memory"
depends on ADVANCED_OPTIONS && MMU
help
This option allows you to set the maximum amount of memory which
will be used as "low memory", that is, memory which the kernel can
access directly, without having to set up a kernel virtual mapping.
This can be useful in optimizing the layout of kernel virtual
memory.
Say N here unless you know what you are doing.

default "0x30000000"
config MANUAL_RESET_VECTOR
hex "Microblaze reset vector address setup"
default "0x0"
help
Set this option to have the kernel override the CPU Reset vector.
If zero, no change will be made to the MicroBlaze reset vector at
address 0x0.
If non-zero, a jump instruction to this address, will be written
to the reset vector at address 0x0.
If you are unsure, set it to default value 0x0.
config KERNEL_START_BOOL
bool "Set custom kernel base address"
depends on ADVANCED_OPTIONS
help
This option allows you to set the kernel virtual address at which
the kernel will map low memory (the kernel image will be linked at
this address). This can be useful in optimizing the virtual memory
layout of the system.
Say N here unless you know what you are doing.
config KERNEL_START

default "0xc0000000" if MMU
default KERNEL_BASE_ADDR if !MMU
config TASK_SIZE_BOOL
bool "Set custom user task size"
depends on ADVANCED_OPTIONS && MMU
help
This option allows you to set the amount of virtual address space
allocated to user tasks. This can be useful in optimizing the
virtual memory layout of the system.
Say N here unless you know what you are doing.

prompt "Page size"
default MICROBLAZE_4K_PAGES
depends on ADVANCED_OPTIONS && !MMU
help
Select the kernel logical page size. Increasing the page size
will reduce software overhead at each page boundary, allow
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
page size to hold its contents and the difference between the
end of file and the end of page is wasted.
If unsure, choose 4K_PAGES.
