93 depends on CMDLINE_BOOL
94 default "console=ttyUL0,115200"
96 On some architectures there is currently no way for the boot loader
97 to pass arguments to the kernel. For these architectures, you should
98 supply some command-line options at build time by entering them
102 bool "Force default kernel command string"
103 depends on CMDLINE_BOOL
106 Set this to have arguments from the default kernel command string
107 override those passed by the boot loader.
110 bool "Enable seccomp to safely compute untrusted bytecode"
114 This kernel feature is useful for number crunching applications
115 that may need to compute untrusted bytecode during their
116 execution. By using pipes or other transports made available to
117 the process as file descriptors supporting the read/write
118 syscalls, it's possible to isolate those applications in
119 their own address space using seccomp. Once seccomp is
120 enabled via /proc/<pid>/seccomp, it cannot be disabled
121 and the task is only allowed to execute a few safe syscalls
122 defined by each seccomp mode.
124 If unsure, say Y. Only embedded should say N here.

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

148 This is needed to be able to allocate uncachable memory regions.
149 The feature requires the design to define the RAM memory controller
150 window to be twice as large as the actual physical memory.
153 bool "High memory support"
156 The address space of Microblaze processors is only 4 Gigabytes large
157 and it has to accommodate user address space, kernel address
158 space as well as some memory mapped IO. That means that, if you
159 have a large amount of physical memory and/or IO, not all of the
160 memory can be "permanently mapped" by the kernel. The physical
161 memory that is not permanently mapped is called "high memory".
165 config LOWMEM_SIZE_BOOL
166 bool "Set maximum low memory"
167 depends on ADVANCED_OPTIONS && MMU
169 This option allows you to set the maximum amount of memory which
170 will be used as "low memory", that is, memory which the kernel can
171 access directly, without having to set up a kernel virtual mapping.
172 This can be useful in optimizing the layout of kernel virtual

188 If non-zero, a jump instruction to this address, will be written
189 to the reset vector at address 0x0.
190 If you are unsure, set it to default value 0x0.
192 config KERNEL_START_BOOL
193 bool "Set custom kernel base address"
194 depends on ADVANCED_OPTIONS
196 This option allows you to set the kernel virtual address at which
197 the kernel will map low memory (the kernel image will be linked at
198 this address). This can be useful in optimizing the virtual memory
199 layout of the system.
201 Say N here unless you know what you are doing.

208 config TASK_SIZE_BOOL
209 bool "Set custom user task size"
210 depends on ADVANCED_OPTIONS && MMU
212 This option allows you to set the amount of virtual address space
213 allocated to user tasks. This can be useful in optimizing the
214 virtual memory layout of the system.
216 Say N here unless you know what you are doing.
219 hex "Size of user task space" if TASK_SIZE_BOOL
224 default MICROBLAZE_4K_PAGES
225 depends on ADVANCED_OPTIONS && !MMU
227 Select the kernel logical page size. Increasing the page size
228 will reduce software overhead at each page boundary, allow
229 hardware prefetch mechanisms to be more effective, and allow
230 larger dma transfers increasing IO efficiency and reducing
231 overhead. However the utilization of memory will increase.
232 For example, each cached file will using a multiple of the
233 page size to hold its contents and the difference between the
234 end of file and the end of page is wasted.
236 If unsure, choose 4K_PAGES.
