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

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

177 This option allows you to set the maximum amount of memory which
178 will be used as "low memory", that is, memory which the kernel can
179 access directly, without having to set up a kernel virtual mapping.
180 This can be useful in optimizing the layout of kernel virtual

202 depends on ADVANCED_OPTIONS
204 This option allows you to set the kernel virtual address at which
205 the kernel will map low memory (the kernel image will be linked at
206 this address). This can be useful in optimizing the virtual memory
207 layout of the system.

221 allocated to user tasks. This can be useful in optimizing the
222 virtual memory layout of the system.

227 hex "Size of user task space" if TASK_SIZE_BOOL
232 default MICROBLAZE_4K_PAGES
233 depends on ADVANCED_OPTIONS && !MMU
235 Select the kernel logical page size. Increasing the page size
236 will reduce software overhead at each page boundary, allow
237 hardware prefetch mechanisms to be more effective, and allow
238 larger dma transfers increasing IO efficiency and reducing
239 overhead. However the utilization of memory will increase.
240 For example, each cached file will using a multiple of the
241 page size to hold its contents and the difference between the
242 end of file and the end of page is wasted.
244 If unsure, choose 4K_PAGES.
