92 string "Default kernel command string"
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.

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.

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

191 to the reset vector at address 0x0.
192 If you are unsure, set it to default value 0x0.

196 depends on ADVANCED_OPTIONS
198 This option allows you to set the kernel virtual address at which
199 the kernel will map low memory (the kernel image will be linked at
200 this address). This can be useful in optimizing the virtual memory
201 layout of the system.

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

226 default MICROBLAZE_4K_PAGES
227 depends on ADVANCED_OPTIONS && !MMU
229 Select the kernel logical page size. Increasing the page size
230 will reduce software overhead at each page boundary, allow
231 hardware prefetch mechanisms to be more effective, and allow
232 larger dma transfers increasing IO efficiency and reducing
233 overhead. However the utilization of memory will increase.
234 For example, each cached file will using a multiple of the
235 page size to hold its contents and the difference between the
236 end of file and the end of page is wasted.
238 If unsure, choose 4K_PAGES.
